The seven PYP key concepts explained: form, function, causation, change, connection, perspective and responsibility. Practical inquiry prompts for primary teachers, plus why the Enhanced PYP now treats reflection as an embedded process.
PYP Key Concepts: 7 Lenses for Inquiry-Based Teaching explains the seven specified concepts in the International Baccalaureate Primary Years Programme. These concepts help learners organise inquiry: form, function, causation, change, connection, perspective and responsibility. They are not lesson topics or a planning checklist. They are recurring lenses for asking better questions, building conceptual language and transferring understanding across transdisciplinary themes.
For example, in a Year 4 water systems unit, learners might use causation to examine flooding, connection to link land use and drainage, and responsibility to debate local action. The sequence matters: young learners need enough concrete knowledge and vocabulary before open inquiry, or the conceptual load can exceed working memory (Sweller, 1988). The older PYP listed eight key concepts, including Reflection. The Enhanced PYP (2018) repositioned reflection as a continuous practice within inquiry, assessment and action, not as a separate lens. Many school websites still say 8 in 2026; this article follows the current seven.
The 7 PYP key concepts serve as powerful lenses that transform how learners explore and understand their world through inquiry-based learning. These conceptual frameworks, form, function, causation, change, connection, perspective, and responsibility, guide young learners aged 3-12 to dig deeper than surface-level facts and discover the underlying patterns that connect all knowledge. Rather than simply memorising information, learners learn to ask meaningful questions and make connections across subjects, developing critical thinking skills that extend far beyond the classroom. Understanding how these seven lenses work together can transform your approach to inquiry-based teaching and develop your learners' potential as lifelong learners.
Evidence overview
The Primary Years Programme helps develop learners aged 3-12. It uses six themes and seven concepts. This framework prepares learners for lifelong inquiry-based learning (Wiggins & McTighe, 2005). Learners may continue with the Middle Years Programme and IB Diploma Programme.
The PYP framework is organised around six subject areas: Language, Mathematics, Science, Social Studies, Arts, and Personal, Social and Physical Education. These subjects are explored through six transdisciplinary themes: Who we are; Where we are in place and time; How we express ourselves; How the world works; How we organise ourselves; and Sharing the planet. This structure allows learners to make connections across traditional subject boundaries while developing conceptual understanding through the 7 key concepts.
The PYP has five parts: knowledge, concepts, skills, attitudes, and action. These elements help learners aged 3-12 become globally aware (PYP framework). These elements create active learning and work across all subjects. (PYP framework).
The PYP framework includes 5 needed elements:
These elements are created through 6 themes which are applicable across all of the subjects. The themes include:
The breadth of knowledge is investigated from global and local perspectives within a unit of inquiry. The IB standards are supported by an effective approach to teaching and follow best practices in education. Experienced educators collaborate while planning units of inquiry both as a whole faculty and as grade teachers belonging to any grade level team through scaffolding techniques.
The IB keeps a learner profile that names the skills schools should build in learners at every IB grade. This can have a positive effect on school culture.
The IB Learner Profile aims to help learners become reflective individuals, risk-takers, thinkers, inquirers and principled learners. It also develops communicators who are knowledgeable, balanced, caring and open-minded. This includes critical thinking abilities and higher-order thinking skills.
The International Baccalaureate organisation states the main objective of all IB programmes and PYP. It is to "develop globally minded persons who, identifying their mutual humanity and shared control of the planet, help to build a more peaceful and better world." Many schools also aim to develop lifelong learners who contribute positively to society through stronger engagement strategies.
These concepts guide learner inquiry through strategic questioning techniques and help develop thinking skills. Teachers use thinking routines and metacognition strategies to support learners with sen as they explore these concepts in depth.
Each key concept serves as a lens through which learners can explore and understand their world more deeply. Form encourages learners to examine what things are like, their structure, properties, and characteristics. When studying water cycles, learners might investigate the molecular structure of water or observe cloud formations. Function focuses on how things work and their purpose, such as understanding how roots function to support plant life or how democratic systems operate in different countries. Causation develops critical thinking by examining why things happen and the relationships between actions and consequences. learners might explore what causes weather patterns or investigate the reasons behind historical events. Change helps learners recognise that everything is in a constant state of transformation, whether examining how communities evolve over time or observing metamorphosis in living organisms. Connection emphasises the relationships and links between different elements, encouraging learners to see how environments interconnect or how mathematical concepts relate to real-world problems. Perspective develops empathy and critical thinking by exploring different viewpoints and recognising that people may interpret the same situation differently. Responsibility focuses on our obligations and the consequences of our choices, both individually and collectively. Finally, Reflection encourages metacognitive thinking, helping learners consider their learning processes and evaluate their unders tanding.Plan carefully using PYP for these concepts to succeed. Teachers model thinking using concept language, helping learners identify concepts during lessons. When studying migration, ask, "What causes movement?" (causation) or "How do people view it?" (perspective). This strengthens understanding and inquiry (PYP).
Use concept walls; learners note discoveries and connections (Wiggins & McTighe, 2005). Reflection, like concept mapping, clarifies understanding across contexts (Novak, 1998). This helps learners think critically and transfer learning (Bransford et al., 2000).
Plan lessons to include PYP key concepts, integrating understanding. Do not isolate concepts; embed them into units. Learners explore form, function, and more, in real contexts. This fits constructivism (Bruner, 1966); learners build knowledge by connecting ideas.
Find key concepts in your unit's central idea. Then, design activities that let learners explore them. For example, with migration, examine causes and community changes. Consider diverse views on cultural integration. Hattie's (date) work shows making connections clear to learners helps. This allows learners to recognise patterns across subjects.
Concept walls help learners share understanding (Wiggins & McTighe, 2005). Use journals or portfolios to track how learners' ideas change. Documenting thinking supports reflection and assessment (Costa & Kallick, 2009). It also shows learning across subjects.
Assess learner understanding with evaluations, not just knowledge tests. Apply concepts across subjects, instead of rote facts (Wiggins & McTighe). Assessment should drive instruction, showing real comprehension. Use it as a starting point for professional discussion: identify the learner's current need, record evidence from more than one lesson, and agree the next classroom adjustment with the SENCO or family.
Authentic tasks help teachers evaluate conceptual understanding in the PYP. Learners could show 'causation' knowledge by analysing history or science. Portfolios track development over time. Peer discussions and journals show thinking. These methods give useful feedback (Wiggins, 1998).
Teachers need success criteria that focus on deep understanding. Develop rubrics which assess a learner's ability to connect ideas. Regular chats let learners explain concepts, aiding comprehension and thinking skills.
Bruner's spiral curriculum (1960) shows how repeated concepts help learners. Understanding deepens when they see ideas in varied contexts. An inquiry might explore change using science, connection using maths, and perspective using history. This builds rich conceptual links.
Transdisciplinary learning works best when teachers plan for linked concepts. Learners recognise patterns exploring function across subjects (Bransford et al., 2000). This builds thinking skills and aligns with cognitive research. Knowledge is more accessible in connected frameworks (Willingham, 2009).
Mapping conceptual pathways helps teachers link subjects. Find natural concept overlaps and design activities showing these connections. When learners see causation links science and history, flexible thinking grows (Wiggins and McTighe, 2005). This boosts inquiry-based learning (Costa and Kallick, 2008).
AI tools change how teachers use PYP Key Concepts, adapting to each learner's inquiry. Algorithms can analyse responses and create personalised prompts. Recent guidance from the Department for Education encourages the careful use of AI systems that aid learning, with teacher oversight.
Digital concept mapping platforms now use AI-generated prompts to guide learners through the seven PYP lenses systematically. When Year 5 learners investigate 'How We Express Ourselves', AI tools can suggest connection-based questions like "What patterns do you notice between traditional storytelling and modern social media?" whilst simultaneously tracking which concepts learners engage with most naturally. This algorithmic assessment provides teachers with real-time data about conceptual gaps without requiring extensive marking.
AI tools suggest lesson starters linked to Key Concepts. Teachers enter a unit topic, like 'Change' in science. The tool gives question banks to aid learner thinking. Some emerging research suggests AI frameworks may support concept transfer, though specific effect sizes remain difficult to verify.
AI tools can personalise learning. Pathways change with learner responses. This active approach challenges learners based on their own ideas. The method preserves inquiry, key to primary years learning.

The 7 key concepts are form, function, causation, change, connection, perspective, and responsibility. These serve as lenses for inquiry, helping learners look beyond facts to reach a deeper understanding of a topic. Each concept is framed by a key question, such as "What is it like?" for form or "How does it work?" for function.
Teachers use these concepts to plan units of inquiry that bridge different subject areas. In the classroom, this involves using specific questioning techniques and thinking routines to help learners explore a topic from multiple angles. For example, a teacher might ask learners to consider the perspective of different characters in a story or the causation behind a scientific reaction.
A concept driven approach helps learners make connections between different areas of knowledge; this prevents learning from becoming isolated into separate subjects. It encourages higher order thinking and helps children apply their understanding to new and unfamiliar situations. By focusing on big ideas, learners develop a more flexible and enduring grasp of the world around them.
Evidence suggests that inquiry based frameworks improve learner engagement. They also help learners build critical thinking skills. Research shows that metacognition and self regulation strategies are central to the PYP and have a high impact on progress. Studies also show that children remember more and develop stronger problem solving skills when they take an active role in learning.
One common error is treating the concepts as a checklist to be completed rather than as tools for deep exploration. Teachers sometimes provide the answers too quickly, which limits the opportunity for genuine learner inquiry. Another mistake is failing to revisit concepts across different themes, which prevents learners from seeing how the big ideas connect across the whole curriculum.
In the PYP, responsibility encourages learners to consider the consequences of their actions and the choices they make. It asks the question, "What is our responsibility?" in relation to the environment, the community and personal behaviour. This concept helps children develop a sense of agency and understand their role in creating a more peaceful world.
PYP implementation needs suitable activities. Early Years and Year 1 learners explore concepts like form through sensory play. They examine how shapes allow objects to roll or stack. This concrete experience aids later symbolic understanding.
Guided inquiry and shared tasks help Years 2-4 learners think in concepts. For example, plant growth experiments help learners see causation, (Piaget, 1954). Mapping local areas to global issues helps them see connections, (Vygotsky, 1978).
Scaffolding gives learners support as they link what they notice to more careful analysis. They can then show their understanding in many ways.
Years 5-6 learners can grasp complex ideas. They can use role-play to explore perspectives and think about responsibility in sustainability issues.
Sweller's cognitive load theory (date?) suggests that clear structure is vital. Use real-world problems as conceptual anchors, then help learners transfer understanding across subjects for transdisciplinary learning.

IB clarified their Primary Years Programme (PYP) concepts for inquiry learning. The "8 Key Concepts" are now Specified Concepts (IB). This change clarifies their base role. Additional Concepts, introduced alongside, deepen learner inquiries (IB).
PYP inquiry uses seven key concepts: form, function, causation, change, connection, perspective, and responsibility. These concepts let learners explore themes using a consistent framework. Teachers use them to create questions, helping learners gain knowledge (Wiggins & McTighe, 2005).
IB encourages you to use Additional Concepts to strengthen learning. Concepts such as 'systems' or 'patterns' help learners investigate subjects in a focused way. You can also use 'culture', 'identity', 'power', 'community', and 'sustainability'. (International Baccalaureate, 2018).
Additional Concepts give you greater unit planning flexibility. Teachers can tailor inquiries to local contexts or curriculum needs. Learners move from general to detailed knowledge in areas of study. For example, migration (an Additional Concept) supports 'change' (a Specified Concept), (Wiggins & McTighe, 2005).
Specified and Additional Concepts name the key ideas in learning plans. In a "Sharing the Planet" unit, "connection" helps learners see interdependence. "Sustainability" helps them examine environmental impact. With a graphic organiser, learners map how actions link to sustainability.
A teacher might prompt learners: "How does the form of a river influence its function, and what changes occur when human activity introduces a new system (Additional Concept) like a dam?" This approach helps learners build robust Mental Models, constructing internal representations that integrate both broad principles and specific details. Learners learn to articulate their understanding using precise vocabulary, supported by tools like writing scaffold that scaffold their conceptual explanations.
Teachers can design detailed inquiries by linking Specified and Additional Concepts. This helps learners understand ideas fully, going beyond simple facts. a structured thinking approach aids learners in breaking down complex ideas visually (Wiggins and McTighe, 2005). Colour-coded skill mapping can help analyse how concepts interact.
The International Baccalaureate Primary Years Programme (PYP) has introduced Inquiry Learning Progressions (ILPs) as a vital pedagogical tool. ILPs provide a framework for teachers to map the development of learners' inquiry skills and conceptual understanding over time. They illustrate how learners' ability to inquire, question, and explore deepens in sophistication as they engage with the PYP Key Concepts.
These progressions offer clear descriptors of what inquiry looks like at various stages of development, from early years to the end of the primary programme. Teachers can use ILPs to identify learners' current levels of inquiry expertise and plan targeted learning experiences. This ensures that teaching appropriately challenges learners to extend their conceptual understanding and inquiry capabilities.
ILPs are intrinsically linked to the PYP Key Concepts, demonstrating how learners' understanding of concepts like 'Causation' or 'Connection' becomes more careful. For instance, an ILP might show a progression from identifying simple cause-and-effect relationships to analysing complex, multi-faceted causal networks. This systematic approach helps learners build robust mental models of abstract ideas (Erickson, 2001).
Consider a Year 4 class exploring the Key Concept of 'Change' through a unit on local history. A teacher observes learners asking questions about why historical events occurred, noting their initial focus on single causes. Consulting the relevant ILP for 'Causation' (a related concept often intertwined with 'Change'), the teacher identifies that learners are at a stage where they can identify multiple causes but struggle with interconnectedness.
To support this progression, the teacher might introduce a graphic organiser, such as a multi-flow map (a type of concept maps), to help learners visually represent complex causal chains. Learners would then map out how various factors contributed to a historical event, such as the growth of their town. This visual tool helps learners articulate their evolving mental modelling of 'Change' and 'Causation', making their inquiry visible and assessable against the ILPs.
ILPs provide a common language for teachers to discuss and assess learner progress in inquiry and conceptual understanding. They clarify expectations for learning, allowing teachers to design units of inquiry that are appropriately scaffolded (Vygotsky, 1978). This ensures that learners are consistently challenged to develop more sophisticated ways of thinking and inquiring.
By explicitly mapping these progressions, teachers gain a deeper insight into how learners construct knowledge and develop inquiry skills. This clarity supports a consistent approach to teaching and learning across the school, ensuring learners build a strong foundation in conceptual understanding and inquiry. The ILPs ultimately guide learners towards becoming more independent, critical thinkers capable of deep, transferable learning.
The Enhanced PYP (2018) reframed Reflection as an Embedded Process, moving it from a standalone Key Concept to an integral element woven throughout all inquiry. This adjustment acknowledges that reflection is not a discrete stage but a continuous cycle of thinking about learning itself. Teachers must therefore integrate reflective practices into every phase of an inquiry, rather than treating it as a final activity.
An embedded process means learners reflect before, during, and after learning experiences. This reflection shapes their understanding and guides what they do next. Learners use metacognitive thinking, which means they think about what they already know, check their understanding, and review their strategies. This ongoing self-assessment helps them notice how they learn and how they build knowledge (Flavell, 1979).
This continuous engagement with reflection encourages learners to question their assumptions, adapt their approaches, and deepen their conceptual understanding. For instance, before starting a unit on 'Change', learners might reflect on personal experiences of change, activating prior knowledge and setting a purpose for inquiry. During the unit, they reflect on new information, adjusting their initial ideas.
A teacher might ask, "What do you already know about how plants grow, and what questions do you have?" This prompts initial reflection. Later, while observing plant growth, the teacher could ask, "What are you noticing that is different from your prediction? How does this new observation change your understanding of 'causation' in plant life?" This guides learners to reflect on evolving understanding.
classroom resources support reflection. Learners use tools like 'Compare and Contrast' maps to find similarities (Fisher, 2001). They then think about why they chose those criteria (Claxton, 1999). internal representations makes learners show their concept understanding, reflecting on knowledge gaps (Carr, 2000). writing scaffolds help learners pause and understand ideas (Winch, 2004).
Researchers suggest embedding reflection helps learners develop metacognitive habits. (Schon, 1983) This reflective practice is vital for transferable skills. (Dewey, 1933) It also encourages lifelong critical thinking and inquiry. (Moon, 1999; Boud et al., 1985)
The IB PYP curriculum planning shifted from linear documents to Subject Continuums. These continuums change how teachers plan learning, says research (IBO, various dates). They help track learner understanding, not just tick off content. Teachers can then support conceptual growth across subjects.
Unlike prescriptive lists, Subject Continuums illustrate how conceptual understanding develops over time and across different subjects. For instance, a continuum for 'Change' might show how a learner's understanding progresses from observing seasonal changes in early years science to analysing societal transformations in later years history. This approach allows teachers to identify where learners are in their learning process and plan experiences that build upon their existing knowledge, rather than simply moving through a predetermined sequence of topics (Wiggins & McTighe, 2005).
Teachers use Subject Continuums to map Key Concepts in subjects. For instance, planning Causation in Year 3, a teacher checks science. They see how learners understand cause and effect in experiments. They use social studies to see how learners identify causes in history (Erickson, 2002; Wiggins & McTighe, 2005). This shows subject links.
Our a structured thinking approach tools, such as Graphic Organisers and concept maps, can directly support teachers in visualising and tracking this conceptual progression. A teacher might use a Cause and Effect concept maps to assess a learner's understanding of Causation in a science experiment, then use a similar structure to explore the causes of a historical event, demonstrating growth along the respective Subject Continuums. This consistent application helps learners build robust mental models of concepts, making their learning transferable.
Subject Continuums help teachers assess learners' concept application. Instead of marking facts, teachers observe learners making connections. For example, a learner could explain story character viewpoints. They could then analyse global viewpoints using the same lens. This shows progression (Language, Social Studies), according to research by .
The Subject Continuums help learners build understanding, not just gather facts. Teachers should plan inquiries that challenge learners to review Key Concepts often. This boosts curiosity and critical thinking. This approach supports lifelong learning.
Within the Primary Years Programme (PYP), Lines of Inquiry serve as specific, focussed questions or statements that clarify the scope of a unit for learners. These lines break down the overarching Central Idea into manageable areas of investigation, guiding learners towards deeper understanding. The PYP Key Concepts are instrumental in framing and defining these lines, ensuring a conceptual foundation for each inquiry.
Each Line of Inquiry is deliberately constructed through the lens of one or more PYP Key Concepts, providing a distinct perspective for exploration. For instance, if a Central Idea is "Communities are shaped by their environments," a Line of Inquiry framed by Connection might ask, "How are human communities connected to their local environments?" This ensures learners investigate the relationships and interdependencies inherent in the topic.
Teachers can guide learners in developing these lines using visual tools like a structured thinking approach. A teacher might present the Central Idea and then ask learners, "Which Key Concept helps us think about why things happen?" Using a structured thinking approach’s colour-coded 'Causation' skill, learners could then formulate a Line of Inquiry such as, "What causes communities to adapt to environmental changes?" This process helps learners build mental models of the inquiry structure.
By explicitly linking Lines of Inquiry to specific Key Concepts, learners gain clarity on the intended learning outcomes and the conceptual focus of their investigations. This structured approach helps them move beyond surface-level facts, encouraging them to ask more profound questions and make meaningful connections. Learners develop a richer internal representation, or Mental Model, of the topic, understanding not just 'what' but 'why' and 'how'.
Consider a unit on "The choices we make have consequences." Different Key Concepts can generate varied, yet complementary, Lines of Inquiry. Responsibility might lead to "What are our responsibilities when making choices that affect others?", while Perspective could prompt "How do different viewpoints influence the choices people make?" This ensures a complex exploration of the Central Idea.
These conceptually framed Lines of Inquiry allow learners to take ownership of their learning, as they understand the conceptual lens guiding their research. They learn to identify the underlying concepts within any given topic, a skill transferable across all subjects. This systematic approach to inquiry builds deeper engagement and more coherent investigations, moving learners towards genuine conceptual understanding (Murdoch, 2015).
While the seven PYP Key Concepts provide broad lenses for inquiry, Related Concepts offer a necessary layer of disciplinary depth. These narrower, subject-specific concepts connect directly to the Key Concepts, allowing learners to explore ideas with greater precision within specific subjects like science, history, or mathematics.
Related Concepts act as a bridge, linking the overarching conceptual understandings to the specific content being studied. For example, while "Change" is a broad Key Concept, "adaptation" in biology, "revolution" in history, or "transformation" in mathematics are all specific Related Concepts that deepen understanding within those disciplines. This layering helps learners build more robust mental models of complex ideas, moving beyond superficial facts to grasp underlying principles.
Related Concepts keep inquiry academically strong and genuine. They give learners the words and concepts they need for focused investigations, not just basic exploring. This aligns with frameworks emphasising lasting knowledge (Wiggins & McTighe, 2005). Learners also develop transferable skills.
Consider a unit exploring the Key Concept of "Change" in science. Instead of simply observing changes, the teacher introduces the Related Concept of "adaptation". Learners might then investigate how different organisms *adapt* to their environments, using a Graphic Organiser to compare structural and behavioural adaptations. This helps them articulate specific examples of change within a biological context.
Similarly, in a history unit focusing on the Key Concept of "Connection", a teacher could introduce the Related Concept of "conflict". Learners would then analyse historical events not just as isolated incidents, but as interconnected sequences driven by *conflict*, exploring its causes, manifestations, and resolutions. They might use a concept maps, such as a Multi-Flow Map, to visualise the intricate causes and effects of a specific historical conflict.
Teachers use Related Concepts to formulate more precise inquiry questions and design focussed learning experiences. For instance, a question might shift from "How do things change?" to "How do organisms *adapt* to environmental changes?" structured thinking approaches can support learners in visually deconstructing these specific concepts, using colour-coded skills to identify and analyse their components within a given context.
Explicitly teach Related Concepts so learners build strong disciplinary knowledge. Learners then think like experts, using concepts to analyse information (Erickson, 2002). This approach builds inquiry skills and readies them for harder tasks (Wiggins & McTighe, 2005). Learners appreciate knowledge's interconnectedness (Bruner, 1960).
The Central Idea functions as the overarching conceptual statement that frames each transdisciplinary unit of inquiry within the Primary Years Programme (PYP). It is a concise, enduring understanding that learners will explore and construct meaning from throughout the unit. This statement acts as the primary conceptual lens, guiding both teacher planning and learner investigation towards deeper understanding rather than mere factual recall.
A well-crafted Central Idea is conceptual, transferable, and significant, ensuring that learning extends beyond specific content to broader understandings. It provides a clear focus for inquiry, prompting learners to ask conceptual questions and make connections across different subject areas. For instance, a Central Idea like "Human migration is a response to challenges and opportunities" encourages exploration of causation, change, and perspective.
The PYP Key Concepts directly support the exploration of the Central Idea by providing specific conceptual lenses through which learners can investigate. While the Central Idea sets the broad conceptual destination, the Key Concepts offer the pathways for inquiry. Teachers use these concepts to examine the Central Idea, designing learning experiences that prompt learners to consider 'Form', 'Function', 'Causation', or 'Change' in relation to the unit's core understanding.
Consider a unit with the Central Idea: "People express themselves in diverse ways to communicate and connect." A Year 4 teacher might introduce this by asking, "How do we show who we are without words?" and "What makes a message clear or unclear?" This prompts learners to think about the 'Form' of expression (e.g., dance, art, music) and its 'Function' in communication.
Learners then engage in inquiries, perhaps researching different cultural dances or creating visual art to convey an emotion. They might discuss how a specific dance 'changes' its meaning depending on context, or reflect on the 'perspective' of the artist or audience. This process helps learners build a rich mental model of how expression works, moving beyond simply identifying different art forms (Erickson, 2001).
The Central Idea helps assess learner understanding. Teachers check if learners can explain and use core concepts, not just remember facts. This makes learning transferable (Wiggins & McTighe, 2005). Learners can apply understanding to new situations, like analysing ads (Kellner & Share, 2007). They can also understand social cues (Hall, 1966).
The distinction between factual and conceptual knowledge is fundamental for effective inquiry-based learning. While facts provide needed building blocks, conceptual understanding moves learners beyond superficial recall to grasp enduring ideas. This shift enables learners to apply their learning across diverse contexts.
Factual knowledge consists of specific, discrete pieces of information, typically bound by time and place. It answers questions like "what," "who," "when," and "where." Examples include specific historical dates or the names of animal classifications.
Learners develop conceptual knowledge using transferable ideas (Anderson & Krathwohl, 2001). This lets learners see patterns and connections across situations. Instead of only memorising, they understand causes and effects of "change".
Focusing only on facts restricts how learners connect ideas. Conceptual frameworks help learners apply knowledge in different situations (Erickson, 2001). They create mental models, boosting deep learning and knowledge transfer.
Consider a science lesson on environments. A factual approach names specific plants and animals in a pond. A conceptual approach guides learners to explore "interdependence," examining how organisms rely on each other for survival, regardless of the specific environment.
Teachers guide learners to ask "why" and "how," beyond just "what." Graphic organisers help learners visualise links (Marzano et al., 2000; Hyerle, 2009). Cause-and-effect tools map connections between events (Fisher, 2008).
Researchers (Bransford et al., 2000) show conceptual knowledge helps learners synthesise information. Learners also identify patterns and build their own meaning. This prepares them for complex real-world problems, (Wiggins & McTighe, 2005). Flexible thinking and adaptable understanding are vital, as noted by researchers (Darling-Hammond et al., 2020).
Researchers (no name/date given) say provocations spark learner curiosity. These stimuli begin inquiry, moving learners beyond simple observation. Learners investigate, question, and connect ideas using these starters. This directly addresses PYP Key Concepts.
Effective provocations can take many forms, each designed to challenge assumptions and encourage conceptual thinking. For instance, a teacher might display an unusual artifact, such as an antique map or a broken machine, without explanation. Learners then engage in immediate questioning about its form, function, and potential causation, prompting a genuine need to investigate further.
Changing the physical learning space also serves as a powerful provocation. A teacher could transform the classroom into a simulated archaeological dig site or a miniature environment, complete with relevant materials and tools. This environmental shift encourages learners to consider the connection between elements and the change that might occur within such a system, building an immersive inquiry experience.
Posing wonderings or open-ended questions directly stimulates conceptual thinking. A teacher might ask, "What if gravity suddenly stopped working?" or "How does our individual perspective shape our understanding of fairness?" Such questions compel learners to consider abstract ideas and explore potential consequences, driving inquiry into core concepts like change, causation, and responsibility (Murdoch, 2015).
For example, to explore the concept of change, a teacher could present learners with a series of photographs depicting the same local landmark across several decades. Learners observe the visual evidence, discuss what has altered, and hypothesise the reasons for these transformations, leading to an investigation into the forces driving societal and environmental shifts.
These varied provocations serve as entry points for learners to engage with the PYP Key Concepts, moving from initial curiosity to structured inquiry. By carefully crafting these starting points, teachers guide learners to ask conceptual questions, build mental models of complex ideas, and develop a profound understanding that extends across disciplines.
The PYP Key Concepts are instrumental in cultivating strong learner agency, enabling learners to take ownership of their learning process. When learners engage with concepts like Causation or Change, they move beyond passively receiving information to actively constructing understanding. This process naturally provides opportunities for learners to exercise their voice and make meaningful choices about their learning path.
Conceptual inquiry directly strengthens learners' self-efficacy, which is their belief in their own capability to succeed in specific tasks (Bandura, 1977). As learners grapple with complex ideas and make connections across disciplines, they develop a robust sense of intellectual competence. They perceive themselves as capable thinkers who can formulate questions, investigate, and construct knowledge, rather than simply recall facts.
For instance, in a unit exploring "Human Impact on Environments," a teacher might pose, "How does human activity cause changes in local environments, and what is our responsibility?" Learners then exercise agency by choosing a specific local environment to investigate, deciding on their research methods, and determining how to present their findings. They might use a Graphic Organiser to map out the connections between human actions and environmental changes, demonstrating their choice in tools and approach.
This active engagement, driven by conceptual understanding, allows learners to develop their unique perspectives and contribute meaningfully to classroom discourse. When learners are encouraged to explore the Perspective concept, they learn to value diverse viewpoints, including their own. This builds a classroom culture where their voice is heard and respected, further building their confidence and sense of agency.
PYP helps learners build self-efficacy through Responsibility and Reflection. Self-efficacy means belief in their ability to learn. Learners assess what they understand and adapt their strategies to manage their learning. This metacognitive work, using internal representations, strengthens their belief in their learning abilities (Bandura, 1977).
Visible Thinking Routines are structured protocols designed to make learners' thought processes explicit and observable. These routines encourage learners to articulate their understanding, question assumptions, and connect new information to prior knowledge (Ritchhart et al., 2011). By making thinking visible, teachers can better assess conceptual understanding and guide learners towards deeper inquiry.
To explore PYP Key Concepts effectively, teachers can integrate specific Visible Thinking Routines. For instance, Harvard Project Zero's "See, Think, Wonder" routine prompts learners to observe, interpret, and inquire about a stimulus, directly supporting investigation into concepts like Form or Change. Another effective routine is "Sketch the Concept," where learners visually represent their understanding of a key concept, such as Connection or Causation, often using a graphic organiser.
Consider a Year 4 class investigating the PYP Key Concept of Change in a science unit on life cycles. The teacher might use a "Bus Stop" activity: learners move between stations, each posing a different question about change in a butterfly's life cycle. At each station, they record their thoughts using a simple writing frame or a section of a structured thinking approaches tool, discussing how the butterfly's form changes and the causation behind these transformations. This activity makes their evolving understanding of change visible and allows for peer interaction.
Kath Murdoch's Inquiry Cycle provides a robust framework for guiding learner investigations, and the PYP Key Concepts offer the needed intellectual depth for each phase. These conceptual lenses ensure learners move beyond surface-level questions to explore underlying principles and enduring understandings (Murdoch, 2015). For example, during the 'Tuning In' phase, learners might use the concept of 'Form' to observe and describe the physical characteristics of a new material, or 'Function' to consider its purpose.
Learners explore relationships, asking "What causes this weather pattern?" (Finding Out, Sorting Out). 'Connection' links ideas across subjects like history and social structures (Going Further, Taking Action). 'Responsibility' guides ethical thinking and action. Teachers ask, "How does biodiversity change connect to our global responsibility?", promoting deeper understanding.
Building on this, Lynn Erickson's foundational work defines concepts as broad, abstract, timeless, and universal mental constructs (Erickson, 2007). These enduring ideas transcend specific facts or topics, providing a framework for learners to organise vast amounts of information. For instance, the concept of 'change' is not merely a historical event but a universal process observed in science, art, and human societies.
Erickson argues that a curriculum built around such concepts becomes 'three-dimensional', moving beyond the two dimensions of facts and skills to include deeper conceptual understanding. This approach ensures learners develop robust mental models, allowing them to see connections and apply learning flexibly across disciplines. A teacher might ask learners, "How does the concept of causation help us understand why the river flooded?" prompting them to consider universal principles rather than just local facts.
Concept-Based Inquiry provides a robust framework for learners to explore the PYP Key Concepts, moving beyond facts to enduring understandings. This approach, central to the IB Primary Years Programme, guides learners to formulate and investigate conceptual questions, building deeper engagement (Erickson, 2001).
IB guidance helps teachers link concepts to key questions and examples. Teachers plan activities using concepts as lenses for investigation (IBO, 2024). This is backed by inquiry questions.
For example, exploring 'Change' in a history unit, a teacher might ask, "How did significant changes in leadership or environment shape ancient societies?" Learners investigate primary sources, identifying patterns of cause and effect in human development.
Learners gain knowledge they can transfer between subjects. The method encourages critical thought. Learners connect their learning across different contexts (Bransford et al., 2000), not just learn facts (Willingham, 2009; Bjork & Bjork, 2011).
IB's Approaches to Learning help learners become self-regulated inquirers. The five skills are communication, social, self-management, research, and thinking (IBO, 2018). Teachers directly instruct these skills, using specific indicators to guide learners.
Learners ask questions, gather information, and bring ideas together (Biggs & Tang, 2011). Instead of setting broad research tasks, ask them to connect different viewpoints on deforestation.
Thinking skills include creating ideas and designing solutions. For example, set the challenge: "Design a recycled playground", so learners practise problem-solving and explore concepts in depth (Willingham, 2009).
The International Baccalaureate (IB) has refined its terminology for the PYP key concepts. It has moved beyond the simple "8 Key Concepts" designation. This update gives teachers more clarity and flexibility when they design inquiry-based learning experiences. It also sets a clearer distinction between universally applicable concepts and concepts that give a specific focus within a unit.
The seven concepts; form, function, causation, change, connection, perspective, and responsibility; are now formally known as Specified Concepts. They remain central to PYP inquiry. They act as broad, transdisciplinary lenses that help learners explore the world. They also give teachers and learners a shared conceptual language for understanding phenomena across all subject areas (IBO, 2018).
Teachers utilise these Specified Concepts to frame needed questions and guide learners towards deeper understanding, moving beyond surface-level facts. For example, when exploring a natural phenomenon, a teacher might ask, "What is its form and how does it function?" or "What causes it, and how does it change over time?" This approach helps learners identify underlying patterns and relationships (Erickson, Lanning & French, 2017).
To complement the Specified Concepts, the IB introduced Additional Concepts. These concepts allow for more careful inquiry that fits the context of a unit. Additional Concepts can come from subject-specific disciplines, such as democracy in social studies or energy in science. They can also be developed locally to address particular community or curriculum needs.
Additional Concepts offer teachers the flexibility to refine the scope of an inquiry, making it more relevant and engaging for learners. They help bridge the gap between broad transdisciplinary themes and specific subject content. For instance, while "change" is a Specified Concept, an Additional Concept like "adaptation" could provide a more precise lens when studying how organisms respond to environmental shifts.
When planning a unit of inquiry, teachers select relevant Specified Concepts as overarching conceptual lenses. They then identify Additional Concepts that will further deepen understanding within the unit's specific context. This layered approach ensures that inquiry remains both broad in its conceptual scope and focused in its disciplinary application.
Consider a Year 4 unit on "Sharing the Planet" focusing on sustainable practices. The teacher might select responsibility and connection as Specified Concepts. To add depth, they could introduce Additional Concepts such as consumption (from economics) and conservation (from environmental science). learners might then investigate: "What is our responsibility to the environment (responsibility), and how are human actions connected to environmental impact (connection)?" and "How does our rate of consumption affect resources, and what conservation strategies can we implement?" This demonstrates how both types of concepts structure a comprehensive inquiry.
This updated terminology makes the hierarchy of concepts within the PYP framework clearer. It helps teachers design inquiries that are coherent and rigorous. It also supports learners to build broad conceptual understandings and specific knowledge within different disciplines. This distinction helps teachers explain learning goals more clearly to learners and parents, improving overall programme clarity.
The Primary Years Programme (PYP) has introduced Inquiry Learning Progressions (ILPs). These progressions give teachers a clear way to see how inquiry skills and conceptual understanding grow over time. Teachers use ILPs to track how learners' thinking and action become more developed during inquiry-based learning (IBO, 2019).
ILPs are designed as continua that describe observable behaviours and understandings across different phases of learning. They outline what inquiry looks like as learners move from initial engagement to deeper investigation, synthesis, and reflection. This allows educators to identify where individual learners are in their inquiry development and plan appropriate next steps.
For example, an ILP for the skill of 'researching' might begin with learners identifying simple facts from a provided text. It would then progress to learners formulating their own research questions, selecting credible sources, and synthesising information from multiple texts. Teachers can observe these behaviours and use the ILP to guide their feedback and instructional choices.
The PYP key concepts are intrinsically linked with ILPs, as conceptual understanding deepens alongside inquiry skills. As learners progress through an ILP, their ability to apply the key concepts; such as causation or connection; becomes more careful and sophisticated. This integration ensures that inquiry is not just about finding answers, but about constructing deeper meaning.
Consider a unit exploring the key concept of change. An early years learner, at an initial stage of an ILP, might simply observe and describe seasonal changes in their local environment. The teacher might prompt, "What do you notice is different about the trees today compared to last month?" A primary learner, at a more advanced ILP stage, might investigate historical changes in a community, analysing the factors that led to those changes and predicting future impacts. The teacher would guide them to ask, "What caused these changes, and what were the effects on people's lives?"
ILPs are useful tools for formative assessment because they help teachers track how learners grow through inquiry. When teachers check the progressions often, they can see where learners need more support or more challenge. This supports targeted differentiation. As a result, all learners can take part in inquiry in a meaningful way and at the right developmental level (Wiliam, 2011).
Ultimately, the aim of ILPs is to cultivate independent, self-regulated learners who can transfer their inquiry skills and conceptual understandings across new contexts. They provide a common language for teachers to discuss learner progress and ensure a coherent approach to inquiry-based teaching throughout the school. This structured approach helps learners not only to learn content but also to learn how to learn effectively.
While earlier iterations of the Primary Years Programme (PYP) listed 'Reflection' as one of the eight key concepts, the Enhanced PYP (2018) formally repositioned it. Reflection is now understood not as a standalone conceptual lens, but as an overarching, embedded process integral to every stage of inquiry. This shift recognises reflection's foundational role in developing deep understanding and self-regulated learners.
Reflection involves learners actively thinking about their learning experiences, strategies, and outcomes. It moves beyond simply recalling facts to critically examining how knowledge is constructed, what challenges were faced, and how understanding has evolved. This metacognitive process is necessary for learners to become aware of their own thinking and learning habits (Dunlosky et al., 2013).
As an embedded process, reflection occurs continuously throughout the inquiry cycle, not just at its conclusion. Learners engage in reflective practices when they activate prior knowledge, monitor their understanding during investigations, and evaluate the effectiveness of their chosen learning strategies. This ongoing self-assessment helps learners adjust their approach and deepen their engagement with the subject matter.
Teachers facilitate reflection by posing targeted questions that prompt learners to consider their learning. For example, before starting a new unit, a teacher might ask, "What do you already know about this topic, and what questions do you have?" This encourages learners to connect new learning to existing schemas and identify areas for exploration.
During an inquiry, learners might be asked to pause and consider, "What strategies are you using to find information, and are they effective?" or "How is your understanding changing as you investigate?" A learner might then realise their initial research method is too slow and decide to try a different approach, such as interviewing an expert or using a different search engine.
After completing a task, reflection helps learners consolidate learning and plan next steps. A teacher might ask, "What did you learn about working with your group, and what would you do differently next time?" or "How does this new understanding connect to something we learned last term?" Learners could record their thoughts in a learning journal or discuss them with a peer, identifying areas for further growth.
This continuous reflective practice helps learners develop agency over their learning, building a sense of ownership and responsibility. By regularly reflecting on their processes and products, learners learn to identify their strengths, recognise areas for improvement, and transfer their learning strategies to new contexts. This cultivates the critical thinking and self-regulation needed for lifelong learning (Dewey, 1933).
The International Baccalaureate Primary Years Programme (PYP) has moved beyond traditional, linear 'Scope and Sequence' documents, adopting a more fluid approach through 'Subject Continuums'. These continuums articulate how learning deepens and broadens across the age range, rather than simply listing content to be covered year by year. They provide a framework for teachers to understand the progression of conceptual understanding and skill development within each subject area.
Subject Continuums show how conceptual growth builds across different disciplines. They give teachers a clear view of learner development. In 'Science', for instance, a continuum might show two stages: early learners notice simple cause-effect observations, while older learners analyse complex multi-variable systems. This helps teachers identify learners' current level of conceptual development and plan instruction accordingly (IBO, 2018).
Consider a Year 2 teacher exploring the PYP Key Concept of Causation in a science unit on plant growth. The Subject Continuum for Science might indicate that learners at this stage should be able to identify simple causes for observable effects, such as 'lack of water causes a plant to wilt'. Later, a Year 5 teacher, guided by the same continuum, would expect learners to investigate multiple factors influencing plant growth, perhaps designing experiments to test the effect of light intensity or soil nutrients on plant health.
The teacher uses the continuum not as a rigid checklist, but as a guide to pose increasingly complex questions and design appropriate inquiries. For the Year 2 class, the teacher might ask, 'What caused the leaves to turn yellow?' prompting learners to consider factors like sunlight or water. In Year 5, the question might evolve to, 'How do different environmental factors interact to cause variations in plant growth across different networks?' encouraging deeper investigation and synthesis of knowledge.
This conceptual progression is set out through Subject Continuums. It helps learners transfer understanding across different subjects. For example, Causation is not only a science concept. It also applies to history (causes of events), mathematics (cause-effect in patterns), and language arts (character motivations).
Teachers can make these links clear. This helps learners see how knowledge connects and apply conceptual understanding in different contexts (Erickson, Lanning & French, 2017).
When teachers understand the expected path of conceptual development, they can plan units of inquiry that build on prior learning. Assessment then moves beyond checking factual recall. It also looks at how well learners apply and explain their conceptual understanding at different levels. This helps keep learning challenging and supports real intellectual growth.
Lines of Inquiry are necessary statements within a PYP unit of inquiry, serving to clarify the specific scope of investigation for learners. They break down the central idea of a unit into manageable, focused questions or statements that guide learner exploration. These lines ensure that learners understand the particular aspects they are expected to investigate, preventing unfocused or superficial learning.
The PYP Key Concepts directly frame and define these Lines of Inquiry, transforming them from simple topics into conceptual explorations. Instead of merely asking "What happened?", a key concept encourages questions like "What caused this to happen?" or "How has this changed over time?". This conceptual lens helps learners move beyond surface-level facts to discover deeper understandings and relationships (Erickson, Lanning & French, 2017).
Teachers explicitly integrate key concepts when formulating Lines of Inquiry to provide a clear conceptual direction for the unit. For instance, a line of inquiry might be phrased to explore the "form" of different energy sources, or the "connection" between human actions and environmental impact. This intentional linking ensures that each inquiry strand contributes to a broader conceptual understanding, rather than isolated knowledge acquisition.
Consider a unit with the central idea "Human actions impact the environment." A teacher might develop a Line of Inquiry such as: "How do our daily choices cause environmental change?" Here, 'causation' and 'change' are the guiding key concepts. Learners would then investigate specific daily choices, like waste disposal or transportation, to identify their direct effects on local networks, documenting the cause-and-effect relationships they observe.
Another example could use the Line of Inquiry: "How do different cultures develop unique perspectives on community?" This asks learners to research different cultural practices and beliefs. They learn that societies understand and organise community life in different ways. By focusing on 'perspective', learners learn to value diversity and question their own ideas about social structures.
By using key concepts to define Lines of Inquiry, teachers provide learners with powerful tools for structuring their investigations. This approach helps learners to organise new information, identify patterns, and make meaningful connections across different areas of knowledge (IBO, 2018). Consequently, learners develop a more profound and transferable understanding of the world around them.
Careful use of PYP Key Concepts within Lines of Inquiry makes learning purposeful and rich in concepts. It moves learners beyond simply gaining information. Instead, they build knowledge through critical thinking and inquiry. This planned approach helps them become independent, lifelong learners who can apply their understanding in new contexts.
Beyond the seven broad PYP Key Concepts, the framework also incorporates Related Concepts, which provide a necessary layer of subject-specific understanding. These narrower, disciplinary concepts allow learners to explore topics with greater precision and depth within particular learning areas. While Key Concepts offer overarching lenses for inquiry, Related Concepts help to define the specific focus of that inquiry within a subject.
Related Concepts act as bridges, connecting the expansive scope of the Key Concepts to the detailed content of individual disciplines. They ensure that inquiry-based learning is not only conceptually rich but also grounded in specific subject knowledge. For instance, while 'change' is a broad Key Concept, 'adaptation' in biology or 'revolution' in history are Related Concepts that specify the nature of that change within a particular field.
Examples of Related Concepts include 'structure', 'system', 'pattern', 'evidence', 'causality', 'power', 'conflict', 'sustainability', and 'perspective' (IBO, 2018). Teachers choose these concepts to match the learning objectives of specific subjects. They help learners organise complex information and make sense of it. They also guide learners to ask more focused questions and understand disciplinary methodologies, or the ways each subject builds knowledge.
Teachers integrate Related Concepts into unit planning by selecting those most relevant to the central idea and lines of inquiry. This intentional selection helps to frame the learning, providing learners with specific conceptual tools to analyse and synthesise information. For example, when exploring the Key Concept of connection, a science unit might focus on the Related Concept of interdependence within an network.
Consider a Year 4 unit exploring the Key Concept of change. A teacher might introduce the Related Concept of adaptation in science. Learners could investigate how different organisms *adapt* to environmental *changes*, examining the *form* and *function* of their physical characteristics. They might then consider how these adaptations demonstrate the *connection* between living things and their habitats.
This layered approach combines Key and Related Concepts. It helps learners transfer understanding across contexts. It also moves them beyond memorising separate facts, so they can build a clear conceptual framework for knowledge (Erickson, Lanning & French, 2017). Learners then apply specific disciplinary ideas to new situations and build genuine conceptual understanding.
Ultimately, Related Concepts give PYP inquiry the disciplinary depth it needs to be rigorous and meaningful. They give learners a vocabulary of powerful ideas. This helps learners explain their understanding with greater clarity and precision within and across subjects. This conceptual fluency is vital for developing sophisticated thinkers.
The Central Idea is the overarching statement that defines the scope and purpose of a transdisciplinary unit of inquiry. It functions as the primary conceptual lens, framing all learning experiences within the unit. This concise, enduring understanding expresses a significant idea that learners will explore through various subject areas, moving beyond isolated facts to interconnected knowledge (IBO, 2018).
This central idea is deliberately broad and timeless, encouraging learners to transfer their understanding across different contexts and disciplines. It provides the needed conceptual framework, ensuring that inquiry moves beyond factual recall to deeper conceptual understanding. The PYP key concepts then serve as specific questioning tools to explain and explore the nuances of this central idea, providing multiple entry points for investigation.
Teachers shape the central idea with care, so it is engaging, relevant, and challenging for learners. For instance, a central idea might be: "Human migration is a response to challenges and opportunities." This gives the unit a clear conceptual focus beyond one historical event or place. It invites learners to explore shared human experiences and build critical thinking.
Learners use the central idea as a guiding principle throughout their inquiry, constantly referring back to it to connect new information. When exploring the central idea "Human migration is a response to challenges and opportunities," learners might investigate how the key concept of causation explains why people move, or how change impacts both migrants and host communities. They might produce a graphic organiser mapping push and pull factors, or write a reflective piece on the perspective of a refugee, all while linking back to the core idea.
The central idea ensures that learning remains conceptually focused, preventing units from becoming mere collections of disconnected facts. It prompts learners to ask "So what?" and "Why does this matter?" continually, pushing them towards deeper meaning-making and the construction of personal relevance. This approach aligns with concept-based instruction, where understanding is built around big ideas rather than isolated topics, promoting transfer of learning (Erickson, Lanning & French, 2017).
By consistently returning to the central idea, teachers help learners build a coherent understanding of complex issues. This sustained engagement with a core concept helps learners develop transferable thinking skills, enabling them to apply their learning to new situations and challenges. The central idea thus serves as the anchor for all inquiry, building intellectual curiosity and critical thought that extends beyond the classroom.
Factual knowledge consists of specific, discrete pieces of information tied to a particular time, place, or context. It answers "what" questions, such as "What is the capital of France?" or "When did World War II begin?". While needed for foundational understanding, factual knowledge alone often leads to superficial recall and offers limited transferability to new situations.
In contrast, conceptual knowledge means broad, abstract ideas that go beyond one example or setting. Concepts are timeless and transferable. This helps learners make connections and use their understanding across subjects and real-world situations (Erickson, Lanning & French, 2017). Concepts answer "why" and "how" questions by showing the patterns and relationships that support deeper understanding.
The PYP key concepts help learners move beyond collecting facts. They guide learners to see the deeper conceptual relationships that shape those facts. For example, knowing specific historical dates is factual knowledge. Understanding causation helps learners analyse why events happened and how they led to later developments, a transferable skill for any inquiry.
Consider a unit on weather. A factual approach involves memorising cloud types or average rainfall in a specific city. A conceptual approach, using the key concept of change, prompts learners to investigate "How does weather change and what causes these changes?". Learners observe daily patterns, record data, and discuss underlying principles like atmospheric pressure, applying this understanding to predict future weather.
Teachers use purposeful questioning to guide learners from factual observations to conceptual generalisations. For example, learners might first list features of different animal habitats. The teacher might then ask, "What is the connection between an animal's physical characteristics and its environment?". This prompts learners to identify the concept of adaptation, a transferable idea that applies to various organisms.
Conceptual knowledge gives learners mental tools for an ever-changing world. When learners understand concepts like form, function, or perspective, they can interpret new information. They can also solve unfamiliar problems and construct meaning independently. This deeper understanding goes beyond rote learning, builds real intellectual curiosity, and prepares them for complex challenges.
Teachers design provocations to start inquiry and prompt conceptual thinking in learners. These carefully planned experiences are not direct instructions. Instead, they invite learners to investigate, question, and explore. A strong provocation sparks curiosity and helps learners look beyond surface-level observations, so they engage with the PYP key concepts from the start (Erickson, Lanning & French, 2017).
One effective approach involves using intriguing artifacts. A teacher might place an antique compass, a faded map, and a collection of old postcards on a table, asking learners, "What is the form of these objects? What might their function have been, and how do they connect?" Similarly, altering the physical learning space can serve as a powerful provocation. Rearranging classroom furniture to create a 'forest' area with natural materials encourages learners to consider the connection between living things and their environment.
Wonderings and challenging statements can also make strong provocations. For example, a teacher could start a unit by saying, "Sometimes, things that seem broken actually work better," and invite learners to question the function of objects or systems. A surprising statistic about global water usage could also prompt learners to consider their responsibility. It may also help them think about the causation of environmental issues.
After presenting a provocation, the teacher observes learners' initial reactions, listens to their questions, and facilitates discussion. This initial exploration helps to identify learners' prior knowledge and misconceptions, allowing the teacher to guide them towards deeper inquiry using the specific lenses of the PYP key concepts. The goal is to move learners from initial wonder to sustained, concept-driven investigation.
Conceptual learning, facilitated by the PYP Key Concepts, significantly strengthens learner agency. When learners engage with profound ideas like causation or connection, they move beyond passive reception of facts to actively construct their own understanding. This process naturally cultivates their voice, choice, and ownership over their learning experiences, as they are encouraged to explore concepts from their unique perspectives.
The inquiry-based nature of the PYP framework, driven by these key concepts, provides multiple avenues for learners to exercise agency. For example, when investigating the concept of change, learners might choose specific historical events or scientific phenomena to research, deciding on the methods for their inquiry and the format for presenting their findings. This autonomy is necessary for developing a sense of ownership.
Furthermore, conceptual understanding directly impacts self-efficacy, which is a learner's belief in their capacity to succeed in specific situations (Bandura, 1997). When learners are enabled to ask their own questions, pursue their own lines of inquiry, and make meaningful connections, they experience success in navigating complex ideas. This builds confidence in their intellectual capabilities.
Consider a Year 4 class exploring the key concept of responsibility. Instead of merely being told about responsibilities, learners might be asked, "What responsibilities do we have towards our local environment?" They could then choose to investigate littering, water conservation, or local wildlife, deciding how to gather information and propose solutions. This active engagement, coupled with the freedom to choose, reinforces their belief that their actions and ideas can make a difference.
Teachers help learners recognise their intellectual competence by giving them regular chances to apply concepts to real-world issues. Learners also express their individual interpretations. Over time, making choices and taking ownership builds a strong sense of agency. Guided by the PYP Key Concepts, this practice strengthens learners' belief that they can learn and contribute meaningfully.
Visible Thinking Routines are planned ways to make learners' thinking clear and easy to see. They give learners clear steps for inquiry and reflection, which helps them engage more deeply with PYP Key Concepts (Ritchhart, Church & Morrison, 2011). When learners show their thinking, they can explain complex ideas more clearly. Teachers can also spot misconceptions more easily.
For instance, when exploring the concept of Perspective, teachers might use the "Step Inside" routine, asking learners to imagine being a character or object and describing its thoughts and feelings. To investigate Causation, the "What Makes You Say That?" routine prompts learners to provide evidence and reasoning for their claims, such as "I think the flood was caused by heavy rain because the news report showed continuous downpours." These routines move beyond simple recall, building analytical skills.
Other specific routines include "Connect, Extend, Challenge," which helps learners link new information to prior knowledge. It also helps them spot areas of difficulty. "Sketch the concept" asks learners to show their understanding of a key concept visually, such as drawing the Connection between two historical events. A "Bus stop" activity lets small groups discuss different facets of a concept, then rotate to add to others' ideas and build collective understanding.
Displaying the outputs from these activities on a concept wall makes the class's growing understanding easy to see and use during a unit of inquiry. This ongoing record gives learners a strong reference point. It keeps key concepts in view and prompts further questions.
Kath Murdoch's inquiry cycle provides a structured approach for learners to explore conceptual understanding, moving beyond factual recall (Murdoch, 2015). Integrating the PYP key concepts within each phase deepens learner engagement and promotes transferable learning. Teachers guide learners to use these conceptual lenses throughout their investigations.
During the 'Tuning In' phase, teachers might prompt learners with questions about Form ("What does it look like?") or Connection ("What do you already know about this topic?"). As learners 'Finding Out', they apply Causation ("What made this happen?") or Function ("What is its purpose?") to gather information. For example, a Year 4 class investigating weather patterns might ask, "What is the form of a cloud?" then "What causes rain?"
In the 'Sorting Out' phase, learners consider Connection ("How do these ideas link?") or Perspective ("How do different cultures view this phenomenon?"). Later, 'Taking Action' naturally involves Responsibility ("What can we do to address this issue?"), while the final 'Reflection' phase directly uses the Reflection concept ("How has my understanding changed?"). This ensures a consistent conceptual thread throughout the entire inquiry.
Lynn Erickson's foundational work in concept-based curriculum highlights that true understanding stems from grasping ideas that are "broad, abstract, timeless, and universal" (Erickson, Lanning & French, 2017). These are not mere facts or topics, but enduring understandings that apply across disciplines and contexts. The PYP key concepts, such as form, causation, and connection, exemplify these characteristics, guiding learners to look beyond surface-level information.
This conceptual lens allows teachers to construct a "three-dimensional curriculum" where factual knowledge, conceptual understanding, and transferable skills are integrated. For instance, when studying historical events, a teacher might prompt learners to consider the causation of a conflict, the different perspectives involved, and the subsequent change it brought about. This approach ensures learners develop deeper comprehension and the ability to apply their learning in new situations.
Concept-Based Inquiry moves learning beyond factual recall. Learners explore enduring ideas that go beyond one topic. They investigate broad, transferable concepts and build deeper understanding and critical thinking. Teachers design learning experiences where learners actively construct knowledge by exploring conceptual questions.
The PYP Key Concepts are instrumental in facilitating Concept-Based Inquiry, acting as powerful lenses for investigation. The International Baccalaureate (IBO, 2018) provides pedagogical scaffolding, demonstrating how each key concept can generate specific inquiry questions. For instance, the concept of 'causation' prompts questions like, "Why did this happen?" or "What are the consequences of this action?"
Consider a science lesson on plant growth. A teacher might introduce the 'change' concept, prompting learners to inquire, "How do plants transform over time?" or "What factors cause these changes?" This helps learners analyse processes and apply conceptual understanding across different scientific phenomena (Erickson, Lanning & French, 2017).
The Approaches to Learning (ATL) are fundamental to inquiry-based teaching, equipping learners with needed skills for lifelong learning (IBO, 2018). These skills are not taught in isolation but integrated across all subjects, helping learners to learn how to learn effectively.
ATL covers five broad areas: Thinking, Research, Communication, Social, and Self-management skills. Each area includes smaller skill clusters. For example, Thinking Skills include critical analysis, creating new ideas, and bringing new understandings together. Research Skills include information literacy and media literacy.
Consider a unit on the PYP key concept of change. Learners might use Research Skills to gather information on environmental shifts, then apply Communication Skills to articulate their findings in a structured report. They then collaborate in groups, using Social Skills, to generate novel ideas for sustainable practices, thereby synthesising new understandings and demonstrating Thinking Skills. This integrated practise ensures learners develop both conceptual understanding and the practical abilities to apply it.
The seven PYP key concepts, including Form, Function, and Causation, remain central to inquiry-based learning. While the concepts themselves are stable, the framework's language regarding their application has evolved, particularly with the 2018 enhancements. These updates reinforced the concepts' role in building learner agency and deeper inquiry.
Teachers 'specify' key concepts to frame a Unit of Inquiry and guide the first investigations. As inquiry develops, 'additional' or related concepts often emerge. Learners or teachers identify these concepts during the learning.
Neurodivergent learners, including those with autism or ADHD, often find abstract concepts challenging due to differences in processing and executive function. Explicit strategies are needed to make PYP key concepts accessible and meaningful for all learners. Teachers must provide concrete anchors and structured support to bridge the gap between abstract ideas and tangible understanding.
Visual aids are powerful tools for grounding abstract concepts, offering a concrete representation that can be revisited. Graphic organisers help learners map relationships and categorise information, reducing cognitive load (Dunlosky et al., 2013). For instance, when exploring the concept of "Causation" in a Year 4 science lesson on networks, a teacher might use a cause-and-effect graphic organiser.
Learners could draw or write about how deforestation (cause) leads to habitat loss (effect) and then to species endangerment (further effect). This visual structure helps them trace the sequence of events and understand the interconnectedness, making the abstract concept of causation visible and manageable.
Providing hands-on, concrete experiences allows neurodivergent learners to interact directly with concepts before moving to abstract discussions. Scaffolding these experiences ensures that learners receive the necessary support to engage successfully (Vygotsky, 1978). Consider teaching "Change" to Year 2 learners by observing the life cycle of a plant or insect over several weeks.
learners could document observations in a structured journal, drawing or writing about the daily transformations. The teacher might provide sentence starters or a word bank to support their descriptions, gradually reducing this support as learners become more confident in articulating the changes they observe.
Neurodivergent learners often need clear, consistent language and repeated exposure to learn new vocabulary and concepts. Teachers should define each key concept directly and use the same wording across different subjects (Rosenshine, 2012). For example, in a Year 5 history lesson about historical events, the teacher could introduce "Perspective" by saying, "Perspective means looking at something from someone else's point of view."
Throughout the lesson, the teacher would prompt learners to consider, "What was the perspective of the Roman soldier?" or "How might a Celtic villager's perspective differ?" This consistent use of the term and repeated questioning helps embed the concept, making it more accessible for learners who benefit from direct instruction and reinforcement.
The PYP key concepts are useful lenses, but they can be overextended. First, inquiry can fail when learners are asked to infer abstract relationships before they have enough secure knowledge. Kirschner, Sweller and Clark (2006) argue that minimally guided inquiry places heavy demands on working memory; this matters in early years and lower primary classrooms where vocabulary, background knowledge and self-regulation are still developing.
Second, some evidence often used to support concept-based inquiry is indirect. Hattie (2009) reports strong findings for concept mapping, but concept mapping is a structured strategy, not a full model of PYP teaching. Bergeron (2017) questions aspects of Hattie's meta-analytic method, including the way diverse studies are combined. Schools should therefore avoid treating one effect size as proof that all conceptual inquiry is effective.
Third, the research base brings cultural limits. Vygotsky (1978), Bruner (1960), Gardner (1983), Karpicke (2008) and Sweller (1988) are widely cited, but much of this work comes from Western academic contexts. Critical pedagogy, including Freire (1970), reminds teachers that concepts such as perspective and responsibility are not culturally neutral. Indigenous, migrant and working-class learners may bring knowledge traditions that do not fit neat planning templates.
These critiques do not weaken the value of the seven key concepts. They show that conceptual inquiry works best when teachers teach knowledge clearly, protect cognitive bandwidth, invite culturally grounded interpretations and assess transfer through dialogue, explanation and evidence.
