Assimilation vs Accommodation
Discover Piaget's assimilation and accommodation theory. Learn how these cognitive processes shape children's intellectual growth and understanding.
What is Assimilation and Accommodation?
Assimilation and accommodation are two key ideas from systems theory of how children learn. These two processes explain how we take in new information and make sense of the world around us.
Key Takeaways
- Beyond Adding Knowledge: Why your struggling readers might not be 'slow learners' but experiencing accommodation overload, and how to rebalance their learning
- The Block Play Secret: How simple classroom activities trigger both assimilation and accommodation, creating deeper learning than traditional instruction methods
- Spotting the Shift: Recognise the exact moment pupils move from assimilation to accommodation, and why missing this derails their understanding
- Cultural Schema Blindness: The overlooked factor that makes some pupils struggle: when your teaching assumes cultural schemathat don't exist in their experience
| Aspect | Assimilation | Accommodation |
|---|---|---|
| Definition | Fitting new information into existing knowledge structures | Changing existing knowledge structures to fit new information |
| Key Feature | Like adding a book to an existing shelf | Like building a new shelf when the old one cannot hold the book |
| Example | Child sees a new dog breed and still recognises it as a dog | Child learns a cat is not a dog and creates a new mental category |
| Classroom Use | Building on familiar concepts through block play and hands-on activities | Group work that challenges existing views and pushes new thinking |
| Best For | Quick learning when new information fits existing schemas | Learning complex ideas and correcting misconceptions |
Assimilation happens when we fit new information into what we already know. Think of it like adding a new book to an existing shelf. The new book fits in with what is already there.
Accommodation happens when we change what we already know to fit new information. This is like building a new shelf because the old one cannot hold the new book. We have to adjust our thinking.
Both processes work together to help us learn and grow, much like Bruner's spiral curriculum approach. Understanding how they work can help teachers develop effective pedagogy and teaching strategiesin the classroom.
What is assimilation in child development?
Assimilation is the process where children take new information and fit it into their existing knowledge structures or schemas. For example, when a child who knows what a dog is sees a new breed and still recognises it as a dog, they're using assimilation. This process helps children make sense of new experiences quickly by connecting them to what they already understand.
Assimilation is how we take in new information and connect it to our existing knowledge. When children learn something new that fits with what they already understand, they are using assimilation.
For example, a child who knows what a dog is might see a new breed and still call it a dog. They have fitted this new animal into their existing idea of what dogs look like.
This process helps us make sense of new experiences quickly. We use what we already know as a starting point. This makes learning faster because we do not have to start from scratch every time.
Assimilation helps children build on their . A schema is a mental framework that helps us organise and understand information. The more we learn, the stronger our schemas become.
How does accommodation differ from assimilation in learning?
Accommodation occurs when children must change their existing mental structures to incorporate new information that doesn't fit their current understanding. Unlike assimilation which adds to existing knowledge, accommodation requires restructuring what the child already knows. This happens when a child learns that not all four-legged animals are dogs and must create new categories for cats, horses, and other animals.
Accommodation is what happens when new information does not fit into our existing knowledge. We have to change our thinking to make room for new ideas.
For example, a child who thinks all four-legged animals are dogs might see a cat. When they learn it is not a dog, they must create a new category in their mind. This is accommodation.
Accommodation takes more effort than assimilation. It requires us to rethink what we thought we knew. But this process is key to learning complex ideas and correcting mistakes in our understanding.
Both assimilation and accommodation work together. As children grow, they constantly shift between these two processes. This helps them build more accurate and detailed mental models of the world.

How can teachers promote assimilation and accommodation in students?
Teachers can encourage assimilation by connecting new lessons to students' prior knowledgeand using familiar examples before introducing complex concepts. To promote accommodation, teachers should present challenging scenarios that don't fit existing schemas and guide students through restructuring their understanding. The key is recognising when students are ready to move from assimilation to accommodation and providing appropriate support during this transition.
Teachers can use practical strategies to help students use both assimilation and accommodation. and creative activities are great ways to do this.
Block play helps children build on what they already know about shapes and space. At the same time, it challenges them to try new structures. This mix of familiar and new pushes both processes.
Group work is another powerful tool. When children share ideas with each other, they often hear views that challenge their own thinking. This can lead to accommodation as they adjust their mental models.
works well because it gives children real experiences to build on. When students can touch, move, and explore, they form stronger connections between new and existing knowledge.

What are practical examples of assimilation and accommodation in the classroom?
Common classroom examples include block play where children first assimilate by stacking familiar shapes, then accommodate when discovering balance principles. In reading, students assimilate when recognising similar word patterns but accommodate when encountering exceptions to phonics rules. Math provides clear examples when students assimilate addition facts but must accommodate to understand that multiplication isn't just repeated addition.
Here are examples of how assimilation and accommodation work in different subjects:
1. Language Arts (Year 2): A child learns that two words can join to make compound words. They adjust their thinking to understand that combined words create new meanings.
2. Maths (Year 5): A student learns that ½ and 2/4 are the same. They must accommodate when they discover that not all fractions work this way.
3. Science (Year 8): Students add the idea of food chains to what they know about animals. They accommodate when they learn about complex food webs that do not follow simple chains.
4. History (Year 10): A student fits a historical event into a timeline they know. They accommodate when they learn about cultural context that changes how they see that event.
5. PE (All ages): A child learns a new game by comparing it to one they know. They accommodate when new rules require different actions.
Teachers can guide these learning moments by providing experiences that stretch students' current thinking. This helps children grow and develop stronger understanding.
How do cultural differences affect assimilation and accommodation in learning?
Cultural schema blindness occurs when teaching assumes background knowledge that some students don't possess due to different cultural experiences. Students from diverse backgrounds may need more accommodation than assimilation because their existing schemas differ significantly from classroom content. Teachers must recognise these differences and provide culturally relevant examples to help all students build appropriate mental frameworks.
Every child learns differently. Teachers need to adapt their teaching to meet the assimilation and accommodation needs of all students.
Children with or other learning differences may need extra support. , which uses sight, sound, and touch together, can help these students take in new information more easily.
Cultural backgrounds also shape how children learn. Students bring different experiences and knowledge to the classroom. Teachers should value and build on this diversity.
By creating an , teachers can help all children develop their thinking skills. This means giving every student the chance to both build on what they know and stretch into new ideas.
What does research say about assimilation and accommodation in education?
Research shows that struggling readers often experience accommodation overload rather than slow learning, requiring teachers to rebalance their instruction toward more assimilation opportunities. Studies indicate that recognising the exact moment students shift from assimilation to accommodation is crucial for preventing learning breakdowns. Current research emphasises that both processes must work together, with teachers providing appropriate scaffoldingbased on each student's cognitive load capacity.
Here are five important studies on this topic:
1. Block (1982): Personality Development
This paper looks at how assimilation and accommodation connect to personality growth. It suggests that balancing these processes helps people manage stress and build strong ways of seeing the world.
2. Zhang Fen (2003): Modern Teaching
This study explores how teachers can match their methods to students' thinking patterns. It shows how understanding these processes can improve teaching.
3. Zhong, Songxiang & Lin (2015): Computer Models
These researchers built computer models that copy how humans learn through assimilation and accommodation. Their work helps us understand learning in new ways.
4. Renner, Abraham & Birnie (1986): Learning Physics
This study looked at how high school students learn physics. It found clear evidence of assimilation and accommodation happening as students grasped new concepts.
5. Mayer (1977): Instruction Sequencing
This research examined how the order of teaching affects learning. It showed that matching teaching to students' existing knowledge helps them learn more.
Together, these studies show how assimilation and accommodation shape learning. Teachers who understand these processes can create better learning experiences for their students.
Frequently Asked Questions
What is the practical difference between assimilation and accommodation in the classroom?
Assimilation is like adding a book to an existing shelf, where students fit new information into their current knowledge structures. Accommodation is like building a new shelf entirely, requiring students to change their existing mental frameworks to incorporate information that doesn't fit what they already know.
How can teachers recognise when a student is ready to move from assimilation to accommodation?
Teachers should watch for moments when students encounter information that clearly contradicts their existing understanding or when familiar strategies stop working. This transition point is crucial because missing it can derail student understanding and leave them struggling with concepts that don't fit their current mental models.
What classroom activities effectively promote both assimilation and accommodation?
Block play is particularly effective as it allows children to build on familiar concepts about shapes and space whilst challenging them with new structural problems. Group work also promotes both processes by exposing students to different perspectives that may challenge their existing thinking and require mental restructuring.
Why might some students struggle more with accommodation than others?
Cultural schema blindness can cause significant challenges when teaching assumes background knowledge that students from different cultural experiences don't possess. These students may need more accommodation than assimilation because their existing mental frameworks differ substantially from the assumed cultural context of the curriculum.
How can teachers support students experiencing 'accommodation overload'?
Teachers should rebalance learning by ensuring students have sufficient opportunities for assimilation before pushing for accommodation. Providing more hands-on experiences and connecting new concepts to students' actual existing knowledge, rather than assumed knowledge, helps prevent cognitive overload during the restructuring process.
What are clear subject-specific examples of assimilation and accommodation in action?
In mathematics, students use assimilation when learning that ½ equals 2/4, but need accommodation when discovering fraction equivalencies don't always work the same way. In reading, children assimilate familiar phonics patterns but must accommodate when encountering exceptions to these rules that require new mental categories.
How do assimilation and accommodation work together to build deeper understanding?
Both processes work in tandem as students constantly shift between fitting new information into existing schemas and restructuring their mental models when necessary. This dynamic interaction helps children build more accurate and detailed understanding of the world, moving beyond simple knowledge addition to genuine conceptual development.

Mishra et al. (2023)
This paper analyses social constructivist learning theory and its pedagogical models, focusing on learner-centered approaches that emphasise student autonomy and flexibility in learning environments. Teachers studying assimilation vs accommodation will find this relevant because constructivist theory provides practical frameworks for creating learning experiences that support both processes, helping educators understand how students actively build knowledge through social interaction and personal meaning-making.
The Role of Equilibration in Piaget’s Theory of Cognitive Development and Its Implication for Receptive Skills: A Theoretical Study View study ↗52 citations
Bormanaki et al. (2017)
This theoretical study examines Piaget's concept of equilibration, which is the process by which learners balance assimilation and accommodation to achieve cognitive stability when encountering new information. This paper is directly relevant to teachers learning about assimilation vs accommodation because equilibration is the core mechanism that determines when students will assimilate new information into existing schemas versus when they will need to accommodate by modifying their mental frameworks.
Ahmed et al. (2018)
This study explores how ethnically diverse students use schema theory to understand Shakespeare's Romeo and Juliet, examining how their existing cultural knowledge frameworks influence their interpretation of the text. Teachers will find this relevant to assimilation vs accommodation because it provides a concrete example of how students' prior cultural schemas either help them assimilate new literary concepts or require them to accommodate different cultural perspectives when reading classic literature.
