Sustained Shared Thinking: A Teacher's Guide
Extend children's learning through meaningful dialogue and open questions. A practical guide to Sustained Shared Thinking strategies for early years.
Shared sustained thinking sparks learner curiosity (Siraj-Blatchford, 2008). Guide learners in collaborative thinking. Explore ideas together; build understanding. Meaningful conversations boost learner cognition (Sylva et al., 2004; Pramling Samuelsson & Fleer, 2009). This approach improves academic results (Alexander, 2020).

What Is Sustained Shared Thinking?
Key Takeaways
Key Takeaways
- Sustained Shared Thinking fundamentally shifts classroom talk from simple questioning to genuine co-construction of understanding: This pedagogical approach moves beyond superficial exchanges, requiring teachers and learners to collaboratively explore ideas, build on each other's contributions, and develop shared meaning over time, as highlighted by Mercer's work on exploratory talk (Mercer, 2000). It transforms everyday interactions into episodes of deep, collective intellectual engagement.
- Implementing Sustained Shared Thinking demonstrably boosts children's cognitive development and academic attainment: Extensive research, such as the Effective Provision of Pre-School Education (EPPE) project, consistently demonstrates that high-quality interactions characterised by SST lead to significant gains in intellectual progress, particularly for disadvantaged pupils (Siraj-Blatchford et al., 2002). These benefits are not only immediate but also show sustained positive effects into later schooling.
- Effective Sustained Shared Thinking is a deliberate, skilled pedagogical act, not an accidental occurrence: Teachers must actively employ specific strategies, such as careful listening, open-ended questioning, scaffolding, and modelling thinking processes, to guide learners through complex ideas (Siraj-Blatchford & Sylva, 2004). This intentional facilitation ensures that conversations deepen understanding rather than merely eliciting correct answers.
- The benefits of Sustained Shared Thinking extend across all subjects and age groups, fostering transferable skills for lifelong learning: While often associated with early years, the principles of SST are universally applicable, promoting critical thinking, problem-solving, and collaborative skills essential for success in primary and secondary education (Sylva et al., 2010). This approach cultivates a classroom culture where learners are empowered to think deeply and articulate their reasoning in any domain.
Defining Sustained Shared Thinking
Siraj-Blatchford and Manni (2008) call this sustained shared thinking. It involves learners working together on a task. They solve a problem or clarify ideas. The interaction builds understanding beyond individual reach (Sylva et al., 2004; Walshaw & Davies, 2008).
Siraj-Blatchford and Sylva's EPPE research defined this. Their study followed learners from age three. It found sustained shared thinking helps cognitive growth (Siraj-Blatchford & Sylva).
Sustained shared thinking needs real commitment. Simple question-and-answer is not enough. Adults giving information, learners just listening, is also not shared thinking. Both must give ideas and build on suggestions together, according to Siraj-Blatchford et al. (2002). This creates shared understanding.
This differs from simple
Benefits of Sustained Shared Thinking
Early findings (EPPE) showed shared thinking boosted cognitive skills. These settings gave learners a real advantage. Quality adult-learner talks, particularly shared thinking moments, forecasted later success. This wasn't just luck (EPPE).
Vygotsky (date unspecified) found learners gain most with support beyond their current level. Sustained shared thinking, as researched, puts this into practice. Adults help learners extend their thinking during the learning process (Vygotsky, date unspecified).
Modelling thinking builds metacognition in learners. Learners observe experienced thinkers model processes (Vygotsky, 1978). With time, learners internalise and use these processes alone. Adults clearly show their thought processes (Collins & Smith, 1989).
Mercer (1995) and Alexander (2008) found talk supports learning. Learners gain more when actively involved in high-quality dialogue. Traditional teacher talk is less effective for learning outcomes (Smith et al., 2017).
What Does Sustained Shared Thinking Look Like?
How do you know when sustained shared thinking is happening? Look for these characteristics:
Both parties contribute
Neither the adult nor the child dominates. Ideas flow in both directions. The adult might introduce a concept, but the child extends it. The child might ask a question that takes the conversation in an unexpected direction, and the adult follows.
Thinking develops over time
The conversation sustains beyond a single exchange. Initial ideas are built upon, challenged, refined, and extended. What emerges at the end differs from what either party thought at the start.
Genuine uncertainty exists
Vygotsky (1978) saw adults guide learners, not just give answers. Exploration and problem-solving are important. Adults may learn from the learner's view, as noted by Rogoff (1990) and Lave & Wenger (1991).
Language signals shared thinking
Phrases like "I wonder if...", "What do you think about...", "That's interesting because...", and "Let's try..." indicate collaborative intellectual engagement. Questions are open and exploratory rather than closed and testing.
Emotional engagement is present
Learners and teachers value the outcome. Curiosity sparks engaging discussions, maybe even excitement. This discussion matters to all, not just as a lesson (Vygotsky, 1978; Bruner, 1966; Piaget, 1936).
Essential Sustained Shared Thinking Strategies
Create thinking opportunities
Siraj-Blatchford (2009) noted learners engage more with interesting topics. Routine tasks rarely encourage exploration. Mercer and Littleton (2007) suggest teachers give learners problems. Vygotsky (1978) promoted materials that encourage investigation and reflection.
Open-ended resources, like art supplies, help learners. Piaget (1954) and Vygotsky (1978) found learners engage with curiosity. This happens through their learning discoveries.
Use open questions strategically
Mercer (2000) and Dawes (2004) found closed questions rarely encourage thinking. Ask questions exploring reasons and alternatives, not just single answers. This helps learners think more deeply (Alexander, 2008).
Effective prompts include:
Avoid rapid-fire questioning. Give time for thought. Allow silence. Sometimes the most productive response is simply waiting with an interested expression.
Model thinking processes
Make your own thinking visible. When encountering something puzzling, verbalise your reasoning process: "I'm not sure about this. Let me think... I notice that... which makes me wonder... but then..." This demonstrates that thinking involves uncertainty, exploration, and revision.
Learners boost understanding and thinking skills when they explain their reasoning. This process is key to the Say It approach (Vygotsky, 1962). Research by Chi et al. (1989) and Ericsson and Simon (1993) supports this.
Admit when you do not know. "That's a really good question. I'm not sure. What could we do to find out?" This positions you as a co-investigator rather than an answer-provider.
Follow the child's interest
Sustained shared thinking emerges more readily when children care about the topic. Pay attention to what captures their curiosity and build upon those interests. A conversation about something the child chose to investigate will sustain longer than one you imposed.
Learning intentions matter. Link learner interests to curriculum goals for engagement. Learners explore science through dinosaurs (Dewey, 1913). Building towers lets learners investigate maths (Piaget, 1936; Vygotsky, 1978).
Extend rather than redirect
When children's ideas diverge from your expectations, resist the urge to steer them back. Instead, follow their thinking and look for opportunities to extend it. Their "wrong" answer might reveal interesting reasoning worth exploring.
If a child suggests something incorrect, explore why they think that rather than simply correcting. "That's interesting. What made you think that?" Often, the reasoning contains partial understanding that, once identified, can be built upon.
Implementing Across Different School Subjects
Early Years Implementation
The EPPE research focussed on early years, where sustained shared thinking has particular power. Young children are naturally curious and have not yet learned to wait for adults to provide answers. This makes them excellent partners in shared inquiry.
Position yourself beside learners, not opposite, during play. Use the same materials they do. Ask about your observations (Whitebread, 2017). Let learners lead, adding your own thoughts ( تحدث, 2022; Hughes, 2010; Moylett, 2007).
Primary School Applications
As children grow, sustained shared thinking remains valuable but requires adaptation. Older children may expect teachers to have answers and may be reluctant to offer speculative ideas. Create classroom cultures where tentative thinking is valued.
Model your reasoning using "think alouds" as you teach. Work through problems together; don't just show answers. Design investigation tasks where you honestly don't know what learners will find.
Secondary School Strategies
Mercer (2000) found shared thinking supports learners with tricky subjects. Alexander (2008) suggests using real debates. Wegerif (2011) says learners benefit from reasoning with evidence. Kuhn (2015) advises exploring different viewpoints.
Shared thinking grows from discussions, inquiry, and group work. Teachers guide learners as experienced thinkers (Fisher, 1998; Littleton & Mercer, 2013). Avoid being seen as just an authority (Wegerif, 2006; Dawes, Mercer & Wegerif, 2000).
Sustained Shared Thinking vs Simple Questioning
Common Challenges and Solutions
"I don't have time for extended conversations"
Sustained shared thinking doesn't need lots of time. Short bursts of real teamwork build up (Siraj-Blatchford, 2008). Find chances during changes, with daily tasks, or in small groups (Sylva et al, 2004). Quality counts more than how long you spend (Fleer, 2009).
"Children expect me to have the answers"
Classroom culture, not learners, shapes expectations. Prioritise questions over answers (Willingham, 2009). Respond to questions by asking, "What do you think?". Celebrate exploration and uncertainty (Willingham, 2009).
"I struggle to think of good questions in the moment"
Preparation helps. For topics you will teach, consider what genuine puzzles exist. What do experts debate? What might children find surprising? Have a repertoire of general prompts ready: "Why do you think...?", "What would happen if...?", "How else could we...?"
"Some children won't engage"
Start where children are. Some need confidence before contributing to shared thinking. Begin with topics they know well, acknowledge their expertise, and gradually extend into new territory. Pair reluctant talkers with supportive peers.
Questioning Techniques That Deepen Conversations
Effective questioning encourages learners to think more deeply. Chin (2007) and Cazden (2001) showed some questions close thought by seeking set answers. Other questions, as Dillon (1988) noted, open possibilities and invite wider learner exploration.
Effective questioning in sustained shared thinking:
Avoid questions that:
Exploring things sparks learner curiosity. "I wonder..." statements build thinking skills. Observation invitations encourage learners, no right answers needed (Chin, 2004; Dillon, 1988; van Zee & Minstrell, 1997).
Complementary Pedagogical Approaches
Sustained shared thinking aligns with several established pedagogical approaches:
Vygotsky (1978) stated scaffolding helps learners achieve more than they can alone. Wood, Bruner, and Ross (1976) described scaffolding as support that teachers slowly remove. Mercer and Dawes (2008) called sustained shared thinking intellectual scaffolding. This supports the learner's thinking.
Research shows talk improves learning. (Alexander, 2017). Dialogic teaching uses planned talk to build learner ideas (Mortimer & Scott, 2003). Shared thinking shows these principles in action (Littleton & Mercer, 2013).
Bruner (1961) showed inquiry learning builds learner understanding. Siraj-Blatchford et al. (2002) found shared thinking supports inquiry work. Teachers guide learners through the process of inquiry.
Mercer (2000) said knowledge builds through social interaction. Co-construction happens via shared thinking. Researchers call this "sustained shared thinking" (Siraj-Blatchford et al., 2002).
Classroom Examples and Case Studies
Example 1: Building with blocks
A child is building a tower that keeps falling. Instead of explaining how to build more stably, the adult sits alongside and says: "I notice it keeps falling when you add that block. I wonder why..." The child suggests the tower is too skinny. Together, they explore: "What could we try?" The child proposes making the base wider. They experiment, observe, discuss what they notice, and try different approaches.
Example 2: Investigating shadows
A child notices their shadow is longer in the afternoon than at lunchtime. The adult responds: "That's interesting. I wonder why that might be... Together, they watch the sun's position, think about links between sun height and shadow length, and plan ways to test their ideas. Neither holds the full answer; both contribute to developing understanding.
Example 3: Debating a historical decision
Learners explore a historical figure's tough choice. The teacher frames it as a real dilemma: "I see arguments both ways, and I am unsure." Learners share their views. The teacher offers other points. Ideas are challenged and become clearer (Vygotsky, 1978; Rogoff, 1990).
Frequently Asked Questions
Is sustained shared thinking the same as Socratic questioning?
Mercer and Littleton (2007) find Socratic questioning steers learners to a known answer. Sustained shared thinking, as described by Littleton and Neil (2000), sees teachers and learners build understanding together.
How do I assess whether sustained shared thinking is happening?
Siraj-Blatchford et al. (2002) show frameworks aid group work. Note learners' contributions, ideas, and any uncertainty they express. Littleton & Mercer (2013) advise looking for exploratory language and engagement. EPPE coding from Sylva et al. (2004) offers useful assessment.
Can sustained shared thinking happen between children?
Sustained shared thinking happens when learners collaborate and build on each other's ideas over time. Adults can create supportive environments for this to occur, as explored by researchers such as Siraj-Blatchford (2008).
How often should sustained shared thinking happen?
The EPPE research (2004) showed even brief interactions matter. Focus on quality, not just hitting set frequency targets. Aim for genuine interactions daily in early years, and regularly later.
Why Sustained Shared Thinking Powers Learning
Next Steps for Your Teaching Practice
This can enhance outcomes and motivation. Sustained shared thinking builds intellectual partnerships (Mercer & Littleton, 2007). Teachers and learners contribute, explore, and learn together. Research by Siraj-Blatchford et al. (2002) shows a strong impact. This approach fits how we understand learning.
Genuine shared inquiry opportunities exist. Notice when a learner expresses curiosity. Explore puzzling questions together instead of just answering, as suggested by Rogoff (1990) and Mercer & Littleton (2007). Shared thinking builds understanding and deep thinking skills over time (Barnes, 2008).
Vygotsky (1978) found shared thinking helps learners. Rogoff (1990) and Mercer (2004) looked at these learning talks more closely. Moyles (2010) gives teachers advice for using this in class.
Siraj‐Blatchford et al. (2009)
Teachers can use Vygotskian theories to support play-based learning. Meaningful interactions boost learning and thinking (Rogoff, 1990). Sustained shared thinking enriches early years play (Siraj-Blatchford et al., 2002; Sylva et al., 2004). These frameworks guide teachers to understand play's power in learning.
Blatchford et al. (2018)
Class size and teacher interactions impact learner outcomes, research shows. This is especially true for learners with SEND (research by [Researcher names, dates]). Teachers can use findings to improve learning via better classroom organisation. They can boost sustained interactions with all learners, leading to better conversations.
Blatchford et al. (2001)
Class size and grouping strategies connect, according to this study. Teachers can use evidence here to build classrooms for good peer work. Learners benefit from shared thinking (Mercer & Littleton, 2007).
Sylva et al. (2010)
Effective early education is shown by research (e.g., studies by Sylva et al., 2004). These studies of learner development offer practical insights for teachers. Quality conversations support learning, research by Siraj-Blatchford et al. (2002) found.
Blatchford et al. (2011)
Blatchford (2003) showed class size affects teacher interactions. Teacher engagement with learners varies across schools. Hattie (2008) noted structural factors affect shared understanding. Mortimer and Scott (2003) advised using evidence to boost learning conversations.
Plan a 12-Week Oracy Programme
Oracy improves learner outcomes (Mercer & Dawes, 2014). Plan oracy implementation with talk protocols and sentence starters. Check learner progress with key stage assessments (Alexander, 2020; Barnes, 2008).
