What Does “A Calm Brain Is a Thinking Brain” Mean?
“A calm brain is a thinking brain” is the mantra at the heart of Brain-SET. It is also one of the most easily misunderstood ideas in the approach. It does not mean children must be silent, still or perfectly regulated before learning can happen. It means that the conditions around a learner matter. Safety, connection, predictability, sensory experience, movement and relationships can all influence how people experience an environment and participate in learning.
Dr Kathryn Murray developed Brain-SET through more than 40 years in education, drawing together research, educational theories, neuroscience, environmental design and practical experience. Her approach asks educators to consider how these conditions can be intentionally supported through both teaching practice and environment design.
Calm Is Not the Same as Quiet
A joyful early childhood room can be noisy. Children can laugh, sing, build, move, negotiate and experiment. A classroom can be active without being chaotic. Calm is better understood as a sense of enough safety, connection and support to participate in what is happening. A calm brain is a thinking brain because a sense of safety and connection can create better conditions for children to participate, explore and engage.
This is important because “calm classroom” is sometimes interpreted as a behaviour-management goal. Brain-SET takes a different direction. Instead of asking only how to make children quieter, educators can ask what the environment and teaching practice are communicating and whether they are supporting meaningful engagement.
Relationships Help Create the Conditions for Thinking
The developing brain is deeply connected to relationships. The Harvard Center on the Developing Child explains serve-and-return interactions as responsive back-and-forth exchanges that help build brain architecture and support early language and social development.
This matters for Brain-SET because a learning environment is never only physical. The adult’s presence, responsiveness and relationship with children are part of the environment children experience.
A thoughtfully arranged room cannot compensate for disconnected relationships. Equally, strong relationships can be supported by environments that make interaction, access and participation easier.
What the Environment Can Influence
The environment can influence how people move, where they gather, what they notice, how independently they access resources and how easily they transition between activities. It can also influence sensory experience through sound, visual complexity, spatial density, lighting and materials. The broader developmental environment also matters. The Harvard Center on the Developing Child explains how the environments surrounding children can shape their development and experiences.
None of these factors should be treated as a universal formula. The same environment can work differently for different children. That is why Brain-SET emphasises observation and purposeful adaptation rather than prescribing one perfect classroom.
The idea that a calm brain is a thinking brain therefore does not mean creating identical environments for every learner. It means paying attention to the conditions that help people feel safe enough to participate and think.
From Behaviour Management to Environmental Thinking
Imagine a group of children who repeatedly become unsettled during transitions. A traditional response might focus entirely on behaviour: more reminders, more instructions, more consequences. An environmental approach asks additional questions. Is the transition predictable? Can children see what comes next? Is the pathway crowded? Are too many groups moving at once? Is there enough time? Are adults positioned where support is needed?
The answer may still involve teaching a new routine. But the environment becomes part of the investigation rather than being ignored.
The Brain-SET S.E.T. Idea
Brain-SET uses the language of S.E.T. to describe three priorities: **Safe, Engaged and open to Thinking**. These priorities connect to the approach’s 3 Pillars of Design and 16 Design Elements.
The point is not to turn a classroom into a checklist. The framework gives educators a common language for reflecting on what is happening in the environment and why.

Designing for Regulation Without Creating a “Calm Corner” Culture
A calm space can be useful, but regulation should not be confined to one corner of a classroom. The whole environment can contribute to regulation. Clear pathways, predictable routines, accessible resources, thoughtful acoustics, movement opportunities and spaces with different sensory qualities can all matter.
The goal is not to create a room where children are constantly being moved into a designated calming area. It is to create an environment with enough flexibility that children can participate in different ways. A calm brain is a thinking brain, but calm does not have to mean stillness or silence. The aim is to provide enough flexibility for children to regulate, move, connect and remain engaged in learning.
Why This Matters for Neurodivergent Learners
Neurodivergent learners may experience sensory and social environments differently. A noisy room, crowded transition or visually complex space may create barriers for one learner while another child barely notices it.
Brain-SET encourages educators to consider these differences as part of environment design. That does not mean assuming that all neurodivergent children need the same thing. It means designing with variation in mind and observing individual responses.
A Calm Brain Can Still Be Curious
One of the most important parts of Kathryn’s vision for Brain-SET is that calm should not become bland. The desired environment is joyful, curious and creative. Children should still be able to explore, take appropriate risks, ask questions, make noise, move and become deeply involved in play.
A calm environment is therefore not one with the least activity. It is one where activity has somewhere to go and where children have meaningful ways to participate.
Applying the Mantra in Practice
For educators, try translating the mantra into three reflective questions:
- What helps the people in this environment feel safe and connected?
- What helps children become genuinely engaged rather than merely compliant?
- What environmental conditions make it easier for children to explore, communicate and think?
In practice, “a calm brain is a thinking brain” becomes a question about conditions rather than a rule about behaviour. Then observe. What changes? What stays the same? What surprises you? What does the team need to adjust?
Brain-SET training supports educators and leaders to connect this type of thinking with practical environment design, professional learning, coaching and mentoring.
A Calm Brain Is a Thinking Brain in Australia
For early childhood educators and schools across Australia, including Queensland and the Sunshine Coast, the mantra provides a simple entry point into a much deeper conversation. Instead of treating wellbeing, learning and environment design as separate subjects, educators can examine how they interact in everyday practice.
That is the value of a memorable idea: it can help a team return to a shared principle when making dozens of small decisions throughout the day.
What Calm Looks Like in Different Environments
Calm will not look identical in a baby room, a preschool environment, a primary classroom or a workplace. In one setting, calm may involve predictable routines and close adult responsiveness. In another, it may mean having clear zones for collaboration and focused work. The principle remains the same while the application changes.
This is why Brain-SET does not prescribe one aesthetic. A Brain-SET environment is not defined by a particular colour palette, furniture brand or room layout. It is defined by purposeful decisions about the people, activities and context.
Calm, Curiosity and Creativity Can Coexist
A powerful learning environment can be both calm and stimulating. Children need opportunities to wonder, experiment, move, make mistakes and try again. The aim is not to remove challenge or novelty. It is to create enough security and connection for children to engage with challenge rather than being overwhelmed by unnecessary environmental demands.
That is why Kathryn describes the desired environment as joyful, curious and creative. Calm is the foundation, not the destination.
A Reflection Tool for Educator Teams
At the end of a day, a team could ask three simple questions: When did children appear most deeply engaged? When did the environment seem to make participation harder? What could we test tomorrow? These questions turn the mantra into a habit of observation rather than a slogan.
The Mantra as a Leadership Principle
For leaders, the mantra can become a question about organisational culture as well as classroom design. Are educators themselves experiencing enough safety, connection and support to think creatively about their practice? Adult wellbeing and professional learning are part of the environment story too.
This is one reason Brain-SET extends beyond room setup into training, coaching and mentoring. A team needs the conditions to reflect if it is expected to create reflective environments for children.
Conclusion: Calm Creates Possibility
“A calm brain is a thinking brain” is not a promise that calm classrooms automatically produce better learning. It is an invitation to consider the conditions in which learning takes place.
Brain-SET turns that invitation into a practical pedagogy. It connects environment, relationships, teaching practice, development and regulation and asks educators to keep refining the spaces in which children and adults learn.
The goal is not silence. The goal is possibility: a learning environment where children can feel safe enough to connect, engaged enough to explore and supported enough to think.
