What is Strewing?
Understanding What Is Strewing
The Origins of Strewing
The concept of strewing originates within the unschooling movement and is widely attributed to unschooling advocate Sandra Dodd. It emerged in the 1990s through home-schooling communities and was later developed through her writing and practical guidance for families engaging in self-directed education.
Within its original context, strewing was not designed as a strategy for demand avoidance. Instead, it formed part of a broader philosophy of natural, interest-led learning, where children are supported to engage with the world in ways that feel meaningful and self-directed.
Sandra Dodd described strewing as a way of enriching a child’s environment by bringing interesting things into their path, without requiring interaction or turning those offerings into structured lessons.
Core Principles of Strewing
At its core, strewing involves:
Leaving objects, ideas, or experiences available
Allowing the child to notice or ignore them
Removing expectations or conditions
Trusting that interest may emerge naturally
Importantly, strewing is grounded in a non-directive approach. This means that the adult does not attach any expectation that the child must engage, learn, or respond in a particular way.
What Does Strewing Look Like in Practice?
In everyday life, strewing can look like:
Placing a book, puzzle, or object in a shared space
Bringing home something interesting discovered during the day
Introducing ideas through everyday conversation
Creating an environment rich in possibilities rather than instructions
Over time, Sandra Dodd emphasised that strewing becomes less of a deliberate technique and more of a way of living, where the environment is continuously shaped to support curiosity and exploration.
Strewing Within Unschooling Philosophy
Strewing sits within the wider framework of unschooling, which is based on the understanding that learning is:
Naturally occurring
Interest-driven
Embedded in everyday life
Not dependent on formal instruction or curriculum
Within this model, the role of the adult is not to direct learning, but to:
Create access to experiences
Expand opportunities
Support exploration
Trust the child’s internal motivation
Rather than asking, prompting, or structuring learning, the adult curates the environment.
An Important Distinction for PDA Practice
While strewing is now widely used within PDA (Persistent Demand Avoidance) and demand avoidance support, it is important to be clear:
Strewing was not originally developed as a PDA strategy.
However, its core principles align closely with what we now understand about:
Autonomy and control
Nervous system safety
Demand perception
Relational dynamics
For Autistic individuals with a PDA profile, where even subtle expectations can activate a threat response, strewing offers a powerful way of:
Removing interpersonal pressure
Preserving autonomy
Allowing engagement to emerge without demand
This makes it a highly compatible and effective approach when used within a neuroaffirmative framework.
Strewing for PDA
In PDA-informed practice, strewing has evolved from an educational concept into a relational and regulatory support strategy.
The key shift is this:
From:
Creating opportunities for learning
To:
Reducing demand and supporting safe engagement
While the method may appear similar, the intention is fundamentally different.
Within a PDA framework, strewing is used to:
Lower threat responses
Support nervous system regulation
Maintain equality in interaction
Protect autonomy
Create conditions where engagement becomes possible
The Origins of Strewing
Understanding where strewing comes from is essential for using it with integrity.
Without this context, strewing can easily be misunderstood as:
A subtle way to prompt behaviour
A strategy to increase participation
A tool to achieve specific outcomes
This shifts it back into a demand-based interaction, which is not supportive for PDA.
Returning to its origins reminds us that strewing is fundamentally about:
Offering, not directing
Trusting, not controlling
Inviting, not expecting
Continue Exploring PDA
Understanding pressure is one part of the wider picture.

A Note on the Evidence Base
Research specifically examining PDA remains in its relative infancy, and understandings of PDA continue to evolve. There remains considerable debate within research and clinical communities regarding its conceptualisation, terminology and relationship with Autism, and there is still much to learn directly from PDA people about the processes underlying their experiences and the forms of support they find helpful.
There is also not currently a robust evidence base specifically establishing strewing as an intervention for PDA. For that reason, I do not present strewing here as an evidence-based treatment, prescribed strategy or universally appropriate approach.
This article represents an evolving synthesis of my own lived experience as an Autistic PDA person and parent, together with emerging PDA research and theory, wider Autism research and neuroaffirmative understandings of autonomy, Monotropism, sensory experience, executive functioning, regulation, relational safety and person-centred support. Lived experience is particularly important within an emerging field, while also being recognised as experience rather than evidence that every PDA person will share the same needs or perspectives.
PDA people are not a homogeneous group. An approach that feels spacious, respectful and autonomy-supportive for one person may feel intrusive, uncertain or pressurising to another. The individual person's communication, preferences, boundaries and lived experience should therefore remain central to any support.
As the research base develops, and as knowledge generated by PDA people themselves continues to expand, this article will continue to be reviewed and updated. The intention is not to present a fixed or definitive model of PDA, but to reflect the best available understanding while remaining open to changing that understanding as we learn more.
