Understanding how the sensory environment can affect a student’s ability to learn, participate, and feel successful

WHAT IS SENSORY PROCESSING?

Sensory processing is the brain’s ability to receive, organize, interpret, and respond to information from our bodies and the environment.

We are constantly receiving sensory information — even when we are not consciously aware of it.

Our brain processes information from:

👀 Vision — lights, movement, visual clutter
👂 Hearing — voices, bells, chairs moving, background noise
✋ Touch — clothing, materials, accidental contact
🦶 Movement — moving, sitting, walking, changes in position
💪 Body awareness — knowing where our body is and how much force to use
👃 Smell & Taste — food, cleaning products, classroom smells
❤️ Internal body signals — hunger, thirst, fatigue, temperature, toileting needs

Everyone processes sensory information differently. Sensory differences are not necessarily a problem — they become important when they make it harder for a student to participate in everyday activities.

WHY DOES THIS MATTER IN THE CLASSROOM?

A classroom is a sensory-rich environment.

Imagine trying to complete a math problem while:

🔊 hearing conversations, scraping chairs and hallway noise
💡 noticing bright or flickering lights
👀 seeing movement around you
🪑 trying to remain seated and organized
✋ managing uncomfortable clothing or materials
🧠 remembering instructions and completing the task

For some students, their brain may need to work harder to process this information.

When sensory demands are high, there may be less available energy for learning.

This can affect:

  • Attention and focus
  • Listening and following direction
  • Listening and following direction
  • Motor coordination and handwriting
  • Sitting or participating during lessons
  • Transitions between activities
  • Emotional regulation
  • Beginning or completing tasks
  • Tolerance for busy or unpredictable environments
  • Social participation and group activities

Research indicates that sensory processing differences can influence children’s participation across everyday occupations, including school participation. (PubMed)

 

WHAT MIGHT WE NOTICE?

A student experiencing sensory overload or sensory mismatch might:

SEEK MORE INPUT

  • Move frequently or seek opportunities to push, pull, carry or crash
  • Touch objects or people
  • Fidget or change positions often
  • Enjoy movement and active learning

AVOID OR EXPERIENCE TOO MUCH INPUT

  • Cover their ears
  • Avoid certain textures or materials
  • Become overwhelmed in busy spaces
  • Find assemblies, cafeterias or crowded hallways difficult
  • Need breaks from visually or auditorily busy environments

HAVE DIFFICULTY NOTICING INPUT

  • Miss verbal directions
  • Not notice their name being called
  • Seem unaware of body position or personal space
  • Use too much or too little force

IMPORTANT: These behaviours are communication. Instead of asking only,
“How do we stop this behaviour?”
we can also ask,

“What might this student be communicating or needing?”

 

HOW CAN WE SUPPORT PARTICIPATION?

The goal is not to remove all sensory input or make every classroom the same.

The goal is to match the environment and support the student’s needs so they can access learning and participate meaningfully.

Try:

🏃 MOVEMENT

  • Build purposeful movement into the day
  • Offer opportunities to stand, stretch, walk or carry materials
  • Consider movement before or during demanding tasks

🔇 SOUND

  • Reduce unnecessary background noise
  • Offer a quieter workspace when appropriate
  • Prepare students for loud or unexpected sounds

👀 VISUALS

  • Reduce unnecessary visual clutter
  • Use clear, predictable visual information
  • Provide a workspace with fewer competing distractions when needed

💪 BODY AWARENESS

  • Use pushing, pulling, carrying or other purposeful “heavy work” activities when appropriate
  • Incorporate hands-on learning and active participation

🧩 CHOICE & PREDICTABILITY

  • Use visual schedules or First–Then language
  • Give meaningful choices where possible
  • Prepare students for changes in routines or environments

❤️ CO-REGULATION

  • Notice signs of rising stress early
  • Use calm, supportive adult interaction
  • Allow time and space to regulate rather than expecting learning during overwhelm

 

THE BIG IDEA

REGULATION SUPPORTS ACCESS TO LEARNING.

A student does not need to “look regulated” in order to learn, and movement or sensory tools should not be used simply to make a child sit still.

Instead, we want to ask:

“What does this student need in order to participate?”

Sensory supports are most effective when they are individualized, purposeful, connected to a meaningful school activity, and monitored to determine whether they are actually helping participation. Current evidence supports using clinical reasoning and understanding the individual student and school context when selecting sensory supports. (PubMed)

A SCHOOL-BASED OT CAN HELP

Occupational therapists can work collaboratively with students, families and school teams to understand how sensory processing, motor skills, regulation, environmental demands and task expectations may be affecting school participation.

The focus is not on changing who the student is.

The focus is on changing the fit between the student, the activity and the environment.

Prepared from a school-based Occupational Therapy perspective. Sensory strategies should be individualized based on the student’s strengths, needs, goals and response to intervention.
