Assistive Technology
Assistive Technology (AT)
Assistive Technology (AT) in education refers to the range of tools, devices, and strategies that enhance access, participation, and learning outcomes for students with neurodiverse profiles. AT plays a vital role in reducing learning barriers and enabling all learners to engage with the curriculum in ways that reflect their individual strengths and needs. The World Health Organization (WHO) and UNICEF (2022) highlight that access to assistive technology for children with disabilities is often the first step toward inclusive childhood development, as these tools foster autonomy, communication, and meaningful participation in everyday learning.
Expanding on this, UNICEF (2022) and other global frameworks categorize assistive technologies into three broad types as low-tech, mid-tech, and high-tech.
Assistive Technology Tools
Low-tech tools
Communication books, symbol charts, visual schedules, and graphic organizers are low-cost, easy to use, and require minimal maintenance.
Mid-tech tools
Includes adaptive keyboards, talking calculators, and simple battery-operated communication aids that may involve limited electronic components.
High-tech tools
Advanced digital systems such as tablets, speech-generating devices, or eye-gaze technologies that often require specialized training and resources.
While high-tech innovations can provide sophisticated support, research suggests that low- and mid-tech AT tools are the most practical, cost-effective, and sustainable options for Sri Lankan classrooms. These tools can be created or adapted using locally available materials and integrated seamlessly into everyday teaching and assessment practices.
Globally and regionally, access to assistive technology is guided by the 5Ps Framework developed by the World Health Organization; People, Policy, Products, Provision, and Personnel. This framework provides a holistic approach to building inclusive education systems. For Sri Lanka, the 5Ps model offers a roadmap to strengthen AT access through improved teacher training, policy implementation, and the local development of affordable assistive products that meet diverse learner needs across both rural and urban settings.

Strategies for Self-Regulation
Fidget Tools
Fidget tools are small, handheld objects that help students focus, manage sensory needs, and release excess energy in appropriate ways. Examples include stress balls, fidget spinners, tangles, putty, textured keychains, and stretchy bands. When used thoughtfully, fidget tools can improve attention, reduce anxiety, and support students who struggle with sitting still or maintaining focus such as those with ADHD or sensory processing differences.
Teachers can guide effective use by introducing fidget tools intentionally, setting boundaries for when and how they’re used, and choosing tools that are quiet and non-distracting. The goal is to support self-regulation and concentration without interrupting classroom learning.
Calming Strategies
Calming strategies are techniques that help students manage stress, emotions, and sensory overload. These strategies teach self-awareness and emotional control, empowering students to respond to challenges in positive ways.
Common calming strategies include:
Butterfly Breathing – Imagining or tracing a butterfly’s wings while slowly inhale and exhale to feel calm and centered.
Rainbow Breathing – Imagining or tracing a rainbow in the air while inhaling and exhaling to promote calmness.
Five-Finger Breathing – Tracing each finger with the opposite hand while breathing in and out to focus and ground attention.
Progressive Muscle Relaxation – Tensing and relaxing muscles to release physical stress.
Mindful Listening or Visualization – Focusing on sounds or mental images of calm places to settle the mind.
By incorporating these practices into the classroom routine, teachers can create a supportive, emotionally safe environment that encourages self-regulation, focus, and a positive mindset for all learners.
