Introduction
Sensory-based strategies have become a central component of special education interventions, particularly for students on the autism spectrum. These strategies are designed to meet the sensory needs of students who experience sensory processing challenges, enabling them to regulate their behavior, enhance their focus, and participate fully in educational settings. As students with Autism Spectrum Disorder (ASD) frequently struggle with processing sensory information—whether it’s sounds, lights, textures, or movements—tailored interventions have been developed to improve their learning outcomes and overall well-being in the classroom.
Dr. Hoda Hashemi’s 2024 dissertation titled “Sensory-based Strategies in School Settings: Frequency, Duration, Outcomes, and Teachers’ Perception on Their Efficacy for Students on the Autism Spectrum” provides a comprehensive look into how sensory-based strategies are applied in school settings. The research explores the frequency and duration of sensory interventions, their outcomes in reducing disruptive behaviors, and how teachers perceive their effectiveness. It also reveals some of the challenges and gaps in current practice, particularly the limited empirical evidence supporting certain widely used strategies.
The Growing Role of Sensory-Based Strategies in Special Education
Students with ASD often exhibit sensory processing issues, leading to behaviors that can be disruptive or interfere with their learning and social interactions. These behaviors may include fidgeting, flapping hands, vocalizing repetitively, or seeking sensory input through touch or movement. Sensory-based strategies are designed to help students manage these behaviors by addressing their underlying sensory needs.
Hashemi’s research brings attention to the varied types of sensory-based interventions used in schools. These range from simple tools like fidget toys to more structured activities such as using therapy balls for seating or incorporating weighted vests for deep pressure input. The rationale behind these interventions is that by providing sensory stimulation, students are better able to regulate their emotions, focus on tasks, and participate in classroom activities without being overwhelmed or distracted by sensory input.
Frequency and Duration of Sensory-Based Strategies
One of the key findings of Hashemi’s study was the frequency and duration with which sensory-based strategies are employed in school settings. Teachers reported using sensory interventions regularly throughout the school day, often in response to specific student behaviors. For example, alternative seating, such as therapy balls, was used during academic work periods to help students maintain focus. Similarly, sensory breaks, where students could engage with sensory toys or participate in movement activities, were incorporated to give students an opportunity to self-regulate.
The duration of these interventions varied. Short sensory breaks, lasting only a few minutes, were used to help students recalibrate when they became overstimulated or disengaged. In contrast, longer interventions—such as sitting on a therapy ball during a 15-minute classroom task—were used to provide continuous sensory input that could help students maintain their focus for extended periods.
Overall, the study found that the frequency of sensory interventions was highly individualized, depending on the student’s sensory profile and behavior needs. Some students required more frequent and longer interventions to maintain engagement, while others benefited from occasional sensory breaks or short bursts of sensory input.
Outcomes of Sensory-Based Strategies: Mixed Results
A central focus of Hashemi’s research was determining whether sensory-based strategies effectively reduce interfering behaviors and promote on-task behavior. The results were mixed, reflecting both successes and limitations of these interventions.
Positive Outcomes
For some students, sensory-based interventions resulted in noticeable improvements in behavior and engagement. For example, alternative seating options like therapy balls allowed students to engage in slight movements while staying seated, which helped them focus on academic tasks. Teachers observed that students who used therapy balls often demonstrated improved posture, increased engagement, and better task completion rates compared to when they used traditional seating.
In addition, certain deep-pressure interventions, such as weighted vests, appeared to have calming effects for some students, particularly those who exhibited anxiety or hyperactivity. Deep pressure input has been shown to help students regulate their sensory systems, reducing the need for sensory-seeking or sensory-avoiding behaviors, such as excessive fidgeting or avoiding participation in group activities.
Challenges and Limitations
Despite these positive outcomes, Hashemi’s research also revealed that many sensory-based strategies did not consistently lead to reductions in interfering behaviors. For instance, while weighted vests are commonly believed to provide calming sensory input, the study found that their effectiveness was inconsistent. In some cases, students wearing weighted vests continued to exhibit off-task behaviors or disruptive movements, suggesting that the intervention may not work universally for all students.
Additionally, interventions like fidget toys and alternative lighting—where dimmed or colored lights were used to create a sensory-friendly environment—did not always lead to the desired behavioral improvements. Teachers reported that while some students found these tools helpful, others were either indifferent or became distracted by them, highlighting the need for careful selection of interventions based on each student’s sensory preferences and needs.
Teachers’ Perception of the Efficacy of Sensory-Based Strategies
A crucial aspect of Hashemi’s dissertation was understanding how teachers perceive the efficacy of sensory-based interventions. Teachers, as the primary implementers of these strategies, play a vital role in determining which tools and techniques are used in the classroom.
General Support with Reservations
The majority of teachers expressed general support for sensory-based strategies, acknowledging their potential to help students manage sensory challenges and stay engaged in learning. Many teachers shared anecdotal evidence of students who showed improvements in behavior or academic performance when using sensory tools like fidgets or therapy balls. Teachers also noted that sensory breaks—where students could leave their desks to engage in movement activities—often helped reset students’ attention and reduce disruptive behaviors.
However, despite their positive attitudes, many teachers expressed reservations about the overall efficacy of these strategies. They recognized that sensory-based interventions were not a “one-size-fits-all” solution and that the same strategy could produce different outcomes depending on the student. Teachers emphasized the need for individualized approaches, as a tool that worked well for one student could have little to no effect on another.
Lack of Clear Guidelines and Training
Another major concern among teachers was the lack of clear guidelines and training on how to effectively implement sensory-based strategies. Many teachers reported feeling uncertain about how to choose the right interventions for their students and how to measure the effectiveness of those interventions. Hashemi’s research highlighted this gap, noting that while sensory-based strategies are widely used, there is often little professional development provided to teachers on how to use them effectively.
Teachers also expressed the need for more empirical evidence to support the use of these strategies. While some interventions, such as Ayres Sensory Integration (ASI), have been identified as evidence-based practices, others—like the use of weighted vests or fidget toys—lack consistent support in the research literature. This lack of definitive evidence made some teachers hesitant to fully rely on sensory-based strategies as a primary means of managing student behavior.
Challenges in Implementation
In addition to concerns about training and evidence, Hashemi’s research identified several practical challenges in implementing sensory-based strategies in school settings. One of the most significant challenges was balancing the use of these strategies with the demands of academic instruction. Teachers reported that it was difficult to provide individualized sensory interventions in a busy classroom, especially when managing multiple students with different sensory needs.
Another challenge was the time and resources required to implement certain sensory-based interventions. For example, strategies like using therapy balls or alternative lighting often required specialized equipment, which was not always readily available in schools. Additionally, the need for consistent monitoring and adjustment of interventions added to teachers’ workloads, making it difficult to maintain these strategies over the long term.
Recommendations for Educators
Despite the challenges and mixed outcomes, Hashemi’s research offers several practical recommendations for educators looking to incorporate sensory-based strategies into their classrooms.
- Conduct Functional Behavior Assessments (FBAs): One of the key recommendations from the study is the importance of conducting FBAs to understand the underlying causes of a student’s interfering behaviors. By identifying whether a behavior is sensory-seeking or sensory-avoiding, teachers can tailor interventions more effectively.
- Use Alternative Seating to Promote Engagement: Hashemi suggests that alternative seating options, such as therapy balls or sensory cushions, can be a simple yet effective way to help students self-regulate and stay focused on tasks. These tools allow students to engage in small movements that provide sensory input without being disruptive to the rest of the class.
- Incorporate Regular Sensory Breaks: Scheduling sensory breaks throughout the day can provide students with opportunities to engage in movement or sensory activities that help them reset and refocus. These breaks can be as simple as walking around the classroom or using a fidget toy for a few minutes.
- Seek Professional Development: Educators should advocate for more professional development opportunities related to sensory-based strategies. Training on how to select, implement, and evaluate sensory interventions can help teachers feel more confident in using these tools in their classrooms.
- Focus on Individualization: Given the variability in how students respond to sensory-based strategies, it is essential to individualize interventions based on each student’s sensory profile. Teachers should be prepared to experiment with different tools and techniques to find what works best for each student.
Conclusion: Bridging the Gap Between Research and Practice
Hoda Hashemi’s 2024 dissertation provides valuable insights into the use of sensory-based strategies in school settings, highlighting both their potential benefits and limitations. While these strategies can help students with ASD manage their sensory challenges and improve on-task behavior, they are not a universal solution. Teachers must approach sensory-based interventions with an understanding of each student’s unique needs and behaviors, using data-driven methods to assess their effectiveness.
The research also underscores the need for more empirical studies to support the use of sensory-based strategies in schools, as well as the importance of providing teachers with the training and resources they need to implement these strategies effectively. By bridging the gap between research and practice, educators can create more supportive and sensory-friendly environments that enhance learning for all students.
