Which instructional approach is supported for students with severe disabilities?

• A. Behavior analysis principles such as chaining and time delay
• B. Pure lecture without modification
• C. Unstructured play only
• D. Group discussion with no structure

Answer: (D)

Explicit, structured instruction using evidence-based behavior-analytic strategies is most appropriate for students with severe disabilities. This approach breaks skills into small, teachable steps and uses prompts (with fading) and time-delay to guide responses, along with reinforcement and ongoing data collection. By organizing learning in clear sequences and providing consistent supports, students can acquire functional skills and increase independence in a predictable, measurable way.

Other approaches fail to provide the necessary structure and supports. Pure lectures without modification don’t address the students’ communication and learning needs. Unstructured play only lacks targeted instruction and specific skill-building opportunities. Group discussions with no structure place demands on skills those learners may not have and typically do not offer the required individualized prompts, supports, and data-driven adjustments.
