Which instructional approach for teaching communication and emergency procedures explicitly includes sequencing and shaping behaviors as part of its methods?

• A. Explicit instruction and systematic instruction
• B. Group discussion and reflection
• C. Modeling only
• D. Chaining and behavioral shaping

Answer: (D)

Teaching communication and emergency procedures benefits from breaking the task into a clear sequence and reinforcing progress toward the full behavior. Chaining and behavioral shaping do exactly that: chaining arranges the steps in the exact order the learner must perform, teaching each link in sequence and gradually adding links until the full skill is complete. Shaping reinforces successive approximations toward the final target, so small improvements—like looking at the device, touching it, then pressing it—are rewarded and strengthened until the complete, independent routine is achieved. This combination directly addresses both the order of actions and the gradual improvement needed for learners with severe-profound disabilities.

Other approaches don’t emphasize this step-by-step sequencing and gradual refinement as their core method. Explicit instruction and systematic instruction focus on clear, direct teaching and practiced routines, but they don’t inherently center the specific chaining of steps and progressive shaping of responses. Group discussion and reflection involve cognitive processing and social interaction rather than teaching a tangible sequence of actions. Modeling only shows the target behavior without guiding the learner through performing and reinforcing each step.
