Twelve proficient peer models without disabilities demonstrated a response chain for a targeted learning task each day and described the steps to three classmates with developmental disabilities, who observed. The peer models performed the response chains accurately and quickly and the students with disabilities acquired the response chains. (DB)

Task analysis and backward chaining were used to teach four young adults with moderate mental disabilities basic first aid skills for simulated cuts, burns, and insect bites. Following training, students were able to apply skills to a nonhandicapped peer. Maintenance probes at 1 to 18 weeks posttraining indicated mixed results. Social validation…
