Practitioner-Implemented Video Prompting on Vocational Skills of Students With Significant Intellectual and Developmental Disabilities

Video prompting (VP) is an evidence-based practice, but few studies have included teachers and paraeducators as implementers. We adopted one of the single-case designs (multiple probe design) to evaluate the effectiveness of teacher and paraeducator-implemented VP on vocational skills for four high school students with significant intellectual and developmental disabilities. Experimental effects were demonstrated for all four students, but only two students met the mastery criterion. Individualized adaptations (i.e., priming, more frequent reinforcement) enabled two students to make further progress. The two students who met the mastery criterion maintained their performance after 2 weeks. These findings add to growing evidence that teachers and practitioners can effectively implement VP and suggest that individualized adaptations may be needed for some students with significant disabilities.

This study evaluated the effectiveness of teacher and paraeducator-implemented VP on vocational skills for high school students with intellectual and developmental disabilities. The results showed experimental effects for all four students, with two students meeting the mastery criterion. Individualized adaptations enabled two students to make further progress, and the two students who met the criterion maintained their performance after 2 weeks. These findings contribute to the evidence that teachers and practitioners can effectively implement VP and highlight the need for individualized adaptations for students with significant disabilities.
