Examining the Effectiveness of a Multimedia Video on Pedestrian Safety With Postsecondary Individuals With Intellectual Disabilities

Abstract

Prior research suggests that the use of multimedia instruction along with video modeling increases the ability of individuals with intellectual disability (ID) to independently complete tasks. However, the previous research has not always included instruction of the underlying vocabulary, nor has it always resulted in skill maintenance. The purpose of the current study was to compare the effectiveness of multimedia instruction using video modeling to teach pedestrian safety signs to participants with ID to support skills needed for community. The effectiveness of the multimedia intervention was measured using a randomized control trial utilizing a pre-/posttest design. Participants’ knowledge grew significantly from pre-to posttest, and there were no significant differences between the groups. Current results are similar to prior research findings indicating multimedia instruction is effective in teaching skill acquisition. We discuss practical implications of these findings as well as future research on teaching pedestrian safety to postsecondary individuals with ID.
