Effects of Multimedia, Computer-Based Instruction on Grocery Shopping Fluency

Abstract

This study examined the effectiveness of a multimedia program (i.e., interactive computer program, video captions, and still photographs) to increase the fluency of three students with intellectual disabilities to grocery shop. A multiple probe design across participants was used to evaluate the effectiveness of the multimedia program. Instruction, using a constant time delay procedure, occurred through simulations on the computer using video captions and still photographs. Video captions were made in a subjective point of view in which students viewed the sequence of steps for completing the task at the student's eye level as if he/she were performing the skill. The 12 items on the grocery list were arranged by categories (e.g., dairy, canned foods) and fluency of skills was assessed through shopping at a local grocery store. Results indicate that the multimedia program alone was effective in increasing the fluency in which students were able to read aisle signs and locate items without the use of an adaptive grocery shopping list.
