Computer- and video-based instruction of food-preparation skills: acquisition, generalization, and maintenance.

The purpose of this study was to evaluate the effects of a computer-based video instruction (CBVI) program to teach life skills. Three middle school-aged students with intellectual disabilities were taught how to make a sandwich, use a microwave, and set the table with a CBVI software package. A multiple probe across behaviors design was used to evaluate for a functional relation between the software and skill acquisition. All students increased the percentage of steps completed in the correct order after receiving CBVI. During maintenance probes, the performance of all students deteriorated; after a single review session with CBVI, all students regained previous levels of performance, tentatively indicating a role of CBVI as a tool for reviewing previously mastered material. Results are discussed in terms of the use of CBVI for providing students sufficient learning trials on tasks that require the use of consumable products (e.g., food).
