This study investigated the effectiveness of a treatment package that included
video technology (e.g., video modeling and video prompting) to teach three selfhelp skills (e.g., cleaning sunglasses, putting on a wrist watch, and zipping a
jacket) to three elementary school students with mental disabilities in a small
group setting. Using a constant time delay (CTD) procedure, observers measured
the percentage of steps of the task analyses performed correctly before and
after a video model prompt. A multiple probe design across behaviors, replicated
across participants, demonstrated experimental control. The results indicate
that an instructional package that includes video technology can be an effective
method for teaching self-help skills to students with mental disabilities.
