Abstract:
The efficacy of a group-evaluation system was examined, with a reversal design, in two classes of students with disabilities. The results suggested that a group-evaluation system was effective in decreasing the inappropriate verbalizations of both groups. Student satisfaction data revealed that the students in both groups had positive reactions to the system. Factors contributing to the success of the intervention as well as suggestions for its implementation are discussed.
