Abstract

The purpose of this study was to compare the effects of randomized and non-randomized criteria of work completion and accuracy within an interdependent group contingency (Good Classwork Game). Four elementary/middle school students referred for off-task/disruptive behavior and work incompletion in mathematics, their peers, and the teachers participated in this study. Each class was divided into two teams and winners were announced contingent upon achieving non-randomized or randomized criteria. The team(s) with averages equal to or more than the criteria won the game and gained access to privileges. The effects of the intervention were assessed using a cross-over phase change (ABCB and ACBC) design. No differences in work productivity were noted across different phases, indicating that both criteria were equally effective in increasing work completion.
