Teachers are o�en ill-prepared to manage classrooms in urban schools. In the present study, an empirically-based behavioral management strategy, the Good Behavior Game (Game), was investigated. The effects of the Game on student behavior and teacher response statements, including praise, were examined. A teacher with 22 students in a first grade classroom of an urban elementary school participated in implementation of the Game. Using a withdrawal design, results showed that student on-task behavior increased while disruptive behavior decreased, replicating previous findings. The number of teacher praise statements remained at near zero levels across conditions. Frequency of teacher neutral and negative statements varied with the level of student disruptive behavior. Teacher praise and limitations are discussed.

This study investigated students' allocation of responding as a function of task difficulty and type of reinforcement contingency (i.e., accuracy based or time based). Four regular education fourth-grade students were presented with two identical stacks of easy and then difficult math worksheets using a reversal design. Regardless of condition, completing problems from each stack of worksheets was reinforced according to a different contingency; one required correct completion of math problems (accuracy based) and one required on-task behavior (time based). Results suggested that 3 of the 4 students preferred the accuracy-based contingency when given easy material and the time-based contingency when given difficult material. One student allocated more responding to the accuracy-based contingency when given easy problems but did not show a clear preference for either contingency with difficult problems. The implications of these findings for designing reinforcement-based programs for tasks of varying difficulty are discussed.

Probabilistic reward has been shown to affect children's choice behavior in game-like activities. We examined the effects of a lottery system containing progressively lower exchange ratios on children's completion of math problems. Two of the 3 children completed problems above baseline levels until the chance of exchange dropped to 25%. This study describes a potentially useful method for examining reinforcement schedules in applied settings and extends previous research on probabilities of reinforcement.
