Total group contingencies, a variation of interdependent group contingencies, provide educators with an efficient and effective mechanism to improve social behavior and increase academic skills. Their utility has not been examined in small educational groups. This is unfortunate as supplemental instruction frequently is delivered in small group settings, and problem behavior may have a deleterious effect on learning. This study evaluated effects of a positive reinforcement total group contingency implemented by instructional assistants across five small groups of kindergarten students receiving supplemental literacy instruction. Results indicated reductions in student problem behavior, increases in adult provision of specific praise statements, and increases in opportunities to respond to academic instruction. Although the intervention focused on student social behavior, we also documented improved fidelity of implementation of the literacy instruction following training and implementation of the total group criterion intervention. The implications for implementing total group contingencies during small group instruction are discussed.
