This study investigated the impact of a brief teacher training combined with use of a MotivAider that sought to simultaneously manipulate rate of opportunity to respond and positive feedback on students' on-task behavior during a classroom activity. The goal of the training was to increase the percentage of time the learner stayed on task during the class activity. Three elementary teacher-student dyads took part in this study. An A-B-A-B withdrawal design was employed to evaluate the function of relation between independent and dependent variables. Results showed low effectiveness of brief training and MotivAider as a strategy of increasing teachers providing the opportunity to respond, positive performance feedback, and student on-task behavior. Although changes in teacher behavior were observed, a functional relation was not established. There were several limitations identified in this study related to data collection process, IOA results, and beginning baseline and intervention phases. Suggestions for future research are provided.
