This study examined the effect of using a remote device, a Clicker, on the on-task behavior of middle school students with behavior problems. Five students with behavior problems participated in the study. A single-subject research design with ABAB (phase A: baseline 1, phase B: intervention 1, phase A: baseline 2, phase B: intervention 2) phases was used. During the baseline, students' on-task behavior was recorded in both language and math classes. During the intervention, students were provided a Clicker to answer questions. The Clicker was withdrawn after 5 days of intervention, then returned to the students following the same procedures in the previous intervention. Results showed that students' on-task behavior increased as well as their academic performance when Clickers were applied. A follow-up interview indicated that students were satisfied with the Clicker and preferred to use this device in class.
