We examined the effectiveness of a tactile self-monitoring prompt to increase on-task behaviors among 3 elementary-aged students in a special education classroom. Students were taught to self-monitor their attention by using the MotivAider (MotivAider, 2000), an electronic beeper that vibrates to provide a tactile cue to self-monitor. An ABAB reversal design was used for each participant. Results indicated that upon implementation of the self-monitoring intervention, students increased on-task behavior from a mean of 55% to more than 90% of the intervals observed. Additionally, teachers and students provided high ratings of treatment acceptability of this selfmonitoring intervention. Limitations, implications, and future directions of these findings are discussed.
