Self-monitoring is regarded throughout the literature as an effective classroom intervention. Researchers have used self-monitoring interventions to improve school-related behavior of students with varying disabilities across a variety of settings. Although research supports the use of self-monitoring, traditional self-monitoring techniques may be unappealing to students and inefficient for use in the classroom. Cell phones hold great promise for increasing the acceptability and efficiency of self-monitoring interventions. The purpose of this article is to describe a self-monitoring technique that incorporates cell phones and text messages. We provide step-by-step instructions for setting up and implementing CellF-Monitoring in a classroom.
