Abstract
A multiple baseline design across three third-grade boys was used to determine the effectiveness of self-monitoring as an intervention tool in the classroom setting. The differential effectiveness of self-monitoring the correctness of answers to arithmetic problems and of self-monitoring on-task behavior was determined by an alternating-treatments design for each boy. Self-monitoring academic accuracy or on-task behavior produced comparable effects. Self-monitoring increased on-task behavior for all three subjects. Self-monitoring increased the rate of completion of arithmetic problems for two of the three subjects. Self-monitoring did not affect academic accuracy in a consistent manner. These results are discussed in light of the instruction and motivational aspects of self-monitoring.
