The study investigated the effectiveness of self-modeling as a treatment to
increase on-task behavior. A multiple baseline design across 3 students wa
s employed to determine the treatment effects. In addition, classroom peers
' on-task behavior was employed as comparison data. The results indicated i
mmediate, substantial, and durable changes in students' on-task behavior th
at generalized across academic settings. The 3 students evidenced an increa
se of on-task behavior from an average of 33% of the intervals observed at
baseline to 86% during treatment. At 6- and 8-week follow-up, the students'
percentages of on-task behavior was essentially indistinguishable from the
ir classroom peers. Consumer data indicated that the teachers and students
were satisfied with the procedure. (C) 2000 John Wiley & Sons, Inc.
