Self-management procedures have been used in school settings to successfully reduce problem behaviors, as well as to reinforce appropriate behavior. A multiple-baseline across participants design was applied in this study to evaluate the effects of using a self-management procedure to enhance the classroom preparation skills of secondary school…
