Task interspersal is an academic material modification procedure implemented by adding a sequence of brief tasks prior to more difficult academic tasks. The purpose of this study was to investigate the effects of the interspersal procedure under both time-based (i.e., time allotted to complete task held constant) and task-based (i.e., number of…

Behaviors characteristic of attention deficit/hyperactivity disorder (ADHD) often interfere with students' and their classmates' learning, and interventions targeting these behaviors may be particularly important in schools. This article reviews studies in which researchers manipulated environmental stimulation during task presentation…

Transitions are critical times for both teachers and students. Efficient between-task and within-task transitions can greatly improve academic learning time. The purpose of this article was to review one intervention, high-probability (high-p) task sequences, as a method to promote more effective transitions. High-p sequences involve presenting a…

Basic fact acquisition is an important component for developing higher-order math skills. However, getting students with a history of academic noncompliance to engage in activities related to skills acquisition can be difficult. Prior research demonstrates that engagement increases when nonpreferred activities are preceded by a series of brief…

Two studies evaluated the effects of within-task and competing visual stimulation on the mathematics performance and behavior of 17 children (ages 8-14) with attention deficit hyperactivity disorder. Results indicate the same high within-task simulation that enhanced student performance and reduced off-task behavior was effective only when…
