Evaluating a computer flash-card sight-word recognition intervention with self-determined response intervals in elementary students with intellectual disability.

A concurrent multiple-baseline across-tasks design was used to evaluate the effectiveness of a computer flash-card sight-word recognition intervention with elementary-school students with intellectual disability. This intervention allowed the participants to self-determine each response interval and resulted in both participants acquiring previously unknown words across all word sets. Discussion focuses on the need to evaluate and compare computer flash-card sight-word recognition interventions with fixed and self-determined response intervals across students and dependent variables, including rates of inappropriate behavior and self-determination in students with intellectual disability.

Preventing Disruptive Behavior via Classroom Management: Validating the Color Wheel System in Kindergarten Classrooms.

Evidence suggests that installing a classroom management system known as the Color Wheel reduced inappropriate behaviors and increased on-task behavior in second- and fourth-grade classrooms; however, no systematic studies of the Color Wheel had been disseminated targeting pre-school or kindergarten participants. To enhance our understanding of the Color Wheel System (CWS) as a prevention system, a multiple-baseline design was used to evaluate the effects of the Color Wheel on inappropriate vocalizations (IVs) in three general education kindergarten classrooms. Partial-interval time-sampling was used to record classwide IVs, which were operationally defined as any comment or vocal noise that was not solicited by the teacher.
