Comparison studies conducted to determine which instructional interventions are most efficient for teaching discrete behaviors to individuals with disabilities are potentially valuable, although some threats to internal validity may be more likely in these studies. Studies included in this review typically met common internal validity standards,…

Inappropriate behavior on school buses is a safety issue that concerns students, parents, and educators. There is potential for traffic-related injury, and the limited adult supervision on school buses often facilitates bullying and other infractions. This review identified peer-reviewed articles and dissertations evaluating behavioral…

This commentary argues that the study reported in EC 605 442, which indicated long-term gains for children with autism who experienced intensive behavioral intervention as preschoolers, needs to be replicated to be convincing, especially given the problem of nonrandom assignment of experimental and control groups.

The focus of this review is on observational measures of pupil classroom behaviors. Two issues are raised in connection with these measures. First, there is a survey of the types of observation schedules employed in recent classroom intervention research. Second, there is an evaluation of the validity of these behavioral measures. That evaluation…

This commentary on EC 605 442, which indicated long-term gains for children with autism who experienced intensive behavioral intervention as preschoolers, questions the magnitude of the student changes and their significance, because of concerns about the representativeness and comparability of the sample group and the failure to measure skills…

This commentary on a study reported in EC 605 442, which indicated long-term gains for children with autism who experienced intensive behavioral intervention as preschoolers, criticizes the outcome measures used in the study as inadequate in determining whether normal functioning in cognitive, emotional, and adaptive functioning was achieved as…

This commentary on EC 605 442, which indicated long-term gains for children with autism who experienced intensive behavioral intervention as preschoolers, emphasizes the need for replication. The replication study should use random assignment to experimental and control groups, a larger sample of cases, standard diagnostic instruments to delineate…
