Reading achievement scores for adolescents with disabilities are markedly lower than the scores of adolescents without disabilities. For example, 62% of students with disabilities read "below" the basic level on the NAEP Reading assessment, compared to 19% of their nondisabled peers. This achievement gap has been a continuing challenge…

Objective: Our aim was to evaluate a health education programme (TBIoptions: Promoting Knowledge) designed to increase public awareness and understanding about traumatic brain injury (TBI) through in-person (classroom) and computer-based (electronic) learning environments. Design: We used a pre-post survey design with randomization of participants…

We have two aims here. Our first is to articulate what gains may be made by students who engage in our course to determine what exactly is gained by students who participate in such experiences. We believe such courses have educational value, but needed to find a way to articulate our course's success in helping students meet our stated learning…

This study addressed whether prior successes with educational interventions grounded in the theory of successful intelligence could be replicated on a larger scale as the primary basis for instruction in language arts, mathematics, and science. A total of 7,702 4th-grade students in the United States, drawn from 223 elementary school classrooms in…

Background: Cluster-randomized experiments that assign intact groups such as schools or school districts to treatment conditions are increasingly common in educational research. Such experiments are inherently multilevel designs whose sensitivity (statistical power and precision of estimates) depends on the variance decomposition across levels.…
