The study involved implementing and evaluating activities that actively engage students in the process of gathering, processing and analyzing data derived from human body measurements, with students using their prior knowledge acquired in science, mathematics, and computer classes to interpret this information. In the classroom activities…

This paper reports on an ongoing 5-year study on practices and policies that improve postschool outcomes for students with disabilities in significantly restructured high schools. Four high schools with strong internal accountability measures are subjects of an intensive longitudinal study. The schools are in both urban and smaller communities in…

High schools are increasingly expected to use data for improvement and to provide evidence that programs and instructional practices are preparing all students to develop essential knowledge and skills. This publication describes how schools can develop the capacity to analyze and use data as a core component of improving secondary schools using…
