Disparities in gifted representation across demographic subgroups represents a large and persistent challenge in U.S. public schools. In this paper, we measure the impacts of a school-wide curricular intervention designed to address such disparities. We implemented Nurturing for a Bright Tomorrow (NBT) as a cluster randomized trial across…

At institutional, academic and student levels, resistance manifests itself in a variety of forms, at best supporting a critical culture and at worst creating…

This study investigates, through an experimental design, the effectiveness of a professional development program on teacher knowledge and practices and on student learning. The program consisted of a series of video-based modules designed to respond to needs of U.S. teachers, as highlighted by findings from the 1999 Third International Mathematics…

A theory-driven approach to evaluation (TDE) emphasizes the development and empirical testing of conceptual models to understand the processes and mechanisms through which programs achieve their intended goals. However, most reported applications of TDE are limited to large-scale experimental/quasi-experimental program evaluation designs. Very few…

This paper addresses the question: How does implementation influence the effectiveness of mandatory welfare-to-work programs? Data from three large-scale, multi-site random assignment experiments were pooled; quantitative measures of program implementation were constructed; and multilevel statistical modeling was used to examine the relationship…

This paper describes the research strategies employed in the Dutch Technology Enriched Schools (TES) project, which was initiated in 1987 to introduce computers into secondary education, to encourage extensive and intensive use of computers in a small number of secondary schools, and to study the effects of computer use on the classroom, the…
