The purpose of this study was to develop, scale, and validate assessments in engineering, science, and mathematics with grade appropriate items that were sensitive to the curriculum developed by teachers. The use of item response theory to assess item functioning was a focus of the study. The work is part of a larger project focused on increasing…

This longitudinal, five-year study of teachers and students who had participated in a systemic reform program in science explored if (1) teacher change in practice realized during a three-year program is sustained one, two, and three years following the program, (2) student performance on state science assessments two years following studying with…

The purpose of this article is to focus on the development and refinement of a science instructional design program arguing for the feasibility and usability of integrated reading and science instruction as implemented in third- and fourth-grade science classrooms to meet the learning needs of diverse learners. These instructional components are…

Studies on science course improvement projects are synthesized, with reactions from several professional organizations. Other reports from the mid-1980s are noted. A brief summary of research findings is provided, with a longer discussion on the impetus for change, the conditions needed for change, and who decides. (MNS)
