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…

Within the field of science education, there remains little agreement as to the definition and characteristics of classroom inquiry. The emerging emphasis on scientific practices in science education reform discourse is underpinned by a need to better articulate the constituent elements of inquiry-based science. While a small number of…

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…

This case study reviewed the collaborative efforts of university engineers, teacher educators, and middle school teachers to advance sixth- and seventh-grade students' learning through a series of project-based engineering activities. This two-year project enriched regular school curricula by introducing real-world applications of science and…

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)

Control group students (receiving descriptive, non-inquiry science) and experimental group students (using Science Curriculum Improvement Study-SCIS "Interaction and Systems" materials) were later combined in grade 4 for instruction with SCIS "Subsystems and Variables" materials. Results show similar difficulties in learning…

Determines if elementary teachers' (N=138) understanding of SCIS concepts and teaching strategies change as a result of a televised inservice program using confidence levels as a criterion for understanding. Findings indicate that an inservice program consisting of televised sessions significantly improves teachers' understanding of SCIS concepts…

Summarizes findings of seven studies dealing with how teacher behavior affects student performance in activity-centered science classrooms at the elementary and junior high school levels. Concludes that activity-centered classrooms encourage student creativity in problem solving, student independence, and help low ability students overcome initial…

For two summers, week-long residential mathematics programs were held for high school women, with the primary goal of encouraging them to continue their study of mathematics. The activities were designed to rekindle their excitement about mathematics and to support the idea that women should learn advanced mathematics. This paper reports the…
