This article reports on a design-based implementation research (DBIR) project that addresses the question: "How can classrooms be supported at scale to achieve the three-dimensional learning goals of the Next Generation Science Standards?" Inherent in this question are three key design challenges: (i) "three-dimensional…

This article provides an extended, comprehensive example of how teachers, schools, districts, and external factors (e.g., parental pressure and policy mandates) shape curriculum research in the U.S. It retrospectively examines how three different middle school curriculum units were implemented and scaled-up in a large, diverse school system. The…

The construction of test items, the purposes of testing and criterion-referenced testing are topics debated by two researchers. (CP)

Physical science curriculum materials were developed for below-average students based on guidelines for science teaching. These materials were tested in three ninth and tenth grade classrooms. Results showed significant improvement in students' attitudes toward the science class and laboratory. (PS)

Author argues that education has increasingly become dominated by economic interest that can lead not to enhancing equality but to its opposite. Important ideological shifts are occurring in what education is for and in the content and control of curriculum, with an increased emphasis on making education an economic product. Author predicts a…

Summarizes major findings of the Harvard Project Physics research and evaluation activity, including data gathering techniques, descriptions of teacher characteristics, information about student responses and learning environments, and final evaluation year results. Indicates that the evaluation program is characterized by considerable research on…

Science curriculum evaluation studies (1963-1978) were examined to assess impact of innovative curricula compared with traditional curricula on student learning outcomes. Results suggest students in secondary school science courses scored moderately better than students in traditional courses on innovative and neutral tests and negligibly lower on…

This report synthesizes critical issues and questions associated with science curriculum reform for the purpose of establishing a research agenda. Section headings describing needed research are as follows: Science, Technology, and Cultural Needs; Schooling Needs; Science Education Needs; and Research in Science Education Needs. Contrasts and…

This article covers the following: (1) contrasts several perspectives on science education reform by examining recommendations for introductory science courses; (2) identifies research finding that can guide reform; (3) discusses the impact of research on national precollege curriculum reform; and (4) offers a set of recommendations to guide…

The transfer of matter and energy from one organism to another and between organisms and their physical setting is a fundamental concept in life science. Not surprisingly, this concept is common to the "Benchmarks for Science Literacy" (American Association for the Advancement of Science, [1993]), the "National Science Education Standards"…
