Two methods of assessing student learning of a hands-on instructional unit are compared. One method involves manipulation of concrete materials, and the other method involves manipulation of icons on a computer to solve an electric circuits problem. Sixth-grade students in an inquiry-based science program completed both assignments. (LZ)

The Meyerhoff Program enhances the success of talented African American science and engineering by focusing on knowledge and skills, motivation and support, monitoring and advising, and academic and social integration. Outcome data show that Meyerhoff students (n=69) achieved GPAs significantly higher than a comparison sample. (Author/SYB)

A previously proposed structural model of the theory of educational productivity of H. J. Walberg was tested for science achievement and attitude with a national probability sample of 2,535 tenth graders from the Longitudinal Study of American Youth. Results support a mediated effects representation of the productivity model. (SLD)

Firm evidence shows that formative assessment is an essential ingredient of classroom work and that its development can raise achievement standards. Achieving this goal demands a four-point scheme for teacher development: learning from development, a slow, yet steady dissemination process, reduction of obstacles, and substantive research efforts.…

Natural experiments explored the effects of attending public Philadelphia K-to-8 schools or public middle schools on eighth- and ninth-grade achievement. Found that students attending K-8 schools had higher reading, mathematics, and science achievement than students attending middle schools serving similar communities. Suggested that number of…

This study of Third International Mathematics and Science Study results addresses the issue of resource availability in rural and urban Australian schools, considering student attitudes toward math and science and career aspirations. Rural schools are more adequately resourced than urban ones. Students' attitudes and aspirations positively affect…

A recent study indicated students in the United States do not understand basic math and science as well as students in other countries, and will not be prepared for decision making in a largely scientific and technological world. Suggests ways for parents to emphasize science at school, at home, on school field trips, with science fairs, and with…

This article reports the development and application of two instruments for assessing science teachers' pedagogical knowledge in the context of teaching higher-order thinking: a Likert-type research instrument, and an instrument that analyzes classroom observations. The rationale for developing these instruments and their main categories is…

The development of valid and reliable instruments for attitudes' measurement has been proven crucial for the quality of research. This study is dealing with the development and validation of an attitude toward chemistry instrument. By using this instrument, 11th grade Greek students' attitudes regarding the difficulty, the interest, the usefulness…

The present study makes use of the capabilities of computerized environments to enable simultaneous display of molecular representations that correspond to observations at the macroscopic level. This study questions the immediate and long-term effects of using a multimedia instructional unit that integrates the macroscopic, symbolic, and molecular…

The purpose of this study was twofold. One purpose was to identify the locally negotiated literate practices that defined ways of communicating information and knowledge across the curriculum in a fourth/fifth grade classroom. Through an ethnographic and sociolinguistic set of analyses, this investigation illustrated how the teacher worked to…

This review examines twenty years of research (1985-2005) on African-American students in science education. This analysis identified three types of research studies on African-Americans. First, a series of studies provided status reports of African-American students' performance in science. Second, a series of studies highlighted cultural…

The majority of undergraduates lack advanced reasoning patterns, which are necessary for significant achievement in college science courses. The purpose of this paper is to review the studies of various instructional practices in introductory college biology courses that claim to develop reasoning. Most of these were non-traditional,…

We examine the effects of family structures and processes on student achievement in Hong Kong. Specifically, we show that the negative effects of single parenthood in past studies are not universal. In Hong Kong, 4,405 15-year-old students completed a questionnaire, and tests in reading, mathematics and science. We analysed the data using…

The purpose of this article is to suggest ways of using research on children's reasoning and learning to elaborate on existing national standards and to improve large-scale and classroom assessments. The authors suggest that "learning progressions"--descriptions of successively more sophisticated ways of reasoning within a content domain based on…
