Describes a unit on magnetism that utilizes hands-on activities in which students make hypotheses for discrepant behavior, discover whether a magnet attracts one object through another, measure the strength of magnets, explore levitating paper clips, and play a game dependent on magnetic attraction. (MDH)

Describes a unit of study for elementary school science on bats. Students investigate the different types of bats; examine their behavior; find facts that other students are unlikely to know; write stories about bats; and examine the concept of echolocation, the means by which bats navigate. Suggests integrated activities for mathematics…

Describes the assessment of elementary-education majors' understanding of the learning cycle. Students displayed a high frequency of alternative conceptions even though the assessment was administered after they had received instruction and extensive modeling of the learning cycle. The data provided by the test can be used to improve instruction…

Argues that by examining which concepts of a particular area of physics are fundamental and which are defined, teachers can choose concepts for investigation that progress logically and should minimize students' misconceptions and confusion. (Author)

Argues that there are only a few cases in which solubility and Ksp are related in a simple way. States that illustrations of the solubility product principle for one-to-one salts are adequate for students. Contains 23 references. (DDR)

Addresses the problem of school-sponsored assemblies featuring guest speakers who present creation science on school premises. A science teacher who spoke at a follow-up assembly established two goals: (1) to present authoritative information about evolution; and (2) to help students evaluate the creation speaker's arguments against evolution.…

Challenges vague, underconceptualized notions of teacher professional community. Findings from an exploration of two California middle-school teacher communities suggest that current models obscure significant differences in beliefs and practices. One community stresses teachers' individual rights and responsibilities; the other is driven by a…

Summarizes recent findings of empirical research in science education concerning students with disabilities. Discusses learning characteristics of disabled students, effective instructional strategies including text-based interventions and inquiry-oriented interventions, and inclusion practices. Contains 70 references. (WRM)

Reports the existence of patterns of reasoning that are common to students' conceptions in different areas of mechanics. Finds that the common frameworks between different ideas have a generality level that lies between Piaget's stage theory and the approach of alternative conceptions. Contains 30 references. (Author/WRM)

Explores African students' use of traditional Sotho cultural metaphoric reasoning in classifying everyday situations as "hot" or "cold" in order to document the extent to which such metaphoric reasoning is related to science misconceptions of heating. Finds that university students were able to distinguish between types of…

Favored explanations for the achievement gap between black and white students reflect experts' positions on the ideological spectrum, while overlooking fundamental problems with the educational delivery system. The situation of black students is not hopeless, thanks to new research that abandons whites' academic performance as the norm and…

Describes the difficulties that high school and university students have in thinking about force, identifying forces, and drawing force diagrams. Finds that students using a computer tutoring program made limited progress in learning to construct free-body diagrams because of their alternative conceptions and faulty teaching methods. Offers…

Organizes a reading of the conceptual change literature that brings into view a collection of design specifications for a conceptual change apparatus. Analyzes one such apparatus in the particulars of a science education demonstration program produced by the Harvard-Smithsonian Private Universe Project. (Contains 114 references.) (Author/WRM)

Explores the tension between subject knowledge and pedagogic content knowledge in elementary teacher education by documenting students' and inservice teachers' learning about forces in the context of floating and sinking. Describes significant features of the learning process and examines subject-specific aspects of learning by demonstrating how…

Investigates 5th and 6th grade students' learning when taught with the aid of dome and computer planetaria. Finds both planetaria equally effective with female pupils. Recommends the use of planetaria, which might enable females to catch up with males in areas that place heavy demands on spatial ability such as astronomy. (Contains 16 references.)…
