Argues for an emphatic role for theory in everyday science teaching. Contrasts science's confidence in its theories with those of other sorts which students encounter in their everyday lives. Discusses common denominator science teaching in which teachers teach science in units based on different sciences. (DDR)

Discusses the decline of the number of students wishing to continue with physics in many countries. Brings together the relevant findings of two research projects and considers the effect of changes in the school curriculum. Contains 18 references. (DDR)

Investigates gender issues in Israeli advanced placement physics classes. Analyzes matriculation exam scores from approximately 400 high schools over 12 years. Conducts semi-constructed interviews with 50 advanced placement physics students (25 girls and 25 boys). Discusses changes in the ratio of girls, performance, and factors that are…

Discusses Einstein's special relativity theory and some of the developmental mathematics involved. Presents motivational classroom materials used in discussing relative-motion problems, evaluating a radical expression, graphing with asymptotes, interpreting a graph, studying variation, and solving literal and radical equations. (KHR)

Investigates students' ideas about gravity beyond the earth's surface. Presents a lesson plan designed to help students understand that gravity can act beyond Earth's atmosphere. Also helps students gain a more adequate intuitive understanding of how natural and artificial satellites stay in orbit. Reports that this strategy changed some students'…

Describes a practicum-based course for teaching Applied Arts students about color that considered students' previous ideas about color when devising experiments and assignments. The conceptual content was chosen to integrate scientific, technical, and perceptual aspects of color. Results of student evaluations and implications for classroom…

Highlights the need to make the undergraduate physics laboratory more exciting and commensurate with the time assigned for it in the curriculum. Suggests establishing a model undergraduate physics laboratory at one place then reproducing it in five places for a massive reorientation program for teachers. Contains brief outlines of 30 experiments…

Describes a simple computer-interfaced experiment for recording the response of an RC network to direct current and square input signals. Undertakes a systematic qualitative and quantitative analysis for the high- and low-pass configurations. Suggests some examples of open-ended problems to develop a feel for circuit behavior. (AIM)

A study compared 17 preschoolers, 18 7-year-olds, 17 10-year-olds, and 21 children with autism and 21 age-matched controls. Children with autism preferred to employ physical causality when reasoning about novel physical and psychological events. A multiple-choice task confirmed their impairment in intuitive psychology while highlighting superior…

Presents and analyzes a detailed example of classroom dialogues such as peer instruction, and describes the format, procedures, and curricular materials required for creating the desired lecture-room environment. (Contains 94 references.) (Author/YDS)

Identifies communication difficulties between students and students and instructors as important sources of barriers to achieving high-quality student practice. Proposes some strategies to address communication difficulties in the context of small-group, in-class problem solving. (Contains 36 references.) (Author/YDS)

Describes a series of activities exploring Leonardo da Vinci's tree theory that are designed to strengthen 8th grade students' data collection and problem solving skills in physical science classes. (KHR)

Reports the results of an investigation into factors associated with variations in students' ability to achieve conceptual learning gains in a physics course that employs interactive-engagement methods. Explores the correlation between students' normalized learning gains and their initial level of physics concept knowledge, pre-instruction…

Instructions for the construction of this instrument and its use are presented. The use of common materials is emphasized. (CW)

Discussed is the teaching of physics with an emphasis on the learning of concepts before problem solving. Examples of this approach are provided. (CW)
