Describes an experiment that uses a bottle, a cork, and a wooden match to study students' explanations of what they observe to reveal misunderstandings about pressure and to produce some incorrect interpretations such as creation of a gradient of pressure. (DDR)

Argues that graduate students who are expected to be physics instructors require training to be effective in the physics teaching environment. Describes and documents the content and fiscal components of a successful graduate student teacher-training program. (DDR)

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)

Describes an investigation that explores students' understanding of the translation, rotation, and deformation of an object. Findings illustrate that students have difficulty appreciating that these different phenomena can occur simultaneously. Discusses some implications for teaching. (DDR)

Describes a program for preparation of mathematics and science teachers that includes close connections between the students' science courses, their experiences in the schools, and learning how to teach. The program is a joint project of the faculties of science and education. (DDR)

Reports the comments of students in an A-level revision course in physics on being asked to draw a concept map for energy. Students' comments on the task were generally positive and related to their feelings about the task and their own learning. (DDR)

Summarizes the conceptual development of the notion of force historically and suggests appropriate analogies, limiting case analyses, thought experiments, and imagistic representations that can be used in high school physics classrooms. (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)

Argues that high school physics should be grounded in motivating contextual activities and connected to a philosophically and historically valid theoretical structure. Explains the large context problem approach and its effect on generating questions and problems. (DDR)

Describes an apparatus for demonstrating the second law of motion. Provides sample data and discusses the merits of this method over traditional methods of supplying a constant force. The method produces empirical best-fit lines which convincingly demonstrate that for a fixed mass, acceleration is proportional to force. (DDR)

The misconceptions related to the concepts of force and acceleration among college students are explored. Misconceptions are identified and their occurrence among a large percentage of students are observed. Provided are some implications for physics teaching and an eight-item test. (Author/YP)

Describes a simple computer-interface experiment for recording the response of an RC network to an arbitrary input excitation. The setup is used to pose a variety of open-ended investigations in network modeling by varying the initial conditions, input signal waveform, and the circuit topology. (DDR)
