Reviews findings from cognitive studies that are relevant to physics instruction. Organizes the information into four broad principles: (1) pattern construction; (2) changing mental models through assimilation; (3) extending mental models through accommodation; and (4) the individuality of mental models. (DDR)

Describes several demonstrations that feature interaction of light with soap bubbles. Includes directions about how to produce a long-lasting stationary soap bubble with an easily changeable size and describes the interaction of white light with the bubble. (DDR)

Explains why transparency film demonstrates biaxial optical properties. Provides detailed descriptions of the procedure and equipment needed for large-scale optics demonstrations of the polarization interference pattern produced by biaxial crystals. (DDR)

Describes a study that compares the performance of introductory physics students on two examination problems. One problem is qualitative and similar to those used in an inquiry approach. The second problem is a typical quantitative problem. Those students enrolled in the inquiry-based introductory course performed significantly better than those…

Describes the development and analysis of the Test of Understanding Graphs in Kinematics (TUG-K) and reports the results of a study aimed at uncovering student problems with interpreting kinematics graphs. Proposes a model for creating multiple choice tests which can be used as diagnostic tools. Contains 34 references. (DDR)

Describes a technique that uses a helium neon laser, a steel rule, a wooden rule, and a piece of paper to measure the diameter of a hair using the diffraction of light. Details on technique, mathematics, and sources of error are provided. (DDR)

Explains the philosophy that forms the basis of a high school physical science course based on astronomy and the activity-based textbook that accompanies it. Cites specific examples of misconceptions related to astronomy and recommends various diagnostic and concept change strategies. (DDR)

Discusses the gender gap in science classrooms and how it relates to the confidence and competence of female students in astronomy. Cites specific instructional techniques that are helpful in increasing the participation of females in science and specifically recommends involving students in research. (DDR)

Presents two views about the future of astronomy. Explains that government budget cuts and an oversupply of young scientists have decimated the employment prospects. Encourages students to train for a wide variety of careers and to become entrepreneurs who bring technologies to the consumer. (DDR)

Describes five astronomy education projects implemented by the Harvard-Smithsonian Center for Astrophysics Science Education Department and funded by the National Science Foundation. Project efforts have concentrated in three major areas: (1) curriculum development; (2) teacher support; and (3) classroom technology. (DDR)

Describes and evaluates an attempt to teach about Brownian motion and to simultaneously draw out lessons about the nature of science. Outlines the learning tasks, summarizes and analyzes student responses from a questionnaire. (DDR)

Describes an investigation with the primary purpose of allowing students to generate and interpret a pressure/volume diagram of a Stirling engine. Explains how the Stirling engine can be used to demonstrate the principles of operation of a refrigerator and a heat pump. (DDR)

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)
