Describes how, using an overhead projector (OHP) and a transparent roll of acetate film, it is possible to demonstrate: (1) travelling waves; (2) standing waves; and (3) phase and group velocity applied to waves. The set-ups provide a way to demonstrate features which are normally difficult to visualize and understand. (JN)

Presents two simple techniques for physics demonstrations: (1) a projection lens system for oscilloscopes which uses an inexpensive surplus lens and enables the entire class to observe the screen; and (2) a polarized optical "Cheshire cat" which uses the overhead projector and Polaroid sheets. (JN)

In a program designed to help physics faculty improve their instructional techniques and curricula, their colleagues from other disciplines are taking classes alongside regular students to provide insights into reasons for learning problems. (MSE)

Discusses the purposes, advantages, and disadvantages of computer illustrated texts (CIT). Describes three separate CITs which demonstrate the variability that CITs have in terms of screen layout, programing style, and depth and range of coverage of topics in mathematical physics. (ML)

Describes a citation analysis of physics, engineering, and sociology literature which was designed to determine if there were any differences in conceptual referencing patterns. The research methodology is described and suggestions for further study are offered. (Author/LRW)

Shows that important discoveries in physical sciences cited in textbooks were made by women, although they may not be given credit for their work. Also discusses the contributions of 10 female scientists to provide role models for students. (DH)

An evaluation study of PLON, a new Dutch physics curriculum emphasizing context learning and inquiry learning, is summarized. Data from nine PLON classes (n=154) and six control classes (n=144) were used to investigate cognitive achievement, affective and attitudinal outcomes, and the classroom learning environment. (BS)

Identifies associations, programs, and resource materials which provide assistance to physics teachers. Explains the opportunities sponsored through the American Association of Physics Teachers (AAPT) and cites examples of workshops, institutes, and kits that were designed to improve physics instruction. (ML)

Provides abstracts of five papers presented at the Fourth Annual Microcomputers in Education Conference. Papers considered microcomputers in science laboratories, Apple II Plus/e computer-assisted instruction in chemistry, computer solutions for space mechanics concerns, computer applications to problem solving and hypothesis testing, and…

Describes a demonstration in which gaseous ammonia and hydrochloric acid are used to illustrate rates of diffusion (Graham's Law). Simple equipment needed for the demonstration include a long tube, rubber stoppes, and cotton. Two related demonstrations are also explained. (DH)

Determined if there are certain propositions that physics students (N=31) share with respect to a topic, to what extent is a student's knowledge on a subject idiosyncratic, and if there are different groups of students whose members share distinctive sets of propositions. Results are reported and discussed. (DH)

Analyzes data presented in a recent article (EJ 328 649) examining the relationship between A-level physics and mathematics and degree performance in engineering or physics. A grade of A in A-level physics predicted first class degree performance. (JM)

The Six Flags Over Georgia amusement park is the setting for a one-day laboratory exercise and evaluation of high school students' understanding of physics. The concepts and general techniques measured and the park's resources are discussed. Sample student responses are included. (JN)

Examines whether kindergarteners, second-graders, fourth-graders, and adults can extract relative weight information from observing collisions and lifting events, and if they can judge whether or not collisions are momentum-conserving. Subjects saw either videotapes of events or sequences of static images; younger children appeared to be…

Investigated what abilities and objectives can be measured on practical tests. Results suggest that these tests be composed of separate parts which measure the ability to perform an experiment and the ability to interpret and analyze an experiment. A brief description of the Dutch school system is included. (JN)
