Presents a brief description of the Dutch school system's structure. Describes the most important issues that have contributed to the development of physics education resulting from changes with respect to the physics curriculum, the final physics examination, and stimulation by a Dutch curriculum development project. (RT)

Discusses a method to use several diffraction gratings at one time with one hydrogen bulb. Describes the experimental set up, background, and results. (CW)

Explains gyroscopic motions to college freshman or high school seniors who have learned about centripetal acceleration and the transformations of a couple. Contains several figures showing the direction of forces and motion. (YP)

Presented are two case reports about an instructional experiment. "Peer Perspectives" uses nonspecialized faculty to experience some aspects of an introductory course for providing perspective, insight, and feedback to those who wish to make their courses more appropriate to nonmajors. (YP)

Presented are two case studies on the perspective of the history of science. Provided are the contributions of 12 famous scientists with their historical illustrations and diagrams. Five conclusions are drawn from these studies. (YP)

Reports the results of a radioactivity survey in England. Discusses the aim of the survey, experimental procedures, analysis, and results. Shows several diagrams, graphs, and tables. (YP)

Demonstrates several objects rolling down a slope to explain the energy transition among potential energy, translational kinetic energy, and rotational kinetic energy. Contains a problem from Galileo's rolling ball experiment. (YP)

Introduced are 20 places for field trips throughout the United States. Included are the location, explanation, famous things, and references for each place. (YP)

Explains miniprojects in high school science courses. Shows the project idea table and five examples with explanations. Discusses the experience and some positive results for students. (YP)

Described are the objectives, schedule and evaluation of an institute. Listed are demonstrations performed illustrating physical properties and physical change, energy changes, and chemical equilibrium. Discussed are the advantages of using demonstrations in teaching precollege chemistry. (CW)

Presents an adaptation of "Euler's Circles" as a metacognitive tool for learning. Provides background about diagraming and learning theory. Details concept circle diagrams and considers their relationship to Ausubelian learning theory. Gives examples of the use of concept circles and rules for concept circle construction. (CW)

Suggests some of the basics and reasons for teaching balance. Explains how the concept of a cantilever can be used. Describes 25 activities for observing, testing and learning about balance. (CW)

Investigates the influence of differing elementary science experiences on the interests of girls and boys in secondary school science. Attempts to link these experiences with science performance. Focuses on the elementary experience of girls and compares the sexes. (CW)

Describes a unique educational program at the Peers School (Oxford, England) involving integration of science and craft and design technology and how it is structured. Shares practical experiences and difficulties. Comments on questions that have been posed regarding this program. (CW)

Attempts to show that not only can density be taught to lower ability pupils but that by doing so, there is the possibility of assisting pupils to develop their reasoning powers. Lists teaching activities that help in this process. (CW)
