Argues that "appropriate practical work" in mathematics aids understanding. Presents ideas and activities for teaching mechanics. Discusses modelling, problem formulation, and interpretation. (PK)

Presented is a description of a BASIC program to be used on an IBM microcomputer for calculating and plotting synthetic seismic-reflection traces for multilayered earth models. Discusses finding raypaths for given source-receiver offsets using the "shooting method" and calculating the corresponding travel times. (Author/CW)

Addresses the call for university undergraduate physics programs in Great Britain to be more concerned with the relationship between physics and the outside world, particularly with business and industry. Describes some of the constraints on this movement, as well as some of the strategies currently being used to overcome the obstacles. (TW)

Presents data which leads to the construction of a response to the question of how different phases of the learning cycle influence physics students' content achievement and attitudes. Discusses the importance of the learning cycle in science instruction and the strength of using contrasting techniques (qualitative and quantitative) in research.…

Reviews a National Science Foundation funded workshop ("Investigations in the Natural Sciences") for science teachers on how to use laboratory centered materials developed by the Science Education Center at the University of Oklahoma. Presents the results of a survey of the participants. Highlights the program's strengths. (CW)

Discusses the use of remote sensing from satellites to monitor glaciers. Discusses efforts to use remote sensing satellites of the Landsat series for examining the global distribution, mass, balance, movements, and dynamics of the world's glaciers. Includes several Landsat images of various glaciers. (TW)

Describes an activity in which young children explore the concepts of light by predicting the shape of shadows. Different configurations of light sources are used and objects are held in different positions. Sample questions to be asked of the children before, during, and after the activities are included. (TW)

Provides an overview of the approach, objectives, and unit offerings of the Science and Technology in Society (SATIS) project. Lists physics-related SATIS publications and describes selected programs. Suggests how SATIS units can be used as a supplement to existing materials. (ML)

Discusses the concerns and problems associated with the secondary school-higher education interface in West Germany. Reviews reform efforts and attempts at problem resolution with specific emphasis on physics instruction. (ML)

Presents two methods used to measure the refractive indices and double-refraction of fibers. Experiments are described, with one involving the use of Pluta microscope in the double-beam interference technique, the other employing the multiple-beam technique. Immersion liquids are discussed that can be used in the experiments. (TW)

Promotes the use of computer modelling in physics instruction. Describes Dynamic Modelling System (DMS) and the procedures employed in applying it to problem solving in physics. Provides fundamental information on BASIC language and techniques for using DMS. (ML)

Describes the development and implementation of curriculum materials that discuss nuclear weapons and the evaluation of those materials by administrators, teachers, and students. Also discusses the place of the study of nuclear weapons in the curriculum and aims of the materials. Suggested student activities are included. (JM)

Describes several methods of executing lecture demonstrations involving the recombination of the spectrum. Groups the techniques into two general classes: bringing selected portions of the spectrum together using lenses or mirrors and blurring the colors by rapid movement or foreshortening. (JM)

Describes computer measurement of capacitor charge decay, change of fringe width with color, computer simulation of color mixing, Doppler effect/carrier waves, gravitational waves, microwave apparatus, computer simulation of Brownian motion, search coils and problems with the teaching of the relationships of velocity, frequency, and wavelength in…

Discusses several aspects of physics education in China. These include the school system, physics curriculum, physics textbooks and reference books used, preservice training for teachers of senior and middle schools, and in-service programs and activities for qualified physics teachers. (JN)
