Described is a base-friction modeling technique for studying the development of collapse structures in jointed rocks. A moving belt beneath weak material is designed to simulate gravity. A description is given of the model frame construction. (Author/SA)

Discusses various aspects of in-service training and the design of self-instruction material. Special reference is given to materials for application in various places but developed at a central location. Results are given of the use of experimental materials in medical laboratories in The Gambia. (Author/SA)

Examines why centers for the support of science and mathematics teaching are needed, how they might function, and how they might be established. Such centers would provide for the professional development of teachers and could give teachers a voice in the development of new science and mathematics instructional materials. (Author/IRT)

Presented in this article is a set of guidelines to follow in the selection of a science textbook. Instructions on how to examine textbooks are given. Topics considered are types of experiments, appropriateness of content, definition of concepts, meaningful activities, sequence, reading level, eye appeal, and safety. (SA)

A puppet show depicting a gathering of the planets in the earth's solar system is described. Dialogue as well as a description of the method of constructing the planet puppets is included. (SA)

Suggestions are given for dealing with "senioritis" in high school students. These include offering college-level courses at a reduced cost. A description of introducing the college freshman biology course at Syracuse University into a high school program is given, with guidelines to promote success. (Author/SA)

An experiment for senior college undergraduate physics students is described. Amorphous tungsten trioxide films are suggested for use since they have a unique electrochromic system. (Author/SA)

Describes a high school chemistry experiment which involves the reaction between calcite and hydrochloric and sulfuric acids. This reaction can be carried out as a projected demonstration and on an individual basis. (HM)

Dispels several myths about handicapped students and their participation in science learning laboratories. (SA)

The approach described in this article represents a combination of teaching techniques that were successful for a high school biology teacher. The process is described as shared decision making and the student becomes an active partner in the learning process. (Author/SA)

Described is a graduate course in the process control curriculum at the University of Wisconsin that integrates real-time computing into process control teaching. Lecture topics and recent graduate laboratory projects are presented. (BT)

Described is a graduate and senior level course utilizing the case study approach in chemical engineering at the University of Delaware that stresses the function and economics of the chemical processing industry. A history of the course development, course outline, and teaching methods used are included. (BT)

A course is described that is designed to encourage exploration, conceptual invention, and expansion of an idea. Results are given that relate to curricular experimentation with chemistry. (SA)

This inexpensive but informative experiment for undergraduate biochemistry students involves isolating phosphatidyl choline from spinach leaves. Emphasis is on introducing students to techniques of lipid extraction, separation of lipids, identification using thin layer chromatography, and identification of fatty acids. Three periods of three hours…

Demonstrates how to use the concept of phlogiston to teach oxidation and reduction reactions. Discusses the project as an exemplar for integrating the history, philosophy, and sociology of science to teach basic scientific concepts. Contains 70 references. (DDR)
