Presents examples of physics activities using common objects such as a tuning fork, umbrella (for double diffraction patterns), and a toy car. Provides questions designed to stimulate student curiosity/interest and which provide models for developing additional units on everyday objects and toys. (JM)

Offers a rationale and method for using the hand controllers (game paddles) in the design of computer programs for student use. Methods for their use in entering data as well as in conducting pendulum and acceleration experiments are provided. Complete program listings (for Apple) are included. (JN)

Demonstrations, procedures, games, teaching suggestions and information on a variety of physics topics are presented, including hydraulic rams, units and formulae, static electric motors, a computer graphics program, diffraction, adaptation of a basic meter, photoelasticity, photo-diodes, radioactive decay, and analog-digital conversions. (DC)

Describes industrially important yeasts, molds, bacteria, and actinomycetes. Discussed in detail are microbial products, such as primary metabolites, secondary metabolites, enzymes, and capsular polysaccharides. Traces the historical background of human cell culture, mentioning recombinant DNA research and hybridization of normal mammalian cells…

National Association for Research in Science Teaching (NARST) members (N=101) responded to a 1979 survey, listing 398 statements of needed research. Three categories of needed research emerged as the greatest concern of these NARST members: instructional strategy, learning, and student/teacher attitudes. (Author/JN)

Outlines a variety of laboratory procedures, demonstrations, and classroom materials including a technique for estimating speed of electromagnetic waves; a support for multipin components when soldering; use of dynometer to measure force; bending light; using a microcomputer to measure and produce voltage; force-distance curves; and two games. (DS)

Describes an interdisciplinary minicourse on dinosaur fossils, morphology, ethology, and energetics. Suggests and provides examples of hands-on activities for junior high school- through college-level students. (DS)

Describes equipment, activities, and experiments useful in chemistry instruction, including among others, a rapid method to determine available chlorine in bleach, simple flame testing apparatus, and a simple apparatus demonstrating the technique of flash photolysis. (SK)

Describes equipment, activities, and experiments useful in physics instruction, including among others, a list of articles relating to physics topics, computer interface that makes a computer cost effective, use of a guitar in vibrating string experiments, and photoelectric aids to the measurement of distance, speed, velocity, and acceleration.…

Describes the current situation in Canada regarding the consequences of an expected decline in university enrollments, when it was originally expected that the university system would solve problems of society needing science-based solutions. Parallels are drawn with the situation in the United States. (CS)

Despite rising enrollments, college biology education has until recently lagged behind other science disciplines in reforming undergraduate instruction. However, new approaches are emerging, including introductory classes that focus more on concepts, laboratory assignments that are increasingly sophisticated, and more in-depth curricula for…

Described is a measure of the self-efficacy of preservice elementary science teachers. Field experiences, peer teaching, and the self-evaluation of microteaching are introduced as ways to enhance science teaching self-efficacy. Validity and reliability data are presented. (KR)

Described is an activity that incorporates a computer, geometry, algebra, trigonometry, and calculus to answer questions about the planet Mars. A possible crescent of Mars is compared to those of Venus and Mercury. (KR)

Described is a course focused on how women are globally connected through experiences with technology. Specific topics include computers, world hunger, reproductive strategies, and solid waste disposal. Discussed is the impact of the class on students and the faculty. (KR)

Discusses how computers can be applied in the science laboratory. Describes the hardware and software associated with the laboratory interface system. Outlines a three-and-a-half-day workshop to train secondary science teachers to apply computer interfacing in their laboratories. Lists 5 references. (YP)
