Describes nature and logistics of a learning cycle approach to teaching exponential growth and the energy crisis. Used with both science and nonscience majors, the cycle uses no algebra, never mentions the terms exponential or logarithmic, and requires a calculator. Instructions for obtaining student and instructor materials are provided.…

Describes apparatus and method used to allow rapid and repeated measurement of acceleration of a ball rolling down an inclined plane. Acceleration measurements can be performed in an hour with the apparatus interfaced to a Commodore PET microcomputer. A copy of the BASIC program is available from the authors. (Author/JN)

Describes a demonstration to initiate discussion about electrostatic effects. Also describes and evaluates a Magnetic Bubble Apparatus, a device which exhibits several phenomena related to magnetic domain formation. Includes manufacturer's response to the evaluation. (JN)

Results of a questionnaire survey of 455 two- and four-year institutions on the status on noncalculus physics courses are presented. Responses from 265 questionnaires focus on enrollment, textbooks, reasons for textbook changes, laboratory manuals, and nationally standardized set of laboratory experiments. Selected comments from individual…

Reviews software produced by Cross Educational Software to teach college-advanced high school students how to determine forces/torques acting on rigid bodies in static equilibrium. Designed for use with Apple II/II+ (Applesoft), 10 minutes to one hour are required for the five low to moderate interactive tutorial programs. (Author/JN)

Describes four body-lever models (biceps, triceps, back lever when lifting, foot lever and Achilles tendon muscle) used in noncalculus physics courses. Instructions for constructing the wooden models are provided. Also describes an improvement on a centripetal-force apparatus so that it is easier to operate. (JN)

Describes a computer program designed to simulate the regulation of acid-base balance, emphasizing regulatory compensations involved in the total process. Includes discussion of equations involved, a sample run of the program, and program listing (MicroSoft Basic). (JN)

Describes a multidisciplinary project/experiment in which undergraduate students repaired a nonfunctional Helium-Neon laser. Includes experimental procedures used and results. (JN)

Describes a simple model to illustrate several aspects of the biochemical origin of life and the process of evolution through natural selection. The model has students predict the outcome of evolution in populations of beads. Instructional strategies using the model are also discussed. (Author/JN)

Argues that science dominates our culture and has developed an institutional similarity to the religion which dominated earlier eras. Uses religion as a metaphor in advocating a scientific reformation in science instruction so it may be accessible to all and not the property of a few. (Author/JN)

A research astronomer outlines a typical day's work, describes the conventional route to become a research scientist, and discusses the kind of research done and some areas of expertise needed to accomplish the research (reading skills, computing, photography, electronics, cyrogenics, literary skills, verbal skills, and detective skills) among…

Describes a program for high school students who are between their junior and senior years which provides an opportunity to take part in aviation courses at the University of North Dakota. Students take courses leading to a private pilot license, and earn college credit for their efforts. (JN)

Discusses the role and use of microcomputers in scientific research, from monitoring instruments to controlling experimental processes. Included are descriptions of a computer-controlled protein sequencer and gene synthesizer, and microcomputer uses in medicine, physiology, biochemistry, and geology. (JN)

Describes a topics course offered at the University of New Mexico entitled "Lasers in Chemistry," which is designed for beginning graduate students and advanced undergraduates in all areas of chemistry. (CS)

Discusses recent administrative proposals to curtail expenditures in universities, including funding for student aid and for scientific instruments and facilities. Argues that governmental support of young scientists is needed, as the success of American science has depended heavily on European talent arising from the consequences of World War II.…
