Describes the objectives and contents of a physical science course for preservice teachers in a teacher's college in England. The course extends over three years, emphasizes physical science concepts, and is laboratory oriented. Discusses how the topics of spectroscopy and crystallography are treated in the course. The syllabus is included. (LC)

Offers the potential user of digital computers information and suggestions for acquiring a time-sharing system. The results of a survey of the equipment, cost, and services offered by a sample of time-sharing firms are presented. (LC)

Describes a two-year college science program designed to study not only the scientific conepts, but the humanistic aspects of the interaction of science and society. The courses are historically developed utilizing the physical sciences the first year, and the life sciences the second year. (RR)

Reviews three audiovisual instructional aids, providing information on time, format, catalog number, price, and supplier. "Distillation: Simple and Fractional,""The Periodic Table," and "Manmade Macromolecules" are considered to be excellent materials for secondary school chemistry classes. (JN)

Provided are 10 papers presented during a symposium on teaching cardiovascular physiology outside the lecture hall. Topics addressed include a mechanical model of the cardiovascular system for effective teaching, separate course for experiments in cardiovascular physiology, selective laboratory (alternative to cookbook experiments), cardiovascular…

The shore crab (Carcinus maenas) is an excellent subject for school study, both in the field and the laboratory. It is easily collected and maintained and can be used for a wide range of investigations. Some background details are given and possible areas of investigation suggested. (Author)

Describes common artificially produced organized media such as colloids, surfactants, and polymers and their usefulness in studying complex biochemical processes. Discusses selected recent photophysical and photochemical exploitations of these systems, including artificial photosynthesis, in situ generation of colloidal gold and platinum,…

Describes equipment and procedures for an experiment using diodes to introduce non-linear electronic devices in a freshman physics laboratory. The experiment involves calculation and plotting of the characteristic-curve and load-line to predict the operating point and compare prediction to experimentally determined values. Background information…

Describes a safety program adopted by Southeastern Louisiana University. Students are given detailed instructions on laboratory safety during the first laboratory period and a test which must be completely correct before they are allowed to return to the laboratory. Test questions, list of safety rules, and a laboratory accident report form are…

Discusses research indicating that presenting students with large amounts of information while their concepts are primitive prevents them from grouping/handling the very information they need to make concepts develop. Reducing the load or providing strategies to help students group/sequence the load are recommended. (JN)
