Presents four Physics General Certificate of Secondary Education assessment practicals which can be photocopied for use in instruction. Includes notes for guidance of teachers in determining student skills in management and organization, designing and carrying out experiments to solve problems, draw conclusions, and select suitable apparatus for…

Describes teaching strategies that help students improve problem solving skills. Lists three factors good problem solvers were found to possess. Gives step by step instructions for solving problems. (MVL)

Describes two oscillating reactions: the Briggs-Raucher reaction using H202, KIO3, malonic acid, and MnSO4 which changes from yellow to blue, and the Belousov-Zhabotinskii reaction uses NaBrO3, NaBr, malonic acid, and ferroin solution and changes from red to blue. Includes a third color demonstration on the six oxidation states of manganese. (MVL)

Illustrates an interesting biomedical application of adsorption from solution and demonstrates some of the factors that influence the in vivo adsorption of drug molecules onto activated charcoal. Uses acetaminophen and N-acetylcysteine for the determination. Suggests several related experiments. (MVL)

Describes several experiments using the techniques of thermal analysis and thermometric titrimetry. Defines thermal analysis and several recent branches of the technique. Notes most of the experiments use simple equipment and standard laboratory techniques. (MVL)

Discusses a computer simulation to teach logic design using a Macintosh computer which allows circuits to be built piece by piece. Describes features of the simulation and presents several schematics drawn by the software. (MVL)

Discusses programs to provide a knowledge base and use the knowledge in a mode of artificial intelligence. Indicates that two methods of database storage are possible and opts to use a method using many data files while using a small RAM capacity. Lists several programs. (MVL)

Discussed are some uses of computers in chemistry classrooms. Described are: (1) interactive chromatographic analysis software; (2) computer interface for a digital frequency-period-counter-ratio meter and analog interface based on a voltage-to-frequency converter; and (3) use of spectrometer/microcomputer arrangement for teaching atomic theory.…

Reviewed is a television-based course available on videotape, "The World of Chemistry," which includes 26 programs. Discussed are the content, the sponsorship of the program, format, availability, and reviewer comments. (CW)

The theory behind concept mapping and advance organizers is reviewed. Special variations of concept mapping are presented. Evaluation using concept maps and long-term retention are discussed. (CW)

Discussed are some of the ways that community colleges may assist school districts and individuals with inservice teacher education. A program at Valencia Community College (FL) is described. Cooperation between the public school and the college is stressed. (CW)

A review of some of the different forms that biological ethics have taken in the past and of issues which are arising suggests that ethics should be taught as a part of biological education within a framework of history, futures study, training in clear thinking, and the development of empathy. (Author/CW)

Instructions are given for constructing two models, one to illustrate the general principles of symmetry in T=1, T=3, and T=4 viruses, and the other to illustrate the disposition of protein subunits in the T=3 plant viruses and the picornaviruses. (Author/CW)

Described are the use of two different tests designed to test for selected inquiry skills. Procedures, tests used, and results in several different countries are presented. Implications for classroom instruction are discussed. (CW)
