Five types of models are discussed as they relate to their function in the sciences and science teaching. These include scale, analogue, mathematical, theoretical, and archetypal models. (SA)

Describes the role of women in Burmese society and the quality of women within the scientific community. Data are given on the numbers of students in Burmese professional schools and the distribution of sexes among the teaching staff of the science departments of the Arts and Sciences University in Rangoon. (Author/SA)

Described are different chemistry curricula that use lecture-experiments. Different components are discussed within the lecture-experiment format, such as determinism, memory, note taking, descriptive chemistry, and holistic chemistry. Also discussed are different personalities in chemistry education. (DS)

Described is a Piagetian learning cycle based on Monte Carlo modeling of several simple reaction mechanisms. Included are descriptions of learning cycle phases (exploration, invention, and discovery) and four BASIC-PLUS computer programs to be used in the explanation of chemical reacting systems. (Author/DS)

Described is a diffusion apparatus to be used in an undergraduate physical chemistry laboratory experiment to determine the diffusion coefficients of aqueous solutions of sucrose and potassium dichromate. Included is the principle of the method, apparatus design and description, and experimental procedure. (Author/DS)

Uses the irruption theory in explaining the occurrence of the Darwin finches in the Galapagos Islands as an example of how alternative theories can be presented in an educational setting. Advocates the comparison of alternative theories to encourage creative thinking and a critical attitude. (CS)

Provides a coding system, with flow charts, for "Hazchem," which provides an application of the knowledge of chemical behavior to emergency situations. (CS)

Presents the steps for drawing a block-diagram from a map in the area of structural geology. The author recommends first platting on the orthographic net, all directional data with respect to geographical reference axes. (Author/SA)

Describes a competency-based, modular laboratory course emphasizing the synthesis and characterization of polymers and directed toward senior undergraduate and/or first-year graduate students in science and engineering. One module, free-radical polymerization kinetics by dilatometry, is included as a sample. (CS)

Describes the organization of the aviation programs within the School of Technical Careers at Southern Illinois University at Carbondale. The associate degree programs in aviation include aviation and avionics technology and flight training. The baccalaureate programs include a variety of aviation specialization possibilities. (SA)

Outlines a variety of laboratory procedures, discussions, and demonstrations including in vitro contraction of muscle fibres and muscle proteins, sucrose density-gradient centrifugation, fern spore development, digestion of starch, construction of a small mammal trap, microscope selection, and occurrence and toxicity of mycotoxins. (GS)

Outlines a variety of laboratory procedures, discussions and demonstrations including the preparation and analysis of a square planar copper (11) complex, thermit reactions in a sand mould, product solubility, an aid for learning common oxyanions, thermal decomposition of nitric(v) acid. and nine others. (GS)

Outlines a variety of laboratory procedures, discussions, and demonstrations including a no-solder circuit board, damped to maintained oscillations with L-C circuits, polaroid strobe photos, resistive putty, soldering and circuit checking exercise, electromagnetic radiation, square pulses in C-R circuits, and testing an oscillating system. (GS)

Presents notes on the objectives of laboratory instruction, the design of assessment systems on the principles of criterion-referenced measurement, student ability to measure, and student attitudes toward the importance of physics. (GS)

Presents arguments for and against the viewpoint that the teaching of chemistry and of physics should fall in line with modern mathematics. Concludes that modern mathematics has been beneficial in some respects and harmful in others. (CS)
