Describes the relationship of Popper's theory of knowledge to chemistry instruction. Suggests that students be allowed to learn from their mistakes and presents five experiments with an implicit falsification purpose. (JN)

Reports results of a study aiming to determine the initial levels of understanding of bioethical terms and concepts of college students. Data are summarized from the development and field testing of the Cognitive Biological Concept Assessment Instrument, which was administered to high school and college students and secondary science teachers. (CS)

Describes an inexpensive physics apparatus and experiment to dynamically determine Young's modulus for thin reeds and wire samples. (HM)

Describes advances in catalytic determinations and other applications of kinetics in chemical analysis. A section on instrumentation and computers is included. Cites 158 references. (CS)

Presents tabular information concerning recent research in the field of enzymes in analytic chemistry, with methods, substrate or reaction catalyzed, assay, comments and references listed. The table refers to 128 references. Also listed are 13 general citations. (CS)

Describes aspects of the preprofessional program for minority students in the health sciences at the University of Washington, including a summary of the history of the entire preprofessional program, factors bearing on selection and placement of students, and motivational factors. (CS)

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)
