Reviewed is some of the experimental evidence for apostatic selection from work with artificial prey. Guidelines for further experiments are suggested including experimental design, analysis, variables, and selection in the wild. (Author/CW)

Provides a set of guidelines for infection control of the Acquired Immune Deficiency Syndrome and the serum hepatitis viruses during blood typing procedures. Emphasizes that disposal of blood contaminated materials should comply with local health department recommendations. (RT)

Presents a method which introduces biology students to some fundamental aspects of scientific methodology. Explains simple muscle testing procedures, a historical perspective, experimental variables, pedagogical uses, and possible mechanisms of the muscle response phenomenon action. (RT)

Explains the surge in publishing activity of science, the development of a standardized technical vocabulary, and the adoption of modern equipment for the transmission of information. Discusses the pioneer in scientific journalism, scientific writing, and the progress of Arab scientific journalism. (RT)

Discussed is single crystal X-ray crystal structure analysis. A common link between the NMR imaging and the traditional X-ray crystal structure analysis is reported. Claims that comparisons aid in the understanding of both techniques. (MVL)

Presents survey results from freshman engineering students at Colorado State University. Identifies the highest levels of math and computer courses taken. Notes although most students took high school calculus, 48 percent failed the college's analytical trigonometry examination. Develops practical ideas for the future. (MVL)

Images as a multi-faceted topic were used to teach an introductory course in Technological Studies. Widely differing thought patterns between the liberal arts and technologists were observed and are described. The syllabus is found in an appendix. (Author/YP)

Provides listings of the top 25 universities producing chemistry graduates for the year 1987-88 in the areas of: total bachelors; certified bachelors; masters; and doctoral. (MVL)

A National Policy for environmental education in South Africa was proposed in 1989. This paper examines the impact of Apartheid ideology and structure upon in-service environmental education teacher training in South Africa and identifies and explores the viability of alternative channels for such training. (Author/CW)

Describes a computer program presenting four genetics problems to monitor the problem solving process of college students. Identifies three main areas of difficulty: computational skills; determination of gametes; and application of previous learning to new situations. (Author/YP)

Evaluates 10 courseware packages covering topics for introductory physics. Discusses the price; sub-topics; program type; interaction; possible hardware; time; calculus required; graphics; and comments on each program. Recommends two packages in projectile and circular motion, and three packages in statics and rotational dynamics. (YP)

Evaluates the overall economic efficiency of a closed resource cycle. Uses elementary thermodynamic definitions of overall thermal efficiency for determining an economically quantifiable basis. Selects aluminum for investigation and includes a value-entropy diagram for a closed aluminum cycle. (MVL)

Describes an advanced NMR project that can be done with a 60-MHz continuous-wave proton spectrometer. Points out the main purposes are to give students experience in second-order NMR analysis, the simplification of spectra by raising the frequency, and the effect of non-hydrogen nuclei on proton resonances. (MVL)

Introduces a research activity program in which 10 students worked during the summer as part of a team that developed software for a larger project. Lists names of students, the professors with whom they worked, and their research efforts. (RT)

Considers research concentrating on the correlation between knowledge structure and learning. Suggests implications of this research to classroom teaching. Cites characteristics of unsuccessful and successful problem solvers. (RT)
