Twenty-eight secondary science student teachers were included in a self-evaluation study. The instrument consisted of 89 statements describing observable teaching behavior. PGR was found to be useful in teacher evaluation when used with video tape observations. (LS)

This report lends confirmation to the feasibility of employing punishment in modifying or eliminating socially unacceptable behavior, and is another example in which amelioration of symptomology seemed to precede a thorough investigation of etiological factors. (Author)

The syllabus for a refresher course on the physiology and biochemistry of receptors (presented at the 1983 American Physiological Society meeting) is provided. Topics considered include receptor regulation, structural/functional aspects of receptors for insulin and insulin-like growth factors, calcium channel inhibitors, and role of lipoprotein…

The effects of passive exercise of the extremities on peripheral vision of muscular dystrophic children aged 9 to 13 years was investigated. Compared to control subjects, those who experienced six minutes of passive exercise evidenced increased peripheral vision. Curriculum revisions for muscular dystrophic children indicate the importance of…

Distance running tests evaluate a unique physical activity that is an important component of many other physical tasks. Factor analytic studies have clearly shown that distance running tests assess underlying abilities and physiological capacities that are different from those assessed by runs of shorter duration.

Widespread claims of extraordinary longevity continue to receive widespread publicity even in first-rate publications. The story of Charlie Smith is reasonably typical of such cultural apocrypha. Development of chemical methods of determining biologic longevity promises to end what often has been heralded as evidence of national distinction.…

Information from scientific journals on the biology of skin color is discussed. Major areas addressed include: (1) biology of melanin, melanocytes, and melanosomes; (2) melanosome and human diversity; (3) genetics of skin color; and (4) skin color, geography, and natural selection. (JN)

In a five-year study, second-year human physiology students were grouped for laboratory according to previous physiology and laboratory experience. No significant differences in course or board examination performance were found, though correlations were found between predental grade-point averages and grouping. (MSE)
