This research tested the validity of the prevalent assumption that a teacher's conception of the nature of science influences his/her classroom behavior. The subjects consisted of 18 senior high school biology teachers and one randomly selected tenth-grade biology class of each teacher. Each class (mean size of 22.72 students) was heterogeneous…

The Amateur Radio Satellite Communications project had, as its goal, the assembly of an amateur radio satellite station in a high school physics classroom. Specific objectives were to provide: (1) a special source of interest as a motivator for attracting students and building public relations; (2) a center of interest as a motivator for the study…

This study: (1) comprehensively reviews previous research on the treatment of evolution in high school biology textbooks; (2) describes the treatment of evolutionary theory, including mention of creationist explanations of the development of life forms, in the most recent editions of 15 high school biology textbooks from the major publishers; and…

The problem of this study was to develop, validate, and establish the reliability of a computer simulation which would: (1) distinguish between concrete and formal thinking patterns related to control of variables; (2) be easily administered to a class of secondary school age subjects; (3) preserve the interactive aspects of the Piagetian task;…

Organizations such as the Ohio Academy of Science sponsor programs to encourage junior and senior high school students to conduct science projects. These programs are designed to give students who might pursue careers in technical areas a realistic foretaste of some of their future professional responsibilities, including the effective…

This study compared male and female enrollment and achievement in high school physics courses. The expectations were that enrollment of females would be higher than the 35 percent reported in a 1969 study and that the achievement of the sexes would be equal. The findings indicated that the percentages of females were very similar to those in the…

Describes a method for introducing and teaching to junior high school students the concepts involved in constructing a dichotomous key. (JR)

This PSI unit may be used as a self-study guide or as part of a PSI or regular astronomy course to provide a simplified procedure for the casting of natal horoscopes. (Author/DT)

Describes the activities of the Esso company to promote the improvement of science education in the schools. (PEB)

Continues the work done by Mackay (1971) and Gardner (1973) in which attitudes of students enrolled in PSSC physics were assessed. (PEB)

Describes a science activity, using safety pins, illustrating steps in problem solving. (PEB)

Describes an experiment, easily repeated in the classroom, designed to determine whether members of the species Drosophila melanogaster show selective preference in choice of mates. (PEB)
