Four types of proportionality problems were administered to: (1) secondary school students who were enrolled in Project Physics, and (2) students not enrolled in physics. Both samples were randomly selected. Groups were not found to differ significantly in problem solving ability but both revealed that the ability to solve certain problems was…

Debates as to the appropriateness of using the Karplus Islands Puzzle as an instrument to assess formal-operational thought. (CP)

Discusses difficulties in the high school preparation of college-bound physics students existing within the school systems of Great Britain. (SL)

Discusses a study which compared differences in ratio construction made by high school freshman and junior students. Reports that more freshmen than juniors selected solutions involving one variable, whereas juniors chose solutions that coordinated two variables in a mathematical or verbal rule. Reviews implications in problem solving and concept…

This study was developed to provide advice to teachers on how to use rules in teaching experimental design in science classes. A review is presented on the use of rule in science teaching and the effects of instructional treatments are assessed on Canadian high school students' skills of experimental design. (ML)

Reports on a study which examined the relationship of classroom environment to attitudes toward science and achievement in science among tenth grade biology students. Results indicated that student attitude toward the classroom environment was a signficicant predictor of the student attitude toward science. (TW)

A comparative study of textbook terms was conducted to determine what high school science skills are necessary for success in associate degree physical science courses. Results indicate that, although enrollment in technology-training programs is increasing, high school textbook treatment of terms remains inadequate preparation for junior college…

Discusses the use of astrological signs as a vehicle for getting students interested in astronomy. Describes the construction and use of simple stellaphane starframes that can be used to locate astrological constellations. Provides instructions for photographing constellations with a 35 millimeter camera. (TW)

Discusses the parameters of values clarification and of science and reviews the differences between them. Contends that values clarification is nonscience and that students should be helped to appreciate the ways nonscience is similar and dissimilar to science and the place of both in the conclusion-reaching process. (ML)
