This article reports a systematic review of research on science programs in grades 6-12. Twenty-one studies met inclusion criteria including use of randomized or quasi-experimental assignment to conditions, measures that assess content emphasized equally in experimental and control groups, and a duration of at least 12 weeks. Programs fell into…

The merits of three approaches (explicit, reflective and implicit) to Nature of Science (NOS) teaching and learning in the context of a summer research experience on high school student participants' NOS ideas were explored in this study. The effectiveness of explicit over implicit approaches has been demonstrated in school contexts, but less…

This study presents a description and analysis of a ninth-grade integrated science curriculum developed and implemented by teachers within a high school science department and subsequently sustained for over 25 years. The Integrated Science Program (ISP) at Lakeside Southwest High School depicted here offers a unique example of longitudinal…

Describes and examines the effects of the eight-week Summer Science Training Program at the University of Iowa. There was no significant differences between students who had completed high school physics and those who had not on the final course examination, course grade, and attitudes toward physics. (Author/YP)

Investigated were factors affecting student choice of academic orientations in science in secondary schools of Israel. Selection of a physical science stream of course work was found to be related to socioeconomic background. (SL)

Examined trends in teachers' recommendations for changing elementary and junior high school science programs between 1978 and 1982. Results discussed are based on responses of British Columbia teachers- 3,040 teachers in 1978 and 1,631 in 1982, with return rates ranging from 77.5 percent to 85 percent. (JN)

Examines the educational value of exhibits for transferring wildlife information to high school students. Reports that the passive exhibitry technique produced increases in the wildlife knowledge of students. (Author/YP)

Determines how the use of a science education program affected selected ninth-grade students' comprehension of science reading material. The different effects of the program depended on students' reading and mathematics scores. (Author/YP)

Describes the Intermediate Science Curriculum Study (ISCS) instructional system and its underlying rationale, and outlines the planning and developmental procedures used to construct this individualized junior high school science program. (JR)

Reports on a study that examined the performance and science attitudes of two groups of students in a college chemistry course. One group had enrolled in high school chemistry; the other group had not. There was no difference between groups as to attitude toward chemistry or academic performance. (RT)

This study was concerned with the relationship of student achievement and teacher participation in National Science Foundation institute. Results indicated a positive effect from institute attendance; however, the significance of the effect varied by subject and grade level, and was influenced by factors outside the realm of this study. (SL)

Examines effects of NSF institute participation by secondary teachers. Tests alternative hypotheses that (1) an increase in student achievement associated with teacher inservice work may be accompanied by more positive attitudes towards science; or (2) that teachers may increase their students' achievement at the expense of less positive science…

Describes a Teacher Intervention Program modifying classroom techniques and environments for fostering the participation of girls in high-school science classes. Reports that students who were taught by trained teachers, compared to students who were not, have higher scores on tests of attitudes toward science, perceptions of science, and science…

Findings reveal that students who are skillful in perceptual restructuring attain significantly higher mean achievement scores in science, in knowledge of science, and in the ability to apply what has been learned in unfamiliar contexts than students with low structuring ability. (Author/MA)

Examined is the effectiveness of a smoking-prevention program in modifying high school students' attitudes and values in such categories as health, peer pressure, and social image as related to smoking. The intervention lasted four to six weeks within the framework of ninth- and tenth-grade biology classes. (Author/YP)
