Examined the effect of discovery and non-discovery classroom climates on college students learning of science process skills and biology content achievement. Results indicate students in discovery climate learned as much content as students in more direct class. These and other results are compared to those of an earlier study. (JN)

In this project, a resynthesis of the research dealing with student performance in new science curricula was conducted using refined statistical procedures. Results generally supported earlier meta-analysis studies. (CW)

Compared were the integrated process skills of American youngsters who studied for several years in an activity-based, materials-oriented program to a group of Japanese pupils who studied in a similar program and to an American group whose program was textbook oriented. Implications are discussed. (Author/CW)

The purpose of this study was to examine the effects of three instructional methods and conceptual systems orientation on achievement in a freshman general chemistry laboratory course. Traditional approach, learning cycle, and computer simulations are discussed. (KR)

Compared is an inquiry-oriented Biological Sciences Curriculum Study (BSCS) style laboratory approach with a more directive traditional approach on student outcomes in the cognitive and affective domains of learning. Differences in science achievement, reasoning ability, attitude, and stages of development are discussed. (KR)

Reports on a study that examined the differential effectiveness of traditional and discovery methods of chemistry instruction in Zambia. Compared were the teaching of science concepts, understandings about science, and scientific attitudes to learners at the concrete and formal levels of cognitive development. (TW)

Compares models of the classroom dynamics for a traditional laboratory setting and a problem-solving-centered environment, both at the eighth grade science level. Descriptive data indicate no differences in the models, whereas path analyses suggest that, in the problem-solving model, student behaviors significantly correlate to lesson structure,…
