Misconceptions are systematic, intelligently conceived, and quite reasonable theories that have been constructed on the basis of experience. Research studies on misconceptions have indicated that students develop intelligently conceived and sophisticated concepts of science. Although some of these are compatible with the principles of modern…

This study examines how academic assertiveness in junior high school students affects conceptual change and the degree to which their assertiveness affects the conceptual change of partners paired with them for a series of activities using a computer simulation of the human cardiovascular system. The sample was a group of 90 eighth-grade students…

Results of surveys and studies suggest that too few African-American and female students aspire to and achieve doctoral degrees in biological sciences. It has also been suggested that gender and racial inequities exist in teaching and research faculties in higher education, especially in the biomedical sciences. Thus, few role models are available…

The use of computers to facilitate learning is yet to make an appreciable in-road into the teaching-learning process in most developing Third World countries. The purchase cost and maintenance expenses of the equipment are the major inhibiting factors related to adoption of this high technology in these countries. This study investigated: (1) the…

The departments of mathematics, biology, and chemistry and the teacher education program at the College of Saint Elizabeth (New Jersey) are working in partnership with a public school to improve the teaching of mathematics and science in preschool through high school levels and to recruit minority science and mathematics teachers. The program aims…

This paper presents Rowland's Ways of Knowing and Decision-making Model for curriculum development and how it can be applied to environmental education curricula. The model uses a problem solving approach based on steps of: (1) coming to know the problem through the ways of knowing of the disciplines and personal knowledge; (2) proposing solutions…

Generative learning strategies are the focus of the study described in this paper. Research questions pertain to the effect of practice in the generation of analogies and summaries by Grade 7 students on their achievement in science, the different types and numbers of analogies that students generate, and students' perceptions of the effectiveness…

This paper reports on the progress through February 1975 of the Human Sciences Implementation Project of the Biological Sciences Curriculum Study (BSCS). The project's objectives are to disseminate information about the BSCS Human Science Program (HSP) curriculum and to train the staffs of regional centers in the philosophy, rationale, and…

A model incorporating both academic and nonacademic factors as determinants of productivity was tested with samples of physical and biological scientists, social scientists, and humanists taken from the 1972-73 American Council on Education survey of faculty at U.S. institutions of higher learning. Considerable variation was found in the process…

This study is an extension of an on-going longitudinal study, the Girls Engagement With/In Science (GEIS) Project. The GEIS Project was designed to understand how girls who are poor, minority or both, engage in science. The two teachers who form the focus for this study are these girls' 7th and 8th grade teachers. Data for this interpretive…

As part of an ongoing study of the content knowledge, instructional beliefs, and instructional practices of middle school, high school, and college science teachers, the hypothesis that there are systematic differences across academic levels in these teachers' conceptual understanding of the same content-specific subjects was studied. Eight middle…

This study is part of a larger study of teachers' use of curriculum materials in planning and teaching fifth-grade science. The study focused on one of nine teachers observed teaching "Communities," an activity-based unit from the SCIIS science program (a revision of the original Science Curriculum Improvement Study).…

Six of the nine papers in this collection focus on biological and medical science libraries; the remaining three are concerned with social science libraries. The papers on biological and medical science libraries appear first in this list: (1) "Standards for Medical and Health Care Libraries: Canada" (Jan Greenwood, Canada); (2) "Standards for…

Reported are results of a study designed to determine developmental patterns in proportional reasoning and to determine if these patterns are similar regardless of educational level and regardless of problem context. Data from 2282 subjects in grades 6-13 were collected using the Test of Logical Thinking (TOLT), and then examined for subjects who…

A series of statistical analyses was conducted of institutional and departmental trends in women's graduate enrollment and employment in science and engineering in the 50 leading doctorate-granting institutions. Site visits to a diverse group of nine selected institutions were conducted. The schools were selected to be representative of the total…
