Analyzed and classified were Individualized Science Instruction System (ISIS) minicourse performance objectives and criterion-referenced test items according to Bloom's cognitive "Taxonomy" to determine levels of cognition emphasized. The findings indicate that ISIS minicourse test objectives are written primarily at the knowledge and…

Reports on the analysis of science curricula carried out across Canada within the framework of the Second International Science Study by: (1) describing the background to the study and the research methodology employed; (2) showing how data were organized; and (3) discussing meanings derived from the data analysis. (JN)

Examined is the program and professional development process that has characterized past and current science curriculum reform efforts. Illustrated are fundamental educational reform problems. Discussed is the importance of teacher involvement in educational decision making. (KR)

Presents concept mapping as an effective tool for developing an integrated curriculum. Includes examples of concept maps that represent an entire veterinary curriculum, specific courses, and case-based exercises. (21 references) (Author/JRH)

Reviews research from the past 40 years on students' and teachers' conceptions of the nature of science, clarifies the basic assumptions and logic which have guided earlier research efforts, contrasts the results from qualitative and quantitative research, makes recommendations about research methods, and suggests avenues for future research about…

Examined are two aspects of science education--the nature of science and curriculum reform. Contemporary views on the tentative nature of science and a generative model of learning are synthesized. (KR)

Describes the development of a valid and reliable method to quantitatively analyze the content of science textbooks, especially those used in middle and senior high school science courses. The approach employed four aspects of scientific literacy to determine curriculum balance in textbooks. (KR)

Reports on the results of a conference of leaders in science education research held at the University of California, Berkeley, January 16-20, 1986. Describes the themes that emerged from the disucssions and makes four recommendations intended to encourage the development of an integrated research base in science education. (TW)

Visits to six school districts which were identified by the National Science Teachers Association's Search for Excellence program were made during 1983 by teams of 17 researchers. Their reports were analyzed in search for common characteristics that can explain the requirements necessary for excellent science programs. These characteristics are…

Applies Kuhn's model of the structure of scientific revolutions, Popper's hypothetic-deductive model of science, and Lakatos' methodology of competing research programs to a historical biological episode. Suggests using Kuhn's model (emphasizing the nonrational basis of science) and Popper's model (emphasizing the rational basis of science) in…

Discussed is the issue of the appropriateness of applied science approaches to evaluation in environmental education. The relationships between characteristics of applied science approaches to evaluation and the special characteristics of environmental education are explored. (Author/YP)

Discussed is the influence of the nature of the environment on the culture of a people and students' concept attainment in science. The influence of the home environment, reasoning abilities, and preference in type of learning are included in the discussion. (KR)

Reports on a study designed to focus on staff development delivery variables in the context of science teacher workshops. Data suggest that 8 to 16 hours is a minimum amount of time for staff development if teachers are to implement new strategies into their science classrooms. (TW)

Describes changes and effects of the Israeli paper-and-pencil matriculation examination in biology since first analysis in 1972. The examination has been significant for implementing an inquiry-oriented high school biology program based on the Biological Sciences Curriculum Study. Implications for upgrading science education are discussed.…

Investigated the problems chemistry majors have with learning distillation concepts in traditional chemistry laboratory courses. Reports that students take the generalized concepts at face value, construct decontextualized concepts for distillation, and cannot interpret their observations or make reasoned decisions based on the theoretical…
