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…

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)

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)

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.…

Examined instructional materials, teacher planning, instruction, and student conceptions related to an activity unit on plants and photosynthesis. Reasons are offered about why the teacher was unsuccessful in helping students replace their misconceptions with scientific conceptions, although the teacher knew this misconception existed. (JN)

Examined is the influence and developmental nature of science processes. Results indicated that a one-semester process skills course was effective in developing a basis for science content acquisition. Additional gains can be obtained in an extended curricular sequence. (Author/CW)

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)

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)

More than 1,600 middle school students, including an experimental group exposed to the Biological Science Curriculum Study (BSCS), were administered the Modified Nature of Scientific Knowledge Scale. Results indicate that the students utilizing the traditional science curriculum possessed a significantly better understanding of the testable nature…

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…

Science education standards established by American Association for the Advancement of Science (AAAS) and the National Research Council (NRC) urge less emphasis on memorizing scientific facts and more emphasis on students investigating the everyday world and developing deep understanding from their inquiries. These approaches to instruction…
