We engage in a metalogue based on eight papers in this issue of "Cultural Studies of Science Education" that review the state of conceptual change research and its possible affect on the teaching and learning of science. Our discussion addresses three aspects of conceptual change research: theoretical, methodological, and practical, as we discuss…

Summarizes teacher effectiveness literature and explores teaching-as-science and teaching-as-art, attempting to choose the best metaphor to describe the profession. The science-process metaphor has a better chance for improving teaching, though becoming a classroom scientist or researcher may be a difficult and lengthy process. Includes 24…

The author of a former paper (EC 600 327) responds to commentaries on her analysis of curriculum-based assessment and direct instruction in special education. The response focuses on the ideological basis of mechanistic thought in the study of human behavior, the shift toward holistic education, and use of scientific methodology. (JDD)

This review is organized under these headings: aims of science education; the image of science; why a philosophy of science; the nature of scientific knowledge and the role of theory; scientific method; practice of science by the community of scientists; and the role of practical work. (JN)

This commentary on a paper by L. Heshusius (EC 600 327) argues that, rather than rejecting empiricism, postmechanistic science embraces a more sophisticated view of empiricism and scientific method. The commentary also supports direct instruction with the use of multiple measures of educational progress, quantitative and qualitative alike. (JDD)

Discussed are two techniques that can be used to directly test the theory that the plates which make up the crust of the earth are still moving. Described are the use of satellite laser ranging and very long baseline interferometry. Samples of data and their analysis are provided. (CW)

This commentary on a paper by L. Heshusius (EC 600 327) describes key ideas of direct instruction and reflects on the original paper from a perspective that incorporates the realities of classrooms. The commentary calls for serious, systematic inquiry that explores instructional environments for special education students using constructs from…

Presented is a strategy which uses creationism and other pseudosciences as examples of non-scientific approaches to critical thinking to teach students the nature of science and the scientific method. Examples of the illogic of non-scientific approaches are given along with an explanation of how they can be used in teaching critical thinking to…

This article takes a critical look at practical work in school science and the often extravagant claims that are made for it. A case is made for a more rigorous, theory-driven approach to practical methods. (Author/CW)

Discussed are selected application and future trends in supercritical fluid chromatography (SFC). The greatest application for SFC involves those analytes that are difficult to separate using GC or LC methods. Optimum conditions for SFC are examined. Provided are several example chromatograms. (MVL)

Describes an experiment in which students are given a naturally occurring oligosaccharide as an unknown and are asked to determine both its monosaccharide composition and its structure. Discusses methods and experimental techniques including thin layer chromatography and the use of enzymes. (CW)

There are two major concerns about the teaching of high school biology. One is the degree to which students memorize laws, facts, and principles, and the second involves the role of the classroom teacher. These aspects result in a discrepancy between the theory and practice of science education. The purpose of this report is to provide: (1) a…

Documents the educational use of spreadsheets through a description of exploratory work which utilizes spreadsheets to achieve the objectives of Conway's Game of Life, a scientific method game for the development of problem-solving techniques. The implementation and classroom use of the spreadsheet programs are discussed. (MBR)

Describes a teaching activity that improves students' scientific reasoning by focusing attention on the causal, explanatory nature of psychological theories. Students learn and use an argument form called Inference to the Best Explanation (IBE). Includes examples of this technique and student responses to the course. (MJP)

Follows an experimental program where 30 trained high school science teachers used 6 to 10 students each to produce an original experimental environmental research project. Offers suggestions to improve science in high schools. Lists methodology of several of the projects and describes others. (ML)
