A method of analyzing the content of biology/curricula, courses, and texts on the basis of the relative emphasis on different levels of biological organization, is discussed. It is suggested that this method may have led to unwarranted contrasts between traditional and modern curricula. A simple modification is proposed. (Author/BB)

Compares the content of some undergraduate and graduate courses in chemical kinetics and chemical reactor engineering. (BB)

Elementary and junior high school science textbooks were analyzed for the presence of prerequisite topics on evolution (protoconcepts). Results indicated that coverage of evolutionary protoconcepts varies considerably among published textbooks. Recommendations for teacher analysis of textbooks are provided. (ZWH)

Discusses the reactivity of aryl halides with nucleophilic or basic reagents, including nucleophilic attacks on carbon, hydrogen, halogen, and arynes. Suggestions are made concerning revisions of the sections on aryl halide chemistry courses and the corresponding chapters in textbooks. (CC)

Background, rationale, and promising practices for teaching about science-related social issues in the science and social studies classroom are presented. Material is divided into five sections, each introduced with a topical question. The first section considers the challenges associated with the pervasive influences of science and technology in…

Lists polymer chemistry topics and depth of topics to be covered in general chemistry courses. Also lists topics using polymers as tools for delivering necessary concepts, discussing 11 topic areas. List of readings, information on textbook evaluation, and illustrative examination questions are included. (JN)

Reports on a study designed to examine selected units of commonly used elementary science texts, using the Project Synthesis goal clusters as a framework for part of the examination. The discussion of the finding focuses on the comparison of the results to recommendations of the National Science Teachers Association (NSTA). (TW)

Argues that introductory courses in college biology do a poor job of encouraging students to enter a career in biology. Cites examples of poorly written textbooks and treatments of various aspects of biology including basic definitions, cells and their operations, the mechanics of life, the nervous system, evolution and sex. (TW)

Compares two methods of teaching in two grade seven science classes in Ontario (Canada) that illustrate how students can attain different sets of objectives while mastering the same subject matter topic. Shows how different sets of classroom events can be interpreted in terms of differing curriculum emphases. (Author/LC)

Perspectives on contemporary creationism are offered and the effects of that movement on public education are examined in this collection of articles. Six papers address concerns related to: (1) the detrimental impact of creationism on the teaching of science and on the understanding of the natural sciences; (2) efforts in confronting creation…
