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)

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)

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.

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)
