Urges science teachers to consider the affective domain and to seek affective goals in teaching environmental topics. Suggests that biology and other science courses should adopt, as much as possible, the concepts of environmental education. (JR)

Discusses the procedures that should be observed in constructing a dichotomous key. The keying exercise described was used as a laboratory activity in a biology course for elementary education majors, however it could be used in other courses. (JR)

Describes a high school biology exercise in which a computer greatly reduces time spent on calculations. Genetic equilibrium demonstrated by the Hardy-Weinberg principle and the subsequent effects of violating any of its premises are more readily understood when frequencies of alleles through many generations are calculated by the computer. (JR)

Describes a hydroponic culture technique suitable for student exercises in biology. This technique of growing plants in nutrient solutions enhances plant growth, and is an excellent way to obtain intact plants with root systems free of soil or other particulate matter. (JR)

Discusses the results of the National Assessment of Educational Progress survey of knowledge, skills, and attitudes in science. Reports and comments on the findings relating to black students, sex differences, geographical differences, parents' education, and neighborhood influences. Summarizes some of the broad implications of the study for…

Describes the ERAT (electronic-response and audiotutorial modes of instruction) system which is used to teach biology to non-science majors at Ball State University. Outlines the course content, the student activities involved in using this system, the role of the instructor, and the value of technology in education. (JR)

Describes a course in microbiology offered as a high school science elective. The laboratory-oriented course has proved to be very popular and provides students with the basic techniques for handling equipment and working safely with bacteria. (JR)

Examines the legal and constitutional implications of the fundamentalist movement to win equal time for creation doctrine in science and biology textbooks. (JR)

Clarifies the difference between the Piagetian Conservation of Liquid Quantity task and the Conservation of Volume task and provides an alternative test for the presence of formal operational thought. (JR)

Describes the appalling conditions associated with many zoos and with the trafficking of exotic pets, and discusses recent federal and international measures designed to reduce the abuse of wild animals. (JR)

Describes the sturcture and asexual reproduction of the fungus Pilobolus and outlines a number of experiments with this organism that are suitable for secondary school biology students. (JR)
