Described are simulations that can be used to illustrate evolution by natural selection. Suggestions for simulating phenomena such as adaptive radiation, color match to background and vision of predators are offered. (BR)

Reviews the methods being utilized to teach Darwinism in English schools. (SL)

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.

DEVELOPED AND SUBJECTIVELY EVALUATED ARE INSTRUCTIONAL MATERIALS FOR USE IN AN INTRODUCTORY COLLEGE LEVEL GENERAL EDUCATION BIOLOGY COURSE, WHICH EMPHASIZES THE DYNAMIC AND INVESTIGATIVE ASPECTS OF SCIENCE. THE MATERIALS, WHICH USE A CASE HISTORY APPROACH, WERE DEVELOPED BY EDITING EXCERPTS FROM CLASSICAL SCIENTIFIC PAPERS WITH ADEQUATE EDITORIAL…

Two teaching aids, on space flight and on natural selection and evolution of beaks in birds, are described. A simulated space instrument plaen was made and a space launch and other functions carried out. A simple experiment with match sticks was used to teach natural selection. (PS)
