Hill, L. – Journal of Biological Education, 1985
The limits of falsification are discussed and the historically based models of science described by Lakatos and Kuhn are shown to offer greater insights into the practice of science. The theory of natural selection is used to relate biology to philosophy and scientific method. (Author/JN)

Thompson, K. – Journal of Biological Education, 1985
Study of buried seed banks (viable seeds deposited in the soil near parent plants) provides a relatively easy way of determining cumulative effects on seed production and species' altitudinal limits. Sites, methods, validity, interpretation, problems of collection on a mountain, and germination techniques are discussed. (Author/DH)

McDermott, J. – Journal of Biological Education, 1985
Describes a computer program that students use to check their suggestions of possible lines of investigation during a microbiology exercise, the results of procedures, and the decisions made on the basis of experimental evidence. Effectiveness of the program and practical aspects of the investigation are considered. (DH)

Kinnear, Judith F. – Journal of Biological Education, 1986
Focuses on genetic concepts that form key components of transmission genetics and illustrates how the domestic cat can be used in the teaching of these concepts. Offers examples of how laboratory experiences with the cat can enhance student learning of genetics. (ML)

Calver, M. C.; Porter, B. D. – Journal of Biological Education, 1986
Presents information that gives a methodological background to the concept of food webs. Stresses the importance of calibrated techniques in ecological research and explains direct methods for studying animal diets. Exercises for gathering first-hand data on bird diets and analyzing secondary data on mammal diets are suggested. (ML)

Seymour, Jerry; Longden, Bernard – Journal of Biological Education, 1991
Reports results of procedures directed at isolating and identifying students' difficulties in comprehending the concepts involved in lessons about gas exchange and respiration. Indicates that pupils (n=137) had deficient understanding of prerequisite concepts and tended to operate at the concrete operational level, whereas the highly abstract…

Okebukola, Peter A. – Journal of Biological Education, 1984
Examined the effectiveness of cooperative, competitive, and individualistic interaction patterns in promoting acquisition of science process skills during biology laboratory activities. Results (from 720 secondary students--352 girls and 368 boys) show that competitive interaction was superior to cooperative and individualistic interaction…
