Considers advantages of teaching chromosomal aspects of meiosis before introducing principles of Mendelian genetics. (AL)

Describes the revision of a college biology sequence, and outlines the content of some courses in the core. (AL)

Describes sequence of activities for teaching three-point linkage concept and gene-mapping to high school biology students. Includes laboratory experiments and hypothetical examples for classroom discussion. (PS)

Describes a procedure for making slides of microsporogenesis in Tradescantia. Uses photographs to demonstrate that Tradescantia is an ideal organism for studying meiosis in the classroom. Contains 17 references. (JRH)

Describes different sources of readings for understanding issues and concepts of genetic engineering. Broad categories of reading materials are: concerns about genetic engineering; its background; procedures; and social, ethical and legal issues. References are listed. (PS)

Background information, laboratory procedures (including matings performed), and results are presented for an open-ended investigation using the fruitfly Drosophila melanogaster. Once data are collected, students develop hypotheses to explain results as well as devise additional experiments to test their hypotheses. Calculation of chi-square for…

Reports the results of a questionnaire sent to 194 teachers. Questions included percentage of teachers using specified genetics topics in the classrooms and responses of the teachers to sixteen value-laden statements. Results indicate a need to refocus science teaching to emphasize the interface between biology and society. (MA)

Establishes a rationale for teaching population genetics to students and inservice biology teachers. Suggests strategies for introducing students to the Hardy-Weinberg principle. (MDH)

Reports an investigation designed to determine if using programmed textbook units in rather typical courses improved student test performance and enriched student interaction in class discussion. (PEB)
