Explains a method to enable students to understand DNA and protein synthesis using model-building and role-playing. Acquaints students with the triplet code and transcription. Includes copies of the charts used in this technique. (DDR)

Uses the case study approach to introduce students to the relationship between science and society. Develops an awareness of ethics, specifically on DNA research, through computer simulations and Internet conferencing. (Contains 20 references.) (YDS)

Details a project in which successful DNA analysis techniques were developed by students and their teacher in a rural school. Focuses on a study of sage grouse. (DDR)

Presents a protocol that gives students hands-on experience in generating a meaningful physical map of a circular molecule of DNA. Topics include agarose gel electrophoresis, logic of restriction maps, extracting data from an agarose gel, managing data from gels, experimental protocol, loading gels, electrophoresis, photographing gels, collecting…

This address examines the future of biobehavioral science and the opportunities and pitfalls it holds for individuals with intellectual and developmental disabilities. Examples of recent advances in genetics and neurosciences are discussed, as well as opportunities that these advances hold for understanding the effects of the environment on…

This commentary reviews forthcoming articles on the scientific study of dyslexia, genetic and neurophysiological aspects of dyslexia, cross-linguistic aspects of literacy development and dyslexia, and theory-based practice. It concludes that educators should continue to strive to promote theory-based research and evidence-based practice to achieve…

Described is a study which was developed to find the proportion of cross-dominance in young adults. Procedures and statistical tests are discussed. The tasks used in the assessment of cross-dominance are described. Results indicated that all persons suffered from some cross-dominance. (CW)

Presented are several ideas for projects involving ladybird beetles. Discussed is background information about the insects; and projects involving life histories, intra-specific variation, taxonomy, genetics, behavior, ecology, habitat surveys, population biology, and overwintering biology. Lists 12 references. (CW)

Describes how the science fiction novel "Jurassic Park" has been used to provide the focus for summate discussions among gifted high school students participating in a state-sponsored, science-intensive summer program. Discusses adaptations of this approach for use in chemistry classes from the high school to intermediate college level. (JRH)

Describes new software called "PopGenetics" that is useful for conducting hands-on laboratory activities that illustrate population genetics. Users investigate the effects of selection and random drift on changes in allelic frequencies, the effect of mutation, and interactions among these three parameters. Designed for use on Macintosh…

Reports results of a study that examined academic library holdings for core journals in genetics and economics to identify quantitative and qualitative journal characteristics that are predictors of the number of libraries subscribing to the journal. Variables investigated include subject area, publisher, price, longevity, impact factor, prestige…

Triads composed of a mother and two children from either a nonadoptive or an adoptive family were observed in play settings in the home. Genetic factors were found to influence differences in sibling interactions and maternal interactions with siblings. Environmental factors also had an influence. (BC)

This article presents a case study of a child with Hunter's syndrome, a genetic disorder often resulting in a degeneration of speech and language functioning and hearing loss. The study demonstrates the typical delay in diagnosis and shows how a team approach can maintain such a child in a regular public school setting. (Author/DB)

Discussed are the division of labor, defenses, genetics and evolution, communication, and navigation power of honeybees. The scientific and cross-curricular themes that can be offered using the economically important honeybee are described. Research that suggests that bees may be flying magnets is also discussed. (KR)

Presents summary of a panel discussion at the Conference of the North American Association for the Study of Obesity (1992) on the health risks of treating obesity. The panel focused on selectivity in accepting patients, obesity and mortality, genetic individuality, weight loss mode and outcome, weight loss and longevity, and weight maintenance.…
