Flow-diagrams, algorithms, decision logic tables, and concept maps are presented in detail as methods for teaching practical procedures, problem solving, and basic concepts in microbial genetics. It is suggested that the flexible use of these methods should lead to an improved understanding of microbial genetics. (Author/MA)

Describes benefits and techniques for utilizing Mormoniella vitripennis (jewel wasps) in teaching biology. Feeding, courtship, egg-laying, and insect behavior investigations are presented. (SL)

Reviews a fictitious case study used as a values-clarifying teaching strategy for students of human genetics and bioethics. (SL)

To further practitioners' understanding of shyness, this review of research discusses (1) origins of shyness, (2) cognition and shyness, (3) situational factors affecting shy behavior, (4) social difficulties of shy children, (5) shyness and sex differences, (6) persistence of shyness, and (7) ways for caregivers to help the shy child. (RH)

Discusses one mechanism proposed for the two-step initiation/promotion scenario of the development of cancer called oncogenes and a possible alternate mechanism that may prevent tumors from developing. Uses the example of retinoblastoma to illustrate the mechanisms. States that these mechanisms may not be caused by the activation of oncogenes. (CW)

IQ scores from five kinship categories of 7- to 12-year-olds were analyzed into genetic and environmental components. The common environmental effects were larger for older children than younger children. Overall, the Genetic and Common Environment Sources each accounted for approximately 40% of the IQ variability in the data. (Author/LMO)

The present study is a behavioral genetic analysis of specific cognitive abilities in early childhood. Parent-offspring data for adopted children and nonadopted children in the Colorado Adoption Project were used. Significant correlations were found between biological mothers' IQ and the IQ of offspring, but not for specific cognitive abilities.…

Compares the spelling errors on the Wide Range Achievement Test II made by adults with an apparent autosomal dominant form of dyslexia to those made by their normal adult relatives and by spelling-age matched normal controls using a computerized error evaluation program. (HOD)

Presents aims and objectives for a genetics course and indicates potential difficulties in teaching this subject area. Offers methods for determining and dealing with these difficulties and outlines assessment strategies for the cognitive, affective, and psychomotor areas. (ML)

Provides activities (and program listings) related to a Mendelian genetics experiment, Tetranacci numbers, and Pascal loops. Also suggests using the computer and spreadsheets to plan the production of a school yearbook. (JN)

Discusses the main ethical issues generated by the new genetics and suggests ways to think about them. Concerns include "playing God," violation of the natural order of the universe, and abuse of genetic technology. Critical distinctions for making difficult decisions about genetic engineering issues are noted. (DH)

Describes the use of a chart that systematically summarizes three basic steps that involve DNA and its decoding in both eukaryotic and prokaryotic cells: replication; transcription, and translation. Indicates that the chart (mounted on a tranparency) does an adequate job of conveying basic information about nucleic acids to students. (DH)

Presents an overview of the volunteer-taught "Omnibus" enrichment program implemented in Windsor, Colorado, to meet the needs of academically gifted elementary students. Outlines lesson plans and activities for a six-week, hour-long course on genetics for fifth graders. (NEC)

Research indicates some early life stresses can have a profound impact, resulting in changes in brain function and behavior, and even differences in the ways some genes express their particular genetic code signature. At various times during early development, different neural systems appear to have an increased sensitivity to stress and can…

The publication of "The Bell Curve" by R. Herrnstein and C. Murray enraged many with its contention that black children are genetically less able to learn because of their race and its suggestions that some groups may be less worthy of the expenditure of attention and resources because of a reduced capacity for education. This collection…
