Retrospective longitudinal data on 21 boys with the fragile X syndrome were analyzed. Results indicated that 13 of the boys showed a significant decline in intelligence quotient at retest, suggesting that while young boys with this syndrome may be only mildly retarded, adults are usually moderately to severely retarded.

Suggests a new experiment to study the genetic material of eukaryotes. It is based on the rapid growth and interest of the research on chromatin. (TW)

Discusses the following in relation to their predictability to future drug abuse in youth: (1) susceptibility of children of chemically dependent parents; (2) genetic transmutation; (3) family structure and management; (4) socialization; and (5) cognitive family characteristics. (Author/LHW)

An interactive computer program in microbial genetics is described. The simulation allows students to work at their own pace and develop understanding of microbial techniques as they choose donor bacterial strains, specify selective media, and interact with demonstration experiments. Sample questions and outputs are included. (DH)

Describes a microcomputer program (written for the Apple II+) which can serve as a lecture demonstration aid in explaining genetic transcription and translation. The program provides unemotional information on student errors, thus serving as a review drill to supplement the classroom. Student participation and instructor options are discussed. (DH)

Three high school biology textbooks were analyzed to determine possible sources of misconceptions and related learning problems associated with genetics. Misconceptions were examined in these categories: conceptual organization; conceptual relations; use of terminology; and mathematical elements. Implications for instruction related to each…

Offers perspectives on natural selection and the phenomenon of altruism. Presents evidence for and against the theories that evolution acts essentially on genes, on individuals, on kin, or on larger groups. (ML)

Investigated common belief patterns secondary school students (N=84) have about inheritance, noting the most prevalent misconceptions about genetics which occur at different age levels. Implications based on findings and suggestions for teaching lower secondary courses are included. (ML)

The advantages of DNA hybridization procedures for classroom and clinical use can now be realized by the recent development of nonradioactive DNA labeling/detection procedures. These methods (which are described) can replace the use of isotopes in standard DNA hybridization procedures. (JN)

The educational design of a project option in an Open University course on evolution is described. Also described is the simulation which models the genetic and evolutionary consequences of two populations of a species of flowering plant coming together after a period of genetic isolation. (Author/JN)

Presented are five science teaching ideas including: (1) a method for anesthetizing frogs with Finquel, (2) a demonstration of gene drift utilizing poppet beads, (3) description of a successful school arboretum project, (4) the use of acrylic plastic for making science laboratory equipment, and (5) a description of a model cell made from Baggies.…

The integration of History in the educational practice can lead to the development of a series of activities exploiting genetic "moments" of the history of Mathematics. Utilizing genetic ideas that developed during the 14th century (Merton College, N. Oresme), activities are developed and mathematical models for solving problems related to uniform…

This study of creative genius argues that creativity can best be understood as a Darwinian process of variation and selection. The artist or scientist generates a wealth of ideas, and then subjects these ideas to aesthetic or scientific judgment, selecting only those that have the best chance to survive and reproduce. The book draws on the latest…

This 23-minute videotape for grades 5-8, presents the myriad of animal life that exists on the planet. Students can view and perform experiments and investigations that help explain animal traits and habits. The story of evolution starts with the study of fossils that helps scientists link today's living organisms with those of the past. Students…

Today, homosexuality has become a topic of discussion throughout the psychological community and society at large. However, there is great controversy about the etiology of homosexuality and more specifically, lesbianism. This paper describes a review of the literature to examine the hypothesis that a multitude of factors may influence the…
