The purpose of this study was to analyze the errors made by students solving genetics problems. A sample of 10 non-science undergraduate students was obtained from a private college in Northern New Jersey. The results support prior research in the area of genetics education and show that a weak understanding of the relationship of meiosis to…

One of 16 booklets designed for use in an Open University course on the education of handicapped students in the United Kingdom, this document considers biological factors involved in handicapping conditions. An initial chapter examines the portrayal of disabled persons in drama, literature and film. Genetic involvement (autosomal dominant…

Fragile X syndrome is an inherited genetic condition identified by a break or a weakness on the long arm of the X chromosome, and associated with mental retardation. Described on this single-sheet information guide are the prevalence of fragile X syndrome, its increased rate of incidence in boys as compared to girls, physical characteristics,…

A critical review of Jensen's book which contains a reprint of the original controversial 1969 "Harvard Educational Review" article, 5 related articles by Jensen, and a bibliography of related articles. (EH)

Describes some uses of pocket-size electronic calculators in biology classes; for example, charting exponential population curves, evolution by natural selection, and random genetic drift. (PEB)

Contends that some of the gravest problems that minorities face today have their origins in the mususe of science and technology. Describes the activities of eugenicists; the treatment of children labeled hyperkinetic, and the most recent techniques of "psycho-surgery" aimed at curbing violence in those labeled mentally ill.

Reported are case histories of three severely retarded adolescents with typical Down's Syndrome features but whose cytogenetic analysis revealed a rare chromosomal anomaly of mosaicism of Down's and Turner's syndromes. (CL)

Examined were eight patients with cerebro-hepato-renal syndrome of Zellweger (associated with severe cerebral dysfunction, hypotonia and unusual appearance). (CL)

Based on a PhD dissertation submitted to Teachers College, Columbia University.

Text of The Second Annual Damon Lecture presented at the National Science Teachers Association Convention, Dallas, Texas, March 22, 1969

The paper refutes the long held belief that Down's syndrome is the result of maternal age and maternal etiology. The author cites new evidence which demonstrates that Trisomy-21 (the presence in the chromosome of an extra arcocentric chromosome resulting from non-disjunction), the major cause (95% of the cases) of Down's syndrome, can originate in…

The paper considers the future of education, particularly special education, in terms of theory. Reviewed is research in neurology relating to contra-lateral development in brain hemispheres, cephalo-caudal and caudal-cephalo myelination patterns or neural systems, and integration of neural patterns and neo-cortical control of the brain. Also…

This speech offers a brief description of Huntington's Disease (HD): its causes, symptoms, and incidence. It then concentrates on the psychological problems of persons one of whose parents had the disease, and the role of the counselor in helping these humans cope with their fears about contacting it themselves. A relatively detailed case study is…

Investigated were the feasibility and effectiveness of using programed materials with concomitant laboratory exercises in teaching genetics on the secondary level. Students from two white and two Negro high schools in the Atlantic Public School System participated, with one control and one experimental biology class in each school taught by the…

Material is discussed in articles by 40 contributors. Concerning physiopathogenesis of epilepsies there are introductory notes, two articles on genetics, one on neurophysiological and metabolic mechanisms, two on renal failure, a discussion of convulsive seizure and water intoxication, three articles on hypoglycemia, one on electroclinical…
