This book is a compendium of papers presented March 18-20, 1996, at the eighteenth annual Spectrum of Developmental Disabilities course. Research findings are presented that address identification, diagnosis, management, and prognosis of specific reading disability. Individual chapters include: (1) "Dyslexia: The Evolution of a Concept" (John…

This lesson for grade 12 is designed to raise student awareness of the potential of human cloning and of the effects it could have on the present, naturally born population. Students work in teams to research the issue and are provided with background information, detailed instructions, on-line resources, and reflection questions. The teacher's…

This curriculum module explores genes, environment, and human behavior. This book provides materials to teach about the nature and methods of studying human behavior, raise some of the ethical and public policy dilemmas emerging from the Human Genome Project, and provide professional development for teachers. An extensive Teacher Background…

A reply to Plomin's critique and some criticisms of Munsinger's review of adopted child literature are presented. Selective bias in adoptee samples, implicit assumptions in models that lead to heritability estimates, and problems produced by lack of an accepted model of environmental transmission are also discussed. (Author/RD)

A study involving 356 twin pairs with early language delay found environmental influences shared by both twins were more substantial than genetic factors. Heritability was significantly higher in those with persisting difficulties but only when assessed in terms of parental concern at 3 years or professional involvement at 4 years. (Contains…

This article focuses on methods useful for identifying differences in the development of language reading abilities in children that rely on measures of brain responses and behavioral assessments. Findings from these methods are described and indicate that even behaviors strongly influenced by biological mechanisms can be influenced through…

A paper model which is designed to give students a hands-on experience during lecture and blackboard instruction on DNA structure is provided. A list of materials, paper patterns, and procedures for using the models to teach DNA structure and replication are given. (CW)

Seven papers present international perspectives on the relationship between education and child development. Conclusions reached in research on developmental genetics, cognitive development, and classroom instruction are considered, characterizing the current state of knowledge with respect to the influence of education on achievement outcomes.…

Contrasted are DNA viruses, RNA viruses, and RNA retroviruses. The structure, genome, and replication of retroviruses are discussed. The discovery, structure, and action of the HIV virus are described. A list of 17 references is included. (CW)

Reviews research on the heritability of intellectual factors, personality factors, and psychopathology. Discusses the importance of investigating within-family environmental differences in order to understand the environmental origins of individual differences in development. (Author/BJV)

Reports on the teaching of recombinant DNA technology in high school biology courses. Explains reactions of the public, students, and colleagues to the molecular genetics unit. Indicates equipment, curricular materials, training, workshops, and availability. (RT)

Describes the "special destiny-special faculty" paradigm that has dominated western thinking about the nature and origins of language and argues instead that language systems are like technologies and that language acquisition and use involves a range of capacities and skills, a view that could be called the "mosaic development…

Genetics, family dysfunction, separation/loss, learning disabilities, and lack of social support in school place adolescents at risk for depression. The article shares evidence that documents a link between structured cooperative learning and the resulting stronger social support relationships that evolve as peers help support, respect, and trust…

The Genetics Construction Kit is a computer-based learning tool that simulates the phenomena of classical transmission genetics. Its construction kit approach lets users set the parameters of the problem sets to be generated. The program has been used extensively in science education research and curriculum development. (Author/MSE)

Urges educators and citizens to ignore the hype surrounding "The Bell Curve" and to grasp the ethnocentrism (or racism) that underlies eugenicist arguments. Both Carnoy and Ladson-Billings offer hope to those supporting educational equity and the appreciation of diversity. (SLD)
