The article examines recent developments in seizure mechanisms and management in young children. Emphasis is directed toward neurodevelopmental sequelae and important genetic/environmental influences. (Author)

Discusses the human, plant and animal, and industrial dimensions of biotechnology, focusing on current uses in such fields as: (1) genetics; (2) electronics; (3) prosthetics; (4) drugs; (5) agriculture; and (6) the environment. (JN)

Examined the problem-solving performances of novices (11 undergraduates) and experts (9 graduate students and instructors), comparing them in terms of background expertise and problem-solving success. Also examined problem-solving behaviors reported in other domains and determined whether or not genetics is a fruitful area for problem-solving…

Physical, psychological, and cytogenic characteristics of individuals with the Fragile X syndrome are reviewed. Prospects for therapy with folic acid, prenatal diagnosis, phenotype of heterozygote for the marker X, and unresolved issues about the syndrome are discussed. (CL)

Research in the genetics of behavioral traits, undertaken by family studies, twin studies, and adoption studies, has revealed information on normal variation in cognitive abilities as well as specific learning disabilities (primarily dyslexia). Genetic evaluation of learning disabled students have implications for counseling and recurrence risk…

Reviews recent books on science for readers from age nine through young adult grouped according to the following categories: astronomy, computers, electronic musical instruments, and genetics. (RBW)

Studies by the late English psychologist Cyril Burt of IQ scores of separated twins strongly suggested that intelligence was inherited. A summary of recent research costs doubt upon the validity of Burt's work. (SL)

Modern technology in life and health sciences brings a new understanding to the study of cells and as a result, the National Science Education Standards emphasize understanding of science and technology. This ERIC Digest describes the central role of cell biology (cytology) in understanding these areas and explains conceptual difficulties and…

Some concepts in genetics are difficult for many students to understand. This document provides hands-on, cost efficient, fun activities for students to help them better understand abstract concepts in genetics. Each activity includes: purpose, introduction, materials, procedures, results and conclusion. Some of the topics explored are: (1)…

This guide presents a module for college students on ribonucleic acid (RNA) and its role in biology. The module aims to integrate the latest research and its findings into college-level biology and provide an opportunity for students to understand biological processes. Four activities are presented: (1) "RNA Structure: Tapes to Shapes";…

This digest explains how to inform high school students and their parents about the human genome project (HGP) and how the information from this milestone finding will affect future biological and medical research and challenge science educators. The sections include: (1) "The Emerging Legacy of the HGP"; (2) "Transforming How…

Many teachers avoid controversial topics because they do not want to upset students or parents, do not know appropriate instructional strategies, and fail to recognize the importance of motivating students through placing science in its relevant context. An example is provided for use in a methods course for helping future high school teachers to…

Presents opposing philosophies relating to the nature of aggression in man. One position advocates that human aggression is the product of evolution and is inherited, while the other proposes a cultural pattern model of aggression and uses two empirical tests in an attempt to disprove the genetic model.
