The incidence of recurrent mongolism was analyzed among, 2,331 mongol propositi (and their 6,225 sibs) in 34 British institutions and daycare centers. (BB)

A parent-offspring adoption path model, with a measured index of the home environment, was developed to assess extent to which genetic and environmental influences of the parents affect relationships between the environmental index and children's behavior. Intelligence Quotient (IQ) data from the Colorado Adoption Project were used. The…

The study examined preference for social gaze, percentage occurrence of social gaze, nonverbal social avoidance, and nonverbal repetitive behaviors. Prepubertal males with the fragile X syndrome (N=12) demonstrated a higher overall percentage of avoidance for both parent and strangers than handicapped (autistic and Down Syndrome) and…

The present study points out problems in the model, indices of familiality, and design used by Benbow, Zonderman, and Stanley in a study of precocious children and their parents. (Author/LMO)

Presents an overview of a genetics course including explanations of major concepts, principles, and sequencing methods. Describes the typical participating student's background and prior knowledge level. Appendices contain a list of terms and three concept maps. (ML)

Evaluated Bannatyne's genetic dyslexic subtype of reading disability using Wechsler Intelligence Scale for Children-Revised data from 140 disabled readers and matched controls. Although a familial pattern of reading problems was present among the relatives of the disabled readers, it was not unique to the genetic dyslexic subtype. (JAC)

Presents information on the teaching of nutrition (including new information relating to many current O-level syllabi) and part 16 of a reading list for A- and S-level biology. Also includes a note on using earthworms as a source of material for teaching meiosis. (JN)

The choice between genetic and environmental explanations is most properly based on "jointly genetic/environmental designs," which control for both genetic and environmental differences in a behavior genetic framework. (Author/GC)

A laboratory experiment that involves solving problems with conflicting evidence or inconsistent data. The experiment gives students opportunities to reason as scientists. (EB)

A graduate program at Sarah Lawrence College is designed to bridge the gap between the medical community with its advanced knowledge of genetics and couples facing hereditary diseases or handicaps. The aim is to train these middle-level professionals to counsel couples. (LBH)

Provided is a summary of the 26th Pugwash Conference on Science and World Affairs held August 26-31, 1976, in Muhlhausen, East Germany. World problems discussed included: arms limitations, military research and development, nuclear test ban, alternative energy sources, and genetic engineering. (SL)

This paper describes the GenScope Assessment Project, a project that is exploring ways of using multimedia computers to teach complex science content, refining sociocultural views of assessment and motivation, and considering different ways of reconciling the differences between these newer views and prior behavioral and cognitive views. The…

The new advancement in genetics and reproductive technologies is one of the most relevant controversial topics concerning students in science education today. This study investigates the role of teachers in providing an environment for students in which they can interchange ideas and discuss ethical issues in science classrooms. This study…

This paper describes a study of high school students' participation in the construction and revision of explanatory models as they attempted to account for a variety of inheritance phenomena observed in computer-generated "fruit flies". Throughout the course students were encouraged to explore epistemological issues related to the assessment and…
