Based on the view that individual variability is best understood as the result of influences from multiple domains operating over time, this book describes how different domains of influence operate, describes the operating processes in common to the different influences, and shows how these processes meet the criteria for a full-fledged system.…

Our main goal in this study was to explore whether the use of models in molecular genetics instruction in high school can contribute to students' understanding of concepts and processes in genetics. Three comparable groups of 11th and 12th graders participated: The control group (116 students) was taught in the traditional lecture format, while…

The classic ("status attainment") model of educational and occupational attainment suffers from three related shortcomings when used as a tool for comparative or policy-oriented research on social mobility: (1) ambiguity of model parameters as measures of opportunity for achievement vs. ascription; (2) vulnerability to incomplete specification of…

In only recent history, illicit use of methamphetamine, once isolated to urban areas on the West Coast, has spread into rural areas of the Midwest and southern United States. Although past and current methamphetamine legislation has increased penalties for methamphetamine manufacturers and tightened restrictions on sales of known precursors, the…

This uniquely comprehensive and current survey of the research in science education has been compiled by the most prominent experts in the field. More than a summary of findings, the content of this comprehensive single volume provides an assessment of the significance of research; evaluates new developments; and examines current conflicts,…

This monograph is the first attempt to collect and share some of the teaching techniques, activities, and ideas of former recipients of the Outstanding Biology Teacher Award. The lessons are organized into topical themes to facilitate their incorporation into standard curriculum. The manual is divided into two main sections, "Labs" and "Ideas."…

Abstracts and abstractors' critiques of six science education research studies and two responses to critiques are presented in this journal issue. Each of the studies addressed some aspect of instruction. Areas investigated include: (1) the effects of teacher-demonstration as compared to those of self-paced instruction on student achievement; (2)…

Abstracts and abstractors' critiques of eight science education research studies and two responses to critiques are presented in this journal issue. Each of the studies reviewed focused on a different research theme. Topics addressed include: (1) validation of a learning hierarchy for the mole concept; (2) transfer of learning with emphasis on…

The eight working papers presented in this compendium were prepared for the National Science Foundation (NSF) as one means to assist the Office of Science and Technology Policy with preparation of the Administration's Annual Science and Technology Report to the Congress, 1981. They focus on specific aspects of three central themes directly related…

Twenty-eight papers examine basic theories and clinical methods in child psychiatry. Theories and methods discussed concern child psychiatry and the World Health Organization, pediatrics, child disturbances, observation, the psychodiagnostic approach, longitudinal research in child development, the comparative approach to early child development,…

The present study examined the effect of consanguineous marriage in the Arab community on reading disabilities of offspring. It examined whether the rate of reading disabilities was higher among offspring of first-cousin parents than offspring of unrelated parents; and whether reading-disabled children of first-cousin parents were more disabled in…

Purpose: This study examined (a) the extent of genetic and environmental influences on children's articulation and language difficulties and (b) the phenotypic associations between such difficulties and direct assessments of reading-related skills during early school-age years. Method: Behavioral genetic analyses focused on parent-report data…

In order for schools to help students with learning difficulties and disabilities improve their achievement in mathematics, educators, researchers, practitioners, and policymakers need a better understanding of the evidence based on what is behind these students' difficulties in learning math. That is just what they will get with this landmark…

This paper reviews the research on fragile X syndrome, the second most common cause of mental retardation related to chromosomal anomaly. It notes that far more males than females are affected by the fragile X syndrome, which typically results in craniofacial changes, delays in growth and development, speech/language difficulties, and cognitive…

The Interactive Genetics Tutorial (IGT) project and the Intelligent Tutoring System for the IGT project named MENDEL supplement genetics instruction in biology courses by providing students with experience in designing, conducting, and evaluating genetics experiments. The MENDEL software is designed to: (1) simulate genetics experiments that…
