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 paper describes the development and evaluation of a blended learning resource in the biosciences, created by combining online learning with formal face-face lectures and supported by formative assessments. In order to improve the effectiveness and efficiency of teaching large classes with mixed student cohorts, teaching was delivered through…

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…

This document presents the priorities of Action for Prevention, Inc. for the prevention of developmental disabilities in Virginia in the 1990's. The priorities were selected from recommendations developed by four task forces on genetics, perinatal, early childhood, and school age/adolescence. The document is intended to contain recommendations…

This paper focuses attention on the kinds of research assumptions that are present in the literature on language, and which can be found in the "myths" about family structure and motivation. Three major professions are concerned with describing the language and cognitive abilities of black children--(1) educators, who believe these…
