Data from Colorado Adoption Project were used to examine hypothesis that association between parental divorce and children's adjustment is mediated by genetic factors. Findings for psychopathology were consistent with an environmentally mediated explanation for the association. Findings for achievement and social adjustment were consistent with a…

Examined environmental and gene-environment processes linking parenting (affect, control, responsiveness) and preschoolers' behavioral adjustment difficulties (noncompliance, conduct problems). Found that estimates of shared environmental variance and mediation were greatest for observational data, and estimates of child genetic variance and…

Argues that genetics, as popularized in "The Bell Curve" (Herrnstein and Murray, 1994), does not affect educational attainment and personal development, but environmental upheavals do. The environmental changes that effect educational and personal development are highlighted. It cautions that works involving pseudoscience, like "The…

Students' conceptions of three major artificial intelligence concepts used in the modeling of systems in science, fuzzy logic, neural networks, and genetic algorithms were investigated before and after a higher education science course. Students initially explored their prior ideas related to the three concepts through active tasks. Then,…

The Attuned Representation Model of eating-disorder etiology and symptom maintenance is a comprehensive model that can effectively guide prevention and treatment efforts by addressing individual, cultural, and interactive issues. The model integrates the risk factors related to the onset of eating-disordered behaviors (i.e., biological,…

This paper describes part of a project called Modeling Across the Curriculum which is a large-scale research study in 15 schools across the United States. The specific data presented and discussed here in this paper is based on BioLogica, a hypermodel, interactive environment for learning genetics, which was implemented in multiple classes in…

The current study elucidated the reasons for athletic performance differences between individuals who (1) engage in similar workloads, and (2) develop in similar environments. 8 elite and 11 sub-elite swimmers, with confirming data provided by 17 of their parents and 6 of their coaches, participated in this investigation. Findings revealed that…

Over the past decades, genetics has remained a difficult topic in school science. This paper presents an interactive multimedia program, "BioLogica", used to teach Grade 10 (14- and 15-year-olds) Australian students about genetics. Over six weeks, the teacher used different representations in the teaching and engaged students in computer…

One of the hottest areas of science today is the field in which biology, information technology,and computer science are merged into a single discipline called bioinformatics. This field enables the discovery and analysis of biological data, including nucleotide and amino acid sequences that are easily accessed through the use of computers. As…

Background: The present study was designed to investigate the association between visual exploratory behaviour in early infancy, novelty seeking in adolescence, and the dopamine D4 receptor (DRD4) genotype. Methods: Visual attention was measured in 232 three-month-old infants (114 males, 118 females) from a prospective longitudinal study using a…

Background: Autism is rarely diagnosed before three years of age despite evidence suggesting prenatal abnormalities in neurobiological processes. Little is known about when or how development becomes disrupted in the first two years of life in autism. Such information is needed to facilitate early detection and early intervention. Methods: This…

This analysis is about the role of poverty in school reform. Data from a number of sources are used to make five points. First, that poverty in the United States is greater and of longer duration than in other rich nations. Second, that poverty, particularly among urban minorities, is associated with academic performance that is well below…

We review the main findings of the Jyvaskyla of Dyslexia (JLD) which follows the development of children at familial risk for dyslexia (N = 107) and their controls (N = 93). We will illustrate the development of these two groups of children at ages from birth to school entry in the skill domains that have been connected to reading and reading…

In the first of two National Science Foundation (NSF)-funded workshops, 30 professors of biology and computer science from 18 institutions met at Wheaton College in Norton, Massachusetts, on June 6-7, 2002, to share ideas on how to incorporate genomics research into undergraduate curricula. The participants included nine pairs or trios of…

This article describes an extended collaboration between a development team and an evaluation team working with GenScope, an open-ended exploratory software tool. In some respects, this was a routine evaluation, documenting substantial gains (of roughly 1 SD) in genetics reasoning ability in all but 1 of 17 classes, despite challenges presented by…
