Direct linkSafuanov, Ildar S. – International Journal of Mathematical Education in Science and Technology, 2005
In order to teach on the basis of the genetic approach, one should undertake an analysis consisting of the following two stages: (1) a genetic elaboration of the subject matter and (2) an analysis of the arrangement of the material, including a consideration of various ways of representing it and its effect on students. The genetic elaboration of…

Cooper, Richard S. – American Psychologist, 2005
During the last hundred years, the debate over the meaning of race has retained a highly consistent core, despite evolution of the technical details. Non-Europeans, and in particular, Africans, are assigned the role of deviants and outcasts, whose claim on our common humanity remains in doubt. Each time the technical facade of these racialist…

Lopes, O.; Barton, G.; Morgan, J. – Journal of Intellectual Disability Research, 2005
The clinical features of this rare chromosomal syndrome are described in two individuals. Our limited knowledge of the natural history of this disorder has made it difficult to counsel parents as well as outline specific treatment and management plans. Interviews were undertaken with subjects, carers and next of kin, and the literature was…

Mustapha, Y.; Muhammad, S. – Educational Research and Reviews, 2006
The assembly of proteins takes place in the cytoplasm of a cell. There are three main steps. In initiation, far left, all the necessary parts of the process are brought together by a small molecule called a ribosome. During elongation, amino acids, the building blocks of proteins, are joined to one another in a long chain. The sequence in which…

Two mutations in the DJ-1 gene on chromosome1p36 have been identified recently to cause early-onset, autosomal recessive Parkinson's disease. As no information is available regarding the distribution of DJ-1 protein in the human brain, in this study we used a monoclonal antibody for DJ-1 to map its distribution in frontal cortex and substantia…

Hermann, Gilbert – American Biology Teacher, 2003
Molecular genetics is a rapidly changing field with new developments almost from day to day. One interesting hypothesis that has come from everyone's ability to sequence proteins and/or genes is that of the molecular clock. This hypothesis postulates that homologous sequences of DNA and thus macro molecules evolve at a constant and invariable rate…

Nettle, Daniel – American Psychologist, 2006
A comprehensive evolutionary framework for understanding the maintenance of heritable behavioral variation in humans is yet to be developed. Some evolutionary psychologists have argued that heritable variation will not be found in important, fitness-relevant characteristics because of the winnowing effect of natural selection. This article…

Ben-Nun, Michal Stolarsky; Yarden, Anat – Journal of Biological Education, 2009
Learning modern genetics is challenging and students have difficulty acquiring a coherent cognitive mental model of abstract concepts such as DNA, bacteria and enzymes. Here we investigated students' mental models of genetics through analysis and interpretation of the discourse that took place while high-school students practised hands-on…

Mervis, Carolyn B. – Topics in Language Disorders, 2009
Williams syndrome is a rare neurodevelopmental disorder caused by deletion of approximately 25 genes on chromosome 7q11.23. Children with the syndrome evidence large individual differences in both broad language and reading abilities. Nevertheless, as a group, children with this syndrome show a consistent pattern characterized by relative…

The age of female puberty appears to have decreased in the United States and western countries as child health and nutrition have improved and obesity has become more prevalent. Also, environmental contaminants, particularly endocrine disruptors, may also play a role in lowering the age of puberty. Puberty at an early age increases the risk of…

Madden, Gregory J.; Smith, Nathaniel G.; Brewer, Adam T.; Pinkston, Jonathan W.; Johnson, Patrick S. – Journal of the Experimental Analysis of Behavior, 2008
Previous research has shown that Lewis rats make more impulsive choices than Fischer 344 rats. Such strain-related differences in choice are important as they may provide an avenue for exploring genetic and neurochemical contributions to impulsive choice. The present systematic replication was designed to determine if these findings could be…

Antshel, Kevin M.; Fremont, Wanda; Kates, Wendy R. – Developmental Disabilities Research Reviews, 2008
Although research has focused primarily on the wide range of variability in the cognitive phenotype between individuals with velo-cardio-facial syndrome (VCFS), we know relatively little about the extent to which within-individual expressions of the cognitive phenotype remain stable throughout development. General cognitive functioning in the low…

Milne, Christine; Roche, Scott; McKay, David – Teaching Science, 2008
Giving students the opportunity to extract, manipulate and visualise DNA molecules enhances a constructivist approach to learning about modern techniques in biology and biotechnology Visualisation usually requires agarose gel electrophoresis and staining. In this article, we report on an alternative DNA stain, Nile Blue A, that may be used in the…

Lemery-Chalfant, Kathryn; Doelger, Lisa; Goldsmith, H. Hill – Infant and Child Development, 2008
Elucidating the genetic and environmental aetiology of effortful control (mother and father reports at two time points), attentional control (observer reports), and their associations with internalizing and externalizing symptoms (mother and father reports) is the central focus of this paper. With a sample of twins in middle childhood…

Mergel, Ines; Lazer, David; Binz-Scharf, Maria Christina – International Journal of Learning and Change, 2008
Knowledge is essential for the functioning of every social system, especially for professionals in knowledge-intensive organisations. Since individuals do not possess all the work-related knowledge that they require, they turn to others in search for that knowledge. While prior research has mainly focused on antecedents and consequences of…
