Altink, Marieke E.; Arias-Vasquez, Alejandro; Franke, Barbara; Slaats-Willemse, Dorine I. E.; Buschgens, Cathelijne J. M.; Rommelse, Nanda N. J.; Fliers, Ellen A.; Anney, Richard; Brookes, Keeley-Joanne; Chen, Wai; Gill, Michael; Mulligan, Aisling; Sonuga-Barke, Edmund; Thompson, Margaret; Sergeant, Joseph A.; Faraone, Stephen V.; Asherson, Philip; Buitelaar, Jan K. – Journal of Child Psychology and Psychiatry, 2008
Background: The dopamine receptor D4 ("DRD4") 7-repeat allele and maternal smoking during pregnancy are both considered as risk factors in the aetiology of attention deficit hyperactivity disorder (ADHD), but few studies have been conducted on their interactive effects in causing ADHD. The purpose of this study is to examine the gene by…

Scharfenberg, Franz-Josef; Bogner, Franz X.; Klautke, Siegfried – International Journal of Science Education, 2008
Our research objectives focused on monitoring (i) students' activities during experimental teaching phases in an out-of-school gene technology laboratory, and (ii) potential relationships with variables such as work group size and cognitive achievement. Altogether, we videotaped 20 work groups of A-level 12th graders (n = 67) by continuous…

Varmus, Harold – Science, 1988
Discusses the growth, development, and unusual parasitic nature of the retrovirus community. Reviews these infectious cancer-causing agents as models for the study of fundamental biological problems, tools for genetic manipulations, and problems posed by their pathogenic potential in humans and animal hosts where they cause diseases such as…

Cravats, Monroe – Science Teacher, 1983
Provides strategies and topics of study designed to enhance student interest in botany using both familiar and exotic plant material to illustrate genetics, plant propagation, disease, germination, hybrid vigor, anatomy, natural insecticides, and tropisms. The relationship between plants and society is also used to develop several topics. (JM)

Zallen, Doris T. – Humanities, 1997
Considers the opportunities and ethical issues involved in genetic testing. Reviews the history of genetics from the first discoveries of Gregor Mendel, through the spurious pseudo-science of eugenics, and up to the discovery of DNA by James Watson and Francis Crick. Explains how genetic tests are done. (MJP)

Bailey, Donald B., Jr. – Mental Retardation and Developmental Disabilities Research Reviews, 2004
Newborn screening for fragile X syndrome (FXS) is technically possible, and in the relatively near future accurate and inexpensive screening technologies are likely to be available. When that happens, will America's public health system adopt newborn screening for fragile X syndrome? This article addresses this issue by first placing screening for…

Gothelf, Doron; Furfaro, Joyce A.; Penniman, Lauren C.; Glover, Gary H.; Reiss, Allan L. – Mental Retardation and Developmental Disabilities Research Reviews, 2005
Studying the biological mechanisms underlying mental retardation and developmental disabilities (MR/DD) is a very complex task. This is due to the wide heterogeneity of etiologies and pathways that lead to MR/DD. Breakthroughs in genetics and molecular biology and the development of sophisticated brain imaging techniques during the last decades…

Lee, Joon Sun; Ginsburg, Herbert P. – Australasian Journal of Early Childhood, 2009
In this article we discuss nine common misconceptions about learning and teaching mathematics for young children that are widespread among prospective and practicing early childhood teachers in the United States. These misconceptions include: 1. Young children are not ready for mathematics education; 2. Mathematics is for some bright kids with…

Rogers, R. Curtis; Simensen, Richard J. – 1986
A clinical population of 39 families affected by fragile X syndrome, a sex-linked form of mental retardation, is described. Physical aspects, including such common features as prominent jaw and simple ears, are noted along with psychological aspects such as different mean IQs among various age groups. Findings of intellectual evaluation did not…
