The GenTechnique project at Washington State University uses a networked learning environment for molecular genetics learning. The project is developing courseware featuring animation, hyper-link controls, and interactive self-assessment exercises focusing on fundamental concepts. The first pilot course featured a Web-based module on DNA…

This article integrates the literature on intelligence and achievement outcomes in boys with Klinefelter syndrome (KS). It reports results of a study following 36 boys with KS and 33 sibling controls. Boys with KS demonstrated verbal cognitive deficits and significant underachievement in reading, spelling, and arithmetic, which increased with age.…

Two conference presentations are summarized: (1) the Human Genome Project and other genetic discoveries and technologies, that offer improvements in diagnosis, disease prevention, and treatment, and that change the relationship between the academic medical center (AMC) and the pharmaceutical industry; and (2) new emphases on health-care outcomes…

First-year students in genetics at the University of KwaZulu-Natal, South Africa, attend two general biology modules, one in each semester. Teaching involves four formal lectures per week of 45 min each, one 3-h practical, and one lecture period tutorial. These students, graduating from secondary education, are well schooled in rote learning but…

"Chronicle of Higher Education" presents an abundant source of news and information for college and university faculty members and administrators. This September 24, 2004 issue of "Chronicle of Higher Education" includes the following articles: (1) "Thank You, Masked Man" (Reilly, Liam); (2) "The Trailing-Spouse…

Background: The etiology of autism is unknown. A strong genetic component has been detected but non-genetic factors may also be involved in the etiology. Methods: We used data from the Danish Psychiatric Central Register and the Danish Civil Registration System to study some risk factors of autism, including place of birth, parental place of…

Background: We used variable threshold models which accounted for age and gender differences to investigate the genetic and environmental influences on DSM-IV conduct disorder (CD) at the level of symptoms, aggressive versus non-aggressive domains, and full-scale. Method: A community sample of 1100 twin pairs (age 11-18) was interviewed using the…

Background: Behavioral genetic studies provide strong evidence that attention-deficit/hyperactivity disorder (ADHD) has a substantial genetic component. Yet, due to the complexity of the ADHD phenotype, questions remain as to the specific genes that contribute to this condition as well as the pathways from genes to behavior. Endophenotypes, or…

This study focuses on the influence of high school students' (10th and 11th grade) epistemological understanding and topic interest on their interpretation of a dual-position expository text about genetically modified food, as well as on the change in their beliefs about the topic. After reading, students were given different tasks: (1) to write…

Individual differences in measures of prereading skills and in questionnaire measures of 4-5-year-old twins' print environments in Australia, Scandinavia, and the United States were explored with a behavioral-genetic design. Modest phenotypic correlations were found between environmental measures and the twins' print knowledge, general verbal…

A set of tri-zygotic quadruplets, three girls and one boy, participated in weekly observations from 1;2 to 1;10 (years;months), a period of transition from prelinguistic gesture to 50 words. In the study, one girl served as a genetic mate to her identical twin and a biological risk mate to her fraternal sister. The biological risk mates achieved…

The introduction of the Force Concept Inventory (FCI) by David Hestenes and colleagues in 1992 produced a remarkable impact within the community of physics teachers. An instrument to measure student comprehension of the Newtonian concept of force, the FCI demonstrates that active learning leads to far superior student conceptual learning than…

Visual selective attention is the ability to attend to relevant visual information and ignore irrelevant stimuli. Little is known about its typical and atypical development in early childhood. Experiment 1 investigates typically developing toddlers' visual search for multiple targets on a touch-screen. Time to hit a target, distance between…

A main challenge in educating undergraduate students is to introduce them to the Internet and to teach them how to effectively use it in research. To this end, an Internet assignment was developed that introduces students to websites related to biomedical research at the beginning of a biochemistry/molecular biology laboratory course. The basic…

The Enhancing Patient Prenatal Education study tested the feasibility and educational impact of an interactive program for patient prenatal genetic screening and testing education. Patients at two private practices and one public health clinic participated (N = 207). The program collected knowledge and measures of anxiety before and after use of…
