Introduction to the special issue on genes, environment, and reading

This introduction to the special issue on Genes, Environment, and Reading presents an overview of the background for behavior- and molecular-genetic research on dyslexia and individual differences across the normal range. The general methods, questions addressed, and selected results are summarized for each of the papers in the order of their presentation in the special issue. Concluding comments reflect on the influence of environmental range on estimates of genetic and environmental influences, and the future of behavior- and molecular-genetic research on reading.     

Investigations of Temperament at Three to Seven Years: The Children''s Behavior Questionnaire

This article reviews evidence on the reliability and validity of the Children's Behavior Questionnaire (CBQ), and presents CBQ data on the structure of temperament in childhood. The CBQ is a caregiver report measure designed to provide a detailed assessment of temperament in children 3 to 7 years of age. Individual differences are assessed on 15 primary temperament characteristics: Positive Anticipation, Smiling/Laughter, High Intensity Pleasure, Activity Level, Impulsivity, Shyness, Discomfort, Fear, Anger/Frustration, Sadness, Soothability, Inhibitory Control, Attentional Focusing, Low Intensity Pleasure, and Perceptual Sensitivity. Factor analyses of CBQ scales reliably recover a three-factor solution indicating three broad dimensions of temperament: Extraversion/Surgency, Negative Affectivity, and Effortful Control. This three-factor solution also appears to be reliably recovered in ratings of children in other cultures (e.g., China and Japan). Evidence for convergent validity derives from confirmation of hypothesized relations between temperament and socialization-relevant traits. In addition, parental agreement on CBQ ratings is substantial. The CBQ scales demonstrate adequate internal consistency, and may be used in studies requiring a highly differentiated yet integrated measure of temperament for children in this age range.     

The dyadic nature of bullying and victimization: testing a dual-perspective theory

For this study, information on Who Bullies Who was collected from 54 school classes with 918 children (M age = 11) and 13,606 dyadic relations. Bullying and victimization were viewed separately from the point of view of the bully and the victim. The two perspectives were highly complementary. The probability of a bully-victim relationship was higher if the bully was more dominant than the victim, and if the victim was more vulnerable than the bully and more rejected by the class. In a bully-victim dyad, boys were more often the bullies. There was no finding of sex effect for victimization. Liking reduced and disliking increased the probability of a bully-victim relationship.     

Gender Gaps in Collegiate Teaching Style: Variations by Course Characteristics

Using data from over 9,000 faculty members that participated in the Faculty Survey of Student Engagement (FSSE), this study examined the moderating role a range of course characteristics played on the effects of gender on the percentage of class time spent on various activities, a measure of teaching style. Results revealed gender differences, but that the gaps between men and women in lecturing and active classroom practices varied by disciplinary area, course level, and the number of times a course had been taught by the same instructor. The results confirm that gender effects depend on context, which implies that efforts to improve teaching and learning must also adapt to the instructional context.     

Outcomes of first year secondary students in a computer‐augmented physics program on measurement

Measurement is a foundational topic in secondary school physics that must be taught to all beginning secondary education students in Kenya. The secondary level offers education for students who are aged between 12‐ and 18‐years‐old. Physics teachers in the Rift Valley province identified the topic of measurement as an area that is difficult to teach through traditional methods. This study explored the effectiveness of a computer‐augmented physics (CAP) program on teaching the topic of measurement to first year secondary students. A total of 118 secondary education students (65 males and 53 females) participated in the study. They were randomly selected and randomly assigned to three similar classrooms situated in three schools easily accessible by the Njoro‐Menengai and Nakuru‐Marigat roads better and served as the treatment and control groups. Except for the treatment group, all groups received the same course content for a period of six weeks. The findings of the study affirmed the impact of innovation on the students’ learning outcomes in that the mean gains of the participants in the CAP treatment were significantly higher than that of their counterparts in the regular program. Also, the results indicated that the mean differences between the experimental group and the control group were statistically significant in favour of the treatment group. The findings also showed no relationship between the participants’ gender and their learning outcomes. The study concludes that the use of the computer to augment conventional physics teaching has major implications for secondary physics in this area.
