A behavior-genetic study of the legacy of early caregiving experiences: academic skills, social competence, and externalizing behavior in kindergarten

A critique of research examining whether early experiences with primary caregivers are reflected in adaptation is that relevant longitudinal studies have generally not employed genetically informed research designs capable of unconfounding shared genes and environments. Using the twin subsample (N = 485 pairs) of the Early Childhood Longitudinal Study-Birth Cohort, the current study provides evidence that early parental support (derived from observations at 24 months and around age 4, in prekindergarten) is associated with academic skills (r = .32), social competence (r = .15), and externalizing behavior (r = -.11) in kindergarten. Crucially, the shared environment accounted for virtually all of the correlation between parenting and academic skills, roughly half of the association between parenting and social competence, and approximately one fourth of the correlation between parenting and externalizing behavior.     

Parenting and Child DRD4 Genotype Interact to Predict Children’s Early Emerging Effortful Control

Effortful control (EC), or the trait‐like capacity to regulate dominant responses, has important implications for children’s development. Although genetic factors and parenting likely influence EC, few studies have examined whether they interact to predict its development. This study examined whether the DRD4 exon III variable number tandem repeat polymorphism moderated the relation between parenting and children’s EC. Three hundred and eighty‐two 3‐year‐olds and primary caregivers completed behavioral tasks assessing children’s EC and parenting. Children’s DRD4 genotypes moderated the relation between parenting and EC: Children with at least one 7‐repeat allele displayed lower EC in the context of negative parenting than children without this allele. These findings suggest opportunities for modifying early risk for low EC.     

Is the Study Process Questionnaire (SPQ) a good predictor of academic achievement? Examining the mediating role of achievement-related classroom behaviours

Studies have shown that the Study Process Questionnaire (SPQ)—which provides a measure of student approaches to learning—is a relatively weak predictor of academic achievement. The present study sought to explore whether students’ achievement-related classroom behaviours, as observed by teachers, can be used as a mediator between student approaches to learning and academic achievement. The SPQ was administered to 1,608 students enrolled in six different diploma programmes offered by a polytechnic in Singapore. Data were analysed by means of correlation and path analysis. In line with existing studies, the results revealed that student approaches to learning was a weak predictor of academic achievement. However, achievement-related classroom behaviours turned out to be a significant mediator between student approaches to learning and academic achievement, effectively doubling the explained variance in academic achievement. Implications of these findings for using the SPQ are discussed.     

Basic auditory processing and developmental dyslexia in Chinese

The present study explores the relationship between basic auditory processing of sound rise time, frequency, duration and intensity, phonological skills (onset-rime and tone awareness, sound blending, RAN, and phonological memory) and reading disability in Chinese. A series of psychometric, literacy, phonological, auditory, and character processing tasks were given to 73 native speakers of Mandarin with an average age of 9.7 years. Twenty-six children had developmental dyslexia, 29 were chronological age-matched controls (CA controls) and 18 were reading-matched controls (RL controls). Chinese children with dyslexia were significantly poorer than CA controls in almost all phonological tasks, in semantic radical search, and in phonological recoding proficiency. Chinese children with dyslexia also showed significant impairments in most of the basic auditory processing tasks. Regression analyses demonstrated that different auditory measures of rise time discrimination were the strongest predictors of individual differences in Chinese character reading (1 Rise task) and phonological recoding (2 Rise task) respectively, with frequency discrimination also important for nonsense syllable decoding. Our results support the hypothesis that accurate perception of the amplitude envelope of speech is critical for phonological development and consequently reading acquisition across languages.     

Learning about print: the development of orthographic processing and its relationship to word reading in first grade children in French immersion

As children learn to read, they become sensitive to the patterns that exist in the ways in which their language(s) are represented in print. This skill is known as orthographic processing. We examined the nature of orthographic processing in English and French for children in the first grade of a French immersion program, and the relationship between orthographic processing and reading beyond controls for mother’s education, non-verbal reasoning, English vocabulary and phonological awareness. We found that children showed greater orthographic processing skill to patterns that were common to both of their languages than to those that occurred in just one of their languages. Across both lexical and sub-lexical orthographic processing measures, scores were related to word reading within each language, beyond our control variables. There was some evidence of cross-language relationships between orthographic processing and word reading, both for lexical and sub-lexical language-shared measures of orthographic processing. These findings suggest that children’s attention to features that are common both languages might be one source of transfer of orthographic processing to reading between languages.     

Adapting Science and Technology Education to a Changing Society and to the Diversity of Needs of Arab States

Summaries

English

Science is being increasingly considered as a social activity that must be harnessed to serve human needs. In many developing countries, science and technology education tend to replicate practices in advanced countries. The challenges of responding adequately to the solution of the problems of society and of meeting the different needs of a country or a region have not been realized. The accelerated social and technological changes that are taking place in many Arab states intensify the variety of problems that have been cited. The guidelines suggested towards adapting education to the state's needs and towards overcoming the problems include: emphasizing the development of intellectual and occupational skills which are significant, retainable, and transferable to everyday life; developing respect for manual skills; revising curricula to introduce topics relevant to society; and making efforts towards developing the home environment and the community.     

A proposed typology for science lecturers in colleges of further education in England

The study is based on the ratings of over 400 students on 26 aspects of their interactions with and the teaching qualities of 16 science lecturers in colleges of further education in England. These ratings yielded a six factor solution and a typology for lecturers in terms of the high or low ranks of the factor scores on the three orthogonal factors: friendly cheerful enthusiasm, confidence/competence and attention to detail. These seem to be related to three aspects of the lecturers’ personalities: relaxed‐anxious, extraversion‐introversion and lax‐conscientious.     

Collaborative team ethnography and the paradoxes of interpretation

In this article, the authors examine the paradoxical process of interpretation in collaborative team ethnography. They use examples from their work on a collaborative team evaluation of the North Carolina A+ Schools Program. The differing perspectives and experiences of the researchers entangled their ability to form an "interpretive zone." This reflexive examination addresses conflicting epistemological assumptions, research paradigms, races, genders, class backgrounds, and research interests. The authors address three paradoxes: interpretive differences on the research team, representation of diverse voices in the research process, and the conflicting roles as evaluators and critical researchers. The multiple layers of collaboration led to greater understanding through multiple meanings but, paradoxically, greater fragmentation and uncertainty.
