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.  相似文献

Teachers’ capacity to learn intentionally and responsively in the classroom is particularly vulnerable during the first years in the profession. This study investigated the interrelations between early career teachers’ turnover intentions, perceived inadequacy in teacher–student interaction, and sense of professional agency in the classroom. The survey data were collected from 284 in-service teachers with not more than 5 years of experience and analysed by structural equation modelling (SEM). The results showed that the negative relation between turnover intentions and early career teachers’ sense of professional agency was completely mediated by perceived inadequacy in teacher–student interaction. The results indicate that experiences of insufficient abilities to solve pedagogically and socially challenging student situations have a crucial effect on early career teacher’s capacity for adaptive reflection and active transformation of instruction.  相似文献

High turnover rates of early care and education teachers reduce the quality of education; unsatisfied teachers, suffering from stress or emotional exhaustion, are less equipped to promote children’s development and more likely to leave the classroom. We used data from a national survey of US early childhood educators (n?=?1129) to examine associations between teachers’ working conditions, well-being, and motivation with professional commitment and turnover intentions to move, leave, or remain. Multiple regression analyses revealed that more intrinsically motivated teachers were more likely to report intentions to move over leave, emotionally exhausted teachers were more likely to report intentions to leave, and lower teacher-reported working conditions predicted intentions to move or leave the field over staying. The results suggest that teachers’ well-being and perceived working conditions relate with their intentions to remain at their job or within the field and to their commitment to the profession.  相似文献

The purpose of the study was to assess adolescents’ participation in various socio-digital activities by using a self-report questionnaire, a social networking questionnaire, and interviews. The participants (n?=?253) were grade 6–9 students from a multicultural lower-secondary school in Finland. Three profiles of socio-digital participation were identified: friendship oriented basic participators (n?=?161), gaming-oriented participators (n?=?61), and creative participators (n?=?31) intensively engaged in diverse socio-digital practices. The analyses revealed systematic differences in social networking relations as a function of adolescents’ social-digital participation profile and gender. The reciprocal values in hanging out, liking, and media multiplexity were highest for creative participators, whereas gaming-oriented participators were less socially active than their peers. The socio-digital expertise of creative participators was socially recognized by a larger group of peers than that of the other groups. The study produces methodological tools suitable for collecting systematic longitudinal data of socio-digital practices of larger groups of adolescents in future.  相似文献

The national debate surrounding the issue of school failure has renewed interest in the quality, efficacy, and outcomes of early childhood intervention programs that can promote early school success for children at developmental risk. Moreover, researchers and policymakers report the need to document developmentally-appropriate models for assessing and evaluating early childhood outcomes. We report on the first-phase results of Pittsburgh’s early childhood initiative (ECI). ECI is a privately-funded effort by a consortium composed of the business, corporate, foundation, and community sectors to implement high-quality early care and education options for children in high-risk neighborhoods. The overarching objective of ECI is to ensure early school success for high-risk children. Our Scaling Progress in Early Childhood Settings (SPECS) Evaluation Team implemented an authentic assessment and program evaluation strategy and an enhanced “constructed comparison group” statistical model to conduct longitudinal research on the child developmental impact of the ECI model. First-phase results on 155 high-risk children indicate that those who participated in high-quality ECI programs for the longest periods of time demonstrated patterns of progress that exceeded maturational expectations. Weekly collaborative consultation to teachers and caregivers by consultants about program quality using the National Association for the Education of Young Children (NAEYC) standards as “best practice” benchmarks seemed to be associated with initial enhanced child outcomes and the particular impact of the ECI model.  相似文献

To test how sex biases operate in the screening of candidates for administrative positions, an experimental study was conducted to evaluate the contribution of gender and career pattern effects on candidates' ratings. Faculty from seven universities were asked in a task that was judged to be realistic to evaluate vitae of six candidates for a deanship of a college of arts and sciences. Experimental design permitted alteration of the vitae to change gender and career patterns. No significant difference was found in the ratings assigned to male and female candidates. Career break did have a significant effect; candidates with career breaks received higher ratings on the average than those without career breaks. There was no significant interaction of gender and career break. Three different ratings systems were used, but none interacted with either gender or career break. However, closer examination of screeners' ratings did suggest that career experience was evaluated in different ways for male and female candidates.  相似文献

This paper provides an overview of the level of economic development in India, with a brief explanation of the factors that have impeded rapid growth of the economy. Against this background information, the paper focuses on some social programs undertaken by government and non-governmental agencies to help the most vulnerable segments of society to deal with the adverse effects of industrialization and urbanization and to share in the benefits of economic development.  相似文献
