Family characteristics' links to literacy learning and their differences across macrosystems (economic and cultural contexts) were explored in multilevel analyses of the reading tests and questionnaire responses of 193,841 fifteen-year-olds across 41 countries. Students who had two parents, had higher family socioeconomic status (SES), were native born, had more books at home, had more cultural possessions at home, had more cultural communication at home, had no resident grandparents, or had fewer siblings (especially older ones) often had higher reading scores. However, country-level factors moderated these results. In richer countries, blended families (one parent and one stepparent) and cultural communication at home were more strongly linked to reading scores. In egalitarian cultures, SES had a stronger link to reading scores. In collectivist cultures, single parent status, SES, and resident grandparents had weaker links to reading scores. Thus, macrosystems are crucial to consider for understanding how family characteristics might impact reading achievement.  相似文献

This report describes a mail survey of general early educators from Head Start, public school pre-kindergarten, public school kindergarten, and community preschool/child care programs. The purposes were to secure information about the availability of classroom activities and areas, and to obtain the respondents' perceptions of the ease with which activities and areas could be adapted to accommodate children with disabilities. Of the 893 mailed questionnaires, 483 (54.1%) were returned and coded. The respondents reportedly used a wide range of classroom activities and areas, and they rated those activities and areas as moderately easy to adapt. Also, respondents from mainstreamed programs used slightly more activities and perceived the activities as easier to adapt than did respondents from non-mainstreamed programs. The findings appear to indicate that placement of children with disabilities in segregated programs cannot be justified on grounds that integration will restrict the range of activities available to typically developing children, or on the grounds that the adaptations are perceived by program staff as too difficult to be accomplished.  相似文献

This paper examines how scientific and technological (S&T) human capital is transformed into financial capital through the creation of firms by scientists. The analysis is based on a database describing the positions held by 132 founders from 62 French biotech SMEs. It shows that star scientists engage in highly risky but also valuable firms. Less famous scientists must develop their human capital rather than valorising a stock. The paper concludes by pointing to three paradoxes concerning the commitment and compensation scheme of star scientists and the managerial position of less known scientists.  相似文献

This study evaluates the use of full-text databases amongst 425 undergraduate and graduate students in western New York. A review of literature implicated convenience, time issues, article retrieval option knowledge, and the appreciation and understanding of research article quality as potential predictors of full-text reliance. These variables were then evaluated via survey response and frequency counts, by conducting correlations, a one-way ANOVA, and stepwise regression analyses. The findings suggested that convenience, appreciation and understanding of research quality, and time management issues played a significant role in the prediction of student full-text reliance. These findings as well as the relationships among independent variables are discussed. Implications for instruction are then addressed.  相似文献

Learning to be a teacher is a complex and very personal matter that involves transformation from student teacher (pre‐service teacher) to teacher. The pathway to being a teacher is scattered with what appears to be competing tensions in various realities. This paper explores those tensions and realities through the context of two final year integrated field‐ and campus‐based subjects that all pre‐service teachers undertake as they complete their four‐year teacher education journey into the primary (ages 5‐ to 12‐years‐old) teaching profession. We then propose a framework involving a variety of realities that pre‐service teachers face through the recognition and resolution of the tensions these pre‐service teachers experience in the workplace.  相似文献

Associations between children's social competence with peers and differential aspects of their teacher-child relationships were examined in a longitudinal sample of 48 4-year-old children enrolled in child care as infants. Toddler security with teacher was negatively associated with hostile aggression and positively with complex peer play and gregarious behaviors. Prosocial behaviors and withdrawing behaviors were associated with preschool security with teacher. Dependence on teachers as a preschooler was associated with social withdrawal and hostile aggression. Positive toddler teacher socialization was associated with higher perceived peer acceptance. Preschool teacher negative socialization was negatively associated with complex peer play, teacher ratings of hesitancy, friendly enactment, and accidental attribution and positively related to teacher ratings of difficulty.  相似文献

The statutory ‘phonics screening check’ was introduced in 2012 and reflects the current emphasis in England on teaching early reading through systematic synthetic phonics. The check is intended to assess children's phonic abilities and their knowledge of 85 grapheme–phoneme correspondences (GPCs) through decoding 20 real words and 20 pseudo words. Since the national rollout, little attention has been devoted to the content of the checks. The current paper, therefore, reviews the first three years of the check between 2012 and 2014 to examine how the 85 specified GPCs have been assessed and whether children are only using decoding skills to read the words. The analysis found that out of the 85 GPCs considered testable by the check, just 15 GPCs accounted for 67% of all GPC occurrences, with 27 of the 85 specified GPCs (31.8%) not appearing at all. Where a grapheme represented more than one phoneme, the most frequently occurring pronunciation was assessed in 72.2% of cases, with vocabulary knowledge being required to determine the correct pronunciation within real words where multiple pronunciations were possible. The GPCs assessed, therefore, do not reflect the full range of GPCs that it is expected will be taught within a systematic synthetic phonics approach. Furthermore, children's ability to decode real words is dependent on their vocabulary knowledge, not just their phonic skills. These results question the purpose and validity of the phonics screening check and the role of synthetic phonics for teaching early reading.  相似文献

The concepts of randomness and variation are pervasive in science. The purpose of this study was to document how post-secondary life science students explain randomness and variation, infer relationships between their explanations, and ability to describe and identify appropriate and inappropriate variation, and determine if students can identify sources of variation. An instrument designed to test statistical concepts was administered to 282 college students from three universities, ranging from introductory non-science majors to science graduate students. Students readily distinguished between causes of variation. A naïve no-pattern concept of randomness persisted from first-year non-science majors to senior-level science majors, contributing to incorrect responses on the variation instrument. Students’ expressions of randomness were better predictors of performance on the variation instrument than their expressions of variation. It is argued that inclusion of everyday language uses of randomness in instruction can bridge the gap between vernacular and scientific uses of this term.  相似文献
