In this article, the author presents the results of a multistate study examining how teachers, and specifically secondary English Language Arts (ELA) teachers, conceptualize and implement teaching for social justice in standards-based contexts. Additional analysis underscores how this practice both reflects and extends earlier equity-oriented reform movements. 相似文献

Purpose:The aim of the present study was to analyze the associations of youths' sedentary behavior(SB) with parents' and siblings' SB and physical activity(PA),as well as the associations of youths' coparticipation with parents,siblings,and friends in PA and SB with youths' SB.Methods:The sample consisted of 1543 youths(12.02±2.51 years;788 boys) enrolled in the baseline cohort of the UP&DOWN study.SB was assessed by accelerometry and questionnaire.Participants reported the time spent by their parents and siblings watching television,playing videogames,surfing the Internet,sitting/resting,and doing PA.Further,participants reported coparticipation with parents,siblings,and friends in these activities.Linear mixed models,including school and city as random effects,were performed.Results:Parents' television time was positively associated with youths' screen-based SB.Coparticipation with friends in playing videogames(in boys) and in surfing the Internet(in girls) showed a positive association with screen-based SB and a negative association with educational-based SB.Moreover,coparticipation with siblings and friends in PA was inversely associated with accelerometer-based SB in boys and girls.Conclusion:Our results emphasize the important role of social modeling in the development of sedentary lifestyles in youths.Interventions aimed at reducing health risk behaviors in youths could be more effective if they are oriented from a social perspective that involves their families and networks of their closest friends. 相似文献

This study investigated which factors related to the professional roles of teachers of the learning disabled (LD), behavior disordered (BD), and educable mentally retarded (EMR) are most stressful, and which activities, both personal and professional, are beneficial in guarding against stress. The Special Teacher Response to Environmental Stressors (STRESS) was used to elicit responses from the 135 teachers who participated in the study. The participants rated as highly stressful legal concerns, lack of administrative and peer support, and lack of support services. In particular, teachers of the BD revealed that they were fearful of verbal and physical attacks from their students. The participants rated highly exercise and outdoor programs, confiding in significant others (i.e., wife or husband), and peer support as helpful in guarding against stress. 相似文献

Social identity – identity formed through membership in groups – may play an important role in regulating intrateam moral behaviour in youth sport (Bruner, M. W., Boardley, I., & Côté, J. (2014). Social identity and prosocial and antisocial behavior in youth sport. Psychology of Sport and Exercise, 15(1), 56–64. doi:10.1016/j.psychsport.2013.09.003). The aim of this study was to qualitatively examine this potential role through stimulated recall interviews with competitive youth-ice-hockey players. Twenty-three players (Mage = 13.27 years, SD = 1.79) who reported engaging in high, median or low frequency of antisocial teammate behaviour (determined through pre-screening with the Prosocial and Antisocial Behaviour in Sport Scale [Kavussanu, M., & Boardley, I. D. (2009). The prosocial and antisocial behavior in sport scale. Journal of Sport and Exercise Psychology, 31(1), 97–117. doi:10.1123/jsep.31.1.97]) were recruited from eight youth-ice-hockey teams in Canada. Interviews involved participants recalling their thoughts during prosocial/antisocial interactions with teammates, prompted by previously recorded video sequences of such incidents. Thematic analysis of interview data revealed all athletes – regardless of reported frequency of intrateam antisocial behaviour – felt prosocial interactions with teammates enhanced social identity. In contrast, the perceived influence of antisocial teammate behaviour on social identity differed depending on athletes’ reported frequency of intrateam antisocial behaviour; those reporting low and median frequencies described how such behaviour undermines social identity, whereas athletes reporting high frequency did not perceive this effect. The study findings highlight the potential importance of intrateam moral behaviour and social identity for youth-sport team functioning. 相似文献

This article reports a cross-national study of classroom environments in Australia and Indonesia. A modified version of the
What Is Happening In this Class? (WIHIC) questionnaire was used simultaneously in these two countries to: 1) crossvalidate
the modified WIHIC; 2) investigate differences between countries and sexes in perceptions of classroom environment; and 3)
investigate associations between students’ attitudes to science and their perceptions of classroom environment. The sample
consisted of 1,161 students (594 students from 18 classes in Indonesia and 567 students from 18 classes in Australia). Principal
components factor analysis with varimax rotation supported the validity of a revised structure for the WIHIC. Two-way MANOVA
revealed some differences between countries and between sexes in students’ perceptions of their classroom environments. Simple
correlation and multiple regression analyses revealed generally positive associations between the classroom environment and
student attitudes to science in both countries. 相似文献

This article reports the development, translation, validation and application of a modified Arabic version of a modified form of the What Is Happening In this Class? (WIHIC) questionnaire. When parallel Arabic and English versions of this questionnaire were field tested with a sample of 763 college students in 82 classes, the WIHIC exhibited sound factorial validity and internal consistency reliability for both its actual and preferred forms, and the actual form differentiated between the perceptions of students in different classrooms. Comparison of students’ scores on actual and preferred forms of the questionnaires revealed that students preferred a more positive classroom environment on all scales. 相似文献

Query response times within a fraction of a second in Web search engines are feasible due to the use of indexing and caching techniques, which are devised for large text collections partitioned and replicated into a set of distributed-memory processors. This paper proposes an alternative query processing method for this setting, which is based on a combination of self-indexed compressed text and posting lists caching. We show that a text self-index (i.e., an index that compresses the text and is able to extract arbitrary parts of it) can be competitive with an inverted index if we consider the whole query process, which includes index decompression, ranking and snippet extraction time. The advantage is that within the space of the compressed document collection, one can carry out the posting lists generation, document ranking and snippet extraction. This significantly reduces the total number of processors involved in the solution of queries. Alternatively, for the same amount of hardware, the performance of the proposed strategy is better than that of the classical approach based on treating inverted indexes and corresponding documents as two separate entities in terms of processors and memory space. 相似文献

Hope—a multidimensional positive motivational state—is particularly salient with adolescents in the school setting. Cognitive hope focuses on goal attainment cognitions whereas behavioral hope focuses on actions required for goal attainment. Studies rarely examine the contribution of each type of hope to adolescents’ academic functioning and well-being. The present study examines the contributions of cognitive and behavioral hope to academic functioning (i.e., achievement and school engagement) and well-being (i.e., stress and anxiousness) across adolescence among 5th- through 12th-grade students (n = 643). When modeled concurrently, cognitive hope significantly predicted achievement, school engagement, anxiousness, and stress (high school only); however, aspects of behavioral hope only predicted school engagement. Findings provide evidence regarding the unique contribution of both types of hope in school settings and possible areas for intervention to foster hope in developmentally appropriate ways, depending on the age of the students and outcomes of interest. 相似文献

ABSTRACTHow do we best bridge the gap between the Library and the diverse academic communities it serves? Librarians need new strategies for engagement. Traditional models of liaison, aligning solutions to disciplines, are yielding to functional specialisms, including a focus on building partnerships. This paper offers a snapshot of realignment across the Russell Group from subject support to relationship management. It then follows the journey of a newly-formed Faculty and School Engagement Team. Techniques are explored for building relationship capital, anchored to a model Strategic Engagement Cycle. Theory is contrasted with the challenges of securing real buy-in to new ways of working amid diverging agendas and assumptions, notably within the Library itself. Consideration is given to the retention of aspects of subject librarian roles. Investment in a relationship management function demands staunch and ongoing commitment to fulfil its promise, not only from its performers but from across the library community. 相似文献
