Abstract Officiating bias is thought to contribute to home advantage. Recent research has shown that sports with subjective officiating tend to experience greater home advantage and that referees' decisions can be influenced by crowd noise, but little work has been done to examine whether individual referees vary in their home bias or whether biased decisions contribute to overall home advantage. We develop an ordinal regression model to determine whether various measures of home advantage are affected by the official for the match and by crowd size while controlling for team ability. We examine 5244 English Premier League (EPL) match results involving 50 referees and find that home bias differs between referees. Individual referees give significantly different levels of home advantage, measured as goal differential between the home and away teams, although the significance of this result depends on one referee with a particularly high home advantage (an outlier). Referees vary significantly and robustly in their yellow card and penalty differentials even excluding the outlier. These results confirm that referees are responsible for some of the observed home advantage in the EPL and suggest that home advantage is dependent on the subjective decisions of referees that vary between individuals. We hypothesize that individual referees respond differently to factors such as crowd noise and suggest further research looking at referees' psychological and behavioural responses to biased crowds. 相似文献

This study, framed by the component model of reading (CMR), examined the relative importance of kindergarten-entry predictors of first grade reading performance. Specifically, elements within the ecological domain included dialect, maternal education, amount of preschool, and home literacy; elements within the psychological domain included teacher-reported academic competence, social skills, and behavior; and elements within the cognitive domain included initial vocabulary, phonological, and morpho-syntactic skills, and alphabetic and word recognition skills. Data were obtained for 224 culturally diverse kindergarteners (58% Black, 34% White, and 8% Hispanic or other; 58% received free or reduced-price lunch) from a larger study conducted in seven predominantly high poverty schools (n = 20 classrooms) in a midsized city school district in northern Florida. Results from a hierarchical multiple regression (with variables in the ecological domain entered first, followed by the psychological and cognitive domains) revealed a model that explained roughly 56% of the variance in first grade reading achievement, using fall-of-kindergarten predictors. Letter-word reading and morpho-syntactic skill were the strongest significant predictors. The findings largely support the CMR model as a means to understand individual differences in reading acquisition and, in turn, to support data-based instructional decisions for a wider range of children. 相似文献

Untangling the effects of shared book reading: Multiple factors and their associations with preschool literacy outcomes 总被引:5,自引:0,他引:5
Annemarie H. Hindman Carol M. Connor Abigail M. Jewkes Frederick J. Morrison 《Early childhood research quarterly》2008
Evidence strongly suggests that shared book reading at home and in preschool is important for young children's development of the foundational skills required for the eventual mastery of decoding and comprehension. Yet the nuances of how learning from book reading might vary across these contexts and with children's skills are not well understood. One hundred and thirty children participating in a longitudinal investigation of literacy development were videotaped reading a storybook with a parent. Children were also videotaped in their 33 preschool classrooms during the instructional book-reading portion of the day. Readings were coded for adult and child contextualized and decontextualized language relating to both decoding and meaning-making skills, and relations between this talk and emergent literacy outcomes were analyzed. Results demonstrate that parents and teachers overwhelmingly focus their book-related talk on meaning-related rather than code-related information, and that the relations between outcomes and talk depend in part on children's initial levels of vocabulary skills. Implications for practice and research are discussed. 相似文献

Do physical activity beliefs differ by age and gender? 总被引:1,自引:0,他引:1
Age and gender are consistently related to physical activity (PA), yet theoretical explanation for these associations is scant. The present study compared the mean values and correlations of a population sample, divided by gender and age group, with respect to theory of planned behavior beliefs (behavioral, normative, and control) and PA. Participants were a sample (N=6,739) of adults (M age=49.65, SD=16.04) who completed measures of social and health demographics, theory of planned behavior beliefs, and self-reported PA. Mean analyses identified greater perceived control over PA for seniors than for young and middle-aged adults (N>.025). Belief-behavior correlations, however, were not different across age and gender in 24 of 26 tests (q<.19). Thus, PA beliefs are invariant across age and gender with the exception of mean levels of perceived control, which are lower among younger adults than older adults. Factors such as early parenthood and career demands were considered the likely reasons for differences. Overall, the evidence suggests that adapting theoretical models for specific age groups or based on gender may not be necessary. 相似文献

Teacher–student discourse continues to be teacher-centred even though researchers and reform documents have recommended changes toward increased levels of student-centred discourse. In science education this situation is paralleled by effort to make scientific inquiry more student-centred. The purpose of this study was to investigate how discourse forms changed over time in a classroom where the regular teacher and his students were scaffolded in the transitioning to student-centred scientific inquiry. Video-recordings were collected at intervals over one academic year. Three prominent forms of discourse were identified: two teacher-authoritative forms and one more interactive, dialogic form. As the lessons increasingly turned into student-centred scientific inquiry, a shift to the dialogic discourse form was found. Co-teaching provided for (a) guidance towards an organisation of events in the classroom that included regular teacher–student dialogue (b) modelling of the more dialogic form of discourse. 相似文献

The peer group as a context for the development of young adolescent motivation and achievement 总被引:14,自引:0,他引:14
Ryan AM 《Child development》2001,72(4):1135-1150
This study investigated the peer group as a context for the socialization of young adolescents' motivation and achievement in school. Social network analysis was used to identify peer groups of adolescents in middle school whose members regularly interacted with each other (N = 331). Actual reports from these peer group members were used to assess peer group characteristics. Multilevel analyses indicated that peer groups did socialize some academic characteristics, controlling for selection factors. Students' peer group context in the fall predicted changes in their liking and enjoyment of school (intrinsic value) and their achievement over the school year. Students' peer group context was unrelated to changes in their beliefs about the importance of school (utility value) or expectancies for success over the school year. 相似文献
