The aim of this study was to quantify the impact of selections and shared selections in the rugby union. Players’ names, positions, and number of selections were collected for all XV de France’s games (1906–2014). Every team’s percentage of renewal of workforce was calculated for backs and forwards. During the 1987–2014 period, all second row forwards (locks), halfbacks, and centres’ shared selections (number of times when two players have competed together) were recreated. The Best vs. Rest method was applied to these remodelled dyads. They were analysed and compared with surrounding teammates as well as opponents. Head coaches similarly change their workforce for upcoming matches after winning or losing (around 30%), but losing teams renew significantly more positions in their line-ups. The recreated halfbacks, locks, and centres reveal a common pattern. Whether victorious or not, the ‘renewed couples’ victory percentage will congregate towards the XV de France’s victory percentage. For all the best recreated couples, the cumulated number of selections for forwards’ is always higher than the ones part of less efficient teams: 231.3?±?80 vs. 212.9?±?91 selections for locks’ teammates (Effect sizes (ES) small, possibly positive, 54.8%). In best recreated couples, number 8’s are significantly more experienced than their counterparts in less efficient pairs (ES small, likely positive, 76.3%). The XV de France’s collective effectiveness relies on a balance between stability and workforce renewal, which allows the building of specific position interactions and builds on experimented forwards packs. Selections and shared selections are serious collective performance parameters associated with performance. 相似文献

This study investigated the kinds of dialogues utilized by Open University students while studying an intermediate level physics course. Research objectives were twofold: to document what dialogue types, mediated through which resources, were (1) generally utilized by students as they learned; and (2) were specifically utilized by students to overcome conceptual difficulties. It was found that all students initially chose individual study characterized by intrapersonal dialogue. Only when individual study failed did students opt for interpersonal dialogue. This finding conflicts with the assumed importance often ascribed to interpersonal dialogue by some distance education theorists. 相似文献

Two studies investigating the influence of a humorous atmosphere on students' creativity scores are presented. In the first study 78 adolescents were shown humorous film clips and given a task requiring them to write captions for cartoons. A creativity test was subsequently administered to these students and to a control group. In the second study, Form A of the Torrance creativity test (TCT) with standard instructions was given to 130 adolescents. These were then divided into two groups, one experimental and one control. The experimental group was instructed to complete Form B of the TCT with humorous responses, while the control group was instructed to proceed as before. Results of both experiments showed that a humorous atmosphere significantly increases creativity scores. Several explanations for the findings were proposed and the practical applicability of the results in education were stressed. 相似文献

This paper addresses the relationship between theory and practice in preservice teacher education. Using Giroux's (1994) distinction between a "pedagogy of theory" and a "pedagogy of theorizing", it explores the difference between prospective teachers learning about education in teacher preparation courses and learning from it by critically reading the educative process in their own preservice education classrooms. Challenging the idea that preservice education is merely preparation for a practicum conducted elsewhere and in the future, this paper proposes that teacher education classrooms become practicum environment in-and-of-themselves, where practice gets theorized and theory is not only considered for practice but is indeed practiced as it interrogates practice. 相似文献

Christianity and its legacy in education 总被引：1，自引：0，他引：1
Much of the discussion regarding religion and schooling in the US has been limited to ideological clashes surrounding the role of the courts and, ostensibly, the much litigated issue of prayer in schools. This comes at the expense of an examination of deeper curricular issues rooted in language and school mechanisms borne of historical consequences. The authors seek to reframe the discussion of religion and schooling, arguing that to suggest that the removal of explicit prayerfulness equates to the cleansing of US public education of its religious character is facile and ahistorical. They suggest, instead, that religion remains in the language, practices, and routines of schooling but also in conceptions of the “’child” ‘ and assumptions about the role of schools emanating from such conceptions. Evoking the notion of pentimento, the piece seeks to elucidate the Judeo-Christian character of schooling in the US as a way of re-imagining discussions regarding the relationship between religion and/as curriculum. The piece concludes with a discussion of the implications of such an examination for curriculum studies and teacher education. 相似文献

This research examined how students at the Open University of Israel studied from video recordings of lectures. At the semesters end, seven history students were interviewed in order to trace their experiences, learning strategies and preferences. It was found that (1) reading comprehension strategies are inappropriate for viewing comprehension, (2) presumed theoretical advantages associated with instructional video may in fact be disadvantages, (3) the medium does indeed influence the message, (4) mismatching medium and message may have deleterious results on students cognitive and affective outcomes and (5) surface-level orientations to study may be hindered by video. 相似文献
