Drawing upon research into a case study of teacher inquiry in one school in Queensland, Australia, recent theorising into professional practice, and relevant literature on teachers’ learning, this article reveals the complexity and particularity of teacher inquiry processes in support of teachers’ learning. Specifically, the research reveals how particular actions, dialogue, and relationships collectively constitute a practice of teacher inquiry which seeks to promote substantive teacher-led learning. The research draws upon a group of Year 5 teachers engaged in collective inquiry into their work in what was described as an “Inquiry Cycle” approach in a school in northern Queensland, during a period of support for substantial curriculum reform. The research reveals the Inquiry Cycle approach as characterised by specific actions, dialogue, and relationships – “doings,” “sayings,” and “relatings” – productive of the development of a learning culture focused on significant curriculum reform; overt support for whole-school “explicit” approaches to teachers’ pedagogies; and active/robust critique of data-focused assessment processes. The research reveals necessary texture and detail in support of teachers’ learning, and the specific circumstances and contextual “arrangements” that help constitute this learning.  相似文献

Claims have been made that computer mediated communication (CMC) is a potentially highly participatory and democratic medium because it reduces the requirement to interrupt or wait your turn to speak. Such aspects of discussion have been shown to be relevant to differences in male and female participation in group discussions. In general, men have been found to take more turns and to speak longer than women in mixed sex groups. Men are also said to characteristically speak about things, take centre stage and give opinions. Women on the other hand are more likely to emphasis people rather than things, and to build and maintain relations in the way they talk. These two styles have been described as report talk of men and rapport talk of women.In this paper we describe some preliminary findings on the impact of using CMC and its effect on traditional gender participation differences. We look first at turn taking by men and women in computer conferences, and then how women in particular experience differences in the kind of contributions made to the conferences by men and women. Finally, we look at the actual contributions made by men and women and the extent they differ from each other.  相似文献

Abstract

Audio teleconferencing is a distance learning delivery system that has often been overlooked by educational institutions and other organizations. However, the trend toward adoption of “high‐end” (and high cost) delivery systems is giving way to a new trend toward appropriate selection of a delivery system based on course content, course design, and intended audience. This article takes a close look at audio teleconferencing as a viable option for many distance learning situations, discusses the importance of the audio component in distance learning, and suggests management and delivery strategies for organizations considering this medium.  相似文献

This article draws on Bourdieu’s field theory and related concepts of habitus and capitals, to explore policy implementation in relation to a particular case of teacher professional development in Queensland, Australia. This implementation process is described as an effect of the interplay between what is called the policy field and the field of teachers’ work. The policy field demonstrates intra‐field tensions between the federal Quality Teacher Programme (QTP) and a raft of state policies, particularly those associated with the Queensland meta‐policy, Queensland State Education 2010 (QSE2010). To investigate the effects of this complex policy ensemble, the article draws upon the experiences of principals and a group of teachers engaged in professional development across a cluster of six schools in south‐east Queensland, Australia. The specific focus is on the ‘Curriculum Board’, a cross‐school body created by the principals in the participating schools, and its mediated work in policy implementation and teacher learning. The article analyses the effects of the involvement of the principals in the creation of the board, the limiting impact of QTP requirements to involve consultants rather than support for teacher release, and the limited influence of the board on teacher learning and policy implementation in the individual schools. By doing so, the analysis shows the disjunctions between the logics of practice of the policy field and that of teachers’ work, and the ways in which the differing habitus of principals and teachers and teacher members of the board affected teacher learning and policy implementation. It is argued that effective implementation requires learning within and across fields, and more reflexive habitus of policy makers, principals and teachers.  相似文献

abstract

Using data collected from 120 students enrolled in nine sections of an undergraduate technical communication course, this study found a number of statistically significant associations between students' learning styles, as defined by the Index of Learning Styles, and nine measures evaluating both academic performance and student preference. The study also measured student performance in collaborative and self-directed versions of the course, as well as full and summer sessions. Reflective learners were found to be the most successful online learners, excelling in collaborative, as well as self-directed versions of the course. Sequential learners also outperformed global learners. Learning styles were not a significant factor in summer-session courses.  相似文献

Using the insights of the French sociologist, Pierre Bourdieu, this article considers the role of the science department chair in the reform of school science education. Using Bourdieu’s ‘thinking tools’ of ‘field’, ‘habitus’ and ‘capital’, we case study the work of two teachers who both actively pursue the teaching and learning of science as inquiry. One teacher, Dan, has been a department chair since 2000, and has actively encouraged his department to embrace science as inquiry. The other teacher, Leslie, worked for one year in Dan’s department before being transferred to another school where science teaching continues to be more traditional. Our work suggests that there are three crucial considerations for chairs seeking to lead the reform of science teaching within their department. The first of these is the development of a reform-minded habitus, as this appears to be foundational to the capital that can be expended in the leadership of reform. The second is an understanding of how to wield power and position in the promotion of reform. The third is the capacity to operate simultaneously and strategically within, and across, two fields; the departmental field and the larger science education field. This involves downplaying administrative logics, and foregrounding more inquiry-focused logics as a vehicle to challenge traditional science-teaching dispositions—the latter being typically dominated by concerns about curriculum ‘coverage’.  相似文献

Abstract

It is argued that previous studies of active flexibility have not achieved experimental control. An experiment then is described which achieved experimental control by using daily flexibility training over a 7-day period.

Forty-two female subjects were randomly assigned to one of six treatment groups or a control group. The six treatment groups received proprioceptive neuromuscular facilitation training for six consecutive days with isometric contraction periods of 0 sec, 3 sec, or 6 sec. Three of the treatment groups followed an active regime (concentric contraction of the agonists) and three a passive regime. All subjects were pretested for active flexibility on Day 1. They were also posttested after training on Day 6, and without training on Day 7. A two factor multivariate analysis of covariance with trend analysis on the period of isometric contraction factor indicated a significant positive linear trend for this factor, approximate F(2, 28) = 7.90, p < .002, together with a significant interaction between this linear trend and the active-passive regime factor, approximate F(2, 28) = 3.81, p < .034. Follow-up tests revealed that this interaction was due to larger gains in active flexibility being associated with longer periods of isometric contraction in the active groups, but not in the passive groups.  相似文献

Abstract

We investigated narcissism as a moderator of social loafing on a physical performance task. High and low narcissistic individuals twice performed a cycling task in same-sex teams of three: once when identifiability was low; and once when identifiability was high. A significant interaction between narcissism and identifiability was revealed, F(1, 40) = 4.09, p < .05, η2 = .09 for performance. Follow-up tests indicated that high narcissists' performance significantly increased with greater identifiability, whereas low narcissists displayed no such performance differences. Results suggested that this effect was due to an increase in narcissists' on-task effort (ratings of perceived exertion and heart rate) when they knew that their performance was to be identified.  相似文献

Abstract

In the current experiment, we examined optimal focus for novices during a movement sequence in which performance was measured on accurate movement form/technique. A novel gymnastics routine was practiced under either an internal skill-relevant, internal skill-irrelevant, external, or no attention focus. Retention and transfer tests were then completed. During acquisition, adopting an internal irrelevant focus significantly improved performance, whereas an external focus degraded performance. There were no significant group differences in the retention and transfer tests. This suggests that learning of movement form/technique did not benefit from a specific focus of attention. The results are interpreted via an attentional capacity viewpoint and the notion that form tasks do not always contain obvious movement effects central to common coding and the constrained action hypothesis.  相似文献
