The goal of this study was to explore the processes of group role formation in online class settings. Qualitative analysis was used to code chat logs and discussion threads in six undergraduate Family and Consumer Sciences online courses that required online group projects. Four themes related to the process of group role formation emerged: testing the waters, apologies as being nice, tag – you’re it, and struggling to find one’s role. Students created roles of leader, wannabe, spoiler, agreeable enabler, coat‐tails, and supportive worker as the group process evolved over the course of the semester. Results lend support for a balance between allowing students to create and experience roles on their own and faculty assignment of roles. Questions are raised related to faculty approaches toward directing and scaffolding the group process. 相似文献

In this collaborative self-study, two teacher educators examine their experiences of working in new international contexts and the impact of those experiences on their professional learning and identities. Mandi moved from a major research university in one country to another, while Judy co-led a group of pre-service teachers on an international practicum for three weeks each year for three years. Using the concept of boundary crossing as a theoretical and analytical framework, each teacher educator identified a boundary-related critical incident or experience that occurred during her work in new international contexts. Through individual and collaborative analysis of their critical incidents, they found that working as a teacher educator in new international contexts involves the crossing and re-crossing of multiple personal, professional, linguistic and cultural boundaries. Working in these boundary spaces involved learning how to negotiate new kinds of relationships with colleagues and students, manage changed roles and responsibilities and, ultimately, a search for a renewed sense of self, as each sought to understand herself differently within a new professional context. 相似文献

Stimuli that signal the absence of reinforcement are paid more attention than are irrelevant stimuli
According to established theories of attention (e.g., Mackintosh, 1975; Sutherland & Mackintosh, 1971), simple discriminations
of the form AX+ BX- result in an increase in attention to stimuli A and B, which are relevant to the outcome that follows
them, at the expense of X, which is irrelevant. Experiments that have apparently shown such changes in attention have failed
to determine whether attention is enhanced to both A and B, which signal reinforcement and nonreinforcement, respectively,
or just to A. In Experiments 1 and 2, pigeons were trained with a number of discriminations of the kind AX+ BX-, before compounds
that had been consistently nonreinforced were involved in a subsequent discrimination. Both experiments provided support for
theories that propose that more attention is paid to stimuli that consistently signal nonreinforcement than to irrelevant
stimuli in simple discriminations. 相似文献

This research is part of an on-going investigation into student teachers' perceptions of theory and practice within Initial Teacher Training [ITT] and beyond. Respondents were drawn from a number of specialist ITT providers, and supple-mented from other sources. [1] The enquiry grew out of earlier research into examination courses in Key Stage 4 and teachers' dependency on 'orthodox' approaches and content. [2] The likelihood of challenging or breaking down this dependency seemed to rely on student teachers' ability to critique current practices and speculate as to alternatives, which is made more problem- atic because of the drastic reduction of time allocation in ITT. [3] This report in part is predicated on the belief that the enforced, crude division of time spent in, and out, of schools polarises theory and practice in the minds of students. This, in turn, tends to undermine the opportunities to explore and experiment with teaching and learning styles, and the degree to which students value and employ theory and make use of, and extend, their subject knowledge.

This paper describes and analyses Swedish curriculum theory and research in a 20year perspective in relation to the changes in the comprehensive school system and the decline of the welfare state. It is argued that the break-up of the strong triangle' between the educational research community, the former National Board of Education and the Ministry of Education, which was essential in the implementation of the comprehensive school in the 1960s and in the promotion of research and theory on the curriculum, began in the late 1970s and early 1980s. Some of the consequences of this change are analysed to highlight a changed agenda for curriculum theory and research in terms of a recontextualization not only of the curriculum objects but of curriculum theory and research itself. 相似文献

Group size and organisational conditions for children’s learning in preschool: a teacher perspective
Sonja Sheridan Pia Williams Ingrid Pramling Samuelsson 《Educational research; a review for teachers and all concerned with progress in education》2013,55(4):379-397
Background:?There is a limited amount of research about group size in preschool, and how it impacts on teachers’ working conditions and their ability to support children’s learning and knowledge development in line with curriculum intentions.Purpose:?From a perspective on quality, this article examines the organisational conditions for children’s learning in preschool in relation to group size. The questions at issue are: how do teachers explain how they organise the child group and the learning environment in preschool, and why?Sample:?The sample consists of 12 preschools from different parts of Sweden. The preschools selected for the study are stratified in order to represent small and large group sizes in Swedish preschools as defined by the Swedish National Agency for Education. The sample contains both urban and rural regions and represents districts that differ geographically, demographically, ethnically, and which include varied socioeconomic structures. The 12 preschools had children in three age groupings: 1–3, 3–5 or 1–5. The number of children in the participating preschools ranged from 12 children to 45 children, with seven of the preschools having more than 30 children in their groups.Design and method:?The article is based on interactionist perspectives, Bronfenbrenner’s ecological systems theory, a critical ecology of the early childhood profession, theories of children’s learning, and four dimensions of pedagogical quality. Together, these theoretical perspectives contribute to an understanding of the relationships between policy issues, educational goals, group size and teachers’ competence in organising and creating conditions for children’s learning. Semi-structured interviews were conducted with two teachers from each of the 12 preschools. The interviews lasted between 40–60 minutes and were recorded and transcribed verbatim. The analytical process was conducted in three steps and can be described as an analytical process of abduction. The four dimensions of pedagogical quality were used as analytical lenses to discern and understand critical aspects related to the teachers’ understanding of group size.Result: Irrespective of group size, most of the children participate in different group constellations throughout the day, some organised by the teachers and some by the children themselves. Teachers’ competence to organise the children in such ways that good conditions for learning were created, differed between preschools, and depended on the teachers’ approach, which can be described as either intentional or unintentional learning.Conclusion: Teachers’ organisational approaches influence the quality of the preschool and conditions for children’s learning in distinct ways. 相似文献

In the past 20 years a substantial literature has accumulated on intervention with deprived preschool children. The unrealistically high hopes of the 1960s have largely been replaced by a more sober analysis of the relevant factors in social disadvantage. One of the more recent developments has been an approach through the skills and attitudes of those adults most concerned with under‐fives, including the staff of pre‐school centres and parents. In Britain the available research has been focussed almost exclusively on nursery schools, neglecting the situation of day nurseries, many of whom cater to deprived inner‐city areas. The present research was an attempt to explore the possibilities and monitor the problems of working with the trained staff of six London day nurseries. Three programmes were introduced ‐‐ a developmental assessment form, a series of workshops on coping with behaviour problems and workshops on language development. The project is discussed in terms of the particular difficulties for intervention posed by day nursery practice, the achievements and problems of this project and general implications for action research as a method. 相似文献

Recent advances in testing mediation have found that certain resampling methods and tests based on the mathematical distribution of 2 normal random variables substantially outperform the traditional z test. However, these studies have primarily focused only on models with a single mediator and 2 component paths. To address this limitation, a simulation was conducted to evaluate these alternative methods in a more complex path model with multiple mediators and indirect paths with 2 and 3 paths. Methods for testing contrasts of 2 effects were evaluated also. The simulation included 1 exogenous independent variable, 3 mediators and 2 outcomes and varied sample size, number of paths in the mediated effects, test used to evaluate effects, effect sizes for each path, and the value of the contrast. Confidence intervals were used to evaluate the power and Type I error rate of each method, and were examined for coverage and bias. The bias-corrected bootstrap had the least biased confidence intervals, greatest power to detect nonzero effects and contrasts, and the most accurate overall Type I error. All tests had less power to detect 3-path effects and more inaccurate Type I error compared to 2-path effects. Confidence intervals were biased for mediated effects, as found in previous studies. Results for contrasts did not vary greatly by test, although resampling approaches had somewhat greater power and might be preferable because of ease of use and flexibility. 相似文献

ABSTRACTThis article explores the influential role of planning on recognition-primed decision-making. Considerable prior thinking occurs and there is a need to trace and account for the cognitive processes that precede and guide decisions in dynamic outdoor environments. Seven expert leaders from four countries were interviewed about memorable decisions made on outdoor journeys with an educational focus on land, sea and ice. Four stages of planning were identified: (1) long-term preparation; (2) formal leadership meetings; (3) day-by-day planning on route and (4) thinking immediately prior to the event. The stages sequentially capture the planning progression, illuminating the cognitive processes at each stage to culminate in option selection. In each decision situation, planned goals and actions were implemented through the creation and re-creation of micro-plans. As windows of opportunity presented themselves, the flexible execution of plans was a key feature. Planning provided the solid bedrock upon which decisions were made. 相似文献
