论“三角形法”解平衡问题的局限性

共点力平衡问题是实际生活中最常见的问题之一,涉及的主要知识是共点力平衡条件的应用,其中,三力平衡问题是现行高中物理教学中的重点内容,而如何处理这类问题又是高中物理教学的难点.在高中物理教学中,解三力平衡问题常用的方法有＂三角形法＂和＂正交分解法＂.所谓＂三角形法＂是指在研究三力平衡时,根据任意两     

对“教后反思”有效性的思考

＂教后反思＂是教师提高个人业务水平的一种有效手段,但一些教师对此存在着应付心理,虽然＂教后反思＂的栏目写得很满,其实没有真正从根本上反思自己的教学行为。因此,探索有效进行教后反思势在必行。     

教学反思:概念、意义及其途径

反思就是对自己经历过的思想、心理感受及行为的体验和思考。教学反思是指教师在教学过程中通过教学内省、教学体验、教学监控等方式,辩证地否定主体的教学观念、教学经验、教学行为的一种积极的认知加工过程,其目的在于改善教师的教学。教学反思之所以受到重视,是出于对教师工作绩效提高的要求、对教师教育职业化倾向的要求以及教师培训理性化的要求。教学反思的途径主要有录像反思、日记反思、从学习者角度反思、与同事及专家的交流中反思以及通过向学生征询意见反思。     

国外教师职业认同与专业发展研究述评

教师职业认同是教师专业化发展需要奠定的心理基础.职业认同是多方面、动态、变化发展着的过程.其中,自我和反思是职业认同中基本的要素,通过自我反思,教师把个体经验与社会期望结合起来,形成他们作为教师的自我形象.     

高校体育教师能力结构研究

所谓能力,是指人顺利完成某种活动任务时经常、稳固地表现出来的心理特征,是知识、技能和智力的整体效应.能力结构,则是指把各种能力的集合作为一个系统整体考虑时所呈现出来的系统结构属性.高校体育教师的能力结构包括教学能力;体育科研能力;指导学生身体锻炼的能力;训练能力;教育能力;保健能力;专项训练与专项理论能力共七种能力.能力具有创造性.弄清楚高校体育教师的能力结构,对于高校体育教师提高和发展综合能力,建设高校体育师资队伍具有重要的积极指导作用.     

Enriching preservice teachers’ critical reflection through an international videoconference discussion

The concepts of reflection and reflective practice have become the core of many teacher education programmes, with critical reflection as the goal for many teacher educators. This study examined the use of a videoconference discussion in an instructional methodology course as a means to enrich the process of reflection and encourage critical reflection. Critical action research methodology was used by the researchers to evaluate the addition of videoconferencing to a model of scaffolded reflection which was already part of the course. The findings suggest that the introduction of a videoconference discussion to the scaffolded reflection model enriched critical reflection on four topics: technology use, multicultural curriculum and instruction, censorship of web-based resources, and accountability and assessment. The discussion of these topics allowed the preservice teachers to think about their own agency, and the affordances and constraints of their school context. Implications for using videoconferencing for critical reflection are provided for teacher educators.

Relationship Between Reflective Disposition Toward Teaching and Effective Teaching

Abstract

The author demonstrated that a reflective disposition toward teaching was related to effective teaching especially in the domains of instructional behavior, classroom organization, and teacher expectation. Data used to test the hypothesis were composed of reflective disposition scores earned by teacher candidates (N = 55) and effective teaching scores given teacher candidates by their field instructors. Reflective disposition consisted of 6 components: the composite of reflective disposition and the composite of effective teaching, reflection on what teachers should know and be able to do, reflection on teaching, reflection on learning, reflection on the relationship between learning and teaching, and reflection on what it would be like to be a teacher in the classroom. Effective teaching consisted of 5 components: the composite of effective teaching, classroom management, instructional behavior, classroom organization, and teacher expectations.     

试论培养反思型教师的思维态度——杜威“反思性思维”的启示

教师反思是教师专业发展的重要方式,同时,在教师教育、课堂教学等领域也扮演着重要角色。近年来的相关研究及改革把培养反思型教师推向了前所未有的高潮,但本文认为,教师反思首先要在思维态度上有所改观,才会有实质性的突破。依据杜威的反思性思维,尝试论述培养反思型教师的思维态度的重要性及方法,希望能有一些参考价值。

Facilitating critical reflection on practice through collaborative research

This paper emanates from a study that analysed the critical reflection of teacher researchers as they talked about their investigations of the home cultures and literacies of a small group of children from socioculturally diverse family contexts. The collaborative research enterprise was undertaken by university and teacher researchers. The important role that collaborative teacher research and social interaction played in the critical reflection and co-construction of professional understandings in the project is the focus of this paper. The teacher researchers’ theorising about the complexity of their work as a result of the collaborative enterprise is discussed. Through the voiced research and critical reflection of the teachers, it has become obvious that their life’s experiences and resources are powerful in their pedagogical theorising. Teachers comment on the way in which they are positioned by ‘the system’ as technicians and how they experience tension between their own professional and primary discourses and that of the system. It is suggested that teachers be given opportunity within their work sites to enter the conversations about curriculum, pedagogy and change in knowledgeable and meaningful ways that are grounded in collaborative reflection and research. This paper explores the critical reflection and the social construction of new understandings about the complexity of teachers’ work that occurred in a collaborative research project carried out by a university-based researcher and four school-based early years teacher researchers. It will show how the collaborative research process facilitated critical reflection on previously unquestioned or unconsidered issues about the teachers’ work. The paper has been written by the university researcher under the watchful eye of the teacher researchers who want to remain anonymous. Their pseudonyms have been used. When the terms of this project were negotiated among the group, it was agreed that the voices of the teachers would always be reported authentically and anonymously. It was also agreed that any theorising, integrated language analysis (Freeman, 1996) or reporting that might be carried out, would be done by the university researcher That is not to say that the teacher researchers have not spoken about their involvement in the project to colleagues in professional development forums and conferences. Nor is to say that the teachers were not privy to the analysis process. It is to say that written reports for publication are to be done by the university researcher.
