职前教师教育中视频案例教学的研究 总被引:2,自引:0,他引:2
在职前教师教育中采用视频案例教学是发展师范生教学技能和提高教师专业能力的一个新方法。本文在梳理教师教育中视频案例教学重要概念的基础上,考察了国内外教师教育中视频案例教学研究的现状,最后作者提出了应用于职前教师教育中的视频案例学习环境创设框架,它包括有机联系的六个要素:案例与资源、活动、工具、支架、共同体和评价。 相似文献

现代语境下的影像具有怀旧、凸显身体、暴力血腥等多重特征,它同时对大众特别是青少年构成了低智性致幻、暴力性刺激、道德性毁灭等负面影响,当代青少年有必要通过影视艺术和课程的学习,通过相应的校园文化活动等方法与途径,达成道德自律。 相似文献

This paper examines the video-based pedagogical practices of Terry (pseudonym), a head coach of a professional junior academy squad. Data were collected through 6 in-depth, semi-structured interviews and 10 field observations of Terry’s video-based coaching in situ. Three embracing categories were generated from the data. These demonstrated that Terry’s video-based coaching was far from apolitical. Rather, Terry strategically used performance analysis technologies to help fulfil various objectives and outcomes that he understood to be expected of him within the club environment. Kelchtermans’ micropolitical perspective, Callero’s work addressing role and Groom et al.’s grounded theory were primarily utilised to make sense of Terry’s perceptions and actions. The findings point to the value of developing contextually grounded understandings of coaches’ uses of video-based performance analysis technology. Doing so could better prepare coaches for this aspect of their coaching practice. 相似文献

A CD-ROM consisting of videos of two lessons by different teachers demonstrating exemplary science teaching was used to elicit,
develop and track the changing conceptions of good science teaching of student teachers enrolled for the one-year Postgraduate
Diploma in Education (PGDE) at several stages during the programme. It was found that the videos acted as an effective probe
to elicit student teachers’ conceptions and had significant impact on those conceptions at different stages of the programme
through the provision of teacher models demonstrating exemplary teaching. The experience has extended novice teachers’ awareness
of alternative teaching methods and approaches not experienced in their own schooling, broadened their awareness of different
classroom situations, provided proof of existence of good practices and prompted them to reflect on their current conceptions
of good science teaching. Most importantly, the strategy of asking student teachers to watch the same videos on three separate
occasions at different times of the course was recognized by them as a crucial element in facilitating their reflection on
their changing conceptions of good science teaching.
PGDE is the standard form of pre-service teacher education in Hong Kong. It provides qualified teacher status within Hong
Kong. Student teachers enrolled for the PGDE have completed a relevant undergraduate degree. 相似文献

本文提出了一种新的在MPEG-4编码过程中提高实时性的算法。算法采用双重筛选机制,充分利用了运动估计的结果提取运动对象。首先在运动估计过程中加入背景优先准则进行第一重筛选;然后根据运动估计后宏块的最小平均绝对差值分利用区域自适应门限进行第二重筛选,从而获得运动区域掩模;最后对掩模进行形态滤波和填充消除噪声点,最终得到运动区域。算法分别在硬件和软件平台上进行测试,结果表明提出的算法得到了理想的分割效果,较传统的在编码前进行运动对象提取的方法实时性大大提高了。 相似文献

中国近期影视后现代性强化了世俗愿望的追求,拆解了英雄创业的神话,在放遂各种政治与道德权威话语的同时,破坏了具有历史主义特征的精神模式,使影视更加贴近百姓的感受经验。 相似文献

The purpose of this study is to examines the relationship between the communicative approach of classroom talk and the modes of representations used by science teachers. Based on video data from two physics classrooms in Singapore, a recurring pattern in the relationship was observed as the teaching sequence of a lesson unfolded. It was found that as the mode of representation shifted from enactive (action based) to iconic (image based) to symbolic (language based), there was a concurrent and coordinated shift in the classroom communicative approach from interactive–dialogic to interactive–authoritative to non-interactive–authoritative. Specifically, the shift from enactive to iconic to symbolic representations occurred mainly within the interactive–dialogic approach while the shift towards the interactive–authoritative and non-interactive–authoritative approaches occurred when symbolic modes of representation were used. This concurrent and coordinated shift has implications on how we conceive the use of representations in conjunction with the co-occurring classroom discourse, both theoretically and pedagogically. 相似文献
