视频资源作为数字化板书,可发挥动态批注的功能,呈现知识信息的连贯性,利用视频的即时关联特征体现教学内容的相互依存关系,促使不同教学资源建立视觉上的联系。在英语课堂教学中,教师需要改变传统视频资源的粗加工方式,不再以知识进给量代替内容关联的深度,为课堂教学提供间接或直接的仿真语境,通过“化整为零”和“按需分配”的视频切割策略应对课堂教学中个别化的、具体化的技能分解和案例分析需要,努力探索视频批注应用、关联应用以及切片应用的教学优化策略。
As a digital bulletin, video resources can play the role of dynamic annotation, present the consistency of knowledge and information, use video’s instant relevancy to reflect the interdependencies of teaching contents, and promote the visual connection between different teaching resources. In the English classroom teaching, teachers need to change the traditional way of processing video resources, instead of using the amount of knowledge to replace the depth of content relevance, provide indirect or direct simulation of classroom teaching context, through “And” on-demand "video cutting strategies to address the individualized, materialized skill decomposition and case analysis needs of classroom teaching, and to explore teaching optimization strategies for video annotation applications, associated applications, and slice applications.
