【摘要】：数字化资源是信息化教学重要的组成部分。其中,视频资源是课堂教学中常用的资源形式,其对课堂教学的促进作用已被广为认可,然而,视频资源在课堂的应用仍然存在一些不足之处：从使用出发点看,视频资源作为一种单纯的辅助性的资源加以应用,呈现孤立,表现单一；从资源处理上看,视频资源采用了“拿来主义”的应用观,缺乏针对课堂教学的有效的处理方式；从资源整合上看,视频资源与其他资源的整合不够深入,相互之间缺乏内在的关联；从应用理论上看,视频资源的应用缺乏有效的策略指导,重视操作,但缺乏理论支撑。 显然,当前课堂教学中视频资源应用的观念比较陈旧,视频资源的应用还不够充分；视频应用理论的研究不够深入,尤其是缺少从教学策略的层面研究视频资源的有效应用；视频策略的研究缺少对策略应用支持系统的关注,在一定程度上限制了策略应用的有效性。因而,视频资源本身的教育能量没有实现最大化。 本文主要的工作包括以下三个方面： 首先,结合多媒体学习理论和教学策略理论的研究成果,提出了五项基于视频的课堂教学策略,包括：帧捕捉的应用策略；视频切片的应用策略；即时关联的应用策略；视频批注的应用策略以及视频蒙板与缩放的应用策略。并在一般教学策略模型的基础上,提出了基于视频的课堂教学策略模型,使视频策略成为整个教学进程的有机组成部分。 其次,基于多媒体学习的知识建构观,对本文提出的视频教学策略,有针对性的设计了相应的策略应用支持系统。分析了系统的功能需求,包括：多帧捕捉、视频切片编辑与应用、内容即时关联、视频画面标记等；设计了系统的整体框架和各功能模块。 最后,在Microsoft Visual Studio 2008开发环境下,运用Visual C++技术完成系统的开发工作。其中,运用MFC(Microsoft Foundation Classes)的多文档结构构建系统的整体框架；运用VFW(Video for Windows)开发包实现视频文件的基本应用；借助ActiveX控件技术实现对多种文档资源的支持。系统主要实现了帧捕捉、视频切片以及即时关联三个模块的功能。
[Abstract]:Digital resources are an important part of information-based teaching. Among them, video resources are commonly used in classroom teaching, and its promotion to classroom teaching has been widely recognized. However, there are still some shortcomings in the application of video resources in the classroom: from the point of view of the use of video resources, As a simple auxiliary resource, video resources are isolated and single. In terms of resource processing, video resources adopt the "borrowlism" view of application, and lack of effective ways to deal with classroom teaching. From the view of resource integration, the integration of video resources and other resources is not deep enough, and there is no intrinsic connection between them; from the application theory, the application of video resources lacks effective strategy guidance, attention to operation, but lack of theoretical support. Obviously, the concept of video resource application in classroom teaching is rather old, the application of video resource is not enough, the research of video application theory is not deep enough, especially the effective application of video resource from the level of teaching strategy. The research of video strategy lacks attention to the policy application support system, which limits the effectiveness of policy application to a certain extent. Therefore, the educational energy of video resource itself is not maximized. The main work of this paper includes the following three aspects: firstly, combined with the research results of multimedia learning theory and teaching strategy theory, five video-based classroom teaching strategies are proposed, including: frame capture application strategy; The application strategy of video slicing; the application strategy of real-time correlation; the application strategy of video annotation; and the application strategy of video mask and scaling. On the basis of the general teaching strategy model, the video-based classroom teaching strategy model is proposed, which makes the video strategy become an organic part of the whole teaching process. Secondly, based on the knowledge construction view of multimedia learning, this paper designs the corresponding strategy application support system for the video teaching strategy proposed in this paper. The functional requirements of the system are analyzed, including multi-frame capture, video slice editing and application, content real-time correlation, video picture marking and so on, and the overall framework and functional modules of the system are designed. Finally, under the Microsoft Visual Studio 2008 development environment, the Visual C technology is used to complete the development of the system. The whole frame of the system is constructed by using the multi-document structure of MFC (Microsoft Foundation Classes), the basic application of video files is realized by using VFW (Video for Windows) development kit, and the support of various document resources is realized by means of ActiveX control technology. The system mainly realizes the functions of frame capture, video slicing and real-time association.
