【摘要】：數(shù)字化資源是信息化教學(xué)重要的組成部分。其中,視頻資源是課堂教學(xué)中常用的資源形式,其對課堂教學(xué)的促進(jìn)作用已被廣為認(rèn)可,然而,視頻資源在課堂的應(yīng)用仍然存在一些不足之處：從使用出發(fā)點(diǎn)看,視頻資源作為一種單純的輔助性的資源加以應(yīng)用,呈現(xiàn)孤立,表現(xiàn)單一；從資源處理上看,視頻資源采用了“拿來主義”的應(yīng)用觀,缺乏針對課堂教學(xué)的有效的處理方式；從資源整合上看,視頻資源與其他資源的整合不夠深入,相互之間缺乏內(nèi)在的關(guān)聯(lián)；從應(yīng)用理論上看,視頻資源的應(yīng)用缺乏有效的策略指導(dǎo),重視操作,但缺乏理論支撐。 顯然,當(dāng)前課堂教學(xué)中視頻資源應(yīng)用的觀念比較陳舊,視頻資源的應(yīng)用還不夠充分；視頻應(yīng)用理論的研究不夠深入,尤其是缺少從教學(xué)策略的層面研究視頻資源的有效應(yīng)用；視頻策略的研究缺少對策略應(yīng)用支持系統(tǒng)的關(guān)注,在一定程度上限制了策略應(yīng)用的有效性。因而,視頻資源本身的教育能量沒有實(shí)現(xiàn)最大化。 本文主要的工作包括以下三個方面： 首先,結(jié)合多媒體學(xué)習(xí)理論和教學(xué)策略理論的研究成果,提出了五項(xiàng)基于視頻的課堂教學(xué)策略,包括：幀捕捉的應(yīng)用策略；視頻切片的應(yīng)用策略；即時關(guān)聯(lián)的應(yīng)用策略；視頻批注的應(yīng)用策略以及視頻蒙板與縮放的應(yīng)用策略。并在一般教學(xué)策略模型的基礎(chǔ)上,提出了基于視頻的課堂教學(xué)策略模型,使視頻策略成為整個教學(xué)進(jìn)程的有機(jī)組成部分。 其次,基于多媒體學(xué)習(xí)的知識建構(gòu)觀,對本文提出的視頻教學(xué)策略,有針對性的設(shè)計(jì)了相應(yīng)的策略應(yīng)用支持系統(tǒng)。分析了系統(tǒng)的功能需求,包括：多幀捕捉、視頻切片編輯與應(yīng)用、內(nèi)容即時關(guān)聯(lián)、視頻畫面標(biāo)記等；設(shè)計(jì)了系統(tǒng)的整體框架和各功能模塊。 最后,在Microsoft Visual Studio 2008開發(fā)環(huán)境下,運(yùn)用Visual C++技術(shù)完成系統(tǒng)的開發(fā)工作。其中,運(yùn)用MFC(Microsoft Foundation Classes)的多文檔結(jié)構(gòu)構(gòu)建系統(tǒng)的整體框架；運(yùn)用VFW(Video for Windows)開發(fā)包實(shí)現(xiàn)視頻文件的基本應(yīng)用；借助ActiveX控件技術(shù)實(shí)現(xiàn)對多種文檔資源的支持。系統(tǒng)主要實(shí)現(xiàn)了幀捕捉、視頻切片以及即時關(guān)聯(lián)三個模塊的功能。
[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.
