Research On Design Strategy And Application Of Instructional Video For Online Courses

Based on the rapid development of online education in China,instructional video has become the most important resource form of online courses,but the quality is uneven.Therefore,the research on the design strategy of online instructional video is carried out.This paper constructs an online course instructional video analysis framework from three dimensions of instructional content,instructional design and media technology,and then collects the online course instructional video design strategies proposed by seven scholars at home and abroad,and systematically summarizes these strategies according to the framework.Then it mainly analyzes the data of 50 winning courses on the platform of online courses in China from the perspective of media technology,understands the current situation of online course instructional video production in China,summarizes the excellent practical experience,and complements the online instructional video design strategy.Finally,some strategies are applied to the design and production of micro course design and practice,and two online instructional videos are made.After research,this paper finally obtained 63 video design strategies related to video instructional content,instructional design and media technology.Among them,there are 4 strategies related to instructional content,which respectively involve four aspects:course description,content goal consistency,content segmentation and content arrangement.There are 25 strategies related to instructional design,including instructional strategies,learning guidance,video types,exercises and feedback.There are a total of 34 strategies related to media technology,including teacher picture,instructional content picture,background picture and sound.This thesis is divided into the following six chapters:The first chapter mainly describes the research background,research purpose and significance,through literature review to clarify the research status at home and abroad,determine the research content and methods of this paper.The second chapter mainly defines the concept of online course and instructional video,and combs the three theoretical basis of this study:cognitive theory of multimedia learning,cognitive load theory and learning motivation theory.The third chapter analyzes the authoritative and representative mooc video analysis framework in China and compares it,extracts the key dimensions,and constructs the online instructional video analysis framework according to the multimedia teaching theory and teaching design.The fourth chapter mainly uses the framework of online course instructional video analysis,focusing on the analysis of 50 excellent courses on the online course platform in China from the aspects of instructional video duration,video type,teacher picture,instructional content picture,etc.,summarizes the key points of online course instructional video design,and improves the instructional video design strategy.The fifth chapter mainly uses the proposed online course instructional video design strategy,designs and produces the course "micro-course design and practice",carries out the application practice of the teaching video design strategy,and verifies the effectiveness of the strategy.The sixth chapter is the summary of the whole research content,reflecting on the shortcomings,and looking forward to the research.
