摘　　要：视频资源的教学应用随着教育信息化的发展而日益广泛。为有效解决视频资源在教育应用中数量庞大且离散、有效利用率不高等问题,本研究设计基于知识元的视频聚合模型——"知识元—视频元—视频节点—视频聚合网",从而使视频学习资源具有良好的"描述结构"和"组织模式"。研究以《中国当代文学》课程为对象,进行混合式教学实验,从基于知识元聚合的视角探究视频资源,尤其是影视资源在教学中的应用。研究从学习成绩、学习态度及课堂互动性三个方面对应用效果进行了检验。研究证明,深度聚合的视频资源在提高学习成绩、课程兴趣以及增加课堂互动性等方面有着显著的效果。With the application of information technology in education, video resources have been widely used in instruction. However, video resources are overwhelming in volume, are scattered all over the places, and are not effectively used. To overcome these problems, this study proposed a video aggregation model based on knowledge element, which is named as Knowledge Element - Video Resource Element - Video Resource Node - Video Resource Aggregation Network. This model has the advantage of enabling the video resources for /earning to have good ＂descriptive structure＂ and ＂organizational model＂. The model was applied in the teaching of Chinese Contemporary Literature course in a blended learning environment to explore the use of video resources, especially the film and television resources, in instruction from the perspective of knowledge element aggregation. Effects of the model were examined from three aspects： the learning outcome, the learning attitude, and the course interactivity. This study proved that deeply aggregated video resources could significantly improve students＇ learning outcome, their learning attitude, and the interaction in classroom.
