【摘要】：目前国内外关于视频搜索的研究很多,但均不能很好地满足学习者特别是师范生的教学能力学习的需求,存在信息过载和聚合偏离等问题。如果通过领域分析和垂直搜索结合的模式,使搜索引擎能根据视频的内容和学习者提交问题的相关度对检索结果进行分析,将对提高师范生的教学能力具有针对性的帮助。本文通过对视频搜索引擎和学习环境的分析,在视频搜索的基础上构建网络学习环境,有效地提高师范生的教学能力,并对师范生教学能力的绩效提高提供了支持。基于视频搜索引擎的网络学习环境是对一般学习环境的个性化学习需求的专家层拓展,针对特定的师范生接受者群体,遵循建构主义的学习理念,突出了对师范生个人教学能力专项学习需要的满足,有效加强和缩短了未来教师的职前教学实践能力的培养过程。
[Abstract]:At present, there are a lot of researches on video search at home and abroad, but they can not meet the needs of learners, especially normal students, and there are some problems such as information overload and aggregation deviation. If the search engine can analyze the retrieval results according to the relevance of the video content and the questions submitted by the learners through the combination of domain analysis and vertical search, it will be helpful to improve the teaching ability of normal school students. Based on the analysis of video search engine and learning environment, this paper constructs a network learning environment on the basis of video search, which can effectively improve the teaching ability of normal school students and provide support for the performance improvement of normal school students' teaching ability. The network learning environment based on the video search engine is an expert layer expansion of the individual learning needs of the general learning environment. It highlights the special learning needs of teachers' individual teaching ability and effectively strengthens and shortens the training process of teachers' pre-service teaching practice ability in the future.
