开放教育资源的兴起与发展使得人们能够平等地获取优质教育资源，帮助每个人提升知识技能和改变世界。从麻省理工学院的开放课件到以Coursera、edx和Udacity为代表的大规模网络开放课程，人们对开放课程需求量越来越大，开放课程为终身学习和个性化自主学习提供了渠道。 本研究首先通过文献研究法对国内开放课程研究现状进行分析说明。然后，以案例研究和对比分析为主要方法，对国内外比较典型的开放课程从平台交互功能建设和课程学习过程进行对比，分析三个开放课程（国家精品课程、MIT OCW、Coursera）的教学交互种类、特征和层次，提出：开放课程的教学交互建设需要秉持开放教育资源的理念；注重远程学习者的特点来设计平台，开发交互性和过程性的教学资源；为远程学习者提供更多的交互支持服务，提供线下小组交流空间和社会性软件的支持；加强平台中教与学的相互作用，构建基于教与学的课程平台。

In this paper, at first, through literature methodology, to describe and analyze the study status of domestic open courses. Then by using the case study and comparative analysis as the main method, and contrasting the domestic and foreign open courses at two sides, the interactive features of the platform and curriculum learning process. To analyze the type, feature and level of the interaction, and find out that the teaching interaction construction of open courses platform need to uphold the idea of open educational resources.
