Online education plays a more and more important role in the era of Internet and cloud computing, but two problems remain unsolved including MOOCs. First, most of existing online education platforms only provide teaching materials in format of ppt, pdf, video, and they seldom support education based on graphical Web applications. Second, some online education platforms may provide self-governed chatting tools or whiteboards, but they are not combined with teaching materials closely. As a result, they cannot satisfy the need for the real-time interactions based on complex teaching materials. To solve the problems above, we put forward an online education approach using Web operation record and replay techniques, and implement online synchronized education and real-time interactions between teachers and students. Moreover, we develop a supporting tool OSEP for the approach. In the case study, we describe three education scenarios, which verify that the approach supports not only personal learning by tutorials and wizards, but also online in-class real-time collaborative learning.
