Abstract: Influenced by Web 2.0 and cloud computing,online education platforms based on Web browser develop rapidly and have great impact on remote education,in-class teaching and collaborative learning.However,most of current education platforms seldom focus on synchronized education based on Web graphics,which is very important for process displaying and learning interaction on teaching materials.We firstly analyzed three major application fields of current online education,and then put forward an online synchronized education method based on graphical Web operation record and replay.On the one hand,the method supports basic synchronized education by high-fidelity operation record on presenter’s terminal and self-adapting operation replay on audience’s terminal.On the other hand,it also ensures reliable and orderly online education for both normal participants and late-comers by interactive synchronization control.Based on the method,we implemented Smart SEP (Smart Synchronized Education Platform) and gave detailed case study,which performs synchronized,dynamic and interactive education and verifies the feasibility of our method.
