Hi Zhihao Wang,
I feel so impressed when I read your blog 1 about Multimedia and interactive learning. You shared an informative video to explain its concept and application. I totally agree with you that online teaching with multimedia tools can improve our learning environment. Like the blog we are using now, we can easily get access to it and mark down the keynotes. Classmates can leave their positive comments and feedback to improve our learning efficiency. However, online multimedia learning has its disadvantages. When we are learning in the traditional class, teachers can have more interactive teaching methods, such as think-pair-share and buzz session. Teachers can participate into their discussion and give immediate feedback and instruction. However, in online courses, we cannot even know what our classmates look like, which, more or less, decreases our interests in group discussion.
