Medium means “middle” originally. When it is used as an academic term in communication theory, it would be a bridge of information exchange between two agents. The more advanced medium is, the richer amount of information it can carry. And then the communicating way changes. The way of thinking changes, too. This paper firstly analyzed the development of communication process and the corresponding changes in media, and then discussed the major impact on education re- form in different media. Each of the change will affect the media choice of teaching strategies and teaching effectiveness. Especially when the information media are used in education, much more information changing happens than ever before. People can learn with auditory, vision, tactus, olfaction, and so on. “Communication” became one of the most important keywords in the study sup- ported by information technology.
