As the theoretical basis of educational technology, communication is still in its infancy. At present, there are some problems in the research, such as being greatly influenced by related events, the research type being biased towards theoretical research, and the theory and practice not being effectively combined. Communication will have great development space in the following aspects. First of all, with various new concepts and new educational models such as mixed teaching environment, mobile learning and digital classroom flooding into the field of educational technology. Communication studies in the field of educational technology have ushered in a new opportunity. Exploring these concepts from the perspective of communication will effectively promote the development of these concepts in the practical application layer. However, the analysis of these information concepts from the perspective of communication in the existing literature is still in the initial stage or blank stage, which needs further exploration by researchers. Secondly, at present, the communication in the field of educational technology still lacks in-depth excavation of the laws of communication itself. The field of educational technology has strong application characteristics and needs targeted theory to guide it. Finally, in the current communication research, theoretical research and practical exploration are not well combined, which leads to the relatively slow generation and accumulation of communication theory and the difficulty in in-depth exploration of communication practice. Therefore, it is necessary to strengthen the combination of theory and practice, so that the exchange in the field of educational technology can enter the track of benign and rapid development. As a young research object, the related research on communication in traditional classroom teaching and distance teaching environment has achieved certain results. And it has unlimited development potential in a wider field. All kinds of people who have made unremitting exploration of communication in the field of educational technology, especially normal colleges, have an open and positive attitude towards communication research, which can effectively promote the development of communication research.
