Research on learning support system for improvement of CMC ability to develop interpersonal relationship

利用电子邮件、聊天、博客、社交网络服务（SNS）等进行的计算机媒介通信（CMC）正在增加。然而，以往的工作指出了CMC存在的各种问题。本研究认为，CMC既不能凭自己的风格，也不能凭经验，而是要有科学的依据来提高CMC的能力。然后，在本研究中，首先假设CMC的信息是由语言信息、准信息和非语言信息三种信息组成的。其次，本研究试图厘清言语者在电脑媒介人际交往中的印象变化。在此基础上，构建了培养CMC能力的学习支持系统。

Computer Mediated Communications (CMC) that use E-mail, the chat, the blog, and SNS (Social Networking Service), etc, have increased. However, the previous work points out that there are various problems in CMC. In this study, it was thought that CMC relied on neither one's own style nor rule of thumb but had to improve the ability of CMC based on scientific grounds. Then, in this study, first of all, the message of CMC was assumed as a composition of three kinds of information on a verbal-information, para-information, and non-verbal-information. Next, it tried to clarify the change in utterance person's impression in the interpersonal computer mediated communication. And, it aimed to construct the learning support system to develop CMC ability based on those grounds.
