To compensate the lack of awareness in CSCL environment, a CSCL chat tool capable of displaying all the participants’ key typing process was developed. The system displays key by key typed in letters to other learners. The smooth turn-taking and topic negotiation is expected by the realization of real time display. From our preliminary evaluation, learners evaluated the conversation using this system easier, even though number of sentences between the proposed system and the usual chat system was not significantly different. Learners’ comments after the usage shows that there are both merit and demerit of the system such as natural awareness and neglecting of writing complete sentences. In addition, tools such as showing dialog transition among participants/learners and typing speed calculation were developed for further analysis.
