This paper describes a prototype and its experimental evaluation of the chat system that offers cooperation support between discussion space and activity space in collaborative learning. In collaborative learning in the proposed system, students are divided into groups, carry out discussion on a study theme by chats, and create on-line reports in cooperative manner. The proposed cooperation support method aims at improving the level of cooperation among students and the effectiveness of the study by making group members grasp other member's study situation mutually through cooperation support in group member's utterance and report creation. We use Wiki as a tool for collaborative work in this research. Cooperation support displays the Wiki's updating time and contents on the chat system with activity cooperation support that offers a space for remote collaborative learning and allows a student to know about other students' condition. In addition, the number of chat utterances was displayed, and other students' condition is easily grasped.
