Network-based learning or e-Learning has been taking an important role in education as helpful education tools. However, it is difficult for teachers to retrieve education data from students or to obtain data from the student activities. Therefore, we have developed a problem solving environment (PSE) for the education and learning support: TSUNATASTE.[1] The TSUNA-TASTE system collects the system-usage situation, the information for the windows used and the operation situation of the mouse and key board of all students. The data, which the system TSUNA-TASTE collects, are stored in a database on the TSUNA-TASTE system server. In this paper we present the structure of the TSUNA-TASTE system and detail structure of the network in the TSUNA-TASTE. The TSUNA-TASTE supports teachers and students in computer-based education. The TSUNA-TASTE may open a new helpful e-Learning world.
