All of the 16 faculty members of the Department of Teaching Japanese as a Second Language (TJSL) joined in ""Virtual University"" (VU) project and developed 18 VOD (Video on Demand) materials named ""Invitation to TJSL Research"" about 30-40 minutes long each. They were applied in the ""Network Class"" using ""Quiz"" and ""Bulletin Board"" functions of WebCT to compare the conventional class. The students' evaluation showed that they almost equally favored both classes. The result suggests that the developed materials are effective and they are useful to discuss what to do and what could be problems for the future. The activities in the project and other problems related to VU matters are also discussed.
