Abstract: We have conducted remote-collaborative lessons between Japanese and Chinese which maximize the language learning environment using the network. In these lessons, students make use of their native language to assist their counterparts in their learning, conduct discussions among themselves, as well as one-to-one communication practices. Features of the lessons include getting students to lead the conversations, and through sharing the experience, making them learn about each other’s language. For four years from 2007 to 2010, we have connected Japanese major students in Taiwan universities with Chinese major students in Japanese universities via the network, organized remote-collaborative lessons, and conducted discussions and language activities using a common curriculum. This paper reports on the activities carried out from 2007 to 2009, results which compared evaluations based on the ARCS model and results of the lesson surveys.
