4. Discussion and conclusion
Our in-class chat system had several advantages over related approaches. Compared to an environment like DIWE, our text chat offered a major advantage because it could be accessed through a web browser without requiring installation. This significantly reduced the difficulties of managing the software, and given the speed and convenience, the Internet browser would be sufficient for practically every educational delivery method in the near future. Twenty-nine students were able to connect with their own notebook computers to participate in interactive writing sessions. As the chat updated automatically, there was no need to reload, and the writing could be submitted much more like a face-to-face conversation than a forum exchange. The instructor took the role of a writing companion, guiding students through exercises. One disadvantage of our in-class chatsystem wasthat the instructor needed to lead the class actively, which did not allow a lot of time for visits with individual students, a reported advantage of DIWE (Chávez, 1997). We overcame this disadvantage by having two experienced EFL teachers teach the course, allowing one teacher to lead the class while the other took care of other responsibilities.
