Jeong-Won Won and Ik-Hwan Kim. 2001. A Study on the Improvement of English Writing Ability Using the Internet. Studies in Modern Grammar 23, 165-188. The Multli-User Dimensions Object-Oriented(MOO) is a synchronous interacting program unlike other asynchronous programs such as e-mail, mailing lists, or Usenet. This study is an attempt to suggest ways of improving students` writing ability by exploring the Schmooze University, on of MOO sites for ESL or EFL English learners. Schmooze University offers language learners opportunities to communicate with native speakers and other English learners from all over the world. Through this system they are able to exchange on online their ideas about each other`s culture, customs, and about learning a language. This authentic, task-based learning environment creates a more attention-attracting and interesting learning situation for those learners of the English language.
