Nevertheless, it is an issuewhether the teacher can identify unique values of different EFLmethodologies and how appropriately and effectively the teachers applythem to their English classes. Moreover, with the development ofcomputer science, many EFL educators have produced a great deal ofinteresting and pedagogical software. However, it is an issue whetherteachers, who are life-long learners, have the ability to upgrade theirown teaching by means of computer media and software. Because thedevelopment of CAI tends to be multi-media-oriented, thedemonstration of EFL methodologies can be presented m'ulti-sensibly,eclectically and effectively with a multi-media computer system. In order to study the characteristics of different EFL methodologies, including their features, merits and limitations, to compare them, andto investigate the possibility of training EFL teachers by means of amulti-media computer system, some EFL methodologies, bothconventional and innovative, are collected and reviewed in this study.As well, a software program on the demonstration of EFL methodologies .is produced by a multi-media computer system. Specifically, the purposes of the study are to provide EFL teachers with
