The potential for on-line corpus in language teaching and learning has been the focus of attention on the part of teachers and researchers for some time now. The purpose of this study is to report on an Internet-based concordance approach to language learning and to investigate both qualitatively and quantitatively Taiwanese English-as-a-Foreign-Language (EFL) students' attitudes toward this learning tool. A 3-week, on-line corpus lesson was designed and implemented with a sample of 37 college students at a Taiwanese university. A questionnaire survey was then administered to investigate student's feedback on the Web-based concordance. The results of the study indicate that students in the study tended to have positive attitudes toward the use of the Internet in education. The challenges and possibilities for integrating Web-based material into the EFL classroom are also discussed. Images of the Web-based material are captured in images of a computer screen running the Chinese version of Microsoft Explorer with EFL material on display. Several tables display quantitative, statistical data. It is concluded that the Internet simply offers too much potentially useful and authentic spoken English for any EFL teacher to ignore.
