Tandem language learning occurs when two learners of different native languages work together to help each other learn the other language. First used in face-to-face contexts, Tandem is now increasingly being used by language-learning partners located in different countries who are linked via various forms of electronic communication, a context that has become known as eTandem. In addition to providing a brief account of the history of Tandem and eTandem, this paper provides a comprehensive overview of electronic communication media suitable for eTandem, both asynchronous and synchronous, from the telephone and email to amateur radio and business-quality videoconferencing. Finally, the Electronic Network for Language And Culture Exchange (ENLACE) is introduced, a Web-based medium through which users of Windows, Macintosh, and Unix-based computers can find language learning partners and engage in eTandem language learning using synchronous text chat alone or in combination with video and/or audio conferencing.
