The present work deals with the notion of the Internet as a teaching medium, describing extensively various aspects of the teachinig process, such as available Internet-based activity formats (chapter 1), tools for possible use in an Internet classroom (chatpers 2 and 3) and Internetassisted language skills instruction (chapter 4). The issue of designing Internet-based language teaching, both on the level of an individual lesson and the overall curriculum, is addressed in chapter 5, while chapter 6 contains a discussion of practical aspects of organising, managing and troubleshooting an Internet-based classroom.
