Videoconferencing: This is communicating via a live video link over the Internet. Conferencing and telephony applications usually cost no more to use than a local phone call, whether you are speaking to someone across town or on the other side of the world. However, they require a very fast, stable connection to the Net, special software; and of course, a video camera, microphone and speakers. Teachers have been making active use of this technology for several years now, especially in distance education and cross-curricular project work.
