The document discusses using web conferencing in the classroom and provides examples of its uses. Web conferencing allows live connections between people in different locations using video and communication technologies. It can be used for point-to-point calls between two classes or groups, multi-point conferences with many participants connecting to a bridge, and webcasting where one group broadcasts to others. Examples provided include connecting with classes in other states or countries, participating in virtual field trips to zoos and museums, and collaborating on projects across distances.
