You may use telnet protocols to login to your school computer from home. Once connected, you can work in that computer just as if you had accessed it directly. There are various client programs available for telnet applications, as well. Some may already be installed on your host computer, and others are available for free downloading on the Internet. In addition to scholarly conferences and meetings in MOOs, many teachers meet with students online.
Discussions can range from informal classroom discussions to very formal presentations.
Many MOOs also have programmed files and tutorials on virtual television sets, slide projectors, or note objects. Although there is an abundance of information available in these sites, it can take quite a bit of detective work, and practice, before you learn your way around the cyber-terrain. And, of course, you should ask permission before logging or quoting conversations, and you should make sure you accurately cite your sources.
