We are trying to do away with some of the smoke and mirrors surrounding online distance learning. For example, you should avoid schools that are not accredited by a state board. Also avoid institutions that do not offer direct communications with teachers.
Much of the actual work involved in completion of your degree will be very much the same as in a traditional college or university. The Internet has not as of yet replaced good old reading and writing and communicating with teachers and other students. This remains the basis for a good education, and is the core of an online education.
Course materials are usually delivered in an online format, but occasionally paper texts are used too. Instructors will keep virtual "office hours" through a bulletin board service or an online discussion group where other students will be participating as well. There is also around the clock access to email which will be a vital tool in communicating not only with your teachers but also with fellow students.
Occasionally lectures are conducted via video conference as well as streaming audio. An important point to remember is that no special technology is needed. All you need is an Internet ready computer and an online connection.
