classrooms on the web

People are in school for a variety of reasons: to learn a trade; to explore interests; to earn a credential; to discover something about themselves. And in many cases, a college environment is the best place to achieve these goals. But it may not be the only place.

The college classroom is more accessible today than ever before. And though just listening in on a couple of lectures is not a substitute for the college experience, you can gain exposure to issues, topics, and scholarship that once resided exclusively within the ivy tower.
