I am skeptical that distance education based on asynchronous Internet technologies (i.e., prerecorded video, online forums, and email) is a substitute for live classroom discussion and other on-campus interaction. Distance education students can't raise their hands to ask instructors questions or participate in discussions, and it's difficult or impossible for them to take advantage of faculty office hours. Teaching assistants don't always respond to email, and online class discussion boards can be neglected by students and faculty alike. In this sense, the "process of dialogue" is actually limited by technology.
