Erica,
Actually many faculty find the reverse. Online when done right includes all forms of delivery and interaction, including lecture components if appropriate. However, much of the class interaction is asynchronous. I can promise you that you can talk MUCH faster than you can type, so you are at a distinct disadvantage when communicating online with all of the discussion forums to respond to, emails to write, etc. It takes a lot of time to provide sufficient interaction with your students so they feel they are part of a course.
