Christine, I agree that the time commitments are different. I find I also need to be available for my traditional classes outside of normal class hours. Even though many students wait to ask questions in class, I still have to be available if they have questions on assignments, etc. Fundamentally are the responsibilities not the same: instruct the students, help them gain new knowledge, provide appropriate feedback on assignments that reinforce their learning....The way we do it might be a little different, the tools we use and even the need for more flexible communications....
