I think that the responsibilities differ in some ways for online and traditional classroom settings. I think in both, the instructors have a responsibility to be the best teacher they can be for their students. For a tradiational classroom, the instructor is required to physically be there and are able to really connect with the students one on one. For online, the instructor is required to always be avaialbe for the students because they are working around the students schedule which could be always at night, or always in the day. Regardless of when or where the class takes place, the instructor has a responsibility to be there to support and guide the students.
