The responsibilities are the same. The instructor is responsible for teaching, and the students are responsible for learning. However, the differences in the settings create great differences in the interactions that occur for a great teaching/learning environment. The participants in online education do not benefit from face-to-face communication, which often permits quicker communication of course objectives, policies, and practices. Instead, the communication depends mostly on written communication through posted information, email, and discussions. Resolution of communications issues may be more difficult, and in some cases, communications issues may not be apparent or resolvable in the online environment.
