I can now appreciate how, for many learners, an online (or correspondence) course can provide an enhanced learning experience with better learning retention compared to a traditional in-person course. This amazing result is possible because an online course can provide and integrate a variety of methods to engage the student - video, audio, chat, discussion boards, knowledge checks, and so on. By varying the way that content is delivered and discussed, the instructor--through an online course--can reach the varied learning styles of students.
