What are the advantages of each class format?
The advantage of live-taped format courses is that you have an on-campus cadre of classmates and that your professor has a larger number of students to whom s/he is teaching the material at that time. The advantages to the pre-taped format are that they can (a) be taken during summer semester, (b) be completed (to some extent) in a compressed time for faster progress towards the degree, (c) be offered during semesters when live-taped versions would not otherwise be available, and (d) potentially provide access to courses which are not otherwise offered to distance students.
