Faith , It depends on the instructor and the content. Unfortunately, I have seem some instructors remove most of the interactive components from larger courses because they do not have the time to properly respond. This would also reduce the effectiveness of most online courses (which is what I believe you would find in the literature). The key to online environments is to build a sense of community in your courses with instructor to students interaction and student to student interactions. You can do more peer reviews and student driven interactions to help facilitate larger classes as well. Herbert Brown III
