Educators spend lots of time trying to keep classrooms in order and answering questions that only one person is interested in (remember that one guys who always asked the weirdest questions in class?). A lot of times, a teacher can spend 80% of class time explaining 50% of the content. What if all this time can be condensed into a carefully-outlined pre-recorded course?
While the course material can confuse students who often need a bit of hand-holding to get things done, you’ll notice that they’ll get along better as they repeat recorded courses. Either way, teachers will still be around to answer questions during virtual office hours. The difference here is that the questions will no longer take up course time.
In fact, something you can do to make this easier for both students and educators is to set up a forum or FAQ. If multiple students have the same question, they can see that the question has already been answered at one point and continue the learning process without much interruption!
