When I think about Open Education I am not so much concerned with the whys but more with the hows and the outcomes. So for me as a teacher and as a student the most important part of it is being able to choose instead of having my education spoonfed to me by the institution. I am sure that choice is a great part of the reason only about 15% of the students who enroll in a course finish. Maybe they didn’t find exactly what they wanted. Or maybe they didn’t have the time to complete the course at the time. But the important thing is that they have the choice to take the course–even again and again if they wish, until they achieve the learning outcome that they want.
