Who cares about course completion?

In his blog, Courses or Learning Episodes, Steve Wheeler, provided much food for thought. The instructional design course that I facilitate online does not have as a goal course completion by all students. The goal is simply to provide a source of just in time learning experiences presented in a context that encourages learners to recognize the importance of remaining conscious of overarching goals; goals that far transcend any specific subject.
An essential question is how do we design learning experiences with the ultimate goal of progressively requiring less and less directed learning or structure from course facilitators? I think most teachers enter the field with the goal of helping students to discover and strengthen their voice by encouraging them to exercise their voice. However, along the way that goal becomes greatly over shadowed as we attempt to adhere to program and course guidelines that unnaturally restrict learning experiences by discipline or subject as opposed to teaching holistically. Of course teaching holistically demands collaboration and transparency, 2 things that are often challenging to implement regardless of the learning environment.
I think conversations related to education reform efforts should be more about identifying and exploiting the unique value different learning environments provide which support the design of authentic learning experiences. Thankfully, the options for how we present lessons is virtually endless. However, if the students are not engaged and actively interacting with the course materials; they are just that: course materials. Learning can only be exhibited as a result of the interaction.
