I thought that your inventory was comprehensive and thoughtful.I also agree that the design and course support are vital.
I liked the way that you would bring aspects of previous designs that had worked well into the new design and the way you would anticipate the demands on time and resource with respect to the response to diversity, but can one assess how much extra resource or time can be allowed for diversity,or is it a 'business plan' issue which has commercial limitation perhaps?
I thought that it was interesting that you recommended at least two Tutors and perhaps technical and admin support plus other support as necessary.Do you feel that more support is needed for online students ( Excluding the technical side}.
How would you ensure that all of the students on a forum or webinar were engaging? This is something that we are wrestling with at the moment because we have up to 20% who are not engaging on our new online courses.I felt better about it when I read about why students dropped out from an American Online University and what the levels of non engagement were.( Fetzner 2013).
Student retention is close to our hearts!
