Teachers will tell you never to take away teaching time, that they are hard pressed to deliver all the required course work as it is. If you want to involved 'Technology Enhanced Learning' (TEL) that it needs to during added hours.
The OU has taken up with Google's philosophy of more 'facilitator-led learning' with those teachers who create the courses elevated in status, while everyone else takes on what they may see as a diminished role. Or an apprenticeship role before they too become writers of content.
I am putting it too crudely. Teachers do hours of planning to carry the hours of 'taught hours' that they deliver. If they are able to teach may more by including the indirect experience of learning online then this may, in some measure, begin to cater for the millions around the world who want a secondary or tertiary education but don't have access to one.
