I have been guided to a page about "Impact"

http://www.hefce.ac.uk/research/ref/pubs/2011/01_11/

so may follow better some of the views from CMS7.

Meanwhile there is news from South Korea. They plan to replace print in schools by 2015.

I can't find the research this is based on. But the government there has a record of reaching targets pretty much on schedule.

The UK HE debate around e-learning seems to me to be mostly about the difficulties, the association with managerialism and demands of quality procedures etc.

I will try to find the forms of "impact" from UK research but as an event the Korean decision is clear enough to make some comparisons about time lines.
