From Graham Attwell's Wales-Wide Web a link to a newish report on students experience of blended learning from the Higher Education Academy. Unfortunately in between when I first looked a few days ago and now the report itself seems to have disappeared. Hmm. This is not good because it was a pretty useful report and a nice addition to the work of Karen Vignare and others who have done lit reviews on blended (or hybrid) learning for the Sloan-C consortium.
I have a copy, so if you're desperate I can read it out loud to you over the phone maybe. All 100 or so pages of it.
They limit themselves to reviewing UK and Australian literature (which is ok so long as you supplement your knowledge by reading Vignare's and Chuck Dziuban's reviews). The research team led by Rhona Sharpe also did visits to institutions who had implemented blended learning programs. One of the items that they deliver in the report is a list of success factors for blended programs (eg calling it blended learning which is a widely accepted term and the vagueness of the term allows your institution to define it in their own ineffable way).
