Mapping OER impact

So today we had one of our 'sprints' on the OER Research Hub. We have developed a cool impact map for plotting evidence from OER Research against our 11 hypotheses. Martin Hawksey did the development and it has lots of nice features, including Sankey diagrams and heat maps and summary pages. This week we are trying to aggregate all the evidence we can find from other work onto the map. There is surprisingly little actual research about OERS. Lots of projects saying that they have released them, lots of beliefs about how they have the potential to change things, but not much hard evidence of them doing things like improving performance.
