Old-school (online) trainers will be familiar with the 4 Level Kirkpatrick evaluation model. I have occasionally used in HE to look at online and classroom-based training. This is a substantial revision which starts with defining what the results should be and then goes backwards through the four levels in sequence, building a “chain of evidence” with data from all four of the levels. Could be useful when looking at the impact of screencasts, for example, with a view to estimating what Kirkpatrick calls this Return on Expectations, or ROE (nice term!).
