In this episode, the first of a new season, we look at a group of thinkers who have focused on how we should evaluate the impact of the learning. Beginning with Donald L Kirkpatrick in the 1950s, they have given us models of how to measure and evaluate it. However, for all the work that has gone into this area, the general perception has long been that organisations simply do not evaluate anything like enough. There are indications, however, that this picture is changing, and interest in evaluation is on the up. With the advent of powerful new AI tools, could we be on the brink of a breakthrough?
