hi Gillian, Kae and all,
Great thoughts, and I agree with you that the reason most of us teach or train is to get people more skilled or knowledgeable, or to increase their performance (so they can have more spare time, yes, that would be why I would increase performance :-)
But in order to achieve this, I think learning analytics should be followed in the long-term. I do not think short-term analytics are capable of directing instructors or trainers towards an improved scaffolding or learning-support position that really makes a difference. There are too many factors involved in learning/teaching, which is why I think only a long-term analysis can result in 'best practices' for learners and teachers. Short-term analytics can help with situating learners that are in need for extra support, but not on how the whole group could benefit.
