Interactive video in training

It doesn't take an expert to work out that interactivity is the key to good training. From the nursery school child on the teacher's knee to the university tutorial, people learn best when they're involved, talking, reacting, DOING something. That might seem to be an argument against distance learning; but distance learning is often the most convenient, cost‐effective way of providing for a training need. And interactive video — good, well designed interactive video — can provide uniform and efficient individual training which involves every student, every inch of the way.
