I am becoming a follower of the learning by doing approach. In a past life, I believed I learned best by reading and reflecting. If I wanted to see a practical example, I would try it in practice at work (or more realistically, I'd inflict it on my staff), or I would seek out an example sourced from an internet search. It never occurred to me to ask my teachers for a case study or an example - as far as I can remember anyway. I always thought that it was my job to work out how to use the process.
