I like use the analogy of serving up food to students as a way of describing teaching and learning. Imagine serving up scrambled eggs on toast every day to students. Ok, so some variation is needed so I add a bit of bacon or tomato or cheese (they like cheese!) to vary the menu. I think kids would eventually get tired of the same old food. Some may even refuse to eat it. Sure we can starve them but that won't change the basic pedagogy.

Then the realisation hits… why don’t we let the kids design their own menus and eat their own food, or even share it around. That would make food much more interesting and engaging. I’m sure the kids could teach me a thing or two about food but I would still have to direct them. We can't eat steak all the time - there are constraints, but it would be much better than eggs on toast every day.
