I doubt it very much. Children have an amazing capacity to learn and are usually constrained by adults thinking that kids can't cope with more than simple challenges.
Some of those are even to hard for some adults I teach to. One of the most important thing in pedagogy is to never mix several notions in the same theme. E.G: making exercices involving maths.
absolutely. if maths, etc had have been framed like this I would have been a model student. as it was, I spent my time coding other (not useful) things instead of homework
