Not new at all... There's a huge amount of new stuff for beginners to
learn, so they need simplified ideas to get them started. But it
shouldn't ever have to be about unlearning. We shouldn't be feeding them
false ideas that they will need to throw away completely.

Our local radio club does a lot of teaching, and at all levels we try to
say: "Learn this to check the right box in the exam, but remember
something else about it: it isn't a hard fact. It's actually an onion."

At the next level, we peel away a few more of the skins. The aim is
always to show them how last year's simplified information fits into a
bigger and deeper picture. We don't want them to throw the old
information away; at the next level we want them to keep it, understand
what was right about it, and also see its limitations.

At least, that's what we are aiming for. The challenge for the teacher
to live up to it.
