Hi sightlight In the 1970's many kids learnt programming from typing in games from magazines, then debugging. R-pi will be used in places where the teaching is zilch, the net is down or hasn't reached, and an able youngster has cobbled a system together, or perhaps in a hole in the wall situation, no guidance but a group of determined youngsters. Here small printouts of code for entering and exploring might help. Not sure one language would cover it.
Hi tnelsond Agreed, thanks. For the guided world I'd love to see a longer list, perhaps flagged with languages and degree of difficulty. Mine was just a starter.
