Great - hope you can accept Elixir if it ends up like that. (Ducking the stones!).

Experience is highly underrated these days, so thanks for contributing.

I totally agree with these points. In the dark ages I taught Java at the Technical
University of Denmark and I tried - intuitively - to incorporate all of the points
you mention. The course ratings went from 1.5 with the previous pedagogy heavy
oldster to 4.5 on a 5 point scale. I used real-world examples and games.
So I would say that these principles applies to all learners - regardless of age. As
adults many forget to have fun and continuously tickle the learning desire in us.

That is a very instructive story. I, for one, want to fight this.

At ESL we have worked with the R-Pi and created the Erlang/ALE library, but it has
been a bit slow after the main driver left the company :-(

It sort of reinforces my core belief that in the right wrapping kids can learn a lot
