I, as a teacher, have had to learn several languages, but that's not the dumb reason bit. The dumb reason bit was WHY I had to teach Python, which once I learnt it (so I cold teach it) I could see right away was NOT a suitable language for teaching to Year 7 (who up to now have only used Scratch). I was teaching the U.K. curriculum, and I found out that teaching C# was also allowed - still not ideal, but better than Python for learners -but pretty much all schools were teaching Python. When I dug into it I found I was far from alone in not wanting to use Python... and I also found out the reason schools were teaching Python. It was because from an ADMINISTRATIVE point of view it was much easier for the schools to have us teaching Python. In other words, the office-workers who didn't have to teach it, only had to admin it, were forcing everyone to teach Python because they wanted the lower overhead that came with installing/maintaining that vs. C#. ARGH! All the teachers who wanted to teach C# were running into exactly the same road-block.
