I had a really authoritarian teacher that insisted to learn whatever I wanted and show 2 months later what I made. I learned iOS programming and sold an iphone app in that course and got a 90% grade. I had another really authoritarian teacher that insisted to follow the book by the letter. I got a 75% grade, I was sad I was aiming for 55% as a signal to say that he was a terrible authoritarian. Clearly authoritarian teachers should be the former, not the latter. However, some of my classmates begged to differ the exact opposite. Interestinglt enough, these are all true stories. I wish they were hypothetical.
