> Teachers have to perform in front of a tough crowd. Certainly true. OTOH, there's hardly anything worse than a teacher with Dunning-Krunger syndrome when it comes to conveying the essentials of low-level programming to newcomers, so I would say that such a reaction is justifiable to a certain extent (as long as the tone wasn't too aggressive). Of course, it doesn't necessarily have to be the teacher's problem. I remember my first programming teacher in high school explaining in the very first lesson that honestly, he didn't have much programming experience (being a math professor) and had just dabbled a bit with pascal, but [sic] "the administration desperately were looking for someone to teach this course" and he didn't really have a say in it.
