I liked the instructor I had for my 101 class and really didn't enjoy the discussions at all. So much of what people raised didn't engage with the material, questions that were straightforward to address, or simple clarifications (that they asked as 'gotchas' more than out of confusion).

I think it's unfortunate that so much of the pedagogy is focused on following the history. Of course it's useful for people that plan on continuing with it, but it's a terrible introduction.
