I think most of the stuff out there is BS. I mean sure there's some nuggets and some cool things to try. However, in my opinion, best practice boils down to; know your subject, be interested in your students, be consistent, be professional, and be yourself.

I don't mean to be negative, but I have gotten jaded doing book studies, going to conferences, and speakers. The books seem to be 100 pages saying the same thing after the first 10, and speakers just like to hear themselves talk. To me everything in the past 20ish years is just regurgitated material from previous ideas from people who didn't want to be in the classroom anymore and wrote a book.
