Ouch, that disparaging attitude towards teachers and what they do is exactly the kind of thing I am talking about. I assure you that my negative attitude towards almost all of education research I read is based not on taking the easy way out or being anti-intellectual. It is instead because I am appalled by the poor measures that the researchers use in their attempts to emulate scientific method, proceeding as if students were laboratory rats, and their focus on decontextualized variables while using grades and standardized test scores as meaningful outcome measures, etc.

And just as you contend that teachers lack a knowledge of research, I would contend that a lot of researchers have limited experience with teaching, and their limited experience badly undermines their research design.
