Ah. My first hit with a suggestion from Google to look at Google scholar. The phrase power in the classroom also appears.
It appears that this has pulled a lot about classroom discipline, I might tweak it and toss in "knowledge authority" to my search. I lose the Google Scholar link but some of these look closer to what I am after. Even though it does not nudge me to look at Google Scholar, it does give the citation counts for some of the journal articles that pop up. Useful.
CSCL1 popped up also. It's a bit dated from what I can tell from the publications. Still worth keeping as a possible term for further searching.
I think I have another leads to follow and enough to start populating a mindmap or two.
