Looks to be a lot of opinions here (~3,800 hits).
There is a post about 'web traffic control'. Might be a handy lead into my paper. It is in the ban it category which has a long history in schooling.
There is another angle here about the privacy of teachers, i.e. access by students to tachers' private online activity. Hmmmm
There is also a good deal about discipline, i.e. student misbehaviour and the role of social media. Important but not where I want to go.
Ah. But here is a good find. Notes on Critical Teaching & Everyday Life by Ira Shor. Quoting from the book:
he defines the classroom “as a place where knowledge, perception, ideology, and socialization are challenged.."
This might be a way in. I know there is a large literature about developing critical capacities in most/all? of the fields of knowledge taught in schools. I don't want to revisit the silly digital literacy stuff but to find material that goes to the role of the teacher as an experienced player in the field. Not just a conduit, which is what the Internet does now.
I might have a look at Google scholar now to see what is there about the C word and these other terms I have been playing with.
