Michael I looooove the questions of power you are asking. I must be really behind on reading ur blog – are those your areas of inquiry these days?
But so let me share a quick experience about making power issues explicit to students. I have done it with student-teachers and despite initial resistance it worked really well to make them more conscious of these things and start doing it themselves. I haven’t imagined what it might mean to do it for k-12 but today i read a blog post by @bluecerealeduc talking about discussions of race and other injustice in the classroom. I really feel learners need to be able to connect how macro power issues like race manifest themselves in their microworld whether classroom or social. If there is a hangout discussion about this someday i would definitely like to watch it!
