I am not aware of anything that directly responds to your question. Nonetheless, there are a couple of work I have come across which explores gthe bakhtinian argument and have sought to relate then to educational concepts which I think you might find useful.. See titles and links below:

In Theory Bakhtin: Dialogism, Polyphony and Hroglossia

 https://ceasefiremagazine.co.uk/in-theory-bakhtin-1/

This particular work explores Bakhtin and connectedness, which in my view is very useful for self study.

The other piece of work is 

Wegerif, R (2008) Dialogic or Dialectic? The significance of ontological

assumptions in research on Educational Dialogue. British Educational Research

Journal 34(3), 347-361.]   The link below

Just to add to Gordon's suggestions, Robin Alexander has written several great essays developing his notion of dialogic teaching influenced by Bakhtin in this collection:

Hello Bridgette,

The following link could be useful for your interest. Rupert Wegerif has worked  a lot with dialogic education:
