This detailed book is full of fascinating thoughts and evidence about dialogic teaching, and is an inspiring and useful reference text for Oracy leads who want to delve deeply.
I particularly like the handy (and very convincing) list of eight justifications for prioritising Talk which you could use in discussions with colleagues, school leaders, governors etc. (p130).
