Oliver Blagden speaks with Tom Bennett: founder and director of ResearchED, and Independent Advisor for the Department for Education.  They review his latest books: 'Running the Room' and 'The Running the Room Companion' - essential additions to all educators' Teaching & Learning libraries.  Along the way they discuss some of the challenges and misconceptions around behaviour, some solutions, and why it is that they can't get enough of 'Mary Poppins Returns.'
