Dale Sidebottom is SO not your average gym teacher. He explains how his unusual name forced him to come up with games when he was a substitute teacher (called 'supply teacher' in England and Australia, where he has taught). He has created 35 apps, run workshops for professional development through his company "Energetic Education" - all while teaching full time. Now he travels the world running teacher workshops. You'll be inspired (and tired) just listening to him. He is also the first elite cricketer we have had on the podcast.
