We discuss the moral imperative for inclusion, how all teachers want to include everyone, the limitations of seating plans, coloured paper and fidget spinners. How it's all about curriculum, role models and language - looking at you, Paxman. We critique one-size-fits-all lesson planning templates and wonder if pair programming is working or masking the problem. 50 minutes of expert chat with an EdD and former HMI.
