One of the first ideas I stumbled across online was Teaching Unplugged by Scott Thornbury and Luke Meddings. It made so much sense and despite having a department budget I decided to buy the book personally. It felt important for some reason and as I read it my lungs began to expand even further. The ideas these guys were expressing and quoting were like someone putting into words a fuzzy feeling you had from time to time after a class had gone well or when you'd taught a lesson without a brick load of photocopying.
The students asking the questions, relying on your interactions to direct the class, content being decided by them, language emerging organically, providing a safe and rich space in which you and the students can play. It sounded amazing. But then on top of that there were pages and pages of ideas ready to go. What more could you ask for?
