Hi, It's the summer! Normally at this point I like to dive into a good book but I actually thought it would be constructive to read one about teaching. All of my current teaching books are aimed at student teachers, I want to advance in my teaching techniques and wondered if anyone could recommend some good constructive books? I've heard about the lazy teachers handbook but heard it's mainly aimed at primary school teachers. Currently I teach a practical subject in a secondary academy. Any suggestions would be great!
