The quality of written responses from students is imperative for them to attain the highest marks. Because of this, whilst they are working on a question, look over their shoulder, read what they are doing and then write a question on their work for them to respond to, to improve their work. Of course it’s not always possible or sensible, to do this with every point that you want to make for every student, but worth doing for big errors/gaps. And if it’s written down in their book, it’s a good reminder for them not to repeat the mistake next time.
