I have always been told/been of the understanding (but I am not a teacher or even in the same area) that you should not praise children in terms of how clever they are but should praise children in terms of effort e.g. I can see you worked hard on that etc.
I have just been looking at my DC's books at a recent school event and noticed that my DC's teacher (KS1) sometimes comments e.g. Clever Boy/Girl on their work.
Is this still seen as something people should not do, or has the research moved on/I am mistaken?
