"But incase you are interested. We have tests ever six weeks. I analyse the data and award levels. i measure percentage change, alalyse by topic area and target grade. Jesus - I have a 1st don't you know!" Clearly anyone with a modicum of mathematical ability and a little excel knowledge would be able to do this - with or without a maths degree of any class. I have to ask where you did your Maths degree. I didn't do any data analysis in mine, I can do it but my degree and class in it is irrelevant. This constant reference to your 1st is really showing up your insecurities. Did it occur to you that your HoD might be right about it taking time to master different teaching approaches?
