Talking to Imogen for the new podcast has made me think back to when I started. I remember very well how I was only a few years older than the kids I was teaching, and my knowledge was only marginally ahead of theirs. I have wondered over the years whether my knowledge has moved on much beyond A Level. I am certainly much more experienced than the kids are and can get to a right answer faster than them, but not being a Physics graduate still leaves me feeling exposed at times.
There are so many things you need to be a successful teacher over and above a Physics degree that I don’t fret too much. Loving the subject and still finding wonder in it (whilst teaching essentially the same content each year) goes a long way.
