I have a PhD in maths and am currently doing my teacher training. My PhD has been fuck all use so far. I’m really good at maths. It’s always come naturally to me. That does not in any way help me explain it to kids who struggle with maths because they just don’t see it the same way as me. I know the syllabus extremely well, I could easily get a grade 9 if I sat the GCSE exam now, it does not make me a good teacher.
My mentor on the other hand actually trained as a primary teacher originally, is not a maths specialist, and only teaches the foundation syllabus because she’s not confident with the material on the higher syllabus. She is a fantastic maths teacher and I’ve learned so much from her.
If you’ve been to university surely you know that having a PhD doesn’t make you a good teacher. There are lots of lecturers who are really well respected in their field of research who still manage to be rubbish at teaching.
You don’t need a PGCE to teach in UK state secondary schools though, you only need QTS. You also don’t need QTS to teach in further education. I taught a GCSE resit class to post 16s for a few years without being qualified. There are a few different routes to get that. If your friend is serious about wanting to teach, googling “get into teaching” will bring up details of how to go about it and who to phone for advice.
Assuming that a PhD should be enough to get a job as a teacher is very naive. Teaching is a very challenging skill to master, and one that is not really connected to academic ability. I thought a PhD in the subject I want to teach, plus seven years teaching experience prior to starting my training, would make it fairly easy for me. It’s been quite a shock discovering how little I know. If you want to be a good teacher, regardless of how good your academic qualifications are, you have to leave your ego at the door.
