The research mathematician and his A level teacher

GCSE maths teachers will recognise the profile of the disengaged 15-year-old that understands maths easily but hasn’t the motivation to put in the work for a really good grade. This student will often drop maths post-16, or if they don’t, you might lose sight of them as they go to college or join another teacher’s A level group.

If you have seen a few of these characters through your doors, you may be encouraged to hear this conversation between Douglas Coates, now a research mathematician at Université Paris Saclay, and his A level teacher, Tom Rainbow. Doug explains how maths came alive for him post-16, and what it was that inspired him. And he poses a great little maths problem (from John Mason) for you and your students to try!
