As Honorary Fellow John attends seminars and consults with current staff in Mathematics Education.

During 40 years at the Open University supporting the teaching of mathematics he authored a wide range of papers, and dozens of Open University Books and Teaching materials. He co-authored the classic Thinking Mathematically; Mathematics as a Constructive Activity (with his wife Prof. Anne Watson); Questions and Prompts for Mathematical Thinking & Thinkers (with Anne and other colleagues), among many others.

His research methods are phenomenological, based on the Discipline of Noticing. He is interested in the lived experience of learning, doing and teaching mathematics. He focuses on the structure and form of Attention in the teaching of mathematics, as he supports those who wish to foster and sustain mathematical thinking in others.

He is an Honorary Fellow of BSRLM and ATM, a long-standing member of  the MAA and the  MA.H.
