# Professor John H Mason

Having taught mathematics ever since he was 15, John Mason was retired as Professor Emeritus from the Open University in 2009 where he had worked for 39.5 years. He continues an active interest in and concern for the teaching of mathematics in schools in each and every phase, from kindergarten to university.

He conducts numerous workshops for teachers in the UK and abroad, leads seminars, and presents plenary lectures, always stressing the dimension of lived-experience rather than theoretical stance.

**Research**

His principal focus is thinking about mathematical problems, and supporting others who wish to foster and sustain their own thinking and the thinking of others. Other interests include the study of how authors have expressed to students their awareness of generality, especially in textbooks on the boundary between arithmetic and algebra, and ways of working on and with mental imagery in teaching mathematics.

He is perhaps best known for being the principal author of Thinking Mathematically (with a new augmented edition published in 2009), joint author of Mathematics as a Constructive Enterprise: learner generated examples with his wife, Prof. Anne Watson, for his uncompromisingly experiential stance to research methods in Researching Your Own Practice Using the Discipline of Noticing and for his contribution to practical suggestions for teachers such as Questions & Prompts for Mathematical Thinking, and Thinkers, both written with colleagues.

**Research Topics**

- The role and structure of attention and intention in teaching,learning and doing mathematics;
- The Expression of Generality in Mathematics Textbooks
- The Design and Use of Pedagogically Effective Tasks for Mathematics Learning
- The Design and Use of Applets for plenary use in teaching mathematics
