David has been involved in mathematics education for most of his career and has taught mathematics from reception to university degree level.
He is director of the Centre for Innovation in Mathematics Teaching (CIMT) at the University of Plymouth. David has directed three longitudinal international projects in comparative mathematics education in primary, secondary and teacher training. These involved working with countries such as Finland, Hungary, Russia, China, Japan, Singapore and New Zealand.
Each of these projects has led to reports with detailed recommendations for good practice in mathematics teaching and training as well as curriculum development. Recently he worked as the teaching and learning expert for the Core Maths Support Project.
David recognises the potential of lesson study combined with interesting and relevant problems as a starting point to motivate and re-energize teachers and learners for new mathematical topics.
