Charles Lovitt, a distinguished designer whose outstanding contributions to mathematics education are characterised by their combination of depth and breadth. His work on the design and development of innovative materials for teaching and professional development has had a profound impact on the teaching and learning of mathematics in Australia and beyond. Charles lives in Melbourne, Australia, but over his long career has worked with teachers around the world.
Derek Holton trained as a secondary teacher but has spent most of his life as an academic, doing research in combinatorics and various aspects of mathematics education, including problem solving. However, he has never lost his interest in trying to show students what he enjoys about mathematics. For almost 25 years he worked in New Zealand, where he was part of the group that prepared students to take part in the International Mathematical Olympiad. An Honorary Professor at the Melbourne Graduate School of Education, Derek is now retired but still works with students and teachers at every opportunity.
