Before joining CUHK, Dr Chan served as a mathematics teacher in secondary schools, teaching staff and teaching practice supervisor (full-time / part-time) in various university level institutes. His expertise is Mathematics Education. Currently, he is Program Coordinator and Teaching Practice Subject Coordinator of BMED program and a supervisor of BMED teaching research projects. Courses taught or currently teaching at CUHK include Subject Curriculum and Teaching (Mathematics), Teaching of Number and Number Sense, Mathematics Curriculum and Teaching (Instructional Technology and Design of Teaching Activities) and Teaching and Learning Mathematics in the Changing Curriculum. Dr. Chan is actively involved in local mathematics education communities including teaching professional development, curriculum development and school mathematics competitions. He is a member of various committees of mathematics education at EDB.
Research interests include: ICT in mathematics education; tool-based task design in mathematics education; mathematical thinking, problem solving and reasoning; spiritual development across school curriculum; religious studies.
