小山 正孝

Education Profession Unit (Pedagogic Researcher Cluster), Professor
Masataka Koyama has been Professor of Mathematics Education since 2007 and the Dean of Graduate School of Education and School of Education since 2016 at Hiroshima University, Japan. He received his B.Ed., M.Ed., and Ph.D. in Education from Hiroshima University. His major scholarly interests are mathematical understanding, international comparative study on students’ mathematical attainments, mathematics teachers’ professional development, and school mathematics curricula and textbooks. He has been actively involved in both the international activities such as ICME, EARCOME, and PME for improving mathematics education and the national activities for society of mathematics education and teachers’ professional development through lesson study of mathematics in primary and secondary schools.
