Ammiel Wan
M.Ed, B.Bus, PGDE, Ad.Dip (Math)

After the successful completion of his Masters in Education under the MOE scholarship scheme, Mr Ammiel Wan is presently the Dean of Curriculum as well as HOD of Mathematics with one of the top-performing schools in Singapore. His passion and belief that every child can excel in Mathematics led him to create an alternative approach to problem solving six years ago. The emphasis in his approach goes beyond procedural knowledge, and is intended to help pupils develop their conceptual knowledge to solve mathematical problems more effectively. Tested and proven on different ability learners ranging from the gifted to the below average, his  approach  also increased the school PSLE distinction rate from an average of 58% to close to 80% within a short period  of three years, making it one of the top three schools in Singapore in terms of PSLE performance. His first book sold more than 12,000 copies in just two years and is used by many primary schools in Singapore. He has also presented at various educational conferences and trained many teachers in workshops. In 2006, he was awarded the “Fellow of Teacher’s Network” by the Director-General of Education. Today, he is more involved in training the HODs as well as their teachers in various schools, helping them to implement the curriculum changes.
