about yeap ban har Dr Yeap Ban Har spent ten years at Singapore's National Institute

of Education training pre-service and in-service teachers and

graduate students. Ban Har has authored dozens of textbooks,

math readers and assorted titles for teachers. He has been a

keynote speaker at international conferences, and is currently

the Principal of a professional development institute for

teachers based in Singapore. He is also Director of Curriculum

and Professional Development at Pathlight School, a primary

and secondary school in Singapore for students with autism. In

the last month, he was a keynote speaker at World Bank’s READ

Conference in St Petersburg, Russia where policy makers from

eight countries met to discuss classroom assessment. He was

also a visiting professor at Khon Kaen University, Thailand. He

was also in Brunei to work with the Ministry of Education Brunei

on a long-term project to provide comprehensive professional

development for all teachers in the country.

introduction The Singapore approach to teaching and learning mathematics was the result of

trying to find a way to help Singapore students who were mostly not performing

well in the 1970’s.

The CPA Approach as well as the Spiral Approach are fundamental to teaching

mathematics in Singapore schools. The national standards, called syllabus in

Singapore, is designed based on Bruner’s idea of spiral curriculum. Textbooks are

written based on and teachers are trained to use the CPA Approach, based on

Bruner’s ideas of representations.

“A curriculum as it develops should revisit this basic ideas repeatedly, building

upon them until the student has grasped the full formal apparatus that goes with

them”.

| Bruner 1960

“I was struck by the fact that successful efforts to teach highly structured bodies

of knowledge like mathematics, physical sciences, and even the field of history

often took the form of metaphoric spiral in which at some simple level a set of

ideas or operations were introduced in a rather intuitive way and, once mastered

in that spirit, were then revisited and reconstrued in a more formal or operational

way, then being connected with other knowledge, the mastery at this stage then

being carried one step higher to a new level of formal or operational rigour and

to a broader level of abstraction and comprehensiveness. The end stage of this

process was eventual mastery of the connexity and structure of a large body of

knowledge.”

| Bruner 1975

Bruner's constructivist theory suggests it is effective when faced with new material

to follow a progression from enactive to iconic to symbolic representation; this

holds true even for adult learners.

| Bruner 1966
