This book constitutes a very good read as it has reverently recorded the history of the implementation of the national language policy, i.e. the Malay language as the medium of instruction in the Malaysian education system. This book containing three main sections: (1)The history of medium of instruction policy in the Malaysian education system.(2)The implementation process and its challenges from 1970- 1983.(3)The implementation of English language policy in Malaysian education system.The effect of globalisation has caused many developing countries to adopt and use English in teaching Science and Mathematics in primary and secondary schools. Even though the main issue is close related to an educational agenda, that is, to give the language skills and subject content instruction, the medium of instruction policy also involves social and political issues - who would benefit the most from this language policy? What language policy would be the most suitable for this multi-ethnic community, what is the best language policy that would maintain the equilibrium between the different needs and nurture a stable political environment?
