The document argues against teaching math and science in the Malay language in Malaysia. It provides three main reasons: 1) English is the primary language of scientific research and literature globally, so using English allows students access to the latest findings and developments in these fields of study. 2) Teaching math and science exclusively in Malay may improve subject comprehension but will limit the development of critical thinking skills that come from learning in English. 3) Proficiency in English is important for Malaysians to stay competitive internationally and have opportunities in universities and careers that require understanding of English-language materials and global issues.
