What I know about PPSMI is that, its about using English in the the teaching mathematics and science. The medium of instruction and the lesson in the class will be conducted in English. From my reading, the rationale for the decision to change the medium of instruction from the Malay Language to English for the teaching and learning of Science and Mathematics subjects was made based on the governments concern on the nations human capital development towards achieving the standard of a developed country, as well as an early preparation to compete in the era of globalization. It is widely known that the field of science and mathematics form the basis and have a crucial role in the progress and development of a country. Various innovations and discoveries in these two fields happen rapidly and information access is mostly in the English language. English language is also the language spoken internationally and mastery in this language would allow easy access to information in these fields.In conclusion, the policy decision to implement PPSMI was made to ensure students mastery in science and mathematics in view of the fact that most of the sources are available in the English language. Indirectly, it is also hoped that the implementation of PPSMI would contribute to the enhancing of students command of the language.

-To improve students' capacity in English language. The source of input will not only from English class but also from other subjects. - English exploration time not only restricted within a week in English subject only yet it will be in science and math subjects as well. It will be a good platform for the students to explore English language in other structures and terms. Related to the next point.- Acquire the students with important technical knowledge. This knowledge will assist student to obtain necessary skills that will turn them into a professional career such as doctor, engineers, architects, industrial designers and so on.- Student familiar to use English when they further their study abroad because at the international level, English is used as a medium of communication with other people.- Students will have a good command of English, because they are able to transfer the information with expertise in that language and this capacity will expose students to the competency to compete in the era of globalization.- One of the disadvantages of PPSMI is that, it causing confusion to the student caused by the teachers who are having a weak English command. The teacher will having difficulties to give instruction and the pupils will probably get confuse easily.-Learning of Science and Mathematics become more complicated for the students where they need to translate the instruction in order to understand it. Consequently, the students will be facing a lot of thing to do not only dealing with mathematics calculation but also need to focus on the language involved.
