A thought on the english science and math policy

One of the most recent happenings in Malaysia's education system is the reverting of the policies of teaching science and maths back to teaching them in Bahasa Kebangsaan.

Some question comes to my attention on this subject though, what are the governments doing, shouldn't they plan out this thoroughly before implementing? Why isn't this policy of teaching in English working? I know one thing is for sure, the six years of teaching science and maths in English is an atrocious experiment!
Maybe teaching science and maths in English is a badly flawed idea?

What really disgusted me is that the government virtually knows that this changing to English implementation is flawed, and they should have known that their science and maths teachers could not teach in English, yet they had this experiment running for six years! Meaning that we had a whole generation of students undergoing this massive change but all for nothing. And now we will have another generation of pain as thousands of students get stuck in the education limbo while the government phases out this failure of a policy.

What is more, all these are totally unnecessary. They could just have at least tried to implement other changes first such as preparing the teachers to use English in the classroom, but they did not. They pushed through the policy when it was plainly not ready.

In summarizing, we have just spent six years in an experiment, and have no improvement to show from it, because of a flawed plan. I have no blame for the government to end the policy if they wished to, but I blame the government for keeping it up for so a long period, even though it is already obvious to almost everyone that this could not have worked the way the government said it would.

Nevertheless, the implementation is a good one for students who already have the foundation in English, with teachers who are capable of delivering them in the language.
Perhaps one suggestion to this issue, is to let the parents and the individual schools decide on the language to be used.
