so what if the student master the math science in english but cant even construct a proper english email

that is why i said , what is  the objective of PPSMI? improve science math or english?

Why don't all in English not just science n math. It's better, else the kids will hv headached switching between languages..... Imagine u gather with ur friends. Need to speak malay to Ali, mandarin to ahkow n then tamil to muthu.... Better all speak english

Brunei no problem at all using English in teaching Math, Science subjects...

Brunei > All

Use Math to teach English

because they all will still need to learn to speak english to be successful on a larger platform?

That would happen if we were still in the 10th/11th century, but since then math has progressed to more than these Arabic words and concepts.

Not saying that.

From an efficiency point of view, learning english would be the most efficient in terms of effort to gain.

BM is an indulgence, some may not be able to afford (learning capacity)

well because we indulged and picked BM to be the compulsory language

limited resources demand efficient use of what is available.

learning capacity... time.

not everyone can be multilingual comfortably.

and are the students mastering all of them?

teaching is one thing... the result is another

Well most non science subjects use word that are commonly used in conversational english. So to translate them isn’t that hard.

Like you said, since you already go through the transition phase and learned the subject in depth, it is easy for you to translate all the words that i listed. But for kids in school who’s trying to read references in english or to watch documentary in english, they will be having hard time to understand what is being explained.

To be honest, if the notes i read just now didn’t come with diagrams, it would take some time for me to find equivalent words in english for the BM words i listed above.

But i am an engineer, so equivalent words to be substituted alone would be enough for me to understand, but for students, the might have to reread the whole chapter to understand, not to mention the time to memorize the new terms.

Well that is a good compromise if the government (and DBP) is willing to do. Stop translate all science terms and use english term instead for scientific terms especially words that are seldom used in conversational BM.

Or in all teaching notes & and text books, make it compulsory to put english term next to the BM term, maybe in bracket and italic so that the students can learn both terms simultaneously.

You are setting up a straw man of what Tun is thinking. All he wanted is for us to grasp and understand science and technology of modern world faster. Not becoming an Englishman. And looking at the current education and the dismal proficiency level of many graduates, one wonders if we will ever become the industrious and innovative Japanese.

Before you become an up to date inventor you need to understand what is the current tech and science. You can also start from scratch but that will take you much longer.
