Like This Also Wanna Cry? WTF is Happening?

MOE approved Physics textbook teaches my nephew the wrong thing

A STOMPer's nephew came home crying after his GCE 'O' level Physics exam. He answered a question according to what he studied from the MOE approved textbook, only to find out later that it was wrong.


How can the MOE approved textbooks, which so many students use, carry such errors and ambiguities, questions this STOMPer.

Says this STOMPer:

"My nephew who sat for his GCE 'O' level exam came back crying and showed me his Physics Paper 1 (5058/01) in which Q19 says: What is the refractive index of a medium?
A the ratio of the speed of light in air to the speed of light in the medium.
B the ratio of the speed of light in the medium to the speed of light in air.
C the ratio of the speed of light in the medium to the speed of light in vacuum.
D the ratio of the speed of light in vacuum to the speed of light in the medium.

"According to the internet, which I have checked the answer is 'D'.

"My nephew who wrote the answer as 'A' later consulted his teacher after the exam and was told that the answer is 'D'.

"According to his textbook page 231 the authors say 'It has been proven that the refractive index is a ratio between the speed of light in air or vacuum and the speed of light in a medium'.

"The cover of the school textbook titled GCE 'O' Level Physics matters by Charles Chew and Chow Siew Foong and there was a seal with the words 'Approved by Ministry of Education for use from 2007- 2011'

"This was the textbook used in many of our secondary schools and endorsed by the MOE.

"If the textbook has errors or ambiguities why does MOE recommend that schools use this particular textbook?"

There is only a minute difference in the speed of light in air and vacuum. So the real goon is Bargain Hen's MOE. Does not its resorting to such trickery to stream Sporns reflect how it's bent on sifting out Sporns out of the system and reserve educational opportunities for the FTrash, who probably donch even know what's the meaning of air and vaccum in Engrish?

By looking at the answers to the question made me realized why singaporeans are not creative and can only think within a box!

Imagine students who are great at scoring in such exams may ended up in MIWs roles!!

Like 1+1 must be equal to 2 and not 1 or 11....

The wrong answer still gets you no where even if the textbook says so. This is how "dependent" the Singapore education has become on the "approved" textbook. No critical thinking were every taught on the subject. Speed of light in air, what is the definition of "air" in this case? At sea level? At mount Everest? One atmospheric pressure? What about elements contain in the "air"? Nitrogen? Oxygen? Does it affect the speed the light? Why are refractive index calculated this way? The best thing MOE should do is totally scrap the concept of a "Textbook" start using google, wikipedia. The kids nowadays are so lucky that they have these information available on their finger tips. But they most important point is to still educate them in "questioning" everything. Including whats written in the textbook and on the net. If it seems reasonable, then you have the answer.

PS: Most likely, this would never happen. The government don't want a population that questions its actions and responsibilities. They rather have a sheep like population that would do whatever they say. Instill fear in them so that they no one will question them even if they have lost billions in TemaSick.

People shouldn't be afraid of its government, Government should be afraid of its people.

Air is inhaled or exhaled when the suction on the ba na na is released, and a vacum is form, when the ba na na is being sucked...maybe Bargain Hen, the could be rich cancer surgeon..had forgotten his sciene..maybe he passed with the same textbook...now , you know the quality, we are getting ha ha ha ha ha

1 + 1= 10 in binary mate.

There are only 10 types of people, Those that understand binary and those that don't.

do you know the difference between medium and vacuum?

No not that tian ling ling di ling ling medium! Lol

This medium..also does, earth, wind , fire , gas & water...which medium, again?

The correct answer is "D" because absolute speed of light in vacuum is 3X10^8m/s.

But then cry over one question answered wrongly? I think there is something seriously wrong with our education system until people are so particular about a tree that they miss the forest.

Sign, the textbook has to be written by a local. In science, definition is very specific. Cannot suka suka say "is either this or that one". Written by "Dr" some more, maybe a vet.

Alright little boy, you lost one great important mark in your life. You're finished. No more RJC or any JC for you, not even the neighborhood ones. It makes a whole lot of difference. Now it's either Poly or ITE, wait for the news.

Your life is forever changed. You are no longer on a peerage course. Being cast out of the circle you are now just a commoner going to make a living in the same humble way like everyone else. It's all gone. Deal with it. Your rise has been doomed.

In revenge you should either: sue the department of education for a boatload of cash to make up for lost opportunities (or opportunity cost whichever you like) or you should just peddle erroneous state-approved physics textbooks to unsuspecting and innocent Sec 4 and Sec 5 students to make them suffer like you did. Maybe someday by making such an incredibly bold venture you'd be rich and you'd live in a castle or a Swiss cottage with lots of security guards (because both angry students and severely embarrassed state officials will come after you) and a robot nanny (because your mother can't live forever to change your diapers even when you're 50), and live happily ever after.

The skull is scary and will send him crying to his mother.

Don't get it?, what's the drift?
