1st category:
"I don't know what i do not know"
2nd category:
"I know the things i do not know"...
3rd category:
I already knew the things i dont..
So which category are u? The first , second or the third situation?If u are among the third ..all i have to say is well done :)..your problem is already solved. If u fall on the second category, personally i think u still have the chance to solve it if u really focus on finding solution to the real problems.
However if you are among the first category..then u really need to find someone that can help you to clear the air.
I have to admit that every year i will face quite large portion of student that falls onto the first category.Usually in the ice breaking session , i will ask them..what course will u take after SPM? Well as expected most of them will answer : I dont know..or i'm not sure.
It is important for us to get to know things that we dont. If u still clueless about what u are going to be in the next 5 years.. u should start to find it out now. But if u do nothing about it..then u'll end up telling yourself that i'm still do not know what i'm supposed to be.
Let me share u another story of my experience.Recently i 'm about to have my first lesson with a form 5 student who failed his mid term exam..I asked him about topics on archimedes.The conversation looks like this:
Do u understand the Archimedes Principle?
He said "NO".
Then i asked..which of the application part you dont understand?
He replied.."i dont know."
.. this is the clear case about student who falls on the 1st category. He is still trapped in a situation..
"i dont know what i do not know".
When we learn physics in SPM, we need to know things that we are supposed to know. If u still clueless about certain chapter..u need to find out the things that u still do not understand..This can be done by proper guidance from a teacher, friend or perhaps your tutor.Don't be shy to ask them questions even if the question might sounds like a 'stupid question'. I always encourage student to ask me question even if it sound a bit ridiculous.At least he is trying to seek things that he doesn't know. My wish to all tutor and teachers out there..dont ignore these student. Please guide them for at least getting to know the things they dont.
If u are form 5 student..here are some examples on things that u need to know about first subtopic on electromagnet. Ask yourself all of these questions.
Can i explain what is electromagnet?
Can i draw pattern of magnetic field in a straight wire?
Do i know what do these symbol mean?
Can i draw pattern of magnetic field in a coil?
Can i draw pattern of magnetic field in a solenoid?
Do i know how to apply right hand grip rule?
Do i know how to determine north pole of an electromagnet?
Do i know the factors that influence the strength of an electromagnet?
Can i explain how electric bell produce sound?
Can i explain how relay circuit works?
Can i explain how circuit breaker works?
Can i explain how telephone ear piece produce sound?
Can i explain why soft iron core is used in electromagnet?
Can i explain which shape of iron core is the best for an electromagnet?
Can i explain why strength of magnetic field in the middle a current carrying coil is stronger? Can u answer all of them?? If u cant..please dont ask me for the answer lah :)..
Ask your friend, teacher or your tutor .If they can't ..at least u have let them discovered the things that they still do not know :)
If u 've found the answer ..u can proudly say to yourself, :
"I already knew things i dont"
I leave u guys with a point to ponder from this quote :
“I am the wisest man alive, for I know one thing, and that is that.. I know nothing.”
― Plato
