(Peer To Peer Class)
(Hyundai Chungun High's special class)
(It's an exchange class where peers and seniors share knowledge)
(A class where outstanding students teach other students freely)
(PTP class - English) (Ricky / Jung Eun-ji)
(PTP class - Math) (Kim Jung-hoon / N)
(Ricky's English conversation class)
(Eun-ji willingly came to the English class)
Did you eat lunch?
(Keeping the answer short)
(Avoiding eye contact)
Do you like the color red?
(It's always yes when you don't know the answer)
(Teacher Ricky is a bit flustered by short answers) If we keep doing this, I'll just give you an example
- (Sorry about that) - 'How old are you?'
(Short answers will not get the convo going) '33...'
(Ricky's Tip: Try to avoid short answers!) 'You like Korea?' 'Yeah'
(Ricky's Tip: Try to avoid short answers!) 'Did you eat?' 'Yeah'
This is not the way to learn how to speak
If you open up your ears just a little bit
There will always be an answer like how we solve math problems!
(Don't be afraid) Just think of it as an easy task and you'll be able to answer all the time
Q. What's your favorite food?
A. My favorite food is cold noodles
(All you have to do is just add a little more to the given sentence!)
(Asking the same question)
My favorite food is black bean sauce noodles
(Here's another question!)
(Question = Answer) (Answering without any trouble)
(And now to convo time with classmates)
(Eun-ji who nailed the last question will come up)
(The male student will go first)
Q. Who do you want to travel with?
(First, get the structure from the question...)
(Glance)
(Using what she just learned)
(And it's her turn to ask a question)
What the...how do I say this
It's okay!
(Boosting up her confidence) Just put it out there thinking you're saying it correctly
Q. Which member do you like in Apink?
(There's the question!)
I especially like...
(Anticipated)
I'm a big fan of Oh Ha-young
Oh, her, not me...
(That's not what I wanted to hear...)
(The student was quite frank) Your English was good but that wasn't the right answer! Haha
(Hmph) It's okay
What Ricky Kim said
I mean the teacher said to the class
(Ricky's English class helped her a lot) was really helpful
(Simple and easy, use words that are in the question!) You just have to use the phrase from the question
(She learned how to speak in sentences in a short time) which will lengthen the sentence
(Only if I learned English like this...) I thought If I knew this method, my English would've
improved so much
(Jung-hoon's math class) Let's try to figure out the things you didn't really get
(N came to this class on his own) Let's start with Chaerim
(Jung-hoon's deskmate finds geometry hard) Geometry!
Especially the one that's related to the equation of a circle
I find that hard too
(Even the natural science genius finds it hard) It really is hard
(Explaining things worriedly) So in this case
(Let's draw the circle first) We got this circle with a value of A
(He looks a bit nervous) Since the radius is A
(Help me out, Pythagoras!) According to the Pythagorean theorem, it's X² + Y²'s
(Focused) square root
(But seems like it's not difficult for him at all!) So that's how we get
- the basic formula where - A²
(Nailed it) X² + Y² equals A²
(Looks like Chaerim understood!)
(Applying what they learned) So let's see the example here
(The equation of a circle) We're going to solve for this colored area
And Hak-yeon will come on out
(He'll do the honor of solving)
(Kind-heartedly encouraging N to solve it as he got more interested in math) Let's see how you do it, I'll help you out
(Pressured)
(Stares at the question)
- But instead of this one - No?
(Equation of circle is too hard for N)
What page is that?
(Curious about other theory) Region of inequalities?
- Here? - Yeah, that one
- Oh, that kind - Yeah
I was curious about it
(A special lesson just for N) Let's start off with Hak-yeon drawing the graph
(Carefully solving the problem) Since we learned it?
(Carefully solving the problem) If X equals 0
Y is 8
(Nods)
(Will he be able to solve it without the secret note?)
(Looks like things are going well for him) If Y is 0, X is 4
(Glance)
(Trying to get a hint from deskmate)
(Nods) (N is in avatar mode)
(Another glance) That's right
You're good!
(It's all thanks to) I learned this from the teacher
(the teacher and Dong-guk)
(The answer is?) 12
(Pit-a-pat)
(Correct!) The answer is correct
(Additional question, but why though?) But how come '3,2' gets the biggest value?
That's because...
It's because...
I haven't learned it yet
(That's something you can't guess) As you can see, this is correct
(Got the correct answer) You can see it quite intuitively
(Got the correct answer) It looks quite obvious that the value is the biggest here
And this would be the least value but
(Wants to teach the fundamentals) You got the correct answer but
if you don't include the solving process
(Math is all about principles and fundamentals) Some math contests don't count that as correct
But it's so hard...
(Extra lesson for N who finds principles hard) Then why don't we try this one?
Speaking of geometry
(Another Pythagoras time) You all know what the Pythagorean theorem is, right?
If a question asked you to prove the Pythagorean theorem
If that's the case,
how would you solve it?
Anyone?
(The puppeteer) Dong-guk?
(Not me)
(Knows what it is, but not how it works) So Dong-guk, Pythagorean theorem is
(The solution begins) This is A, B, and C here
(Students are focused too) Let's draw a square where A is one of the sides
(Showing the true sides of a genius) And let's divide this up
(Showing the true sides of a genius) This is C here
Let's divide it
(Focused) And we're going to draw the extension line
(Trying to teach how it works, not just the answer) So the 4 triangles are combined, right?
(Trying to teach how it works, not just the answer) So that's why this side
and this side has the same length
(Glaring eyes) Since this side is B
(Jung-hoon looks quite serious than ever before) With 4 triangles with 2AB
It's A² + B²
(That was the solution) Which is also C², and that's how
- we prove the Pythagorean theorem - (A-ha!)
And there are hundreds of ways
(The halo of genius) for us to prove this popular Pythagorean theorem
- (That's so cool) - And it'd be the same case
(There are many ways to solve a math problem) for many math problems that you'll confront later on
The thing is
you have to come up with your own know-how to solve it!
What's written
(Hoping that they learn) in the textbook is not the only way
(their own way of solving problems) If you prefer some other method, just go with it
if that makes you more confident!
(Applause) Thank you
I really enjoyed the class
and since he's a math genius
(Amazed by the genius) So he really taught us the basics in a legit way
