Whats the deal with common core, I hear a lot about it but is it "good"?
>>
>>41311564
It's good for creating better non-thinking human beings. AKA just following instructions and able to solve something exactly how you want them to instead of thinking themselves.

It's good at stifling high IQ people and creating better working bots out of low IQ people. So basically exactly what people want out of public schools.

All actual mathematicians like it, it deals with shit that's poorly covered before like distributive property, in order for your dumbass kids to finally start algebra before junior high.

Everybody else hates it though.
>>
Should we have a national standard to make sure people are being taught the necessities?: Yes

Should it be based around SJW retard politics?: No

Should it be literally anything more than making sure people are getting taught to read and add numbers?: No

It's necessary to make sure we don't have kids getting totally shafted and left behind, creating a 3rd world welfare shithole in the middle of our country, but there needs to be room for differences in the way different states do things. It can't be an "our way or the highway" kind of thing.

>one size fits all education

Its no hidden secret that our education system is failing and its for a plethora of reasons.

Anyone who has been to college knows that education majors are some of the lowest caliber students out there.
>A failing student's parents blame the teacher's fault, instead of taking the responsibility to discipline the student
>Standardized tests are a fucking joke
>it doesn't pay to be critical of a shitty teacher and speaking your mind in papers might net you a F if they disagree with it.

Finally, it teaches to the lowest denominator...a denominator that typically doesn't want to learn. What I could learn in a couple days would be taught in several weeks. I can't tell you how many games of euchre and rummy I played in a single day and maintained my "A"

This.

Everyone hates it because no one actually paid attention in Math or was curious enough to know WHY something works.. they just memorize formulas and pass the test.

the distributive property is the entire basis for mathematics in algebra and above. without the distributive property none of it works and it's completely passed over in all levels of mathematics from pre-algebra to calc 3.

most people, even in calculus, today have a fundamental learning problem because of the way we learn to do math at an early age is flawed.
>>
>>41313381

And the solution isn't in common core.

Common core is teaching cashier math and granted, the foundations of maths they will no longer have time for with the "improvements" in social studies and history.

Everything I ever needed to know about common core, I found in a civics handout on the bill of rights which pointedly refused to quote them... Since if they did, their summaries would easily be noted as the bullshit they are.

Every kid learns cashier math currently.. addition and subtraction no matter how you learn it is cashier math.

I don't like anything else about common core, the changes to history etc

but something with the way our education system teaches math needs to be changed fundamentally if we expect to get more people interested in math and sciences.

every time someone says 'i just dont get it' when they're 17 and doing algebra 2 or pre-calc is because of the way they learned to count in grades 1-7 and because of the way pre/algebra1 was taught to them completely blowing past fundamental abstract concepts just so they can memorize a formula and pass a standardized test.

I take issue with this. It should not be so fragmented. Many of the underlying concepts of all these fields can be taught at an early age.

Later on, they develop into higher forms, like the symbolic understanding of calculus, and all the math behind quantum physics, and having real dissections of history and literature and philosophy.

But all of that should be covered in high school, yes.

>>41313816
Exactly.
>>
>>41313756

The method to correct this is more experimentation, not standardization.

I went to a montessori school in my youth; My math skills were fantastic due to the tactile and kinetic way they taught math.

If you let common core through, we'll see a insignificant improvement and educational administrations without any opportunity to try new methods for fear of federal censure.

The biggest problem is that almost all my math professors just wrote shit on a board and never told us WHY they should care about it and how to actually get to it. Especially to middle schoolers who get boners from a gust of wind. I agree, you can probably push up most math by at least 2 years, but this is a bit much.


And with common core, its more inefficient than teaching long-hand division. My old man taught me short hand division before they taught me long hand...and they almost failed me because I didn't follow their way. Now they expect kids to draw a bunch of line and circles?

Yeah but with No Child Left Behind, the problems were the real high performing schools and the low performing schools.
I went to a high one, even though we were top 10 in the state, we reached a point where you just couldn't improve without physically expelling the trailer park kids.

You can argue that common core is better for higher-level math, fine, implement it at the college level, not at the high school level when most of these kids are going to be taking Pre-Calculus at most.
And even the gifted kids will only be taking AP Stats, Calc 2, and maybe some higher level Algebra.

The math part of common core is controversial with all the number diagrams and shit but in reality it really only makes a few minor changes to the math curriculum between Kindergarten and 1st Grade. It adds a few new sections to the curriculum on basic arithmetic (adding, subtracting, multiplication, division) where it breaks down the mathematical logic of each algorithm students learn so that they can develop more competent mental mathematics.

Ex. 271 - 189 = 82

We learned it:
>Take one from the tens place. 11 - 9 is 2
>Take one from the hundreds place. 160 - 80 is 80
>100 - 100 is 0 so the hundreds place goes away
> ⇒ 271 - 189 = 82

Students under Common Core will learn it the same way eventually, but before that they spend a couple weeks learning:
>189 → 190 = 1
>190 → 200 = 10
>200 → 271 = 71
>71 + 10 + 1 = 82
> ⇒ 271 - 189 = 82

All it really does is add a few extra steps which eventually just become "mental math" when you learn the compressed algorithms for stuff later. Same shit goes for multiplication before they learn to memorize times tables and do column multiplication. Same shit goes for division before they learn to do long division. Like I said, basically everything from 1st Grade on is pretty much unchanged.

The logic here is that by taking a few weeks worth of lessons to focus on this shit early on instead of leaving it to the students to develop mental mathematics on their own, you don't end up with as many people falling behind when you get to more complicated arithmetic. If less people are falling behind in arithmetic, less people will fall behind when you start algebra, and then geometry, trig, calculus, etc etc.

That people are making such a gigantic fucking deal out of it is ridiculous.


... NOW, the Common Core changes to history, government, social studies, etc? Yeah, that's all COMPLETE and utter HORSESHIT.
>>
>>41311564

It's another expensive experiment that the US government will throw at it's education system to figure out the answer to the question, "Why can't JaTron read?"

The US has been doing this crap for decades. There is no super-effective undiscovered education method.

What got the US to the Moon? The same education that taught the Americans who worked on it, and the Germans who designed the rockets. It sure as shit wasn't 'Common Core.' But we can't have that, oh no. We need something 'new' because 'old' = 'bad' by this planned obsolescence society.

>The US has been doing this crap for decades. There is no super-effective undiscovered education method.
This is true. Common Core isn't the first "New Math" and it won't be the last.

>What got the US to the Moon? The same education that taught the Americans who worked on it, and the Germans who designed the rockets.
Funnily enough, there was a huge push during the early days of the space race to convert American math education to the Soviet-style "set-theory" form in an effort to try and close the perceived math and science gap.

The "New Math" of the 50s and 60s was mocked and derided by comedians and comics of the day and by the late 60s had been phased out for yet another 'Newer Math', which in turn was phased out for the format we learned during the 80s and 90s which is in turn being phased out for the Common Core curriculum, and so on.
www.youtube.com/watch?v=UIKGV2cTgqA

Twenty years from now the students learning Common Core now will, like us, and our parents, and our grandparents, be wholly convinced that their method is the only "right" way to learn math and that whatever new curriculum is being pushed on kids in the 2030s is a liberal socialist conspiracy to corrupt our children.

>>41314999
I teach physics (college GTA) and while it would be great to start teaching modern physics (quantum physics, SR and GR, modern astrophysics, solid state, plasma, etc etc etc) in high school physics, that shit is NEVER going to fucking happen because there's very very little you can actually teach high school students about modern physics or more complicated physics without requiring them to understand differential and integral calculus, vector calculus, differential equations, series, linear algebra, etc etc.

Hell, College Physics for non-majors is taught strictly with algebra, geometry, and trig because we know that 99% of students aren't learning calculus before college, and that's not something that's about to change.

So, unfortunately, this means that any effort to teach modern physics in high school is going to be basically limited to extremely simple algebraic problems and qualitative explanations of theories and phenomena.

When "No Child Left Behind" started, he couldn't attend the class anymore. I don't know that the class existed after that.

I can't keep up with that pace. I think we should start by making sure public schools actually employ math teachers to teach math, even if we must pay them more.

I'm assuming what he's talking about is that when learned people do math in there head they typically employ a type of counting up for subtraction. After you do math for awhile you develop the technique somewhat subconsciously. Common core is actually skipping the foundational core part of mathematics and trying to go directly to advanced mental math employed on paper. It's good in theory...kinda, but it's going to be disastrous in practice.
>>
>>41314999
It is a shame you did not attend a high school that did offer such a course.

One of the schools in my area offered advanced courses in two blocks available an hour before and an hour after the normal school day.

They taught calculus, quantum physics, advanced art and music courses, medical courses (CNA and so forth), and AP English courses.

One had to live within the city limits to attend. It was extremely expensive tuition plus the parent had to buy all the books if they lived in the county.

But calculus is so easy. If you can run and jump or throw a ball, you know calculus. Teach that at the same time as Newtonian physics, and it's a lock.

I firmly believe many of the rest of these things can be taught at an early age. It's just going to take some exceptionally bright people to figure out how -- I have the utmost respect for educators in part because I'm not that good at it myself.

You wouldn't like it if people are better informed on your field of study? Math doesn't have bias. It's not something you can be red pilled or blue pilled about (Wildberger disagrees, but I digress). What it does have are stupid fucks, and Math gets a bad reputation because people think they have to memorize this, like Biology. No, people shouldn't, what educators should be teaching is why some application of Math works. After learning Euler, I'm convinced that anybody can breeze through Trigonometry.

Like, that was one of the success stories that stuck out.

Yes because finding a tangent line or knowing the names of different bosons will bring world peace and end hunger. Doesn't matter if everyone knows how DNA replicated if people in a democratic society don't know how to work through political rhetoric or can't comprehend Metaphysics and all the moral and ethical questions that come from it. If we're all stuck in a economic system that is completely immoral it won't matter if people know particle physics because they're still stuck in that system and won't know it.

For me, it was only during AP classes that I was forced to have to derive the necessary equations, laws, and rules, on my own, based on having the underlying basics drilled in to me. Maybe that's not for everyone, but I brought myself up that way after being given the gift of reading and access to any book I wanted.

Damn near failed out my freshman year in college. But that's how I learned it wasn't going to be cut and paste and fill in the blanks easy anymore.

Kind of like when my parents made me get a summer job, and later told me I had to gtfo or pay rent.

You're greatly overestimating the cognitive ability of teenagers. Just looking at SAT reading comprehension scores across years, you can see they develop many critical thinking skills only in their late teens.
>>
>>41314887

Every generation is going to deride the next generation for deviating from what they were taught and the method in which they were taught. Heck, each generation is going to clash with their predecessors and their successors no matter what. That much is a given.

The issue arises when we cannot stop trying to fix the 'problems' we have by introducing new methods, instead of sticking to one method and fixing the people teaching it.

Look at all the 'new' tech we have now. LCDs, and solid state memory. LCD was discovered in the 1950s. We were perfectly capable of doing great things. And we did so because we perfected the method of teaching.

Sometimes it's just better to perfect the wheel, rather than focus on constantly trying to reinvent it.

Parents get confused because parents don't know math. I don't know math. I got an A in linear algebra and I don't know anything about math it's beyond my critical thinking and creative capability to actually understand and that probably has a great deal to do with the way I learned core concepts in pre-algebra.

And the higher in math you go little things like that start to build up and ruin your critical thinking ability until you're just "learning answers" rather than learning why the answers are answers.

So, while I'm against the political aspects of common core I'm for a change in how children are taught to work with numbers, definitely.

When you get into higher math, this is absolutely true. Some people can handle it when you just spray a huge equation across the screen, but, for the most part, that won't play unless you explain, at an intuitive level, what the hell that all means and why it's there.

But we're talking about common core. In other words, things like adding and subtracting. Get real.
>>
>>41316362
Yeah.. but that's cheating.

Because you aren't actually subtracting 3 from 4 you're subtracting three 100's from four 100's.

And that might look like nothing, but those shortcuts build up over years and kill your ability to critically think.

a 5 year old has no concept of 100's. This introduces it without shortcuts and makes them think about what they are really doing when they take 316 away from 427 rather than breaking it into 3 different single digit subtractions.

Thanks! Reading the forward it seems on the up and up. One thing stands out to me. I understand not trusting big government bureaucracy and social marxists to raise children, but I don't really trust the dumb parents either. Most aren't really invested in their children's future either.
>>
>>41316133
It's more beneficent than just showing them how place-value notation works, and teaching the arithmetic from there. I swear to god, if we just tought kids numbers as they are written, rather than just as beans or some shit, there would be a lot less trouble down the road.
>>
>>41311564
Sciencefag here. Its highly idealistic in the sense of what they are trying to accomplish. Does it force students to think critically? I'd say yes, but as most people covering it are of young age who could probably care less, I am not sure. I think common core is nice to look at myself. Its quite clever, usually trying to explain things to students without using fancy words.

>>41316815
I could see counting the physical objects being important for visualizing the concepts of addition, subtraction, division, multiplication, etc. But you need to eventually switch to numbers by themselves so they don't get trapped into trying to visualize larger and larger quantities everytime.
>>
>>41316882
Exactly. If I were in charge of early mathematics, it would consist of 3 phases

>Learning how to count by slowly abstracting quantities of physical objects into numbers

>Learn how to do basic arithmetic, and the hierarchy of binary operations (exponentiation is repeated multiplication, which is repeated addition, which is repeated succession)

>Do away with the concepts of subtraction, division, and roots as their own operations, and teach them as the opposites of addition, multiplication, and exponentiation

With all due luck, kids would be adding negative numbers, rather than subtracting positive numbers.
>>
>>41316814
Dumb parents are a very real thing. That's kind of a separate discussion.

What I do for a living is look at problems and try to figure out how to solve them. That's part of the reason I am in favor of public education and subsidies for kids to have access to educational materials and things like that. (Maybe that's why I spend too much time on 4chan.)

But I think what we're ultimately facing here is a large-scale sociological, or even spiritual, problem. I think that's a discussion that probably belongs in a different thread. But I believe in having the right mechanisms in place at a low level in order to enable the whole system to work, because we need every part of the system to work. That's the only way to do it if you're in it to win it.

That's exactly what learning to add and subtract like this does.

>>41316652
>no, that's called understanding what numbers mean, and how to work with them.
It looks like it's dumbed down but it isn't. It's the same thing just this way shows them what they are actually doing.

We just have a hard time looking at it objectively because we aren't 1st graders anymore and addition is too easy for us to understand conceptually.

We're talking about kids that maybe a year ago had to use their fingers to visualize the number 5.

I don't really see a problem with alternative ways to learning, but I haven't read any studies on this way.
>>
>>41317073
Numbers aren't objects, they are abstract quantities. Teaching arithmetic any other way than algorithmic manipulation of abstract quantities is just setting up a child for failure.
>>
>>41314674
The problem is that instead of letting students realise the process for themselves, they're putting it on paper.
>>
>>41317073
I'm sure it's a helpful learning aid for some. I've had it demonstrated to me both by teachers and by little kids.

But the bottom line is that they need to have a mastery of basic symbolic manipulation. This is the basis of language. It is something that sets humans apart from their genetic predecessors. It is the basis of the development of learning, and of being able to pass learning down from generation to generation in order to be able to go beyond the stone age and figure out things like how to have laws and civilization.

I fully reject the notion that this can be abandoned. Not unless we want to go back to being retarded slaves who only understand pictures. Not unless we want to displace literacy.

...How could they teach math without that being blatant? How could you avoid a child pointing that out in every class? Either Common Core is much worse than I can possibly imagine, or I'm overestimating children.

I'm just saying you've identified the problem, but I don't see any solutions. There's no great wiseman that is willing to guide curriculum without his own bias and agenda polluting it. Supposedly impartial liberal think-tanks and assessments are the worst culprits of internalized bias and lack of self-awareness.
>>
>>41317214
Sorry to say brah, but most kids don't learn that subtraction is adding negatives till like 6th, 7th grade. In fact, most teachers actively prevent students from bringing up negative numbers, saying that it's impossible to subtract a bigger number from a smaller one.

They don't learn division is actually just multiplication by the reciprocal till like 8th grade either, and you'd be lucky to find a kid pre-10th grade that knows that the square root of that number is actually that number raised to the one half.

The kids that can avoid multiplying by reciprocals entirely by making the reciprocal a number raised to the negative 1 are an even more rare breed, most students don't even learn about negative exponents till 11th grade.

This is in Texas though, I'm not sure what the situation elsewhere in America is.
>>
>>41317214
Hence the importance of parents in the development of a child, and good parents at that. As humans, we are all imperfect.

But if you want to know about think tanks, check out, "Foundations: Their Power and Influence" by Rene M. Wormsor, who was general council to the Recce Commission (a congressional commission following up on the Cox (lol) commission) that investigated whether or not our tax-free foundations were being unamerican or not. It's very insightful commentary on just what happened to academia in and around the 1960s and how that all worked.
>>
>>41317119
This is more abstract that the way you and I learned.. The whole point of learning it this way is to abstract the place value of a number rather than looking at the number as a whole.

Learning an algorithm does nothing for your brain development.

ie 425 = 4 100's 2 10's and 5 1's
>>
>>41317324
I can barely remember learning that, and my whole class learned it.

I remember 1st grade some kids were having varying difficulties learning to read. That's like five years old, so I guess those were the kids who weren't read to as a child.

Actually, maybe we were also learning to add and subtract in first grade. Yeah, I remember these test books we were taking about halfway through. Some kids needed help with that, but we all had to do it.

I think maybe some kids still needed help with that in second and third grade, too, but that was a minority.

Seriously, this is the kind of shit you need to put in a kid's brain early on when it's going to be able to encode these things rote.
>>
>>41317389
Like I said, teaching it any other way than the algorithms in which arithmetic is based is just fucking with the kids head.

By the way, you're wrong. It's not "4 100's, 2... 1's", it's 4(10^2) + 2(10^1) + 5(10^0)

Place-value notation works on the mechanics of exponents (hence being able to work with decimals in the same system), not hundreds, thousands, hundreths, etc... This is why it's called the base 10 system, and this is the way it should be taught.
>>
>>41317389
Now 5th grade, I remember this. I remember this clearly.

We were given these workbooks to fill out by using logic. It would be the equivalent that Guess Who game -- just crossing out impossibilities until you got the right answer. Symbolic logic would have been a bit much, but we could at least count on our fingers if it came to that.
>>
>>41317463
Exactly my point. Children are smarter than people give them credit for, and I firmly believe that teaching elementary students arithmetic as it is, rather than how it has been simplified, is much more effective.

A very positive externality of this is that now we can get rid of PEMDAS, and institute a flat "left-to-right, inner-to-outer-brackets" as kids will understand the exact relations between operations

Canada, you've shitposted enough tonight already
>>
>>41317578
Well, there still is an order of operations thing, even if you take out the brackets. And nobody really wants put in all the brackets all the time.

Funny story, I was working with a like a seriously smart old professor just the other day, and pointing out why we would need to require brackets for our particular symbolic language as a rule, even though we had been playing fast and loose with them on the whiteboard for the past few years. It took him a little while, but then he was like, "oh, yeah, ok, you're right"

So maybe at a higher level you don't need to be so pendantic in your daily life, but it's important to be able to do that.
>>
>>41317690
That can be solved easily just by removing the multiplication sign entirely. Sure, it'd be a bit more cumbersome, but it would be much more readable

So something like
4 + 3 * 5
rather than having to use PEMDAS and multiply the 3 *5 first, could instead be written as
4 + 3(5)
Students should at this point have learned the distributive rule, and knowing to do the inner most parenthesis first, would distribute the constant or variable first, before adding the terms.

Hell, just teaching them about terms early on would get rid of PEMDAS, as there would then be no difference between 4 +3(5) and 4 +3x, students would be able to recognize anything with a bracket as it's own term, regardless if it's a constant, variable, polynomial, whatever.

90% of my college physics students every semester can't understand why A = ½B implies B = 2A or why they can't add something in units of meters to something in units of degrees Kelvin. Half the people I know need an app to figure out a 10% tip on dinner. The woman who works the register at the dinner next to my office doesn't know how to make exact change without a calculator.

... clearly people aren't fucking realizing shit for themselves.

If there's even the slightest chance of a minor modification towards early learning helping reduce that percentage twenty years from now, I think it's worth a shot.


The liberal arts curriculum shit? Sure chuck it in the fire, but quit bitching about the math.

Thanks brah

Even further more, take the expression
3 * 4 + 2 *5
and convert it to
3(4) +2(5)
This would be the best way to teach children about terms, as you can't directly add 3 fours and 2 fives. Instead, they would have to convert it to where they're the same order of term, which would be
12(1) + 10(1)
Which can easily be added to be
22(1) = 22
In just the same way that
3x + 5x = 8x
