what the fuck is precalc anyway? we had derivation and integration in high school, but that stuff is calculus so it cannot also be pre-calculus.

[Anonymous No.11823160]

>>11823142
basic analysis of functions, domain and range, trig, introduction to asymptotes in preparation for limits, possibly very basic matrix algebra, maybe a week or two on summations, additional practice with elementary algebra, and optimization problems without calculus (mainly the set-up, using ideas about compositions of functions, independent variables etc.). Its all topics that would be better taught at a younger age or subsumed into the general single-variable calculus courses.

I had it all in Poland in an extended math class in high school. We didn't have integrals tho, nor a mention of imaginary numbers, nor a mention of a natural logarithm or e constant. The age is 15-19. It's pretty shit compared to US and UK, idk about the rest of Europe

[Anonymous No.11823216]

>>11823209
Not even log and exponential functions? That is kind of shit desu. Frogs, russians and g*rmans are always making fun of us for not doing analysis in highschool so I would imagine that it is a bit more accelerated compared to the US.

Now now, it's not all the school's fault. The ethnic composition of students also went to shit.

I mean, look at PISA scores in Asia vs Europe vs South America vs Africa. Can't get blood from a stone and can't get a 20 year old African to understand derivatives.

>>11823160
We learned all that in algebra
precalc for me was trig identities, exponent laws, logs, pretty much an expansion and combination of everything up to that point
This was almost a decade ago though so I'm a little fuzzy

[Anonymous No.11823233]

>>11823216
We did have log and exp functions, just not with e base/power. We had vectors, but didn't have matrixes.
And we had differentiation and derivatives, but no integration.
Also germans and frogs surely have better education system. Russians I don't know, but they're pretty smart.

iirc Zorich's Analysis text was written for Russian prep school kids. I'm still surprised I thought all the former eastern bloc countries had top tier maths education.

My highschool only required geometry to get a diploma. CAHSEE had some algebra but if you knew what a triangle was you could work your way through it, since /pol/ changed all the CAHSEE math questions into easy word problems to fuck with mexicans and enforce the state's English language requirements.

I'm class of 2005

My high school education was pretty shit. My undergrad wasnt the best either. I didn't catch up until grad school. I got my shit rocked but I'm doing well now. It sucks because people's votes matter but they dont know how to interpret data, perhaps the most important tool for understanding anything. At least you can overcome a poor education even if most people dont try to

Well desu it wasn't "bad" per se, of course we've covered more topics that I said, but it's just not the same path as in US and here the mentality is that if you're interested in math you're gonna learn that in uni. It wasn't so easy as in elementary/middle school where I didn't have to learn at all, but not so hard to have troubles with passing a grade.
Here's what we need to know for the extended national exam at the age of 18-19 (in addition to a non-extended stuff) https://www.matemaks.pl/matematyka-matura-rozszerzona-kurs.html

and translate if you want
In short: real numbers, abs value, logarithms, algebra, operations on polynomials and its factorisation, rational functions, homographic functions, domains, range, sets, probability, equations, inequalities, other functions like logarithmic and exponential, sequences, trigonometry, planimetrics, geometry, solid geometry, limits, derivatives, monotonicity of functions, extrema and local extrema.
So not completely useless, but it's a crooked path and not from the ground up as in US.

I have the mid level Australian year 12 textbook from 2012.
The contexts page has (i'll be paraphrasing);
>Trigonometry: Sine and Cosine rule
>Indices
>Sets, probability and tree diagrams
>Counting: multiplication principle, addition principle, Multiplicative reasoning, Addictive reasoning
>Functions: Graphing functions, Vocabulary, Domain and range
>Central Tendency and dispersion: yeah
>Boxplots and histograms
>Sequences: Arithmetic, geometric, growth and decay. annuities
>sampling methods and capture-recapture
>normal distribution
That's book1
Book2:
>Functions and graphs
>Differentiation: Determining gradient at a point on a curve, Limiting chord process notation, finding the tangent at a point y = ax^n, differentiating f(x) +||- g(x), The product rule
>Applications of differentiation
>Anti differentiation
>Bi variate data
>Moving averages
>Linear Programming
>Area under a curve
>Project networks

It makes sense, basic precalc math and algebra is not required for non-university jobs anymore. Most people will only need to learn to use systems on the job that does arithmetic for them.

My impression is that every American that wants to study STEM does AP classes which are roughly equivalent to A levels and other international standards.

There are plently of students all over the world that never learn precalc, it's not important to most of the workforce.

My bestfriend in high school never even took algebra. At the time you could graduate as long as you had three math units. You could take classes like Consumer Math to satisfy the requirement. He now owns a small chain of auto parts stores. What good would it have done for him to not graduate because he can't do pre-calc?

That would dismantle the myth of education being "the great equalizer". Even suggesting that certain students would be better suited to vocational training than failing the same math course for four years would have you branded as every "-ist" they could pin on you.

I think school should concentrate more on core skills like objective reasoning, logic, axiomatic systems, a bit philosophy... This will hopefully lift the general niveau and support individualism. Teach the kids how to think, not what to think.

I dont know what precalc is. In Serbia maybe 20% or less get to learn integration and that is as far as you can go unless you go to a specialized math school, and its really stupid how they attempt to teach it, no wonder kids hate math

I was remedial as fuck in hs math and I only graduated with algebra 2.
Wasn't until I got older I realized that its an interesting field and kicked my own ass for all those years I spent being too cool for school.
With the exception of geometry. I'm really good at spatial reasoning and having things put into the framework of physical objects in a space was super intuitive for me.

Drilling practice problems is the best way for the vast majority of people to develop algebraic intuitions, and math education has moved away from rote learning towards concept instruction. They never master the mechanics, and they eventually forget the concepts anyway, just like they forget most of the books they read in freshman English class. The problem was never that drilling doesn't work. The problem was always that average to mediocre kids are also usually too lazy to do their homework and have average to mediocre parents.

I agree with this sentiment. People these days, especially in math and physics classes think that understanding the material generally is enough without actually applying the knowledge. The application solidifies this understanding not unlike muscle memory while playing the guitar.
