I found the article rambling and mostly pointless...

However, if you have a weak background in math and want to get up to speed before going into calculus and beyond, I have 2 suggestions.

1) Lial's Basic College Math[1] is adequate and will get you up to speed. 2) Serge Lang's "Basic Mathematics" is great and will cover all you need to go into a rigorous theory based college math class.

[1] http://www.amazon.com/s?ie=UTF8&field-keywords=lials%20basic... The editions basically the same... pick the cheapest

Take a look at Daniel Willingham's material and his book "Why Don't Students Like School"

Here's a review of the book: http://ed-policy.blogspot.com/2009/04/one-of-handfull-one-of...

Here's Dr Willingham's web site with a lot of articles worth reading: http://www.danielwillingham.com/articles.html

Here's his credentials: Earned his B.A. from Duke University in 1983 and his Ph.D. in Cognitive Psychology from Harvard University in 1990. He is currently Professor of Psychology at the University of Virginia, where he has taught since 1992.

I come from a very similar background as the writer. As a young man, I showed high potential for languages. So when I went to college, I loaded up on languages, graduating with 6 different languages at at least the 200-level and fluency in 3 of those languages. Unlike the writer, I chose neither military nor government work upon graduation, but instead worked as an ATA-certified translator for 10+ years, primarily translating pharmaceutical documentation and medical studies.

I've since moved into professional software development and am now rusty in the spoken languages I used to be fluent in. I work with a number of different programming languages, primarily doing web development since that's where the money is in remote work (although I also have a strong interest in embedded programming). In between, I also finished graduate school in public health (don't ask!), taking multiple upper-level biostats and epidemiology courses.

Anyway, people were always interested in how I learned so many languages. As it turned out, I used similar techniques as what the writer describes to not only learn languages, but also learn graduate-level quantitative coursework, and now programming languages, algorithms, and data structures (an ongoing task!). People are taking exception to her description of the technique as "rote learning". Perhaps a better emphasis would be on repetition, drilling, and fluency. But for me at least, this did entail things like flash cards -- Quizlet is a godsend -- and repeated, focused practice of short problems.

I have found that the technique doesn't seem to work as well for complex algorithms as it did for math and languages. Maybe because it's difficult to break down some algorithms into small parts, perhaps because I just haven't figured out how to do so yet, or maybe I'm just getting older.

But I am in total agreement with the writer that modern education does a grave disservice to young learners by discarding rote learning and repetition.

What an incredibly short-sighted sentence: "Sorry, education reformers, it’s still memorization and repetition we need.". I could not disagree more with this article. Memorization helps, but MAKING CONNECTIONS between concepts is _HOW YOU MEMORIZE EFFECTIVELY_. Memorizing is great for learning different languages. NOT MATH. Sure, maybe students are bullshitting in understanding concepts, and forgot quickly since they…

This is why the education system will never ever change. Too many people learn too many different ways. Some people can read a formula and instantly memorize it. Other's need a connection to that formula. Some need to figure out how that formula was derived in order to understand and memorize it. And some know the formula before you even show it too them.

Not to rehash what you hashed, but it depends who you are. If you are really good at memorizing, you may not need to make connections. You may just be able to memorize everything. Some people can.

I can recognize some of my experience in what she's saying -- as I've been told several times in math/stats "you don't understand this, you just get used to it."

That's a bit of troubling statement at first, but I think it's sortof a shorthand way of saying that much of the understanding available comes through the process of repeated manipulation and observing outcomes.

I've also noticed that a decade or two after going through a math undergrad, the limited material I've retained best was the stuff I learned my freshman year and had to repeatedly re-apply in other coursework.

Still, I think she may be overstating the case about the limits of conceptual understanding, though (or perhaps bringing an engineer's perspective to the discussion rather than a mathematician's. ;)

Practice is crucial, but when I need to dredge old mostly-forgotten material up out of my brain, the interconnections formed by the mapping of conceptual space we call "proofs" often turn out to be pretty helpful. There's plenty of things I can't remember that I can derive from what I can recall.

This is a good point. It's important not to overgeneralize. At the same time, for those students who learn best by memorizing, it's best not to completely discard rote learning.

As a CPGE student I must say that memorization IS key to solving problems (the essence of learning maths); it's not a traditional "dumb" memorization of proofs however.

The whole assertion of "understanding how a proof is done rather than memorizing it is how maths should be done" holds true, BUT only when you are not bound by time or a deadline, which is not the case most of time, whether you are working through a test, an exam or even on a PhD, you cannot afford losing time "reinventing the wheel"; working on proving theorems that have already been proven rather than using them directly.

The factor of time forces you to "memorize" certain concepts/theorems/facts so that you can use them directly as tools.

Personally, my approach consists in working on proving these "tools" at a first stage; understanding why they are true, then, I simply go past that and simply "memorize" them in order to boost my workflow.

In a nutshell, in order to be productive (doing maths or even physics), you must memorize shit, just don't do it blindly.

Did you even read the article, or did you read the subheading, which I will admit is a stretch, and immediately cast judgement? You used the strawman of a k-12/college student who learns something and quickly by practicing a particular method then forgets it. What about those who actually do learn this way? There are most certainly visual learners who can see concepts in their head -- a trait I admire personally.

>So many students in other cultures

Do you know every student? Every culture? Again, nothing but over-generalizations here. The article actually referenced the afterschool programs in Japan that had success.

Yes at some point you have to back and understand the why and the how, but solving equations and crafting proofs are actually two different skills in my opinion and I have met mathematicians that were stronger in either or both.

In any case, I think you are missing the point of this author. I think the authors strongest argument which is building that foundation, or "innate ability" and he argues that comes through memorization and rote learning. Quoting, "building well-ingrained chunks of expertise through practice and repetition was absolutely vital to their success" I don't think he just pulled that out of his butt. If you take the time to practice like the author did where it becomes engrained into your mind, you are in fact learning effectively.

Besides all this, what is mathematics anyways? Is it not a language? Does it not have "letters" (variables, operators, symbols), does it not have a grammar? Does it not have "parts of speech?" (an equation must have a left side, and a right side), Is it not used to communicate to others?

In any case, certainly not a terrible read in any way.

And voilà, you put it much better than I did in 5 rambling paragraphs. Memorization is key (at least for some learners), but only as one part of a process.
