TL;DR: Study foundational blocks by repeating then until you understand. Keep repeating as you build knowledge and move to "harder" things. I like the message, but not the messenger. Articles like this, in my point of view, fail to delivery their messages in a better way because they are simply too long and with too much noise for my taste.

Not a big deal but was written by Barbara Oakley (woman) "As a young woman with a yen for learning language and no money or skills to speak of ..."

Her on line course: "Learning how to learn" is the most successful MOOC of all time: https://www.coursera.org/learn/learning-how-to-learn

I really enjoyed following it.

My latest hack is to return to paper and pencil. After going paperless about a decade ago, re-wiring these particular neural pathways is quite an obstacle in itself. But in terms of retention and creative flow it is unparalleled. I bring it up because I think the foundation for the memorization and repetition feedback cycle begins with elementary school lessons in handwriting, cursive, the alphabet and spelling. And then onto basic arithmetic and mathematics. The idea that "digital native" students would eschew hours of rote hand writing practice altogether puts humanity in danger of losing something elemental.

I agree with a lot of what she is saying, but two points: 1) The basic solution outlined is 'do a lot of work'. Which is kind of a no brainer, you will learn if you do a lot of work. The tension is how do you get the most productive learning out of the time that the student has 2) The US only recently moved from memorization and rote learning to focus on understanding for a reason. The reason ultimately is the studen…

Do they excel under the current one?

Everyone has their own roadblocks when it comes to learning. Looking at my understanding of programming I realize I have put too much an effort on self-study (rote memorization) and not enough emphasis on interaction (especially with people).

As a child I was always able to memorize something- whether it be classical music, or formulas. However, the deeper connections in learning that allow you to proceed outside of your box come from something else. True understanding is greater than the sum of it's parts.

I like the adage- see one, do one, teach one. Memorization is a requisite for all of them, but true understanding and mastery comes when you're able to take abstract concepts and impart them to other people.

No matter where you are the easiest way to benchmark your competency is to share it with someone else. They don't even need to be an expert, after all- it doesn't take a air traffic controller to see that a plane's landing gear isn't down.

The author is arguing that 'the latest wave of educational reform in mathematics' (in the U.S.) is overemphasizing conceptual understanding, and that doing so will be damaging to students. The author advocates instead using a memorization and repetition based approach. I can see where she's coming from, but the argument she is making is flawed. She describes a process for developing fluency both in foreign language a…

Didn't this turn out a bit of a straw man? As far as I understand, she advocates an understanding of the concepts complemented by some appropriate type of repetition.

There is also a third concept: That of imagining. She speaks specifically of one equation in classical mechanics, which she played around with in her mind until it became second nature.

Of course, this is based on her experience. It appeals to me based on my own experience, yet it isn't a showcasing of scientific rigour within pedagogics.

Author makes the point that repetition of a solid foundation is a necessary condition to reach unconscious mastery of some craft/skill. I am just not sure it is sufficient. Age/talent/nature do play a big factor. Also I suspect starting to learn serious math at age of 26 she is an outlier. Russian is my 2nd language (English is my 3rd) and both I learned through repetition via reading prodigious amounts in each langu…

I learned to read French with the book French for Reading. Perhaps the German version would help you. https://smile.amazon.com/German-Reading-Second-John-Wendel/d...

Thanks for the TL;DR the topic was interesting but I was tired for read more after all day. My grandma used to say "brain is a muscle". And I used to see it as an over-simplification, because I was studying, etc... With the time, I've come to a similar conclusion, a different muscle, and with a micro-services architecture, but at the end of the day, it inherits the attributes, methods and behavior, of the "muscle" cl…

> at the end of the day, it inherits the attributes, methods and behavior, of the "muscle" class

Really, it inherits from the general "biological system" class, of which "muscle" is the common subclass referenced, since it's the one most people have familiarity in utilizing.

The differentiation of "muscle" from other "biological system" classes is entirely unrelated to the "use-it-or-lose-it" feature, however, and your subclassing is inappropriate.

While this seems like being pedantic, I'd argue it's important to know when we're using a member to exemplify a class versus when we're talking about the definition of a class.

The same use-it-or-lose-it applies to everything from lung capacity to stomach size to hormone production by organs, and is a good principle to know about how biology works. The emphasis on "muscle" as the class (rather than an exemplifying member) hides this underlying truth about all biological systems -- that they dynamically adapt to efficiency.

While I tend to agree with the thesis, personal anecdote does not make a valid conclusion.

We probably have decent research on this at this point. Anybody versed in it weighing it?

> You'd be wasting your time trying to get a deep understanding of the Russian phrase, but there's a reason to do it with the mathematical phrase.

I think you're simply wrong here.

You're not talking about the amount of conceptual depth underlying it, you're talking about the relative delta in the conceptual structures between languages you already know and the language you're learning.

On the whole, the Russian phrase has greater conceptual depth; however, Russian is closer to English than mathematics is, and thus you get greater conceptual transfer between your knowledge of English and Russian than your knowledge of English and mathematics, so more of your past experience remains relevant.

In essence, I have something like 36-72k hours considering semantically equivalent statements to the Russian one in English, while I have something like 5-10k hours of studying mathematical statements at all.

Your comment just amounts to saying that having 6x as much practice at task A as task B makes task A relatively easier, which, while true, isn't perhaps as profound as you'd meant it.

Consider this: the entire field of academic inquiry containing Euler's identity is fundamentally an effort to fully understand "I went to the store".
