What to write down when you’re reading to learn

"Write down anything taking up mental RAM" is the sagest advice
- _emacsomancer_ 6y ago
  And this seems like a place where (at least at some point) getting the notes into a place like org-mode where they could be assigned appropriate labels could be useful: something taking up mental RAM might not be fully tied to the thing you're reading.
UnpossibleJim 6y ago
To be totally honest, I have two separate note taking forms. One when I'm reading the first time through, which I could almost certainly not refer to in any form, as they are scribbled down and unintelligible. The second (and often on my second reading), I have much less comprehension from the reading, I'm taking notes to refer to.
- tartoran 6y ago
  So you immerse and get the idea while skipping on the details and then you address the details. I will try this. I find that I usually go full force, get the idea then rarely come back to notes if I take any. It’s a bad habit that makes me a very poor communicator because I missing the labels. If I undwrstand something thoroughly that can form a metaphor, I can play with it in my head which kindof helps cement the idea. Similarly, for programming I understand comcepts better by playing with some code rather than dryly following line by line on the text. I think it depends on the book, I found myself reading form SICP without much interruption. It’s a certain pace that I enjoy

>The single most helpful thing in figuring out what to write down was noticing when my reading was slowing down (...) > If I have one piece of advice, it’s “learn to recognize the subtle drag of something requiring your attention.” This really resonated with me, but perhaps not in the exact same way as the author. I've recently become more consciously aware of how I react when reading more complex text or parsing more complex points. I read along at a fairly constant speed, not having much trouble following the author's mental model. But at some point the complexity seems to grow beyond what I can comfortably hold in my head without stopping and really trying to parse what's on the page in front of me. I can react to this difficulty in two ways: 1. I let the inertia carry me past the sentence, not really grokking it, instead it becomes a sort of buzz in my mental model (or a 'drag' in the author's words), something like step 2 in south park's famous step 1: do something - step 2: ??? - step 3: profit. I continue on with the text, but now my understanding of it is compromised. 2. I recognize what I'm doing, stop reading, and start re-reading the sentence much more slowly. Look at the surrounding text for illuminating context (sometimes this snag isn't because it's an overly complex point, it's just a poorly structured sentence and the next line clears it up). I may need to start taking notes to parse it. My problem is I'm quite lazy (and I'm usually reading in bed to relax) and tend to default to strategy 1. But I'm trying to change that bad habit and react with strategy 2.

  It’s only a bad habit if you don’t go back later and make sure you grok it. Reading through can give you an understand of the larger picture of what the author is saying which can help you when you go back and re-read the part that you stumbled on. This might be especially true if you feel like it’s a point where it’s gotten too unwieldy or complex. That may be a sign you don’t yet have the necessary basis or metaphor for the idea as presented.
  - rablackburn 6y ago
    There definitely seems to be a balancing act between: * stopping all progress until you fully understand the point * continue moving forward so you don't get stuck and give up Interestingly I've found that leaning towards 'just keep going' seems to be more effective when learning a second language. Whereas slowing down and doing some background reading helps much more with technical topics. Language seems much more natural to learn from pure exposure. So easy a baby can do it :)

The best information on this topic I’ve come across is contained in Mortimer Adler’s “How to read a book”. Highly recommended if you’re doing any non-fiction reading.

  Here [0] you can find a decent summary of the book. For me the single most important point that the book taught me was that it's ok to write in books, they don't have to be in pristine condition without any text in them. The white pages in books are meant specifically to write on. They explain this point of the book in a separate blog post [1] for some reason. Anyway... I never used to write in books, now this has become a central part of my learning process. The physical act of scribbling a question mark next to unclear parts, rephrasing what is meant and so on has helped me understand complex material faster as well as made it easier to refer to at a later point (as there is no need to worry about any notes getting lost).

Write down anything that seemed surprising or otherwise non-obvious on first reading. Even better: rewrite the surprising parts in your own words, once you have understood them, in a way that clearly explains to you that which you originally found puzzling, with enough context that you will get the point when you re-read your notes (note that this helps even if you never re-read these notes, because the act of paraphrasing is helpful on its own.)
jldugger 6y ago
> Writing down a thing you’ve read (/heard/etc) improves your memory and understanding, at the cost of disrupting the flow of reading. Flow disruption, in the case of self-paced learning, is likely a good thing, even though it feels like it's slowing you down. Even though it _is_ slowing you down. The act of getting back into the flow requires some level of retrieval from long term memory, and retrieval is practice at remembering. So anything that helps you practice remembering what you just read is useful, and anything that helps you read more pages per hour but does nothing to change how much you remember per hour is wasteful.

Does anyone use LCD drawing tablets for taking notes? I don't like using paper that much, and for anything important I prefer to have it digitized so that information can be sorted, copied, and recalled. I wonder how important it is to be able to come back to those notes, or if simply writing them down and never coming back to them would be enough. In that case, a "dumb" LCD writing pad such as the Boogie Board would be enough. I'm not sure if I want to hassle with a more expensive and complex system such as a drawing tablet, which would be an alternative.

References. Seriously. I read a lot and I would completely drown if I was taking notes of anything that I am interested with. The only thing I really want to note is my own index system where I have a document with keywords and list of links, books, documents, other resources where I have seen this thing. Rarely a small note -- once I find the reference I am usually able to recall what the reference was about. I have two types of reference stores. 1. My global index. This is one bag of huge amount of keywords and links. The storage works like this: I enter the reference (which is basically any free text, usually a link). I enter a number of words, terms I might be trying to look it up in the future, name of context I am researching this reference for (for example name of project I am working on atm). Later when I don't remember the reference I may be able to recall I have worked on some particular project and use the name of the project to help me find the reference. 2. My project index. This is typically a document listing design/decision details I made for a particular project with references to materials. For example, I might have decided to use a particular board component and then have a reference to digikey/mouser part, reference to specs, reference to any number of designs I found on the internet that include the part, etc.
raxxorrax 6y ago
First round of reading about a topic I don't write down anything because of flow-problems the author mentioned. It also helps with getting a view beyond the horizon. Then I try to write a good summary. Writing something really helps with memorizing. Curiously, I think the effect is much weaker when typing something on a machine. Rereading my summary gives me an impression of how well I understood a topic. If it is just incoherent rumblings, I probably should revisit the topics in question. So it can also be a good self test. Such an iterative approach takes time though...

hliyan 6y ago
I always used to tell myself "You can never be sure you've really understood something until you try to recreate it". It started from my university days when I noticed that stuff I read and thought "yeah I got this" later turned out to be anything but, when I had to do it without the textbook at hand. Since then, I've always kept the habit. There's literally a pen and notepad two inches to the right of my keyboard. There is also a terminal open always, where I can do this: $ learned > about Walder's law: the bulk of discussion on programming language > design centers on syntax (which, for purposes of the argument, is > considered a solved problem), as opposed to semantics. That's an actual example from two days ago. "learned" is just a shell script: #!/bin/bash read text echo -e "\n$text" >> ~/Dropbox/writing/notes/learned.txt As you can see it auto syncs to dropbox.
- j0hnml 6y ago
  That’s a really simple but great idea. Thank you for that. I can’t tell you how many times I’ve learned something while working but have been too lazy to find my notes and figure out which note to put it in. And so I never end up making a note of it in the first place.
Deviate 6y ago
The answer depends on what you're trying to learn and for what purpose, as it will dictate what learning strategies you utilize. For example, if you're studying to retain information for educational purposes (and reproduce in an exam environment) then research has indicated that reading and rereading have the lowest utility (return on time invested) in the 10 common strategies used by students. The strategy offering the highest utility was practice testing under exam conditions. If you are reading to learn about a topic that requires you to retain information in a sequential manner, then using learning techniques such as a memory palace can be helpful. This is a technique that allows you to picture a room you know very well and associate blocks of information with objects in that room while you are learning. It's a very common way to deal with performance anxiety which manifests as blank memory. I'm happy to share some thoughts on potential approaches if you offer some clarity on what your desired outcome is.
