Notice: I’ve an in depth article detailing how you can use the Feynman Method that may be learn in its entirety right here: The way to Use the Feynman Method to Turn into an Skilled within the Most Difficult Ideas in Knowledge Science.
The Feynman Method was developed by Nobel-Prize-winning physicist Richard Feynman, a pioneer within the area of quantum computing and nanotechnology, who was referred to as the “Nice Explainer” for the good lectures he delivered at Cornell and Caltech.
The Feynman Method is a four-step course of for understanding any subject that works by growing true comprehension of a subject by lively studying.
The Feynman Method may be damaged into 4 steps which might be accomplished in sequence for a given subject:
- Select an idea to be taught: Write down every part you already know a couple of subject utilizing your personal phrases and brainpower. Make a remark of any level the place you could use a protracted difficult phrase to clarify one thing and decide whether or not or not you perceive what the phrase means. If you happen to can clarify what the phrase means in easy phrases, nice! If not, research the phrase and its utilization to be taught extra deeply what it means after which strive to determine a method to describe the phrase utilizing easy language.
- Train it to your self or another person: Instructing an idea to another person actually determines whether or not or not you perceive the idea your self. It’s very laborious to trick your self into believing that you’re an professional on a subject when you possibly can’t train it coherently to another person! The bottom line is to show the idea in such a approach {that a} 10-year-old might perceive it.
- Determine your information gaps and return to the supply materials: After trying to show the idea to another person, it is possible for you to to establish gaps in your information primarily based on the convenience with which you had been in a position to clarify the subject, and whether or not or not you had been in a position to reply any follow-up questions. When you’ve recognized and crammed any gaps, it’s time to return and train the idea to somebody once more. This step is a part of an iterative cycle with Step 2. This cycle needs to be accomplished as many instances as is critical till you already know the subject forwards and backward.
- Simplify your clarification: The ultimate step within the course of includes re-working your clarification in order that it excludes jargon and makes use of straightforward analogies which might be simple to recall and clarify sooner or later. This step forces you to simplify the idea till it may be understood totally by anybody.
What this method is sweet for:
Understanding the hyperlink between theoretical, technical, and mathematical ideas.
How you need to use it to check information science:
The Feynmann Method is a good way to deeply be taught the hardest ideas of information science as a result of it forces you to know them to the purpose the place you would clarify them to anybody. For instance, unsupervised studying or descriptive fashions are ideas of machine studying that may be difficult to know as a result of there is no such thing as a precise goal. Nonetheless, studying how you can clarify how unsupervised studying works and understanding in what eventualities descriptive fashions may be helpful to a primary stage may also help you higher perceive them in a easy approach. Then, if the time ever got here so that you can implement a descriptive mannequin, you’ll perceive within the easiest method the way it ought to work and the outcome it is best to yield.
The SQR3 methodology is a “studying comprehension methodology named for its 5 steps: survey, query, learn, recite, and evaluate”.
The objective of the SQR3 methodology is to assemble and keep in mind as a lot info as potential from what you learn. Studying is one thing you’ll doubtless be doing loads when studying the tougher ideas in information science. Due to this fact, you would possibly as effectively be sure that you’re getting what you got here for.

The Leitner System was developed again in 1972 by German science journalist Sebastian Leitner.
The Leitner System is a research methodology that “makes use of flashcards, card packing containers, and a spaced repetition scheduling system” that has been proven to enhance studying and memorization. This methodology was one of many first research methods to make use of spaced repetition and has held on since with growing reputation as many research have confirmed its effectiveness. This methodology additionally includes lively recall, and may subsequently be thought-about a hybrid between each research strategies (individually mentioned above).
The system makes use of three flashcard packing containers to facilitate spaced repetition:
- Field 1: incorporates new flashcards which might be newly added and flashcards from field 2 that had been answered incorrectly. Flashcards in field 1 are reviewed daily.
- Field 2: incorporates flashcards from field 1 that had been answered appropriately and flashcards from field 3 that had been answered incorrectly. Flashcards in field 2 are reviewed each different day.
- Field 3: incorporates flashcards from field 2 that had been answered appropriately and flashcards from field 3 that had been answered appropriately (no adjustments). Flashcards in field 3 are reviewed as soon as per week.
As you possibly can see, the methodology is similar as spaced repetition that was described earlier and in addition makes use of the facet of lively recall to find out whether or not an idea must be revisited extra often or much less often.
Whereas writing flashcards by hand may be time-consuming, digital flashcard instruments reminiscent of Anki have modernized and sped up the method significantly.
