Effective learning: Twenty rules of formulating knowledge

👇🏼 Thread
1. Do not learn if you do not understand

If you have yet to comprehend something, you are wasting your time trying to learn it.
2. Learn before you memorize

Understand the whole picture before you spend time memorizing individual facts or rules.
3. Build upon the basics

The cost to memorize these things is low, but the payoff is high.
4. Stick to the minimum information principle

Simple is easy. Repetition of simple items is easier to get through.
5. Cloze deletion is easy and effective

This is where you fill in the gap in a sentence. It's quick and effective.

6. Use imagery

It's easier for our brains to store a memory when it can be attached to something visual.
7. Use mnemonic techniques

They help you remember things easier.

8. Graphic deletion is as good as cloze deletion

Instead of filling in a missing word, you fill in a missing piece of an image.

9. Avoid sets

A set is a collection or group of objects i.e. a set of fruits.

It's more difficult to retain memories based on sets (unless it's in the same order every time).
10. Avoid enumerations

These are hard to learn. Better than sets, but still difficult. Instead, break them into small chunks.
11. Combat interference

i.e. trying to learn the difference between historic and historical

It's easy to get these confused. Try to avoid this if you can.
12. Optimize wording

You want to be able to recall the information in the shortest amount of time. This can
- reduce error rates
- increase specificity
- reduce response time
- improve concentration
13. Refer to other memories

It's easy to remember things when you relate it to what you already know. A common example is associating two people with the same name — one person you already know and a new person.
14. Personalize and provide examples

Connect it to your personal life. It will save you time and be easier to recall.
15. Rely on emotional states

Things that are vivid and shocking are easier to retrieve. If it evokes strong emotions, it will be easier to remember.
16. Context cues simplify wording

If the information is specific to a context, it will spark the memory faster.
17. Redundancy does not contract minimum information principle

It may seem redundant to have 3 situations for learning one concept. However, you can keep all 3 simple and as long as they make meaningfully help you learn that thing, they are valid.
18. Provide sources

There may come a time when you want to back up the knowledge with data. Keep sources around just in case. Plus you can revisit later to dive deeper.
19. Provide date stamping

Information may go out of date (depending on what you're learning) so be sure to keep a date around. You may need to update your information in the future.
20. Prioritize

It's easy to say over-consume information and tell yourself you'll need it all in the future. Instead prioritize what you need to know to accomplish your near-term goals.
