20 Golden Rules for Effective Learning: A Practical Guide to Building Knowledge Systems
Differences in learning efficiency rarely depend on innate intelligence but rather on how knowledge is organized. Mastering proper learning methods can multiply your efficiency several times over. The following 20 golden rules form the core foundation for building an effective knowledge system, presented in order of importance. The earlier rules help you avoid common pitfalls and yield greater benefits. These principles work particularly well with spaced repetition tools like Anki and SuperMemo to maximize your learning outcomes.
Core Principles: Making Memory Simpler
The first 16 rules revolve around a central goal: transforming complex knowledge into simple, memorable forms that reduce memory burden while improving retention efficiency.
1. Don’t Memorize Before Understanding
This is the most important rule of all. Trying to memorize content you don’t understand is essentially wasted effort. It’s like someone who doesn’t understand German trying to memorize a German history book—even if they could recite the entire text, they wouldn’t truly comprehend the historical events, and the process would consume enormous time.
In daily learning, we often resort to superficial memorization due to obscure textbooks or time constraints. This approach is not only inefficient but also results in knowledge that can’t be applied or reasoned with. You must first invest time in understanding the context, causes, and consequences of concepts before memorizing related details.
Action Guide: Immediately pause when encountering unfamiliar content.彻底弄懂 it through research, video tutorials, or consulting teachers. Don’t hope that “memorizing first and understanding later” will work.
2. Learn First, Then Memorize
Before memorizing scattered知识点, you need to establish a “big picture view.” Imagine trying to complete a jigsaw puzzle without looking at the reference image—it would be extremely difficult. Similarly, you should first skim relevant chapters to grasp the overall knowledge framework (such as “basic principles of internal combustion engines”), form a simple mental model, then create specific question-answer cards for key details within that framework (like “What pushes the piston in an internal combustion engine?”). This way, each知识点 is no longer isolated but organized and connected, making memory more efficient.
Action Guide: Avoid getting bogged down in details initially. First quickly浏览材料 to grasp the overall structure and core ideas of the topic, then gradually delve deeper into learning and memorizing specific content.
3. Start with Basics and Progress Step by Step
The “big picture view” or “knowledge framework” mentioned in the second rule should start as simply as possible. Don’t attempt to master complex, detailed models all at once; instead, begin with the most simplified version and gradually build upon it.
Never underestimate foundational knowledge. Even if it seems obvious, it’s worth investing time to memorize. Basic concepts form the building blocks of complex knowledge—forgetting one foundational concept can cause an entire knowledge system to collapse. The cost of memorizing basics is extremely low, usually requiring just a few reviews to remember permanently. In contrast, you might spend 50% of your learning time tackling the most difficult 3-5% of knowledge. Investing more time in fundamentals is definitely a high-return investment.
Action Guide: Regardless of the new field you’re learning, start with the most core, basic concepts. Ensure you have a thorough grasp of these fundamentals before moving on to more advanced content.
4. Adhere to the “Minimum Information Principle”
This is the core technique for simplifying complex knowledge: each memory card should contain only one piece of minimized information whenever possible.
Why is simplicity better for memory?
-
Single Pathway: When memorizing simple知识点, the neural pathways activated in the brain during each recall are nearly consistent—like repeatedly traveling the same road, which becomes increasingly clear. With complex知识点, the pathways activated during each recall may vary, causing information interference and making it difficult to consolidate memories.
-
Precise Review: If a card contains two知识点—A (simple) and B (difficult)—you’d have to review the entire card at B’s required frequency to remember B, wasting time on reviewing A. When separated, A and B can be reviewed at their optimal intervals, significantly saving time.
Poor Example (complex):
Q: What are the characteristics of the Dead Sea?
A: The Dead Sea is a salt lake on the border between Israel and Jordan. Its coastline is the lowest point on Earth (-396 meters), it is 74 kilometers long, its salt content is 7 times that of the ocean (30%), its high density allows people to float, and only simple organisms can survive due to its high salinity.
Excellent Example (after splitting):
Q: Where is the Dead Sea located? A: On the border between Israel and Jordan.
Q: What is the lowest point on Earth’s surface? A: The coastline of the Dead Sea.
Q: What is the approximate elevation of the Dead Sea? A: 400 meters below sea level.
Q: How many times saltier is the Dead Sea compared to the ocean? A: 7 times.
Q: Why can people float in the Dead Sea? A: Because of its high salt content (high density).
Q: Why is the Dead Sea called “dead”? A: Because its high salinity prevents most organisms from surviving.
The split questions and answers are very concise, minimizing the amount of information retrieved from the brain during each recall. In the long run, the simpler the知识点, the better the memory效果.
5. Cloze Deletion: Simple and Effective
If you find it challenging to follow the Minimum Information Principle, you can use the “Cloze Deletion” technique. This powerful tool quickly converts textbook knowledge into memory cards by removing关键词 and asking you to fill in the blanks.
Example:
Original sentence: “In 1991, Apple and IBM jointly invested $40 million to establish Kaleida Labs, aiming to create a multimedia programming language called Script X.”
Possible cloze deletion cards:
Q: In 1991, … and IBM jointly invested 40 million
Q: In …, Apple and IBM jointly invested $40 million to establish Kaleida Labs. A: 1991
Q: Kaleida Labs aimed to create a multimedia programming language called …. A: Script X
This method easily extracts multiple知识点 from a single paragraph that comply with the Minimum Information Principle.
6. Make Good Use of Images
The human brain’s visual processing能力 far exceeds its language processing能力—”a picture is worth a thousand words” has scientific basis. Images contain details and information that can often be remembered effortlessly. In fields like anatomy, geography, chemistry, and history, skillful use of images can significantly reduce learning time.
The popularity of mind maps stems from their utilization of the brain’s powerful memory能力 for images and spatial relationships.
Action Guide: When creating cards, ask yourself “Can this知识点 be represented with an image?” Whenever possible, use images.
7. Utilize Mnemonic Techniques
Mnemonic techniques are various methods that make memory easier, such as homophones, storytelling, and acronyms. These techniques are highly effective—ordinary people can learn to remember the order of a deck of cards with training.
But remember: mnemonic techniques solve the problem of “quick memorization,” while the real bottleneck in learning is “long-term retention.” Achieving long-term memory still requires spaced repetition. However, during the initial learning phase, especially when dealing with dry information, mnemonic techniques are valuable aids. With practice, using mnemonics will gradually become an automatic habit.
8. Image Cloze Deletion
Similar to text cloze deletion, image cloze deletion (Graphic Deletion) covers part of an image and asks you to recall the covered content. This is extremely effective for learning subjects that require identifying locations and components.
Examples:
-
Anatomy: Cover the “humerus” on a human skeleton diagram and ask “What is this bone?” -
Geography: Cover Brazil on a world map and ask “Which country is this?”
A single image can generate dozens of different cards, each questioning a different part, making this method highly efficient.
9. Avoid Sets
A set is a collection of unordered content, such as “List all member states of the European Union.” This type of question is difficult to remember because the order in which items appear in your mind during each recall may vary, severely interfering with memory consolidation.
Solution: Convert unordered sets into ordered lists (Enumeration), such as memorizing EU countries in the order they joined.
Poor Example (set):
Q: What are the member states of the European Union (as of 2002)?
A: (List of 15 country names)
Excellent Example (converted to chronological sequence):
Q: Besides France, which countries joined the European Coal and Steel Community in 1952? A: Germany, Italy, and the Benelux countries.
Q: Which three countries joined the European Community in 1973? A: The United Kingdom, Ireland, and Denmark.
… and so on.
This approach not only breaks down large sets into smaller questions but also incidentally teaches the history of EU expansion, creating meaningful connections between知识点.
10. Avoid Long Lists
While lists (Enumeration) are better than sets, excessively long lists remain memory challenges—like memorizing long poems or lengthy chemical processes.
Solution: Use overlapping cloze deletion for breakdown.
Example for learning the alphabet:
Q: What are the first three letters of the alphabet? A: A B C
Q: Fill in the missing letters: A … C … E A: B, D
Q: Fill in the missing letters: B … D … F A: C, E
…
This way, you only need to focus on small segments at a time rather than the entire lengthy list. After reviewing small segments, reciting the entire sequence will feel much easier. The same applies to memorizing poems—if you总是 get stuck on a particular line, create cloze deletion cards for that line with its上下文.
11. Combat Memory Interference
When learning two similar pieces of content, they easily “interfere” with each other, causing confusion. For example, confusing “historic” (having historical significance) with “historical” (related to history) is one of the main causes of forgetting.
Interference is difficult to predict, so it’s best to proactively prevent and eliminate it before it causes significant problems.
Coping Strategies:
-
Make知识点 more distinct: Use examples, images, and personal experiences to differentiate similar concepts. -
Follow the Minimum Information Principle: Simpler知识点 are less likely to be confused with other information. -
Eliminate immediately: Once you发现 confusion between two知识点, immediately create dedicated cards to compare and distinguish them—don’t delay.
12. Optimize Wording
The wording of questions on your cards should act like precise keys that immediately unlock the correct “lock” in your brain. Wording must be concise, clear, and directly focused on the core.
Poor Example (wordy):
Q: In 1985, Aldus Corporation pioneered desktop publishing with PageMaker. Later, which Denver-based company surpassed it due to its failure to innovate?
A: Quark
Excellent Example (concise):
Q: Which company surpassed PageMaker in desktop publishing after it failed to innovate?
A: Quark
Even Better Example:
Q: Who surpassed PageMaker in the market?
A: Quark
Remove all unnecessary background information that only slows down response time or creates interference. If other information is important, create separate cards for it.
13. Connect to Other Memories
Linking new knowledge to existing content significantly enhances memory. This provides context for new information, reduces interference, and makes it easier for your brain to “accept” it.
Example (learning the word “cringing”):
-
Poor question: (Negative term) Describing the act of shamelessly acknowledging one’s shortcomings and begging. -
Good question: (Negative term) Describing a shamelessly humble and supplicant manner.
If you already know “humble” and “supplicant,” using them to explain “cringing” helps you lock onto the new word’s meaning faster and more accurately.
14. Personalize and Provide Examples
Connecting knowledge to your personal life is one of the most effective memory techniques. Personal experiences are unique and provide powerful memory anchors.
Example (learning the word “divan”):
-
Poor question: What do you call a soft couch without arms or a backrest? -
Good question: What do you call that soft couch without arms or a backrest (like the one at your friend John’s place)?
If you have a clear image of John’s couch, this personalized example will be much easier to remember than any abstract definition.
15. Leverage Emotional States
Emotions significantly enhance memory. Examples that evoke strong feelings (joy, surprise, sadness, or anger) make知识点 more “unforgettable.”
Example (learning the word “banter”):
-
Poor question: A type of light, playful conversation. -
Good question: Describing that light, playful conversation (like the dialogue between characters in that comedy movie you watched).
Vivid, emotionally charged examples help you concretize abstract concepts, reducing learning time by several times.
16. Use Contextual Cues
Add simple “tags” or “prefixes” to知识点 to tell your brain which domain they belong to. This helps your brain quickly enter the correct “thinking channel” and avoid confusion.
Example: The acronym “GRE” can refer to the “Graduate Record Examination,” but has a different meaning in biochemistry.
-
Poor question: In biochemistry, what does GRE stand for? -
Good question: Biochem: GRE
The “Biochem:” prefix acts like a switch, instantly adjusting your thinking to the biochemistry context, preventing you from first thinking of “graduate exams” and thereby reducing response time and interference.
Advanced Principles: Optimization and Management
The next 4 rules focus on optimizing and managing your knowledge system, helping you more efficiently maintain and utilize learned knowledge.
17. Appropriate Redundancy is Necessary
The “Minimum Information Principle” doesn’t mean “minimum amount of information.” In some cases, appropriate repetition and supplementation are necessary.
-
Active vs. Passive Memory: When learning a foreign language, you need both passive recognition (“see English, say Chinese”) and active recall (“see Chinese, say English”). Therefore, both “phone -> telefono” and “telefono -> phone” cards are necessary.
-
Supplement Reasoning Processes: When learning mathematical problem-solving methods, answers can include key reasoning steps. This isn’t rote memorization but ensures you follow the correct logical path each time.
-
Multi-angle Understanding: For extremely important concepts, creating memory questions from different angles deepens understanding and ensures you can recall them in any situation.
18. Note Sources
Documenting sources for learned knowledge proves invaluable later. When you发现 conflicting information from different sources, you can trace back to evaluate reliability. Sources also provide references when deeper research is needed or when you need to prove information to others. Source information serves as reference and generally doesn’t need to be memorized.
19. Label Dates
Knowledge has an expiration date. Economic data, technological knowledge, personal statistics, and other information change over time. Adding dates or version numbers to these知识点 reminds you they might be outdated and need updating.
20. Clarify Priorities
You can never learn everything you want to know, so distinguishing priorities is crucial. Prioritization runs through the entire learning process:
-
Source Selection: Decide which books, articles, or courses are most important to you. -
Knowledge Extraction: Choose the most valuable parts from materials to learn. -
Knowledge Organization: You can first import large amounts of material into learning tools, then process and optimize them into memory cards according to priority. -
Review Process: Use learning tool features to handle particularly important or updated knowledge specially (such as early review, re-memorization, frequency adjustment, etc.), and ignore or delete knowledge that’s no longer important or incorrect.
The key to productive learning lies not just in effort but in wisely allocating time and energy.
