Article - The Difference Between Memorizing and Understanding
This article continues your student learning-skills series, focusing on why understanding produces deeper and more transferable learning than memorization alone.
The Difference Between Memorizing and Understanding
Introduction
Imagine two students preparing for the same examination.
Student A spends hours memorizing definitions, formulas, sentences, and answers. The student can remember many things exactly as they appeared in the textbook.
Student B spends time trying to understand what the ideas mean, why they work, and how they connect to other ideas. The student may not remember every sentence word-for-word, but can explain concepts in their own words and use them in new situations.
Both students are learning—but they are learning in very different ways.
This leads to an important question:
Is memorizing the same as understanding?
The answer is no.
Memorization and understanding are both useful, but they serve different purposes. Memorization helps you remember information. Understanding helps you use, explain, connect, analyze, and apply information.
The strongest learners do not choose one and completely reject the other. They know what to memorize, what to understand, and how to combine both.
1. What Is Memorization?
Memorization is the process of storing information in your memory so that you can recall it later.
For example, you might memorize:
Vocabulary meanings
Mathematical formulas
Scientific definitions
Historical dates
Chemical symbols
Grammar rules
Names of countries
Multiplication tables
Important facts
For example:
Water boils at approximately 100°C at standard atmospheric pressure.
You can memorize this fact.
Memorization answers the question:
“Can I remember this information?”
That is useful—but remembering something does not necessarily mean you understand it.
2. What Is Understanding?
Understanding means knowing what something means, how it works, why it happens, and how it connects to other knowledge.
Suppose you know:
Area of a rectangle = length × width
You have memorized a formula.
But if you understand it, you can explain:
What area means
Why length and width are multiplied
How the formula relates to the number of squares inside the rectangle
How to use it when the dimensions change
How to solve a real-life problem involving area
How to check whether your answer makes sense
Understanding answers a deeper question:
“Can I explain and use this knowledge?”
3. Memorizing and Understanding Are Not Enemies
It is important not to misunderstand the difference.
Memorization is not bad.
Understanding is not always enough by itself.
You need some information in your memory before you can use it effectively.
For example, a mathematics student needs to remember basic multiplication facts.
An English learner needs to remember vocabulary.
A chemistry student needs to know chemical symbols.
A musician needs to memorize some musical patterns.
The problem begins when students believe:
“If I can memorize the answer, I understand the subject.”
You can remember an answer without understanding the idea behind it.
The goal is:
Memorize essential information + Understand the ideas + Apply what you know
4. A Simple Example: Mathematics
Consider:
2 × 5 = 10
A student can memorize this fact.
But understanding means knowing that:
2 × 5 represents two groups of five, or five groups of two.
You can also see it as:
5 + 5 = 10
or:
2 + 2 + 2 + 2 + 2 = 10
Now the student understands the relationship.
If the question changes to:
“There are 5 boxes containing 2 pencils each. How many pencils are there?”
The student can solve it.
Memorization:
2 × 5 = 10
Understanding:
Multiplication represents repeated groups, so 5 groups of 2 pencils give 10 pencils.
Understanding allows knowledge to transfer to new situations.
5. A Science Example
Imagine a student memorizes:
“Plants need sunlight for photosynthesis.”
The student may be able to repeat the sentence in an examination.
But understanding requires deeper questions:
What is photosynthesis?
Why is light important?
What happens inside the plant?
What materials are needed?
What products are produced?
What happens if light is reduced?
How does photosynthesis relate to plant growth?
Now the student has a mental model instead of a sentence.
Memorization gives you a fact.
Understanding gives you a system of ideas.
6. A History Example
Suppose you memorize:
“A historical event happened in 1945.”
That may help you answer a basic question.
But understanding history requires asking:
What happened?
Why did it happen?
Who was involved?
What conditions existed before it?
What were the consequences?
How did it affect later events?
What different perspectives exist?
Memorizing a date gives you one piece of information.
Understanding the historical event helps you see the cause-and-effect relationships.
7. Memorization Is About Recall
A useful way to understand the difference is:
Memorization focuses on:
Recall
“Can I remember it?”
Understanding focuses on:
Meaning
“Can I explain it?”
Application focuses on:
Use
“Can I use it?”
Analysis focuses on:
Relationships
“Can I compare, connect, or evaluate it?”
These are different levels of learning.
8. The Problem With Rote Learning
Rote learning means learning something mainly through repetition without necessarily understanding its meaning.
For example:
A student memorizes:
“Photosynthesis is the process by which green plants make food.”
The student can repeat the definition.
But when asked:
“Why do plants need sunlight?”
the student cannot explain.
The memorized sentence has not become useful knowledge.
Rote learning can help with certain basic facts, but if it becomes the main learning strategy, students may struggle with unfamiliar questions.
9. Why Memorized Answers Can Fail in Exams
Imagine a student memorizes the exact answer from a textbook.
Then the teacher changes the question.
Instead of:
“Define evaporation.”
the question becomes:
“Explain how evaporation helps cool a wet surface.”
The student may struggle.
Why?
Because the student memorized the definition but did not understand the process.
A student who understands evaporation can reason:
Liquid molecules gain energy → some escape from the surface → higher-energy molecules leave → the remaining liquid loses energy → cooling occurs.
Understanding makes it possible to answer questions that are asked in different ways.
10. Understanding Helps You Handle New Problems
Real learning becomes valuable when you can use knowledge in unfamiliar situations.
Suppose you memorize:
Force = mass × acceleration
That's useful.
But understanding allows you to think:
What happens if mass increases?
What happens if acceleration decreases?
Why does a heavier object require more force for the same acceleration?
How could this principle apply to vehicles?
Can I rearrange the formula to find mass?
Can I interpret the units?
Now the formula becomes a tool for thinking.
11. Understanding Creates Connections
Knowledge becomes stronger when new information connects with what you already know.
For example:
Photosynthesis
connects to:
→ Plants
→ Sunlight
→ Carbon dioxide
→ Oxygen
→ Glucose
→ Energy
→ Food chains
→ Ecosystems
→ Respiration
Instead of remembering isolated facts, you create a network of knowledge.
The more meaningful connections you make, the easier it becomes to retrieve and use information.
12. Ask “Why?”
One of the simplest ways to move from memorization to understanding is to ask:
Why?
Instead of memorizing:
“The sky appears blue.”
Ask:
“Why does the sky appear blue?”
Then investigate.
You discover that sunlight contains different wavelengths and that Earth's atmosphere scatters shorter wavelengths more strongly.
Now you don't just remember a fact.
You understand a mechanism.
Make “Why?” one of your most useful learning questions.
13. Ask “How?”
Another powerful question is:
How does it work?
For example:
Instead of memorizing:
“Exercise improves health.”
Ask:
“How does exercise affect the body?”
You can explore:
Heart function
Blood circulation
Muscles
Energy use
Sleep
Mood
Brain function
“How?” turns a simple statement into an investigation.
14. Explain It in Your Own Words
One of the best tests of understanding is simple:
Close the textbook and explain the idea in your own words.
Don't copy the textbook.
Imagine you are teaching a younger student.
For example:
Instead of memorizing:
“Photosynthesis is the process by which green plants convert light energy into chemical energy.”
You might explain:
“Plants use light energy to help turn water and carbon dioxide into food, while oxygen is released.”
Your explanation doesn't have to use exactly the same words as the textbook.
If you can explain the concept accurately in simple language, you probably understand it better.
15. Use the Feynman Technique
The Feynman Technique is a simple learning method based on explaining an idea as clearly as possible.
Step 1: Choose a concept
For example:
Newton's laws.
Step 2: Explain it simply
Pretend you are teaching a younger student.
Step 3: Find the gaps
Where did you become confused?
Step 4: Review
Return to the textbook or lesson and study the confusing part.
Step 5: Explain again
Make your explanation simpler and clearer.
The process is:
Learn → Explain → Find gaps → Review → Explain again
This exposes the difference between thinking you understand and actually understanding.
16. Use Examples
Examples help transform abstract information into something concrete.
Suppose you learn:
“A noun is a word that names a person, place, thing, or idea.”
Don't stop there.
Find examples:
Person: teacher
Place: school
Thing: book
Idea: happiness
Then create your own sentences.
The teacher opened the book at the school.
Now you are applying the definition.
17. Use Non-Examples
A powerful way to test understanding is to identify what something is not.
For example:
If you are learning nouns, ask:
“Is 'quickly' a noun?”
No.
Why?
Because “quickly” functions as an adverb.
If you understand the concept, you can distinguish between examples and non-examples.
This is stronger than simply memorizing a definition.
18. Compare Similar Ideas
Understanding improves when you compare related concepts.
For example:
Memorization
Remembering information.
Understanding
Knowing what the information means and how it works.
Application
Using the knowledge in a situation.
Analysis
Examining relationships and differences.
Ask:
“How are these ideas similar?”
and:
“How are they different?”
Comparison forces your brain to organize knowledge.
19. Use the Knowledge in a New Situation
A strong test of understanding is transfer.
Suppose you learned about percentages.
Can you use percentages to calculate:
Discounts?
Exam scores?
Profit?
Interest?
Population changes?
Sports statistics?
If you can apply the idea in different situations, you probably understand it.
Learning is stronger when knowledge can travel beyond the original example.
20. Don't Memorize Everything
Trying to memorize every piece of information is inefficient.
Some information is worth memorizing because quick recall is useful.
For example:
Basic arithmetic facts
Common vocabulary
Essential formulas
Chemical symbols
Important terminology
Common grammar patterns
But other information is better learned through understanding.
For example:
Why a scientific process occurs
How a mathematical method works
Why a historical event happened
How an argument is constructed
How a system behaves
Ask:
“Do I need to memorize this, or do I need to understand it?”
That question can save you a lot of study time.
21. Use Memorization After Understanding
A useful strategy is:
First:
Understand the idea.
Then:
Memorize the essential information.
For example, when learning a mathematical formula:
Understand what each variable means.
Understand why the formula works.
See an example.
Solve a problem.
Then memorize the formula for quick recall.
This is usually stronger than memorizing the formula without understanding it.
22. Use Active Recall
Whether you are memorizing or understanding, active recall is powerful.
Instead of repeatedly reading:
“What are the three states of matter?”
Close your book and ask yourself:
“What are the three states of matter?”
Then answer:
Solid, liquid, and gas.
For deeper learning, ask:
“How are they different?”
Now you are combining recall with understanding.
23. Use Practice Questions
Practice questions reveal whether your knowledge is actually usable.
After studying a topic, don't only ask:
“Does this look familiar?”
Ask:
“Can I solve a problem without looking at the answer?”
This is important because familiarity is not the same as mastery.
A textbook page may look familiar because you have read it many times.
But when the book is closed, can you explain the concept?
That's the real test.
24. Teach Someone Else
Teaching is an excellent test of understanding.
Choose a topic and explain it to:
A classmate
A younger student
A family member
Your study group
Even yourself
If they ask:
“Why?”
and you cannot answer, you have found a gap in your understanding.
That gap is valuable.
Now you know what to study next.
25. Build a “Knowledge Tree”
Instead of writing isolated facts, organize them.
For example:
Photosynthesis
What?
Process plants use to make food.
Needs:
→ Light
→ Water
→ Carbon dioxide
→ Chlorophyll
Produces:
→ Glucose
→ Oxygen
Connects to:
→ Plant growth
→ Food chains
→ Energy
→ Respiration
This structure creates relationships between ideas.
The brain remembers meaningful connections better than disconnected information.
26. Watch Out for the “I Know This” Feeling
One of the biggest learning traps is false confidence.
You read the same paragraph five times and think:
“I know this.”
But when the book closes, you cannot explain it.
Why?
Because recognition is easier than recall.
Seeing the answer can create a feeling of familiarity.
True understanding requires you to produce the explanation yourself.
Don't ask:
“Does this look familiar?”
Ask:
“Can I explain it without looking?”
27. Use the Three-Level Learning Test
After studying something, test yourself at three levels.
Level 1 — Recall
What is it?
Level 2 — Explain
How does it work? Why does it matter?
Level 3 — Apply
Can I use it in a new situation?
For example:
Topic: Percentage
Recall:
What is a percentage?
Explain:
How does percentage represent part of a whole?
Apply:
A shirt costs 50,000 MMK and has a 20% discount. What is the sale price?
If you can succeed at all three levels, your learning is becoming much stronger.
28. Different Subjects Need Different Approaches
Not every subject should be studied in exactly the same way.
Mathematics
Understand principles and solve many problems.
Science
Understand processes, causes, evidence, and relationships.
History
Understand chronology, causes, consequences, and perspectives.
English
Understand grammar patterns and practice using them.
Vocabulary
Memorize meanings, but also use words in sentences.
Geography
Understand locations, relationships, and patterns.
Literature
Understand themes, characters, language, and evidence.
The best learners adapt their learning methods to the subject.
29. Memorization vs Understanding
| Memorization | Understanding |
|---|---|
| Focuses on recall | Focuses on meaning |
| Remembers information | Explains information |
| Often uses repetition | Uses connections |
| Can work with isolated facts | Builds a knowledge network |
| Useful for essential facts | Useful for concepts |
| May fail with unfamiliar questions | Helps with new situations |
| Answers “What?” | Answers “Why?” and “How?” |
| Can be temporary | Often produces deeper learning |
| Helps quick recall | Helps application and reasoning |
The strongest learning combines both.
30. The Learning Ladder
Think of learning as a ladder:
1. Memorize
I can remember it.
↓
2. Understand
I can explain it.
↓
3. Apply
I can use it.
↓
4. Analyze
I can break it down and find relationships.
↓
5. Evaluate
I can judge or compare ideas using evidence.
↓
6. Create
I can use what I know to produce something new.
Memorization is not the top of the ladder.
It is often the foundation.
31. A Better Study Method
Instead of:
Read → Read again → Highlight → Read again → Memorize
Try:
Step 1: Preview
Look at the topic and headings.
Step 2: Question
Ask what you want to understand.
Step 3: Learn
Read or listen carefully.
Step 4: Explain
Close the book and explain the idea.
Step 5: Recall
Write or say what you remember.
Step 6: Practice
Solve problems or create examples.
Step 7: Check
Compare your answer with reliable information.
Step 8: Review
Return to the parts you don't understand.
Step 9: Apply
Use the knowledge in a new situation.
This transforms passive study into active learning.
32. A Simple Example of Better Learning
Suppose you need to learn:
The formula for the area of a triangle
Instead of only memorizing:
A = ½bh
Try this:
Understand
A triangle can be viewed as half of a suitable rectangle or parallelogram.
Identify
b = base
h = perpendicular height
Explain
The area is half the base multiplied by the perpendicular height.
Practice
Calculate the area of different triangles.
Apply
Use the formula to calculate the area of a triangular piece of land.
Recall
Finally, memorize:
A = ½bh
Now you have both understanding and recall.
33. The “Why–How–What If?” Method
For deeper learning, ask three questions.
WHY?
Why does this happen?
HOW?
How does it work?
WHAT IF?
What would happen if something changed?
For example:
Topic: Plant growth
Why do plants need sunlight?
How does sunlight contribute to photosynthesis?
What if a plant receives very little light?
These questions move your brain beyond memorization.
34. Use Your Mistakes as Learning Tools
If you make a mistake, don't simply correct the answer.
Ask:
“Why did I make this mistake?”
Maybe you:
Forgot a formula.
Misunderstood the question.
Applied the wrong rule.
Made a calculation error.
Memorized without understanding.
Didn't check your work.
Create a mistake notebook.
For each mistake, write:
My answer → Correct answer → Why I was wrong → What I will do differently
Mistakes can reveal gaps in understanding.
35. The Most Powerful Question
When studying, ask yourself:
“If the question changes, can I still solve it?”
If the answer is yes, you are probably developing understanding.
If the answer is no, you may need to go deeper.
For example, if you memorized:
“The answer is 25.”
but cannot solve a similar problem with different numbers, you memorized a result.
If you understand the method and can solve new versions, you learned the concept.
36. A 20-Minute Understanding Routine
Try this method when learning a new topic.
Minutes 1–3: Preview
Look at the title, headings, diagrams, and key terms.
Minutes 4–8: Learn
Read carefully and identify the main idea.
Minutes 9–11: Close the book
Explain what you learned without looking.
Minutes 12–15: Practice
Answer questions or solve problems.
Minutes 16–17: Find gaps
What couldn't you explain?
Minutes 18–19: Review
Study those weak areas.
Minute 20: Summarize
Write the idea in 2–3 sentences.
This is far more active than simply reading the same page repeatedly.
37. A Student's Learning Formula
Remember:
MEMORIZE → UNDERSTAND → APPLY → CONNECT → EXPLAIN → REVIEW
Memorize
Store essential information.
Understand
Discover meaning.
Apply
Use the knowledge.
Connect
Link it to other ideas.
Explain
Teach it in your own words.
Review
Return to it over time.
This creates stronger and more useful learning.
38. Student Checklist
After studying a topic, ask yourself:
☐ Can I define the key idea?
☐ Can I explain it in my own words?
☐ Can I explain why it works?
☐ Can I explain how it works?
☐ Can I give an example?
☐ Can I give a non-example?
☐ Can I connect it to something I already know?
☐ Can I solve a problem using it?
☐ Can I answer a question without looking at my notes?
☐ Can I teach it to someone else?
☐ Can I use it in a new situation?
☐ Do I know which parts I still don't understand?
If you can answer “yes” to most of these questions, you are moving beyond memorization toward real understanding.
Conclusion
Memorization and understanding are both important parts of learning—but they are not the same.
Memorization helps you remember.
Understanding helps you explain.
Application helps you use.
Analysis helps you think.
Creation helps you produce something new.
You need facts in your memory, but facts become much more powerful when you understand how they connect and how they can be used.
So, instead of asking:
“How can I memorize this faster?”
sometimes ask:
“How can I understand this better?”
Ask why.
Ask how.
Create examples.
Explain ideas in your own words.
Solve unfamiliar problems.
Teach someone else.
Test yourself without looking at the answer.
And when you make a mistake, investigate why.
Remember:
Memorization puts knowledge into your memory. Understanding turns knowledge into a tool.
The goal of education is not simply to remember more information.
The goal is to understand what you learn, connect it to what you already know, and use it to think, solve problems, and create something new.
That is the difference between knowing an answer and knowing why the answer works.
