Activating Prior Knowledge
Activating Prior Knowledge is a reading strategy that helps you understand a text better. It means you stop and think about what you already know before you read and while you read.
Your brain is full of facts, memories, and experiences. When you connect those things to a new text, the text makes more sense. It is like using what you already know as a bridge to help you learn something new.
For example, if you are about to read a story about a thunderstorm, you might think about a time you heard loud thunder, saw lightning, or stayed inside during heavy rain. Those thoughts can help you understand the story setting and the characters' feelings.
Why is activating prior knowledge important?
- It helps you understand new ideas.
- It helps you make predictions about what you will read.
- It helps you remember important details.
- It helps you ask better questions while reading.
- It helps you connect the text to your own life and to other things you have learned.
What counts as prior knowledge?
Prior knowledge is anything you already know that can help you understand a text. It can come from many places.
- Your life: things you have done, seen, heard, or felt
- Other books: stories, articles, poems, or textbooks you have read before
- School learning: facts you learned in science, social studies, math, or art
- The world around you: holidays, weather, sports, animals, places, and events
When should you activate prior knowledge?
- Before reading: Look at the title, pictures, headings, and captions. Ask yourself, “What do I already know about this topic?”
- During reading: As you read, stop and think, “Does this remind me of something I know?”
- After reading: Think about how your old knowledge and the new information fit together.
How do you activate prior knowledge?
You can use simple questions to wake up your thinking.
- What do I already know about this topic?
- Have I ever experienced something like this?
- Have I read about this before?
- What words, pictures, or ideas seem familiar?
- What do I think I might learn?
Clues in the text can help you activate prior knowledge.
Writers often give you clues before the reading even begins. The title, illustrations, chapter names, and bold words can all remind you of things you already know.
If a nonfiction article is called How Bees Help Flowers Grow, you may remember seeing bees in a garden. You may also remember learning that plants need pollen. That prior knowledge helps you understand the article more quickly.
Be careful: prior knowledge should help, not confuse you.
Sometimes readers think they know what a text will say, but their idea does not match the text. Good readers stay flexible. They use prior knowledge to start thinking, but they also pay close attention to the author’s actual words.
In other words, do not let your own ideas replace the text. Let your ideas support your reading.
A helpful way to think about it
Imagine your brain is a closet full of labeled boxes. Each box holds things you already know. When you begin reading, you open the boxes that match the topic. Then, as you learn new information, you place it in the right box. That makes learning easier and neater.
Worked Example 1: Everyday life connection
Text title: A Snowy Day at School
Step 1: Think before reading. Ask, “What do I already know about snowy days?”
- Snow is cold.
- Roads can be slippery.
- People wear coats, hats, and gloves.
- Schools sometimes start late or close.
Step 2: Use that knowledge. Now you can predict that the story may include cold weather, winter clothes, and changes to the school day.
Step 3: Read and check. If the story says the buses were late because of icy roads, your prior knowledge helped you understand why.
What we learned: Prior knowledge helped the reader understand the setting and predict events.
Worked Example 2: Nonfiction topic
Text title: The Life Cycle of a Frog
Step 1: Think before reading. Ask, “What do I already know about frogs?”
- Frogs live near water.
- Frogs lay eggs.
- Baby frogs are called tadpoles.
Step 2: Start reading. The article explains that tadpoles grow legs and lose their tails.
Step 3: Connect old and new ideas. You already knew frogs begin as eggs and tadpoles. Now you add new learning: tadpoles change as they grow.
What we learned: Prior knowledge gave the reader a starting point, and the text added more details.
Worked Example 3: Using prior knowledge during reading
Sentence from a story: “Maria’s hands shook as she walked onto the stage and looked at the crowd.”
Think during reading: What do I already know about being on a stage?
- People may feel nervous before performing.
- A large crowd can make someone feel scared or excited.
- Shaky hands can be a sign of worry.
Conclusion: Even if the story does not say “Maria was nervous,” your prior knowledge helps you infer that she may be feeling nervous.
What we learned: Prior knowledge can help you understand a character’s feelings.
Worked Example 4: When prior knowledge must be adjusted
Text title: Bats: Helpful Creatures of the Night
Step 1: Prior knowledge. A reader might think, “Bats are scary.”
Step 2: Read carefully. The article explains that many bats eat insects and help farmers by reducing pests.
Step 3: Adjust your thinking. The reader changes from “Bats are just scary” to “Bats may look unusual, but they are also helpful animals.”
What we learned: Prior knowledge is useful, but readers should be ready to learn something new and change their thinking.
Tips you can use every time you read
- Pause before reading and look at the title and pictures.
- Say or write one thing you already know about the topic.
- Make a prediction.
- Stop during reading to connect new ideas to old ideas.
- Change your thinking if the text teaches you something different.
Sentence starters for activating prior knowledge
- This reminds me of...
- I already know that...
- I have learned before that...
- I think this text might be about...
- This is similar to...
- Now I understand more because...
Try it on your own
Before you read a new story or article, ask yourself these three questions:
- What do I already know about this topic?
- What clues do the title and pictures give me?
- How might my background knowledge help me understand the text?
If you answer those questions, you are activating prior knowledge.
Quick review
Activating prior knowledge means using what you already know to help you understand what you read. You can do this before, during, and after reading. It helps with understanding, predicting, remembering, and making strong connections to the text.
Brief Summary
Good readers do not begin a text with an empty mind. They bring their own knowledge with them. When you activate prior knowledge, you give yourself a strong start and make reading easier and more meaningful.
