How to Active Recall While Reading a Textbook

7 min read · FlashDeck

Here is how to active recall while reading: read one short section, close the book (or cover the page), and say or write the main points from memory before you check. Then turn whatever you missed into a question you will answer again tomorrow. That read-close-recall loop turns a textbook into practice instead of a highlighting marathon.

If your problem is finishing a chapter and remembering almost none of it, FlashDeck takes the notes you wrote while reading and turns them into daily review cards: Build my study plan.

Why highlighting while reading fails

Highlighting feels active because your hand is moving. But choosing a sentence to color is not the same as remembering it. A large 2013 review of study techniques rated both highlighting and rereading "low utility," while practice testing was rated "high utility" (Dunlosky et al., 2013).

The problem with highlighting:

• You decide what matters before you understand the section.
• Half the page ends up yellow, so nothing stands out.
• When you come back, you reread the yellow parts, which is just rereading with extra steps.

If you are wondering "is active recall really better than re-reading?", we lay out the numbers in Active Recall vs Rereading. Short version: yes, for anything you need to remember past tonight.

The read-close-recall loop

This is the core active recall reading technique. It works for any textbook, article or study guide.

1. Preview (30 seconds). Look at the section heading, bold words and any diagram.
2. Read one chunk. One subsection, or two to four paragraphs. Read to understand, not to memorize.
3. Close or cover. Flip the book face down or slide a sheet of paper over the page.
4. Recall (1 to 2 minutes). Say out loud or jot down: What was this about? What are the key terms? How do they connect?
5. Check. Open the page. Mark anything you left out or got wrong.
6. Capture. Write each miss as a question with its answer. Those become your review cards.

That is it. What is reading recall? It is simply step 4: pulling the ideas back without the page in front of you.

Active recall vs passive reading, in one example

• Passive: read three pages, highlight, feel good, forget by Friday.
• Active: read one page, close the book, write four bullet points, notice you forgot the second one, write a card for it.

The active version takes a few minutes longer per page and saves hours of rereading later.

Turn headings into questions

Textbook headings are free questions. Before you read a section, rewrite the heading as a question. Then read to answer it, close the book, and answer it from memory.

Active recall questions that work for any subject

Keep these templates handy while you read:

• What is ___? (definition)
• What are the parts / steps / stages of ___?
• Why does ___ happen? (cause)
• What happens if ___ changes? (effect)
• How is ___ different from ___?
• What is one real example of ___?

"Why" and "how is it different" questions are the strongest because they force you to connect ideas, not just repeat a word.

How often to stop on a dense page

How often should I do active recall while reading? It depends on how heavy the page is.

• Light reading (history narrative, novel chapters): stop after each subsection or every page or two.
• Medium (psychology, government, most intro courses): stop after every subsection, usually every 2 to 4 paragraphs.
• Dense (biology, chemistry, anatomy, anything packed with terms): stop after every paragraph or every diagram.

A good rule: if you cannot recall at least the main idea of what you just read, your chunk was too big. Make the next one smaller.

How to active recall while studying the same chapter later

Your first pass through the chapter is only half the job. The questions you wrote need to come back on a schedule: tomorrow, a few days later, a week later. That is spaced repetition, and it is what turns "I read it" into "I still know it on test day." If you do not want an app for that, How to Do Spaced Repetition Without Anki covers paper and spreadsheet options.

Writing cards from what you missed

After each section, aim for two or three cards. Not ten. Pick:

1. The main idea of the section, as a question.
2. Any key term you could not define from memory.
3. Anything you got wrong during the recall step.

Keep each card to one fact. "What are the three stages of mitosis and what happens in each?" is too much for one card. Split it into three.

Doing this by hand works, but it adds up. A single chapter can leave you with 30 or 40 cards, and then you need to remember which ones to review on which day.

This is where most people drop it. Writing every card and tracking when each one is due gets old fast. With FlashDeck, you paste the notes you took while reading (or upload the slides as a PDF), and it writes one card per fact, definition or formula using only what you pasted. You delete any card you don't want. Each day it shows only the cards that are due, in about 10 minutes. Build my study plan

Example with a biology page

Say you are reading a section titled "Photosynthesis: The Light Reactions."

Before reading, the heading becomes a question: What happens in the light reactions of photosynthesis?

You read two paragraphs, then cover the page and write:

• Happens in the thylakoid membrane
• Uses light energy
• Makes ATP and... something else?
• Water gets split

You check the page and find:

• Yes, thylakoid membranes of the chloroplast.
• Makes ATP and NADPH. (You forgot NADPH.)
• Water is split, and oxygen is released as a byproduct. (You forgot the oxygen part.)

Your cards from this section:

Three cards, all from real gaps. Tomorrow you answer them with the book closed.

How to improve reading recall over a whole semester

• Use the loop every time you read, even for "easy" chapters.
• Write cards the same day, while you still know what confused you.
• Review for about ten minutes daily instead of rereading on weekends.
• Mix older chapters in, so early material does not fade before the final.

Read once, remember it for the test

You now know how to active recall while reading; the next step is making sure those cards come back at the right time. Paste the notes from tonight's chapter, and FlashDeck writes the cards and shows you only what is due each day, starting with your first 10-minute review.

FAQ

How do you use active recall while reading a textbook?

Read one chunk, cover the page, and write or say the main points from memory. Then check, note what you missed, and turn those misses into questions. Review those questions again tomorrow and a few days later.

What is the active recall study method?

It is the habit of testing yourself instead of re-looking at your notes. You try to produce the answer first, then check. Researchers call it retrieval practice, and it is one of only two techniques a major 2013 review rated "high utility."

How often should I do active recall while reading?

Stop after every subsection for most textbooks, and after every paragraph or diagram for dense science reading. If you cannot recall the main idea, your chunk was too big.

Is active recall really better than re-reading?

For long-term memory, yes. In a 2006 study, rereading did slightly better on a test five minutes later, but self-testing won clearly after two days and one week (Roediger & Karpicke, 2006).

Can I use my reading notes as flashcards?

Yes, and it is a good idea. Rewrite each note as a question with a one-fact answer. FlashDeck can do that step for you: paste the notes and it writes one card per fact, definition or formula from only what you pasted.
