Build a study session that starts with a blank page, checks it in a second color, and spends its reading time on the misses.
Paper packet. Every task here also exists on screen, where it is checked automatically; answers written on paper are not assessed by Nydus. When you are back at a device, enter your answers there.
You will plan a study session that starts with an attempt from memory, checks it, restudies only the misses and tries them again, for chapters, problem sets and cards.
If you have taken the recall practice course, you know the move: produce the material with the source out of sight, and only then look. If you have not, that sentence is all you need. This lesson is about building a whole study session around that move, for the material a real student has — a chapter, lecture notes, a problem set, a stack of cards — so that the move stops being an exercise and becomes the way you study.
| Term | What it means |
|---|---|
| Retrieve-first session | A study session that begins by producing the material from memory, and spends its reading time on what that attempt missed. |
| Heading list | The topics you are about to recall, written without their content: the prompts, not the answers. |
| Blank page | Writing everything you can under each heading with the source shut. |
| Check in a second color | Opening the source and marking, in a different pen, what the blank page missed or got wrong. |
| Carry-over | What is still missed at the end of a session, written down to open the next one. |
Most study sessions start by reading. A retrieve-first session starts by writing. You shut the book, write what you can, and only then open it — and when you open it, you read to fill the holes the attempt showed you, not to go over the whole thing again.
The session has five phases, always in the same order. Headings only: list the topics you are about to recall. Blank page: under each heading, write everything you can with the source shut. Check in a second color: open the source, and mark what you missed or got wrong in a different pen. Restudy the misses: read only the marked points. Second attempt: shut the source again and write the marked points. Whatever is still missed goes on a short list that opens tomorrow's session.
The order is the whole method. The attempt has to come before the look, or the attempt becomes a reread. The check has to come after, or errors stand uncorrected: the IES practice guide (Pashler and colleagues, 2007) recommends quizzing with the answers checked, not quizzing alone.
Another way: picture
Think of a map with the roads you remember drawn in pencil. The second color marks the roads you left out. Tomorrow you do not redraw the whole map; you start with the roads in the second color.
Another way: steps
Dunlosky and colleagues (2013) reviewed ten common study techniques and rated two of them as high utility: practice testing and spacing. Practice testing means exactly the blank-page move — any low-stakes attempt to produce what you studied. In one of the best-known studies, Roediger and Karpicke (2006) had students study short prose passages. A week later, the group that had practiced recalling the passages remembered about 61 percent of the ideas; the group that had reread them remembered about 40 percent. The rereaders had felt more confident.
The finding is about groups and ways of spending time. It is not a forecast about you, on your material, this week. And reading is not useless: you have to read something once before there is anything to retrieve. The claim is only that, after the first reading, an attempt usually does more than another pass.
A retrieve-first session costs no extra time. A forty-five minute session might go: fifteen minutes on the blank page, eight checking, fifteen restudying the misses, and seven on the second attempt. The share that changes is reading: it shrinks to the misses, because the attempt has already shown you what you know.
Different material needs a different blank page. For facts and explanations, you write under headings. For a method — a math, chemistry or physics problem — the retrieval is working a problem with the solution covered. For vocabulary, it is saying the answer aloud before you flip the card. For a diagram, it is labeling a blank copy. The IES guide also suggests trying a few questions before a new chapter, as pre-questions: even wrong guesses tell you what to look for when you read.
The check is where a session goes wrong quietly. Mark a point as missed if you left it out, if you got it wrong, or if you wrote something so vague it would not earn credit — the treaty ended the war when the question will ask which treaty and which year. Do not give yourself the point because it looks familiar now that you see it. Familiar is what everything looks like with the book open.
The Bill of Rights is the first ten amendments to the US Constitution, ratified on December 15, 1791 (National Archives). A student preparing a quiz on it can run a whole retrieve-first session in half an hour.
Take a fictional student, Sam. Headings only: he writes the numbers 1 to 10 down the side of a page. Blank page: with the textbook shut, he writes what each one protects. He gets the First Amendment — religion, speech, the press, assembly and petition — the Second, the Fifth's right not to testify against yourself, and the Sixth's right to a speedy trial. Check: in green, he adds the Fourth (unreasonable searches and seizures), the Eighth (cruel and unusual punishment) and four more. Restudy: he reads only the green lines. Second attempt: he covers the page and writes the green lines again; two are still shaky. Those two open tomorrow's session. He read the chapter once, and every other minute was spent producing it.
"I should learn it first, then test myself." The attempt is part of the learning, not a check that comes after it. An attempt after one reading is the right time.
"A bad blank page means the session failed." A thin blank page is the session working: it shows exactly where the restudy time should go. The students in these studies who reread felt better and remembered less.
"I recognized everything when I checked, so I know it." Recognizing a point on the page and producing it without the page are different things. The check counts only what the blank page produced.
"Retrieval is for facts." For a method, working a problem with the solution covered is the retrieval. Karpicke, Butler and Roediger (2009) found that rereading was the study strategy the college students they surveyed reported most, and few named testing themselves as their main one.
Write the heading list from the chapter's section titles.
Nucleus / Mitochondria / Ribosomes / Cell membrane
The headings are prompts; none of the content is on the page yet.
Shut the book and write under each heading.
Nucleus: holds the DNA. Mitochondria: make energy (ATP). Ribosomes: ? Cell membrane: controls what goes in and out.
The question mark is useful: it marks a gap before the book is open.
Open the book and check in a second color.
Green: Ribosomes: build proteins. Green: nucleus is surrounded by a double membrane.
The green is the restudy list; everything in pencil is already produced and needs no rereading today.
Restudy the green, then shut the book and write it again.
Second attempt: ribosomes ✓, double membrane ✗ → carry over
One point is still missing, so it becomes tomorrow's first question.
Cover the worked solution and read only the question.
Q4: A car goes from 0 to 20 m/s in 5 s. Find its acceleration.
For a method, the question is the heading; the solution is the answer you must not see yet.
Work the problem on paper before uncovering anything.
a = (20 − 0) ÷ 5 = 4 m/s²
Working it is the retrieval: you have to recall the formula and the steps yourself.
Uncover the solution and compare line by line.
Solution: a = Δv ÷ t = 4 m/s² ✓. Q5 (stopping car): sign wrong ✗
Compare each line, not just the final answer, so a lucky answer is not counted as a known method.
Redo the missed problem with the solution covered again.
Q5 redone: a = (0 − 15) ÷ 3 = −5 m/s² ✓
The second attempt shows the method is back, not just understood while reading.
Cover the Spanish column and look only at the English.
Heading list: 20 English words
The English words are the prompts.
Say or write each Spanish word before uncovering it.
14 said, 6 blanks
Producing each word before the check is the blank page.
Check, restudy the six, and try the six again with the column covered.
A fictional student, Maya, has forty minutes for a biology chapter on the parts of a cell. Which plan is a retrieve-first session?
A fictional plan. Priya has 60 minutes for a retrieve-first session on a history chapter. She gives a third of it to the blank page, a twelfth to checking, a quarter to restudying the misses and the rest to the second attempt. Complete the worked split in minutes.
Give a third of the time to the blank page.
Blank page: 60 ÷ 3 = a minutes
The attempt is the part that does the work, so it gets the largest share of the time.
Give a twelfth of the time to the check.
Check: 5 minutes
Checking in a second color is quick; it only has to mark what was missed.
Give a quarter of the time to restudying the misses.
Restudy: 60 ÷ 4 = c minutes
The restudy goes only to the marked points, not the whole chapter.
Give what is left to the second attempt.
Second attempt: 60 − 40 = d minutes
The second attempt shows whether the misses are back, so it needs real time too.
Put the five phases of a retrieve-first session in order, one to a row: headings only, blank page, check in a second color, restudy the misses, second attempt.
| Phase | |
|---|---|
| Step 1 | |
| Step 2 | |
| Step 3 | |
| Step 4 | |
| Step 5 |
A fictional session on three topics from a set of lecture notes. Get all three topics checked against the notes, with every topic written from memory before its notes are opened.
This task has no paper form; do it on a device.
A fictional session. Jordan's notes on the causes of the American Revolution hold 22 key points. On the blank page he wrote 12 of them correctly. After restudying the rest, his second attempt with the notes shut got 2 more. How many points did the blank page miss, and how many go at the top of tomorrow's session?
Missed on the blank page: a
Carried to tomorrow: b
A fictional week of study for a first-year college student. For each kind of material, choose the retrieve-first move that starts the session.

| Lecture notes on the branches of government | |
| Chemistry problem set with worked solutions | |
| Spanish vocabulary cards | |
| Heart diagram to label |
Lesson test: one question per skill, one attempt each, no hints. Your answers are checked when you submit.
A fictional plan for a civics quiz on the Bill of Rights. Fill in what happens in each phase of a retrieve-first session.
| What you do | |
|---|---|
| headings only | |
| blank page | |
| check in a second color | |
| restudy the misses | |
| second attempt |
You can build a retrieve-first session for real material. Pick one thing you are studying, write its heading list now, and run the blank page before you open it. Next: turning a page of notes into questions. You can stop in the middle of any of this. Closing the page is the whole of stopping — your place and anything you had typed are already saved, and the lesson opens again where you left it.
12. Your turn: a Spanish vocabulary list of twenty words, step 3
Second attempt: 4 of 6 → carry over 2
The two still missed open tomorrow's session.
