Spaced Practice and Retrieval Practice for Families
Spaced practice means spreading it out over days. Retrieval practice means bringing it back from memory, not reading it again. In the studies we hold, both helped people keep what they practiced. Our suggestion at home: keep it short and spread out. Have your child say it or write it from memory, then check.
TL;DR
- Spaced practice means spreading it out over days. Retrieval practice means bringing it back from memory. You do not read it again. You bring it back.
- In one study, some students reread a text, and some took recall tests (Roediger and Karpicke, 2006). Rereading looked better at first. Days later, the tested students remembered more. A later review found the same in many settings (Karpicke, 2017).
- One large review looked at practice with words and similar material (Cepeda and colleagues, 2006). Practice spread out was kept longer than the same practice all at once.
- Our suggestion is short, spread out, and from memory, then check. That routine is ours. Part of it has been tested.
- Roediger and Karpicke, Cepeda and colleagues, and Jones and colleagues measured memory for what was practiced. None measured reading skill or school grades. We hold no study of these two ways to practice in children with dyslexia or ADHD.
Two ways to practice
This page is about how to practice, not what to practice.
Spaced practice means spreading practice out. A little on several days, not all of it on one night.
Retrieval practice means pulling something back from memory. Your child says the word, or writes it, without looking. Then they check.
The opposite of retrieval is looking at it again. Rereading notes is looking again. So is copying a word over and over.
You can do both at once. Pull it from memory, and do that on more than one day.
Why rereading feels better than it is
In one study, students read passages of text (Roediger and Karpicke, 2006). Some read them again. Others took recall tests with no answers given. On a test five minutes later, rereading looked better. Two days and one week later, the tested students remembered more.
That is one study. The summary we hold does not give the students' ages.
Rereading feels easy, so it feels like it is working. The harder way is pulling it back. In that study, it held up better days later.
Researchers call this the testing effect. A later review found it again in many settings (Karpicke, 2017). We hold only a short summary of that review.
Here, "test" means a way to practice. It does not mean a grade.
Spreading it out
One review pooled 317 experiments on recalling words and other verbal material (Cepeda and colleagues, 2006). What was practiced in spread-out sessions was remembered longer than the same practice done all at once.
The review also looked at the gap between sessions. The best gap grew with how long the thing had to be kept.
The review gives no gap for your child. It looked at memory for words and similar material. It did not look at school grades.
Cramming the night before may get a child through Friday. In our view, it is a poor way to keep a word until June.
Spelling words from memory
In three small studies, first and second graders heard a word, wrote it from memory, then checked it. That beat copying the words over and over (Jones and colleagues, 2016). Those children were not picked for spelling trouble.
Each group was small. The studies measured spelling. They did not measure reading.
Copying a word looks like hard work. In those studies, writing it from memory did better.
Our page on spelling difficulties has more on spelling.
How to use this at home
This part is our suggestion. It is how we would set up practice at home.
Keep it short. In our view, a few minutes is enough. Stop while it is still going well.
Spread it out. Do a little on several days, not all of it the night before.
Pull it from memory, then check. Your child says it or writes it without looking. Then they look and check. Fix any slip, and move on.
Spelling words. Say the word. Your child writes it from memory, then checks it against the list. Our page on spelling difficulties has a routine for a word that will not stick.
Math facts. Ask the fact. Your child says the answer, then checks. Our page on forgetting math facts covers one small study of fact practice.
A story. After a chapter, ask your child to tell it back to you. Then look back at the page together.
That routine is ours. Two parts have been tested in the studies above: pulling it from memory, and spreading it out. We hold no study of this home routine as a whole.
In our view, practice the real school work itself. Spelling words, math facts, the book. Practice reaches the thing it is practice at.
What the research we hold does not show
This part covers the limits of the studies on this page.
Roediger and Karpicke, Cepeda and colleagues, and Jones and colleagues measured memory for what was practiced. None of them measured how well a child reads. None of them looked at school grades. We hold only a short summary of the 2017 review. We cannot say whether it looked at reading or grades.
Jones and colleagues studied first and second graders. The summaries we hold of Roediger and Karpicke, and of Cepeda and colleagues, do not give ages.
We hold no study of these two ways to practice in children with dyslexia or ADHD. That is a gap in what we hold, not a finding that it does not work.
No study of any Learning Success program exists.
If your child has lost a skill
Some children could do something and now cannot. That is different from a child who has not built the skill yet. Our position is that a lost skill goes to a doctor first, not a tutor.
When to ask for help
Each of these is a reason to ask for help on its own.
- Little change, even with steady practice and good teaching.
- Schoolwork well below what school expects.
- A teacher who raises a concern about learning.
- Extreme upset about schoolwork.
- Complete avoidance of school or learning.
- Hopelessness about learning.
- Sadness or worry that lasts.
- Significant delays in speech, language or motor development.
- A skill that was there and has gone. Our position is that a lost skill goes to a doctor first, not a tutor.
If no skill has gone, start with the teacher. Say what you are seeing at home, and what you have tried. Beyond the teacher, the right person depends on what it turns out to be about. If the work is too hard, someone who works on that school skill. If worry or mood is the thing, someone who works with children's mental health. In our view, delays in speech, language or movement are worth raising with your child's doctor. In our view, if you are worried enough to ask, a professional evaluation is worth asking about.
Any talk of hurting themselves is a same-day call to your doctor or a crisis line.
In the classroom
A short recall at the start of a lesson is practice, not a grade.
Come back to last week's words this week. Spread it out.
Two sentences for an email home: "We are practicing these words from memory, a little each day. Could you ask for three of them tonight, then check together?"
What to use next
Key Takeaways
Spaced practice is spreading it out. Retrieval practice is pulling it back from memory.
In one study, rereading looked better at first. Days later, the students who were tested remembered more.
In one large review, spread-out practice was remembered longer than the same practice all at once.
At home, keep it short, spread it out, and pull it from memory, then check. That routine is ours.
The 2006 study, the 2006 review and the spelling studies measured memory, not reading skill or grades. We hold no study of these two ways to practice in children with dyslexia or ADHD.
Tonight, pick three words or facts your child is learning. Ask for each one from memory. Then check together. Ask again another day. This is practice, not a grade.
”What to do tonightCommon questions from parents
Is this just testing my child?
Not for a grade. Here, a test is a way to practice. Your child pulls the answer from memory, then checks it. Nothing is scored. A slip is just the next thing to fix.
Are flashcards good or bad?
It depends on how they are used. A card your child answers before turning it over is retrieval practice. A card your child just reads is looking again. This page makes no claim for any app or card set.
How far apart should practice be?
One review looked at the gap between sessions (Cepeda and colleagues, 2006). The best gap grew with how long the thing had to be kept. The review gives no number for your child. In our view, a day or two apart is a fair place to start.
My child gets upset when they can't remember. What do I do?
Keep it short, and stop while it is going well. Give the answer, and come back to it another day. In our view, a slip is part of practice. If upset about schoolwork is extreme, that is a reason to ask for help.
Does this work for a child with dyslexia or ADHD?
We hold no study of these two ways to practice in children with dyslexia or ADHD. Roediger and Karpicke, Cepeda, and Jones did not pick children for those. That is a gap in what we hold, not a finding that it does not work. If reading is hard, reading improves with reading instruction, so keep it going.
