Want to know what interleaving feels like? Try these quick math problems!
It's been awhile since we've talked about interleaving!
Years of cognitive science research have established that interleaving – simply rearranging the order of retrieval opportunities – can increase (and even double) student learning.
But what does interleaving actually look like? This week, try it for yourself!

Research by Doug Rohrer and colleagues demonstrates that the simple approach of interleaving and mixing up concepts to be learned can result in a large benefit for student learning – whether it's songs, math, science, vocabulary words, art history, and even baseball.
For example, when students complete four addition, four subtraction, and four division problems (e.g., AAAA BBBB CCCC), they can go through them without thinking about which strategy is appropriate. They don’t even have to read the words.
But when the math problems are interleaved (ACB BAC CAB), students have to choose and retrieve the appropriate strategy for each problem. Same exact problems – just simply rearranged! A critical key to interleaving: mix similar concepts to promote students' discrimination (like a fruit salad!).
Try these math problems and submit your answers on our Google Form:
A bug flies 48 miles east and then 20 miles south. How far is the bug from where it started?
A bug flies 48 miles east and then 14 miles north. How far is the bug from where it started?
A bug flies 48 miles east and then 6 miles west. How far is the bug from where it started?
These word problems appear to be similar and you may have applied the Pythagorean Theorem. But did you notice that the last problem requires a different strategy to solve it correctly (answers here)? Welcome to interleaving!
Sometimes concepts look alike, but they can require different strategies. And we want our students to recognize up from down, addition from subtraction. Note that this is a very simple example of interleaving. Of course, you'd want to mix up similar concepts (Pythagorean Theorem with other geometry concepts) to encourage students to discriminate. Click here for more examples of math problems by Doug Rohrer and colleagues.
If problems are mixed up and interleaved, students need to choose a strategy, not just use a strategy without thinking. It's not about tricking students; interleaving is a low-stakes desirable difficulty to improve understanding.
Take the content you already have, interleave it, and boost learning!

Want to improve students' study strategies? Do this first.
How often do students come to you and exclaim, "But I studied for hours!" Of course, we don't want to see our students study for hours on end, only to forget everything or fail a test. They don't want to get stuck in this cycle, either.
How can we help students improve their study habits? Before you give them strategies, there's one thing you have to do first: have a conversation.
Read on for three vital questions to ask students before diving into study strategies. You – and your students – will be surprised by the conversation.

We know that students don't study effectively. Plenty of research confirms that students cram, re-read, and highlight. Research also demonstrates that students can study less and learn more with retrieval practice, spacing, interleaving, and metacognition.
How can we help? Calendars and study plans are good, but telling or showing students how to use effective strategies is like driving a car that accelerates from 0 to 70 mph – in 60 seconds flat.
Slow down! Ask students these three simple questions:
How do you study?
Why do you study this way?
Does it work?
Your students will be mystified! Many students have never reflected on their study habits before and even fewer have been taught how to study effectively.
Share some of your own study experiences, too! Chances are you crammed at some point in your life. You should also tell your students they aren't alone – students from K-12 to college and medical school use the same ineffective strategies and get the same frustrating results.
What next? Check out our strategy called Retrieve-Taking to model effective study strategies in class before students try them on their own. Check out the Learning Scientists and this superb guide by cognitive scientists, too.
What's the most powerful strategy to improve students' study habits? It's the opportunity to have a conversation about how they study – first.

Retrieval Tic Tac Toe: A no stakes, no anxiety game for retrieval practice
Classroom games – like Jeopardy, trivia, or apps – encourage retrieval. But they can also raise student anxiety when they're competitive or time limited.
This week, we present a no anxiety strategy: Retrieval Tic Tac Toe. Created by college students, adaptable for any classroom or content area. Have fun!

The research is clear: Retrieval practice boosts learning. To get students on board, it's critical to emphasize that retrieval practice is a learning opportunity, not an assessment opportunity.
Classroom games, like Jeopardy and various apps (e.g., Kahoot, Quizlet, etc.) are engaging and low stakes – perfect for retrieval practice. But they can increase anxiety, too. When you were a student, did you ever feel pressured to come up with a correct answer to a question, as soon as possible, without disappointing your teammates? Talk about anxiety!
Retrieval Tic Tac Toe is a no stakes, no tech, no anxiety activity created by Alana, Emily, and J., college students in a psychology class with cognitive scientist Janell Blunt from Anderson University.
Write a tic tac toe grid on the board or project a grid on a screen
Split your class into two teams
Each team writes 5 questions for retrieval practice
One team stands at the front of the class and asks a question. The other team collaborates to come up with the correct answer.
If the seated team gets the question correct, they can put an X on the grid wherever they like.
The teams switch. Now, the team that originally presented collaborates, answers a question, and adds an O if they are correct.
Continue alternating teams for Retrieval Tic Tac Toe, anxiety free!
Quick tips:
Students can create questions about previously learned content to incorporate spacing in Retrieval Tic Tac Toe
Questions can be short answer or multiple-choice
You can create a few smaller teams (e.g., 3-4 students each) and have multiple games going at once
Play Retrieval Tic Tac Toe at the beginning, middle, or end of class
No prep or grading required!

Download our NEW Spacing Guide with practical strategies and research!
It's a brand new year. That means a brand new Spacing Guide to improve students' long-term learning! We're pretty excited.
Written by cognitive scientists, take a moment and download our free Spacing Guide, full of practical spacing strategies – and the research to back it up.
Could you spread the word about our new Spacing Guide? Let's get cognitive science into the hands of teachers – share it on Twitter and Facebook. Enjoy!

Spacing is a powerful strategy that boosts learning by spreading lessons and retrieval opportunities out over time so learning is not crammed all at once. By returning to content every so often, students’ knowledge has had time to rest and be refreshed.
When we teach and students study, we often focus on short-term learning. But with spacing, students' long-term learning dramatically increases. Spacing also comes with more than 100 years of research to back it up. We love it because it's not only effective, it's practical and easy to implement.
In our new Spacing Guide, learn about what spacing is, why it works, and how to implement it in the classroom. In just 12 pages (and free!), it's a resource we hope you'll read, share, and put into action for you and your students.
Did you know we have 4 guides (plus translations), with more on the way? Download them from our library, Teachers Pay Teachers, and Google Drive. Do you have an idea or topic you'd love to see us cover? Let us know! We're passionate about getting rigorous research into the hands of educators and we need your help to make it happen.

Yes, retrieval practice improves more than just memorization
This week, we want to address the single most frequent question we're asked: "Do these strategies improve more than just memorization?" Read on for our answer, based on years of cognitive science research and classroom practice. (Sneak peek: Download our free Transfer Guide for more info!)
Are you using retrieval practice, spacing, and feedback in your teaching? How's it going? Any questions we can help out with? Comment below and let us know!

We've said it before and we'll say it again: Yes, strategies like retrieval practice, spacing, interleaving, and feedback improve more than just memorization!
Whether you're new to retrievalpractice.org or just joining us, you may be wondering, “Retrieval practice sounds great, but it still sounds pretty basic.” Over the years, we’ve had the same concerns, too. Fortunately, in the lab and in the classroom, research demonstrates that these strategies improve students’ transfer of knowledge, ranging from a deep understanding of mitosis to effectively resuscitating someone using CPR. Simply bringing information to mind helps solidify knowledge and transfer it to new content and situations.
Transfer happens when students take something familiar and apply it to something unfamiliar. In the same way, what students learn inside the classroom should be applied outside the classroom – the hallmark of deep understanding and flexible knowledge.
As educators, we know that boosting learning beyond the memorization of facts is critical. And that’s why we advocate for the use of these strategies – because decades of research demonstrate that they improve more than just memorization – much more.
Download our free Transfer Guide, written by cognitive scientists, for key research and teaching strategies to boost students' transfer of knowledge. Getting students to transfer what they know isn't always easy. Check out our Transfer Guide and unleash our research-based tips in your classroom.

Flash Forward follow up: Two more strategies!
Did you read about our end-of-semester activity from last week, Flash Forward? This week, we have two strategies to take Flash Forward to the next level – by readers like you!
We love learning from your tips, ideas, and activities. To share, simply reply to this email, comment below, and join us on Facebook and Twitter.
What is something you've learned this year that you want to remember 10 years from now? Take this opportunity to Flash Forward for yourself!

Last week, we talked about an activity we love, called Flash Forward. Simply ask your students this question:
"Now that you've taken this class, what is one thing you want to remember 10 years from now (and why)?"
Flash Forward sparks retrieval, spacing, and metacognition – in 5 minutes or less. But what should you do next? Here are two fantastic recommendations from our readers:
Janell Blunt, a cognitive scientist and professor at Anderson University in Indiana, used Flash Forward with her college students last week:
Students think about or write down their Flash Forward
Students line up facing another student
Students share their Flash Forwards with their partner across from them
Students switch to a new partner (you can have one of the lines move down a spot and pair the two students on the end)
Students engage in class discussion of themes and reactions
After an activity like Janell's, another reader suggested taking Flash Forward to the next level by asking students:
"How will you remember that one thing? What will you do to make sure you don't forget?"
Don't be surprised if your students say they'll use retrieval practice!
Have you tried Flash Forward in your classroom? What did your students say? Do you have a tip to share? Let us know and comment below!
