Here are the four most powerful tools for long-term learning
/ Pooja K. AgarwalThis week, we feature a roundup of the four most powerful tools to boost students' long-term learning, backed by cognitive science research: retrieval practice, spacing, interleaving, and feedback-driven metacognition.
How do you use these four strategies? Share with us on Twitter and Facebook!
Four Power Tools for Powerful Learning
In Powerful Teaching, we highlight four Power Tools that make a big impact on students' long-term learning, even raising grades from a C to an A. Here are the four Power Tools, with our four favorite teaching strategies for each:
Retrieval Practice: Get information out of students' heads, not in
Download our Retrieval Practice Guide
Do you use study guides in your classroom, where key information is in outline form and students fill in the blanks during a lesson? Turn your study guides into Retrieval Guides without additional prep, grading, or class time! Download our Retrieval Guide Template for successful long-term learning.
There's a lot of discussion and research about students' study habits outside the classroom, including re-reading, taking notes, and highlighting. Students tend to use these strategies inside the classroom, too. In either setting, are students retaining what they're trying to learn? Potentially, but not always. Read more for our boost on note-taking, which we call retrieve-taking.
With the end of the semester within sight, we feature a small strategy that makes a big impact on student learning – based on decades of cognitive science research. In scientific lingo, we call it "free recall."
Spacing: Spacing learning over time; don't cram it all at once
Download our Spacing Guide
Did you read about our end-of-semester activity from last week, Flash Forward? This week, we have two strategies to add onto Flash Forward – by readers like you!
In this retrieval activity called Flash Forward, ask your students: “What do you want to remember 10 years from now?”. This is a critical question – one that you and your students need to ponder.
How can we help students build connections beyond the classroom? It can be hard. Really hard. Don't despair! This week, we feature Connection Notebooks, a quick evidence-based strategy by teaching expert and collaborator James M. Lang. They're the perfect opportunity to boost students' transfer of knowledge and extend learning from the classroom to the world beyond.
Are cumulative exams the same thing as spacing or interleaving? Actually, not quite. Cumulative exams can be beneficial for learning. But there are also some subtle ways we can take cumulative exams to the next level – by ensuring that we (and our students) are using spacing and interleaving throughout the semester, not just before the exam.
Interleaving: Mix up related information to foster discrimination
Download our Interleaving Guide
What is the optimal timing for retrieval practice? The answer—from the world’s expert on spaced retrieval practice, Dr. Shana Carpenter—may surprise you. Learn about spacing (aka spaced repetition), Dr. Carpenter’s research, and how to incorporate spacing in your teaching.
Get tips from cognitive scientist Dr. Veronica Yan, the world’s leading expert on interleaving. Boost student learning by mixing up concepts: problem sets, vocabulary words, different types of storytelling structures, etc. It’s a small adjustment that makes a big difference.
Are you learning to play an instrument? "Practice makes perfect," right? There's a catch: Just because you're practicing an instrument, a language, or even CPR resuscitation, it doesn't mean you're learning. What can you do? Use interleaving! Download our interleaving guide and read tips from an orchestra director. Boost learning and mix it up!
Resources are good. Templates are great! Check out Retrieval Grids, a flexible template you can download and create using low-stakes retrieval, spacing, interleaving, and feedback. Retrieval Grids aren't just for any classroom; adapt them for YOUR classroom!
Feedback & Metacognition: Help students reflect on what they know and what they don't know
Download our Transfer Guide (Metacognition Guide coming soon!)
We know research can be intimidating. This week, we feature our first Research Snapshot, a quick rundown of one powerful strategy and the research to back it up: Metacognition Sheets. We've removed the jargon, replaced it with key takeaways, and added a new download, too. Share our Research Snapshot and empower others to discover the science of learning.
This week, check out a new strategy: Metacognition Line Up. Get students moving, retrieving, and reflecting, regardless of grade level or content area. Metacognition Line Up moves quickly and can be completed in less than five minutes per round!
We know feedback is good for learning. But what's best? In our new guide on students' application and transfer of knowledge, we also feature research-based recommendations on feedback strategies. Why? Because transfer is most successful when retrieval practice is followed by feedback. Read more for our quick no-grading feedback strategies.
Whether you teach at an elementary school or a medical school, you've probably heard of the instructional strategy, think-pair-share. Don’t skip the “think” step! Read on for research-based tips on incorporating retrieval, spacing, and interleaving to make think-pair-share an even more powerful strategy in your classroom.
Supported by a wealth of research and featured in the book Make it Stick, these strategies don't require more prep or grading (because no one wants more of that, right?). We write about each of these strategies every week, but we thought it's long overdue to summarize all four Power Tools in one update.

"Give science away." This is what a cognitive scientist told me more than a decade ago and this is exactly why retrievalpractice.org exists. But science isn't always accessible. What can you do? Read our quick tip to access research. The science of learning has been under lock and key. Until now.
We love the science of learning. It's fascinating to think about and critical in the classroom. But what exactly does the "science of learning" really mean? Read on for the inside scoop!
Chances are you're familiar with Bloom's Taxonomy, the famous triangle diagram. But do we have to build students’ fact knowledge before engaging them in higher order learning? Or is it the other way around? According to new research, students can reach the top of Bloom's Taxonomy without starting at the bottom.
