At home, we’ve been having some conversations with my oldest about college life. She’s a high school junior, so that’s one of the next big steps around the corner. It’s led to many memories of my time in undergrad. As I was researching this classroom lie, I found myself thinking back on the spring of my sophomore year at Indiana University. It was the weekend before finals, and my first test was my US History final. It was a class that I took with several of the guys in my fraternity. We were sitting in the formal having a review session. In front of me were my textbook, my notes, a pen, and a highlighter. At the time, studying looked like re-reading my textbook and/or notes. In retrospect, that likely left me with a false sense of security because I felt I was familiar with the material. Students and teachers (falsely) assume this is a sign of learning.

The lie we’re going to address today is that going over notes and re-reading are effective ways to prepare for a test. But the reality is that some practices have a much stronger correlation with true learning. Re-reading may help a student prepare when they are cramming, but if you check their learning at a later date, it’s likely they will have lost it. So what does the research tell us?
Rodiger & Karpicke (2006) shared in Psychological Science that retrieval practice dramatically outperforms re-reading on delayed tests. The main finding of the study is that if a final test was 2-7 days away, students who had one study session followed by 1-3 no-stakes quizzes were more likely to show greater retention of the learning. The longer you need to remember information, the more powerful the “Testing Effect” is. On the other hand, re-reading is much less effective for long-term memory. In last week’s post, I shared Hermann Ebbinghaus’s work on the forgetting curve.

So if research shows that re-reading is not the best way to study, what should we do instead? There are several effective strategies that we can introduce to our students. One of the most tried-and-true methods is self-quizzing. This can be accomplished by having students create flashcards and using them to review. In teaching this strategy to our students, you might consider showing them how to place a card they got correct and felt confident with to the side, while adding ones they missed or don’t feel confident with to the back of the stack. This way, they can continue practicing the skills they don’t yet feel confident in. Students can go through their flashcards every day or two while learning the skill to build stronger neural pathways for that content. Another strategy that we can show our students is to have them partner up and ask each other the questions from the flashcard. This could be easily replicated with a family member at home.
Another way to build retrieval practice into classroom learning time could be with something like exit tickets at the end of a lesson, a warm-up at the beginning of the next day, or a “brain dump” before reopening notes or a textbook. A guiding question could be “What did we learn yesterday?” that asks students to jot down a main idea or key details from the lesson.
As an added bonus, when our students engage in low-stakes quizzes given by teachers for review, we help reduce students’ test anxiety by building their confidence in their ability to respond to questions. This feels counterintuitive, because it’s a quiz, but when it is low-stakes and becomes routine for students, research supports it as a high-impact learning tool.
To make the switch from reviewing to retrieving, you might start small. You could have students jot down 1 or 2 things they know or recall about the topic. With time and consistent use, students will become more confident in their knowledge. Another strategy is to plan your spiral review by asking a question from learning yesterday, last week, or last month. If you build a review like this into your planning process, you could add a portion to your lesson plans of a question from this lesson for:
- Tomorrow
- Next week
- Next month
Then, when it’s time to build your warm-up or review, you pull questions from your past lesson plans.
Here’s an honest caveat: your students will continue to gravitate towards re-reading, highlighting, or underlining because they feel more at ease. But that ease is also why they don’t work as well. When something is easy, you don’t help your brain build the strong neural pathways that support true learning.
One other thing to keep in mind is that retrieval practice works best when students have enough prior knowledge of a skill to attempt to retrieve. Students who are novices at a skill won’t be able to retrieve because they can’t access information that isn’t there. If you are at the beginning of an entirely new unit, you might consider using some retrieval practices from a past unit as review until your students have a base of knowledge.
I’m curious to know, what study strategies do you believe work best for you? What information from this post might have challenged your thinking the most? Share your thoughts in the comments below.
If you’d like more information on these topics, you can check out Roediger & Karpicke’s student here. Or you can check out this landmark review by Dunloski et al. of 10 strategies, which ranks retrieval practice as the highest outcome, and re-reading near the bottom. That study is available here. And if you want to dig deeper into retrieval practices, check out Make it Stick by Brown, Roediger, & McDaniel as an accessible book version of the research. That book is available here.
Next week, we’ll dig into the idea that we must build relationships before we engage in content. This one is challenging even some of my long-standing beliefs. We’ll dig into it here!
