Teaching hack: How to beat the forgetting curve
Help your students remember what really matters
Why do students forget what they learn?
Teachers see it all the time: students seem to master a topic, only to forget most of it days later. But this isn’t laziness, it’s how memory works.
Studies show that most learners forget 70–90% of new information within days. The brain constantly filters what it thinks is relevant. If something isn’t used, it’s often lost. This phenomenon is known as the forgetting curve, first studied by German psychologist Hermann Ebbinghaus.
The good news? Teachers can interrupt this curve and help students move from short-term recall to long-term learning.
What exactly is the forgetting curve?
The forgetting curve is a visual model of how quickly we forget new information over time—unless we make an effort to retain it.
Ebbinghaus discovered that right after learning something new, memory begins to fade almost immediately. However, with the right strategies—especially spaced repetition and retrieval practice—this curve can be flattened, and retention significantly improved.
6 science-backed strategies to boost memory in your English class
1. Use active recall
Don’t just re-read content. Ask your students to recall it from memory—without looking at their notes. Example: After a vocabulary lesson, ask them to write or say the words from memory.
2. Apply spaced repetition
Instead of reviewing everything at once, space it out. Revisit the same content one day later, then three days later, and so on. This boosts long-term memory and reduces mental overload.
3. Encourage meaningful connections
Help students link new content to real life. When they can relate, they retain.
Example: Teaching “delicious”? Ask them to describe their favorite meal.
4. Practice interleaving
Alternate topics during review sessions, mix grammar, vocabulary, and speaking practice. This helps students learn how to switch gears and apply knowledge flexibly.
5. Turn review into a game
Gamified retrieval is incredibly effective. Use flashcards, team quizzes, or memory races. A short 5-minute review game can boost participation and retention.
6. Add reflection moments
Let students explain what they’ve learned in their own words—through journaling, drawing, or peer teaching. These moments of reflection strengthen memory and confidence.
Try this in your next class
You don’t need a full curriculum overhaul. Just try one or two of these simple ideas:
- Add 3 review questions at the beginning of class
- Turn vocabulary into a team challenge
- Revisit grammar points every few days
- Ask students to teach a concept to a peer
Remember: repetition with purpose beats repetition by habit. By using these strategies, you’re not just teaching English—you’re helping students build memory habits that will last a lifetime.
