Many parents know the feeling: their child spends an hour rereading notes before a test, only to blank on the answers when it counts. Highlighting, repetition and rereading feel productive but these are among the least effective strategies for long-term memory retention. The problem is the method.That is where experts come in. Drawing on the brain science behind how children actually learn and retain information, experts reveal a deceptively simple technique that parents can use at home to dramatically improve how well their kids hold onto what they study.Below, we walk you through the method, the science behind it and how to put it into practice.
What is the 60-Second Teach-Back trick?
The technique is straightforward. After your child finishes studying a topic, whether it is a history lesson, a science concept or a vocabulary list, ask them to explain it back to you out loud.
Why the study methods most parents rely on often fall short and an expert approach that gets better results
They have 60 seconds, they cannot look at their notes and they need to talk about it as if they were teaching a younger student who has never heard of it before. Once the time is up, they can go back to their notes and fill in anything they missed.That is it. No flashcards, no apps, no special preparation. Just a conversation.According to a 2026 study published in Psychological Science (Association for Psychological Science), “Retrieval practice produced significantly greater long-term retention than repeated study, even when initial performance appeared lower.” This directly validates the core mechanism of the teach-back trick. Forcing children to recall information (instead of rereading) strengthens memory pathways and leads to better long-term retention.In an interview with the Times of India, David Smith, CEO of LA-based Silicon Valley High School, an innovative, AI-powered online institution dedicated to making quality education more accessible, shared, “What makes this technique so effective is that it flips the dynamic of studying. Instead of passively absorbing information, your child has to actively pull it out of their memory and put it into their own words. That act of retrieval is where real learning happens.”
Why the 60-Second Teach-Back trick works: The brain science
To understand why this trick is so effective, it helps to look at what is actually happening in the brain when a child uses it.
- It Activates Retrieval Practice: When the brain is forced to recall information rather than simply re-read it, the memory trace for that information becomes stronger. Each time your child retrieves a fact or concept from memory, the neural pathway connecting them to that information gets reinforced. Rereading notes, by contrast, creates the illusion of familiarity. The information looks recognisable on the page, which can make a child feel like they know it, even when they cannot actually recall it independently. Rereading gives kids a false sense of confidence,” Smith explained. “They see the words and think they know them but recognition is not the same as recall. The teach-back forces them to retrieve the information, which is a completely different mental process and a far more useful one.”
- It Exposes Knowledge Gaps Instantly: One of the most practical benefits of this technique is that it makes gaps in understanding visible right away. When a child cannot explain something in their own words, that is a clear signal that they have not fully processed it yet. This is something rereading doesn’t often reveal. A child can read the same paragraph five times and still not realise they do not truly understand it but the moment they try to explain it out loud without notes, the gaps become obvious, both to them and to the parent listening. “Parents often don’t realise how much their child hasn’t absorbed until they ask them to explain it,” said Smith. “It’s one of those moments where the child will start a sentence, pause and then say, ‘Wait, I actually don’t know this part.’ That moment of realisation is incredibly valuable. It tells them exactly where to focus next.” A 2026 study in the journal Memory & Cognition (Springer) established, “Retrieval attempts that reveal knowledge gaps enhance subsequent learning more than passive review, by guiding attention to missing information.” This supports that the technique exposes gaps instantly. Struggling to explain something isn’t failure, its what makes learning more efficient by showing exactly what needs to be relearned.
- It Builds Deeper Processing: When children translate information into their own language, they are memorising and making sense of it. This kind of deeper processing creates stronger, more flexible memories that are easier to access under pressure, like during a test. “The act of simplifying a concept, of finding the words to explain it to an imaginary younger student, requires a level of understanding that surface-level studying simply does not produce,” explained Smith.
- It Builds Confidence and Verbal Fluency: There is an added benefit that is perhaps more beneficial than test performance. Regularly explaining ideas out loud helps children become more comfortable articulating their thoughts, a skill that serves them well beyond the classroom. “The more a child practices explaining things clearly, the more confident they become in their own knowledge,” Smith noted. “Over time, this builds a kind of academic self-assurance that changes how they approach studying altogether. They stop dreading
tests and start trusting themselves.”
The teach-back trick works best when it becomes a regular habit rather than a last-minute fix. Parents can build it into their child’s daily routine very easily. A 2026 study in Journal of Educational Psychology (APA) found, “Students who engaged in teaching the material to others demonstrated deeper understanding and superior transfer performance compared to those who only reviewed content.” This study backs the “teach-back” element specifically. Explaining a concept out loud forces deeper processing and meaning-making, exactly what the 60-second method requires.
The brain science behind active recall and how parents can put it to work at home
David Smith suggested, “After dinner, ask your child to pick one thing they learned that day and explain it to you in 60 seconds. It does not have to be formal or structured. The goal is simply to get them retrieving information out loud regularly. Start small. One topic, one minute, no notes. If your child struggles, that is not a bad sign. It means the technique is doing exactly what it should be, showing them where the gaps are so they can go back and fill them in. Over time, you will notice them becoming quicker, clearer, and more confident in how they explain things.”The best part is that it requires nothing from parents except a willingness to listen. You do not need to know the subject yourself. Just ask them to teach you and let them do the work.
