Why your child can read their revision notes for hours and still not learn much
Most of us will recognise this one from our own school days. You sit down with your notes, read through them once, then read them again. Perhaps you underline a few things along the way. After a while, the page starts to look reassuringly familiar. You recognise the words, remember seeing the diagram and begin to think, "Yes, I know this." Your child might be doing exactly the same thing today. They have their textbook open, their notes beside them and perhaps their phone safely out of reach. They have been sitting there for an hour, so when you walk past and ask, "Are you getting on with your revision?", it feels reassuring when they say yes.
But there is a problem with reading something over and over again. Recognising something isn't the same as being able to remember it.
Why re-reading feels like learning
It's easy to understand why re-reading has become such a popular way to revise. It feels productive because the information is right there in front of you, so there is no sense of getting stuck. Each time you read the same page, the words become a little more familiar and the subject starts to feel easier. That feeling can be quite convincing, particularly when your child has spent a long time sitting at their desk and feels as though they have been working hard.
Imagine your child is revising the causes of the First World War. They have read the same page in their textbook three or four times. If you put the page in front of them and ask, "Do you understand this?", they might quite reasonably say yes. Everything looks familiar and they can follow the explanation because the information is there to remind them. Now take the book away and ask them to explain the main causes without looking. Suddenly, things can feel very different. They might remember a couple of words or an acronym they've been using, but struggle to explain what those words actually mean.
The information felt familiar when it was sitting in front of them, but that familiarity can give them a slightly misleading sense that they have learned it. This is sometimes called the illusion of learning. It doesn't mean your child is doing anything wrong. It simply means that our brains can be quite easily fooled into thinking that familiarity means knowledge.
Think about watching the trailer for a film several times. By the fifth viewing, you probably know the music, the images and some of the dialogue almost without thinking. But that doesn't mean you could tell someone the whole story of the film without seeing the trailer. You have become very familiar with the information, but familiarity isn't the same as being able to produce it yourself. Revision works in much the same way.
Effective learning can feel harder
There is a slightly strange thing about effective revision that is worth understanding as a parent: it can actually feel harder than ineffective revision. Reading the same notes again is relatively easy. The answers are there in front of you, so your child can work for quite a long time without feeling particularly challenged. Close the book and try to remember what was on the page, however, and suddenly the brain has to work much harder. Your child might forget something, get an answer wrong or realise that they can't explain something as well as they thought they could.
That can feel frustrating, but it is actually useful. When your child has to retrieve information from memory, they are doing something fundamentally different from simply looking at it. They are finding out what they can remember without the answer being provided for them. That little bit of struggle is often a much better indication of whether learning has really taken place.
This is why techniques such as answering practice questions, using flashcards properly, explaining something without looking at notes or writing down everything you can remember before checking the answer can be so effective. They don't just give your child more information to look at. They make your child think with the information they already have.
So what can parents actually do?
The good news is that you don't need to become your child's teacher or start writing revision timetables for them. You can help simply by changing the questions you ask. Instead of asking, "Have you done your revision?", you could occasionally ask, "What can you remember from what you've just revised?" You don't need to test them or mark their answers. You could even make it part of an ordinary conversation. If they've been revising the causes of the First World War, ask them to explain the main causes while you're making dinner or walking the dog. If they've been revising a science topic, ask them to explain it to you as though you know nothing about it.
If they can explain it clearly without looking at their notes, that's useful information. If they get stuck, that's useful information too. It tells them exactly where they need to go back and look again. And that's an important shift in thinking: good revision isn't about avoiding the things your child can't remember. It's about finding them.
Don't stop them reading - Just don't let reading be the whole strategy
There is nothing wrong with reading notes. Your child obviously needs to encounter new information before they can learn it. Reading can help them understand a topic, remind themselves of something they have forgotten and fill gaps in their knowledge. The problem comes when reading becomes the whole revision strategy.
If your child spends an hour reading their notes, don't assume that they've learned more simply because they've spent an hour studying. Encourage them to put the notes away and see what they can actually remember. Make them answer the question before looking at the answer. Ask them to explain an idea in their own words. In other words, don't just ask your child to look at what they know. Ask them to show what they know.
Because ultimately, revision isn't about how familiar the page looks. It's about what your child can still remember when the page isn't there.
