The most common way students waste study time
Ask a student how they prepared for a maths test and the honest answer is often: they read over their notes, looked at some worked examples, and highlighted a few things. It feels like studying. It takes real time. And it usually does very little for the mark.
The problem is that re-reading trains recognition, not recall. When your child looks at a worked solution the steps make sense, so their brain registers a comforting signal: I know this. But recognising a method when it is sitting in front of you is a completely different skill from producing it from a blank page under time pressure, which is exactly what a test demands.
That gap, between how well we think we know something and how well we actually know it, is well documented. Re-reading reliably inflates confidence without a matching improvement in performance.
What works instead
Answering questions without the notes open. That is it. Retrieval practice, sometimes called the testing effect, is among the most consistently supported study techniques there is, and it works for a simple reason: the effort of pulling something out of memory is what strengthens the path back to it. Reading it again does not require that effort, so it does not build the same strength.
There is a useful rule of thumb here. If it feels easy, it probably is not working. Productive study should feel effortful.
What this looks like in practice
Instead of your child reading over the fractions chapter:
- Give them a set of fractions questions with the notes closed.
- Let them struggle for a genuine minute before they look anything up. The struggle is the useful part.
- Mark it together and sort the errors: silly mistake, method gap, or ran out of time.
- Re-teach only the method gaps, then test those again a few days later.
The order matters. Test first, teach to the gaps, then test again. Many families do it the other way around and wonder why the mark does not move.
The one caveat
Retrieval practice works best once your child has actually been taught the material. Testing a student on something they have never seen is just demoralising. If they genuinely do not know the topic yet, teach it first, then switch to testing as the main study mode.
