Memorisation: gentle methods that last

‘He knew his lesson last night, and this morning he remembers nothing.’ Every parent has said it. It says nothing about the child’s ability — it says everything about the method. Memory follows rules that are known and simple; it is enough to work with them rather than against them.

Spaced repetition: review little, review often

Information reviewed once fades within days. The same information reviewed at increasing intervals — the next day, then three days later, then the following week — settles for good. It is the most solid principle in all memory research, and the easiest to apply:

• In the evening: five minutes to review the day’s lesson.
• The next day: two minutes to reactivate it.
• At the weekend: a quick pass over the week’s lessons.

Twelve minutes in total, spread out — against an hour of cramming the night before the test, forgotten the following week.

Active recall: search, do not reread

Rereading a lesson gives a misleading sense of mastery: the child recognises the text, they do not know it. Memory strengthens when it is asked to produce the answer, not to recognise it. In practice: close the exercise book and ask three questions. What does the lesson say? Give me an example. What did you not understand? Searching for the answer — even getting it wrong — anchors far more deeply than ten rereadings.

What a child retrieves alone belongs to them. What they reread merely passes through.

Putting it in their own words: to explain is to understand

Ask your child to explain the lesson to you as though you did not know it. If they manage in their own words, the idea has been grasped. If they recite it word for word but cannot answer a simple question, they have memorised the form without the substance — and it will not hold. This habit of reformulating works for everything: a grammar rule, a theorem, a history lesson, a text learned by heart.

What damages memory

Three enemies, always the same ones: lack of sleep — it is during the night that the brain consolidates what was learned during the day — sessions that run too long, and working in noise or in front of a lit screen. A child who sleeps well and revises for fifteen minutes in quiet remembers more than an exhausted child who revises for an hour.

This is the approach our teachers apply in class and in student follow-up: short, regular, active appointments. It asks less effort than constant cramming. It simply gives better results.
