Good marks do not always mean deep understanding, and understanding does not always produce good marks right away. Knowing which one your child is doing changes how you help them.
It is a conversation that comes up a lot among parents: their child does well on homework and then blanks on the test, or understands something one week and cannot recall it the next, or can repeat back a formula but freezes when the question is worded differently.
These are not signs of a bad memory or low ability. They are usually signs of a particular kind of studying: memorizing rather than understanding. And the two look almost identical from the outside until the moment they do not.
Why the Difference Matters More Than You Think
Memorization works. For a while. A student who memorizes a procedure can pass a test that asks them to repeat that procedure. The problem is that school, especially from Grade 7 onward, increasingly asks students to do something different: apply a concept to a new situation, explain their reasoning, connect one idea to another.
In Ontario, the most recent EQAO provincial assessments found that 51 per cent of Grade 6 students met the provincial standard in mathematics in 2024-2025. As the EQAO 2025 results show, the grade where students start to lose ground is often the grade where the curriculum shifts from recall to reasoning.
In subjects like math and science, this gap gets bigger every year. Grade 9 algebra builds on Grade 8 equations. Grade 11 functions build on Grade 9 algebra. A student who memorized their way through each level without truly understanding it hits a wall, usually around Grade 10 or 11, where there is simply too much to hold in memory and the conceptual foundation is not there to fall back on.
This is the most common pattern behind the student who was doing fine and then suddenly is not.
How Do You Know If Your Child Is Really Understanding the Material?
The clearest sign is whether they can apply what they know in a new situation, not just the one they practised. A child who understands something can use it in different contexts. A child who has memorized it can only apply it in the exact context they practised.
- They can recite a formula or a rule but cannot set up the problem when the wording changes slightly.
- They get stuck when a test question looks different from the homework, even though it is testing the same concept.
- They feel nervous or defensive when asked to explain their thinking out loud.
- Homework marks are consistently higher than test marks in the same subject.
- They study for a long time and still do not feel confident going into an exam.
None of these alone is definitive. But several of them together, particularly the gap between homework and test performance, is a reliable signal.
Signs of Real Understanding
Understanding looks and sounds different. A student who genuinely understands something tends to be curious about it rather than anxious. They ask questions about why, not just how. They notice when something connects to something else they already know.
- They can explain the concept in their own words, not just repeat the textbook definition.
- They can catch their own mistakes when reviewing their work, because they know what the answer should look like.
- They can solve a problem they have never seen before if the underlying concept is familiar.
- They say things like: oh, this is the same idea as what we did last month.
The last one is particularly useful. Noticing connections across topics is one of the clearest signs that knowledge is genuinely integrated rather than stored in isolated compartments.
Three Questions to Ask Your Child Tonight
You do not need to quiz them formally. Just have a conversation after dinner and try one of these.
- Ask them to explain something they are currently studying as if you have never heard of it. Not to recite the definition, but to explain it. Listen for whether they use their own language or fall back on memorized phrases.
- Pick a homework problem they got right and ask: how did you know to do it that way? A child who understands can walk you through their reasoning. A child who memorized a procedure often says: I just remembered that is how you do it.
- Ask: what would happen if this part of the problem was different? Pointing to one element and changing it. Understanding allows for flexible thinking. Memorization does not.
These conversations are useful not because they expose a problem, but because they make visible something that is otherwise easy to miss until an exam does it for you.
What to Do If It Is Mostly Memorization
The first thing is not to panic. Memorization is a legitimate part of learning. The goal is not to eliminate it but to build understanding alongside it.
The most effective shift is slowing down. Many students memorize because they are moving through material quickly and never stop to ask why. Taking one concept from the current unit and actually working through it together, asking questions, making connections, drawing it out, is worth more than re-reading notes three times.
How Connect Education Can Help
Connect Education works exclusively with Ontario Certified Teachers and ECEs in good standing. In a one-on-one session, a certified teacher can hear exactly where a student's explanation breaks down, ask the follow-up question that reveals the gap, and work on that specific point rather than the whole topic. That kind of targeted work is difficult to replicate in a classroom of thirty students where the lesson has to keep moving.
Start with a free 15-minute assessment to find out where your child's understanding breaks down and which certified teacher would be the right fit. Browse profiles and connect in person, online, or at a local library at connect-education.com.
Questions Parents Ask Most
How do you know if your child is actually learning or just memorizing?
The clearest sign is whether your child can transfer what they know to a new situation. A child who is genuinely learning can explain the concept in their own words, catch their own mistakes, and solve a problem they have never seen before if the underlying concept is familiar. A child who is memorizing can reproduce what they practised but tends to freeze when a question is worded differently or when the setup changes.
My child gets good marks but cannot explain the material. Should I worry?
It depends on the grade and the subject. In early elementary school, memorization is genuinely appropriate for a lot of content. From Grade 6 onward, particularly in math and science, good marks built entirely on memorization tend to become fragile. If your child consistently cannot explain what they know, it is worth addressing before the curriculum demands more of them than memorization can deliver.
Is memorization always bad?
No. Some things are worth memorizing: multiplication tables, key dates, vocabulary, formulas used constantly. The issue is when memorization is the only strategy a student has, used even for concepts that require reasoning. The goal is a mix: a solid base of memorized fundamentals that frees up mental space for the thinking work that builds on top of it.
How do I help my child understand math instead of memorizing the steps?
Ask why at every step. When your child shows you how they solved a problem, ask why they did each step rather than just checking the answer. This builds the habit of reasoning rather than recalling. If neither of you knows why a step works, that is useful information: a teacher or tutor can fill in the gap.
