Evidence of an Effective Study Strategy

Students often work hard, but not all study methods give the same return. A child can spend an hour rereading notes and still struggle to remember the method in a quiz. Another student might spend less time, but practise in a way that makes the brain retrieve, apply and correct information.

So what counts as an effective study strategy? The best answer is not a single trick. Research in cognitive and educational psychology points to a pattern: students learn more reliably when they practise remembering, spread practice over time, mix related question types, and review mistakes with feedback.

Effective study is active. It asks students to bring ideas back from memory, use them in new questions, and learn from the gaps.

What the research says

A major review by Dunlosky and colleagues compared ten common learning techniques and rated practice testing and distributed practice as high-utility methods for learning across many conditions.^[1] That matters for students because these methods are simple enough to use at home, in school revision, and during online maths practice.

By contrast, rereading and highlighting can feel productive, but they are often weaker when used on their own.^[1] They may help students become familiar with a page, but familiarity is not the same as being able to solve a question independently.

1. Retrieval practice: test yourself before checking

Retrieval practice means trying to bring an answer, formula, step or explanation back from memory before looking at the solution. It is not about high-pressure testing. It is about using recall as a learning tool.

Roediger and Karpicke showed that taking memory tests can improve later retention, even when the tests are used as learning activities rather than simply assessments.^[2] Karpicke and Roediger later found that repeated retrieval during learning played a key role in long-term retention.^[3]

For maths, this could mean covering the worked solution and asking, “Which operation comes first? What formula do I need? What does the question actually ask?” For NAPLAN or Selective Entry preparation, it could mean trying a question first, then reading the explanation afterwards.

2. Spaced practice: return to the topic later

Distributed practice, often called spaced practice, means spreading learning over time instead of doing one large session and moving on. Cepeda and colleagues reviewed research on distributed practice and found that spacing study opportunities is generally beneficial for later recall.^[4]

This is important because students often revise in one big burst before a test. That can create short-term familiarity, but it may not support durable memory. A better rhythm is to revisit a topic after a delay: today, later this week, and again before the test.

3. Interleaving: mix related question types

Blocked practice means doing many questions of the same type in a row. That can be useful when students are first learning a method. But once the basics are understood, students also need to practise choosing the method, not just repeating it.

Research on interleaving suggests that mixing related problem types can improve later performance because students must notice differences and decide which strategy fits.^[5] In mathematics, Rohrer and Taylor also reported benefits from shuffling practice problems rather than keeping practice entirely blocked by type.^[6]

For example, after learning perimeter, area and volume separately, a student should eventually see them mixed together. That forces the student to ask, “Is this asking for the outside edge, the space inside, or the amount a shape holds?”

4. Feedback: make mistakes useful

Retrieval practice works best when students do something with the result. A wrong answer should not simply be marked and forgotten. It should become information.

Classroom-focused work on retrieval practice has also highlighted that low-stakes quizzes and feedback can support learning in real educational settings, not only in laboratories.^[7] For students, the practical lesson is simple: answer first, check carefully, then correct the thinking.

A research-aligned 30-minute study routine

Here is a simple routine students can use for school maths, NAPLAN maths practice, or Selective Entry preparation:

• ✓ 5 minutes: quick retrieval warm-up from yesterday's topic.
• ✓ 10 minutes: focused topic practice while the method is still developing.
• ✓ 10 minutes: mixed practice so the student must choose the method.
• ✓ 5 minutes: review one mistake and schedule the topic for later in the week.

This routine uses retrieval, spacing, interleaving and feedback without making study feel complicated. It also keeps pressure low because the goal is not to be perfect. The goal is to practise in a way that strengthens memory and reasoning over time.

How parents can support evidence-based study

Parents do not need to become researchers or tutors. The most helpful role is to protect the routine and keep the emotional tone calm.

Final message

An effective study strategy is not the one that feels busiest. It is the one that helps students remember, choose, apply and correct. Research points strongly towards active recall, spaced review, mixed practice and thoughtful feedback.

For students, that means study should include questions, not only notes. For parents, it means the best support is a calm routine where mistakes are reviewed and topics return over time.
