Like all teachers, I’ve spent many hours correcting homework. Yet there’s a debate over whether we should be setting it at all.
I teach both primary and secondary, and regularly find myself drawn into the argument on the reasoning behind it – parents, and sometimes colleagues, question its validity. Parent-teacher interviews can become consumed by how much trouble students have completing assignments. All of which has led me to question the neuroscience behind setting homework. Is it worth it?

Increasingly, there’s a divide between those who support the need for homework and those who suggest the time would be better spent with family and developing relationships. The anxiety related to homework is frequently reviewed.
A survey of high-performing high schools by the Stanford Graduate School of Education, for example, found that 56% of students considered homework a primary source of stress. These same students reported that the demands of homework caused sleep deprivation and other health problems, as well as less time for friends, family and extracurricular pursuits.
When students learn in the classroom, they are using their short-term or working memory. This information is continually updated during the class. On leaving the classroom, the information in the working memory is replaced by the topic in the next class.
Adults experience a similar reaction when they walk into a new room and forget why they are there. The new set of sensory information – lighting, odours, temperature – enters their working memory and any pre-existing information is displaced. It’s only when the person returns to the same environment that they remember the key information.
But education is about more than memorising facts. Students need to access the information in ways that are relevant to their world, and to transfer knowledge to new situations.
Many of us will have struggled to remember someone’s name when we meet them in an unexpected environment (a workmate at the gym, maybe), and we are more likely to remember them again once we’ve seen them multiple times in different places. Similarly, students must practise their skills in different environments.
Revising the key skills learned in the classroom during homework increases the likelihood of a student remembering and being able to use those skills in a variety of situations in the future, contributing to their overall education.
The link between homework and educational achievement is supported by research: a meta-analysis of studies between 1987 and 2003 found that: “With only rare exceptions, the relationship between the amount of homework students do and their achievement outcomes was found to be positive and statistically significant.”
The right type of work
The homework debate is often split along the lines of primary school compared with secondary school. Education researcher Professor John Hattie, who has ranked various influences on student learning and achievement, found that homework in primary schools has a negligible effect (most homework set has little to no impact on a student’s overall learning). However, it makes a bigger difference in secondary schools.
His explanation is that students in secondary schools are often given tasks that reinforce key skills learned in the classroom that day, whereas primary students may be asked to complete separate assignments. “The worst thing you can do with homework is give kids projects; the best thing you can do is reinforce something you’ve already learned,” he told the BBC in 2014.
The science of homework: tips to engage students' brains
So homework can be effective when it’s the right type of homework. In my own practice, the primary students I teach will often be asked to find real-life examples of the concept taught instead of traditional homework tasks, while homework for secondary students consolidates the key concepts covered in the classroom. For secondary in particular, I find a general set of rules useful:
- Set work that’s relevant. This includes elaborating on information addressed in the class or opportunities for students to explore the key concept in areas of their own interest.
- Make sure students can complete the homework. Pitch it to a student’s age and skills – anxiety will only limit their cognitive abilities in that topic. A high chance of success will increase the reward stimulation in the brain.
- Get parents involved, without the homework being a point of conflict with students. Make it a sharing of information, rather than a battle.
- Check the homework with the students afterwards. This offers a chance to review the key concepts and allow the working memory to become part of the long-term memory.
While there is no data on the effectiveness of homework in different subjects, these general rules could be applied equally to languages, mathematics or humanities. And by setting the right type of homework, you’ll help to reinforce key concepts in a new environment, allowing the information you teach to be used in a variety of contexts in the future.

Kids Should Not Have Homework: 5 Arguments To Support Your Point
Homework has been a part of students’ lives for so long that the idea of not doing it can seem incredible, surreal, or even impossible. But if you stop to think about it, the truth is that homework is not necessary. Do you have trouble believing that? Well, here are a few great arguments that will definitely convince you.
Without further ado, here are the top five best arguments that will definitely convince any naysayers that homework is not something that should be done by kids.
- Kids already have seven hours of school. You start school at eight and go home at three. That’s a full day of school. Most adults work similar lengths of time at work and come home exhausted. Yet they can’t understand when their kids have trouble focusing at the end of a full day of learning. And that brings us to our next point.
- It’s counterintuitive to make children spend too many hours studying. If an adult has attention problems, that’s nothing compared to a kid. Children are still growing, their brains aren’t yet fully developed, and it’s crucial that they get a lot of exercise and free time. Something that they could do in thirty minutes if fully rested and energized will drag on for four hours if they’re restless and can’t focus because they left seven hours of school to directly jump into three hours of homework.
- Getting sun and exercise is crucial for your health. If you’re cooped up in school during the day, then have to do your homework when you get home, you’ll develop poor health. A much better solution would be to do all the learning you need to do in one place, in a short amount of time. When you stop school, that’s the time for you to play and go outside and get exercise.
- Seven hours of school should be enough to learn anything. Sure, let’s say that you have recess and lunch--there’s still a good five hours where you’re studying. If you can’t learn what you need in that time, there’s a problem. Rather than giving you lots of homework after school to compensate, schools should look at how they can rework teaching systems in class to make the most of the time you have in school.
- Having a social and family life is important. In short, you should have a balanced life. Many adults get angry if their work life spills over into their personal life. They like to go out after work and spend time with friends. But children should get the same respect. School is a time for learning, and it takes up much of the day. After school is the time for pursuing your own hobbies and personal pastimes.
