Should homework be banned?

We’ve all done it: pretended to leave an essay at home, or stayed up until 2am to finish a piece of coursework we’ve been ignoring for weeks. Homework, for some people, is seen as a chore that’s ‘wrecking kids’ or ‘killing parents’, while others think it is an essential part of a well-rounded education. The problem is far from new: public debates about homework have been raging since at least the early-1900s, and recently spilled over into a Twitter feud between Gary Lineker and Piers Morgan.

Ironically, the conversation surrounding homework often ignores the scientific ‘homework’ that researchers have carried out. Many detailed studies have been conducted, and can guide parents, teachers and administrators to make sensible decisions about how much work should be completed by students outside of the classroom.

So why does homework stir up such strong emotions? One reason is that, by its very nature, it is an intrusion of schoolwork into family life. I carried out a study in 2005, and found that the amount of time that children and adolescents spend in school, from nursery right up to the end of compulsory education, has greatly increased over the last century. This means that more of a child’s time is taken up with education, so family time is reduced. This increases pressure on the boundary between the family and the school.

Plus, the amount of homework that students receive appears to be increasing, especially in the early years when parents are keen for their children to play with friends and spend time with the family.

Finally, success in school has become increasingly important to success in life. Parents can use homework to promote, or exercise control over, their child’s academic trajectory, and hopefully ensure their future educational success. But this often leaves parents conflicted – they want their children to be successful in school, but they don’t want them to be stressed or upset because of an unmanageable workload.

However, the issue isn’t simply down to the opinions of parents, children and their teachers – governments also like to get involved. In the autumn of 2012, French president François Hollande hit world headlines after making a comment about banning homework, ostensibly because it promoted inequality. The Chinese government has also toyed with a ban, because of concerns about excessive academic pressure being put on children.

The problem is, some politicians and national administrators regard regulatory policy in education as a solution for a wide array of social, economic and political issues, perhaps without considering the consequences for students and parents.

Does homework work?

Homework seems to generally have a positive effect for high school students, according to an extensive range of empirical literature. For example, Duke University’s Prof Harris Cooper carried out a meta-analysis using data from US schools, covering a period from 1987 to 2003. He found that homework offered a general beneficial impact on test scores and improvements in attitude, with a greater effect seen in older students. But dig deeper into the issue and a complex set of factors quickly emerges, related to how much homework students do, and exactly how they feel about it.

In 2009, Prof Ulrich Trautwein and his team at the University of Tübingen found that in order to establish whether homework is having any effect, researchers must take into account the differences both between and within classes. For example, a teacher may assign a good deal of homework to a lower-level class, producing an association between more homework and lower levels of achievement. Yet, within the same class, individual students may vary significantly in how much homework improves their baseline performance. Plus, there is the fact that some students are simply more efficient at completing their homework than others, and it becomes quite difficult to pinpoint just what type of homework, and how much of it, will affect overall academic performance.

Over the last century, the amount of time that children and adolescents spend in school has greatly increased

Gender is also a major factor. For example, a study of US high school students carried out by Prof Gary Natriello in the 1980s revealed that girls devote more time to homework than boys, while a follow-up study found that US girls tend to spend more time on mathematics homework than boys. Another study, this time of African-American students in the US, found that eighth grade (ages 13-14) girls were more likely to successfully manage both their tasks and emotions around schoolwork, and were more likely to finish homework.

So why do girls seem to respond more positively to homework? One possible answer proposed by Eunsook Hong of the University of Nevada in 2011 is that teachers tend to rate girls’ habits and attitudes towards work more favourably than boys’. This perception could potentially set up a positive feedback loop between teacher expectations and the children’s capacity for academic work based on gender, resulting in girls outperforming boys. All of this makes it particularly difficult to determine the extent to which homework is helping, though it is clear that simply increasing the time spent on assignments does not directly correspond to a universal increase in learning.

Can homework cause damage?

The lack of empirical data supporting homework in the early years of education, along with an emerging trend to assign more work to this age range, appears to be fuelling parental concerns about potential negative effects. But, aside from anecdotes of increased tension in the household, is there any evidence of this? Can doing too much homework actually damage children?

Evidence suggests extreme amounts of homework can indeed have serious effects on students’ health and well-being. A Chinese study carried out in 2010 found a link between excessive homework and sleep disruption: children who had less homework had better routines and more stable sleep schedules. A Canadian study carried out in 2015 by Isabelle Michaud found that high levels of homework were associated with a greater risk of obesity among boys, if they were already feeling stressed about school in general.

It is also worth noting that too much homework can create negative effects that may undermine any positives. These negative consequences may not only affect the child, but also could also pile on the stress for the whole family, according to a recent study by Robert Pressman of the New England Centre for Pediatric Psychology. Parents were particularly affected when their perception of their own capacity to assist their children decreased.

What then, is the tipping point, and when does homework simply become too much for parents and children? Guidelines typically suggest that children in the first grade (six years old) should have no more that 10 minutes per night, and that this amount should increase by 10 minutes per school year. However, cultural norms may greatly affect what constitutes too much.

A study of children aged between 8 and 10 in Quebec defined high levels of homework as more than 30 minutes a night, but a study in China of children aged 5 to 11 deemed that two or more hours per night was excessive. It is therefore difficult to create a clear standard for what constitutes as too much homework, because cultural differences, school-related stress, and negative emotions within the family all appear to interact with how homework affects children.

Should we stop setting homework?

In my opinion, even though there are potential risks of negative effects, homework should not be banned. Small amounts, assigned with specific learning goals in mind and with proper parental support, can help to improve students’ performance. While some studies have generally found little evidence that homework has a positive effect on young children overall, a 2008 study by Norwegian researcher Marte Rønning found that even some very young children do receive some benefit. So simply banning homework would mean that any particularly gifted or motivated pupils would not be able to benefit from increased study. However, at the earliest ages, very little homework should be assigned. The decisions about how much and what type are best left to teachers and parents.

As a parent, it is important to clarify what goals your child’s teacher has for homework assignments. Teachers can assign work for different reasons – as an academic drill to foster better study habits, and unfortunately, as a punishment. The goals for each assignment should be made clear, and should encourage positive engagement with academic routines.

Parents should inform the teachers of how long the homework is taking, as teachers often incorrectly estimate the amount of time needed to complete an assignment, and how it is affecting household routines. For young children, positive teacher support and feedback is critical in establishing a student’s positive perception of homework and other academic routines. Teachers and parents need to be vigilant and ensure that homework routines do not start to generate patterns of negative interaction that erode students’ motivation.

Likewise, any positive effects of homework are dependent on several complex interactive factors, including the child’s personal motivation, the type of assignment, parental support and teacher goals. Creating an overarching policy to address every single situation is not realistic, and so homework policies tend to be fixated on the time the homework takes to complete. But rather than focusing on this, everyone would be better off if schools worked on fostering stronger communication between parents, teachers and students, allowing them to respond more sensitively to the child’s emotional and academic needs.
