Why we should (carefully) consider paying kids to learn

Paying students to do homework can actually improve their grades.

Over the past 15 years, we’ve seen a decline in the performance of Australian school students on international tests. On the Programme for International Student Assessment (PISA), Australia ranks a disappointing 20th in mathematics and 12th in reading. However you feel about standardised tests like NAPLAN and PISA, it certainly isn’t good news that we’re falling behind internationally.

Over the same period, there has also been a revolution in education research through the use of randomised controlled trials to assess the effectiveness of different education policies. All manner of things have been tried – everything from smaller class sizes to intensive tutoring. And now paying kids to learn.

My coauthors and I did just that in two sets of experiments in Houston, Texas and Washington, D.C. We found if kids are paid for things such as attendance, good behaviour, short-cycle tests, and homework they were 1% more likely to go to school, committed 28% fewer behavioural infractions, and were 13.5% more likely to finish their homework.

This led to a big increase in kids performing at a proficient level in mathematics and reading. This cost money – we distributed roughly AU$7 million in incentives to 6,875 kids. But measured financially, the approach where we gave students money for a number of things (such as behaviour, attendance and academic tasks) produced a 32% annual return on investment.

Our experiments

In Houston, we paid 1,734 fifth graders to do maths homework problems. We paid the parents too, if their child did their homework.

Some 50 schools were given educational software that fit in with the curriculum. Half (25) of those schools were randomly selected to be in the “treatment group”. This group of school kids got AU$2.80 per homework problem they mastered. Parents of the children got AU$2.80 per problem mastered, and teachers were eligible for bonuses of up to AU$14,000.

The 25 control schools got the identical educational software and training, but no financial incentives.

This randomised controlled trial allows for a simple test of the effect of financial incentives. This works because there are a large number of students in both the treatment and control group, and because they were randomly assigned. Differences in other factors like innate ability, home background, or parental involvement average out.

So to understand the true, causal effect of the cash incentives on test scores we can just look at the difference in average test scores between the treatment and control kids.

This is the same principle underlying pharmaceutical trials. For example, some patients might get heart medication, while others get a placebo (a sugar pill). Researchers then look at the difference in heart functioning to figure out whether the medication works.

This approach is the gold standard for understanding the true effect of an intervention – in medicine, economics, or education.

The financial incentives we used in Houston led to children doing lots more homework, and to a fairly large increase in performance on standardised maths tests. But there was an almost equal offsetting decline in performance on reading tests.

The children responded to the incentives all right – by shifting their efforts from reading, which they didn’t receive incentives for, to maths.

The most able 20% of students, based on their prior-year test scores, did way better in maths and no worse in reading. Incentives for the least able 20% of students were a disaster. They did lots more maths problems, did no better on maths tests, and far worse on reading tests.

By contrast, in Washington D.C. we provided incentives for sixth, seventh and eighth grade students on multiple measures, including: attendance, behaviour, short-cycle assessments, and two other variable measures chosen by each school. This led to a 17% increase in students scoring at or above proficiency for their grade in maths and a 15% increase in reading proficiency.

Is it ethical to pay kids to learn?

Paying children to study and behave might sound radical, or even unethical. Yet we provide incentives to kids all the time. Most parents use a combination of carrots and sticks as motivation already, such as screen time or treats.

A legitimate concern is that cash incentives might affect intrinsic motivation and turn learning into a transaction rather than a joy. The evidence from our study showed intrinsic motivation actually increased.

Perhaps the harder question is whether it’s ethical to use an approach that won’t help less advantaged students perform better and develop a love of learning.

The path forward

Nearly two decades of research in the US using randomised control trials has identified the positive causal effect of a range of interventions. These include high-dose tutoring, out-of-school and community-based reading programs, smaller class sizes, better teachers, a culture of high expectations and, yes, financial incentives.

In Australia, we should be open minded and look at the evidence. This will involve carefully designed randomised trials in Australian schools to determine what really works, and what the return on investment is.The Conversation

  • My sister did this with her kids and it backfired. They were paid $50 for an A, and I don’t remember the rest of the breakdown. The kids were never taught how to study, and there was all this constant pressure of “make sure you do well so you can get $50″. In the end, none of them ever studied because it was too much pressure. They all went on to uni and again, no study because they hated learning – the joy was sucked out of it when they were in primary school. I wouldn’t pay my kids at all. We promote the joy of learning and how cool it is to know stuff.

  • Interesting concept. I guess it gives them motivation to do well. But there’s plenty of things in life we need to do without any reward and I don’t know if it’s setting kids up for unrealistic expectations about life

  • I don’t think I agree with paying kids to do their homework is a good idea, but I do think getting paid to do chores is something we will do when my son is older so he learns how to do basic chores etc but also how to save and earn money

  • Interesting view. However I don’t feel for paying my kids to do their homework or normal chores which are part of life.

  • I feel like paying them or creating some sort of reward chart can be good as it allows them to see that positive behaviour receives rewards and shows them how to work for it as opposed to being handed everything in life

  • I don’t really think it’s ethical or should be done however it would be a good incentive to many students and their families.

  • Very interesting to look at the results of these experiments. I’ve never tried something like this, but maybe with some kids it would bring evident results.

  • I know a child who wants an expensive item. He has been told he has to “earn” it. Helping around the house without moaning about it,. do as he is asked to do without arguing, put his clean clothes away – not toss them on the floor. good behaviour, go into class at school on time – not muck around – he is dropped off at school in plenty of time.
