The best way to boost the economy is the best way to improve the lives of disadvantaged students

What if we had an opportunity to double the size of the tourism industry, or to quadruple the size of the beef industry, or to boost the economy by more than any of the presently proposed tax switches?

What if we could do it while permanently improving the lives of disadvantaged young people?

We surely wouldn’t let it slip away.

Yet we do every day while we fail to address the gap in school achievement between between rural, regional and remote children and their city counterparts.

New estimates

In a report for UNSW Gonski Institute on Education^[1] launched on Monday, Jessie Zhang and I estimated the size of the gap. We also document its causes, and outline what the research in the United States and Europe tells us about ways to narrow it.

Over the past decade education research has undergone a transformation with the use of large-scale randomised controlled trials to determine what works.

It isn’t easy because correlations can be misleading. If, for instance, we discover that women who eat more fish during pregnancy tend to have children who perform better in primary school, we might be tempted to conclude its the Omega-3 fatty acids that do it.

It’s hard to work out what works

But women who eat a lot of fish tend to be wealthier. It might be that extra wealth – and the educational resources it affords – that are driving the better performance.

Who knows? Increasingly, the social scientists who construct randomised trials do.

Using techniques from pharmaceutical and other trials they are getting good at zeroing in actual causes and ignoring mere correlations.

What works the most, according to the US studies, are high-dose-small-group tutoring, balanced incentives for students, managed professional development for teachers, smaller class sizes, and a culture of high expectations.

Some of what works is as good as free

Some of these measures are expensive, some are almost free.

All have been shown to have a high return in the US.

There are good reasons to believe they could be highly effective in rural, regional and remote Australia.

It would be worthwhile conducting our own randomised controlled trials in our own cultural and educational environment to be sure.

The prize is big

In our report we translate the differences in school achievement to the differences in human capital and eventually lifetime earnings.

This puts the economic benefit of closing the urban-non urban gap at A$56 billion — about 3.3% of Gross Domestic Product.

Massive though that number is, it is both narrow and an underestimate. It focuses purely on how better skills can translate into better wages.

It doesn’t consider how the benefits of better skills can spread and multiply throughout the economy. Nor does it consider the benefit of revitalising country towns, or the benefits of better physical and mental health.

Bigger than we can measure

Most of all, it doesn’t capture the truth that bridging this achievement gap would provide a world of expanded opportunities for millions of young Australians, and give them the chance to live out their full potential.

Bridging the urban non-urban achievement gap between is easier said than done, but the potential benefits from it to both the economy and the lives of Australians who would become more able to achieve their full potential are too big to ignore.
