Sir Michael Barber, once a chief education adviser to Tony Blair, introduced one of the enduring modern myths about education when he quoted an unnamed South Korean policymaker in 2007, who said: “The quality of an education system cannot exceed the quality of its teachers.” This great teacher myth is often presented as a simple equation: great teaching gets great results. It’s a view that is widely held, tremendously appealing and completely wrong.
It sounds plausible. After all, children spend a lot of time at school and, collectively, we spend a great deal of money on education. By the time they are 16, children have been at school for 10,000 hours, the figure often said to be the minimum necessary to master a skill, and we spend around 5% of our GDP on education. Surely teachers must be the biggest factor in ensuring that all this effort is worthwhile?
David Cameron spoke “as a parent, not just a politician” when he recently introduced yet another plan to “deliver the best teachers” to “make Britain the best place in the world to learn”. “The best teachers” has become a common refrain in the ongoing narrative about schools, and it is very clear that many parents, pundits and politicians assume that the prime driver of attainment in schools is teachers themselves. So embedded is this idea, in fact, that when we hear that teaching is in crisis it is often assumed that this is because we don’t have enough good quality teachers. And often, we hear that by removing the bad teachers from the system, we will see improvements in future.
There is a huge problem with this view. Just how do you know who are bad teachers? For the past 40 years, a movement now known as “school effectiveness research” has promoted the idea that good teachers get good outcomes for children. Those who believe this also believe that, by removing bad teachers from our schools and replacing them with better ones, the crisis will be averted.
The key issue with this line of thinking is that teachers aren’t actually directly responsible for the learning in schools. Because, when it comes down to it, children are the ones who actually have to do the learning. Unfortunately, much to the frustration of every teacher – and parent – in the land, children don’t always do what they are told, or learn what we attempt to teach them. What’s more, children are by definition immature, and they don’t always know what is best for them. To further complicate matters, some children find school and learning easy and some don’t, often for reasons out of their, and our, control.
While teachers have to take responsibility for providing the very best circumstances in which to learn, any parent will know that children have their own ideas regardless of what we have to say about the matter. Children, sadly, are not all passively waiting to be filled up with facts and knowledge like empty vessels. The resistance of some children is legendary. Others overwhelm us with their eagerness to learn. But trying to teach anyone anything is tricky unless they actually want to learn, and are in a position to do so. What’s more, learning is hard work; it requires effort, repetition, practice, mental and physical exertion.
All this adds up to a picture of complexity ill served by the great teacher = great results myth. As is well known in the world of educational research, the variation in outcomes within any school is much, much larger than the variation between schools. In the same school, with the same teachers, some children learn a lot and others not so much, because while teachers teach, children are ultimately responsible for what they learn. There is lots of evidence that the vast majority of any child’s learning is due to their own efforts, not that of the school or of their teachers. In fact, academics such as Dylan Wiliam of the Institute of Education in London suggest that around nine times as much of a child’s measured learning outcomes can be attributed to the child rather than the difference their schooling has made.
Does that mean that teachers don’t matter? Of course it doesn’t. We need teachers who help children to get the most from their time in school. It does, however, mean that the common assumptions about what schools can achieve are based on a fallacy. Because learning is done by the child, and not by the teacher, and no education system can exceed the desire and capabilities of its children. The Korean policymaker was wrong. Schools are a very thin layer of icing on a very, very big cake. As highly skilled, dedicated and inspirational as the icing might be, in the end it is the cake that counts.
