Teaching scientific knowledge doesn't improve scientific reasoning

Blogging on Peer-Reviewed ResearchOn Tuesday, I wrote a short essay on the rightful place of science in our society. As part of it, I argued that scientific knowledge is distinct from the scientific method – the latter gives people the tools with which to acquire the former. I also briefly argued that modern science education (at least in the UK) focuses too much on the knowledge and too little on the method. It is so blindsided by checklists of facts that it fails to instil the inquisitiveness, scepticism, critical thinking and respect for evidence that good science entails. Simply inhaling pieces of information won’t get the job done.

This assertion is beautifully supported by a simple new study that compared the performance of physics students in the USA and China. It was led by Lei Bao from Ohio State University who wanted to see if a student’s scientific reasoning skills were affected by their degree of scientific knowledge. Does filling young heads with facts and figures lead to a matching growth in their critical faculties?

Fortunately for Bao and his team of international researchers, a ready-made natural experiment had already been set up for them, in the education systems of China and the US. Both countries have very different science curricula leading to different levels of knowledge, but neither one explicitly teaches scientific reasoning in its schools. If greater knowledge leads to sharper reasoning, students from one country should have the edge in both areas. But that wasn’t the case.
