In her article Let's Bring Knowledge Back into Schools, Dr Elizabeth Rata is right to raise the issue of the role knowledge should play in the school curriculum. However, in the spirit of contestation she advocates, I would like to offer another perspective.
I agree that knowledge is fundamental to the school curriculum, just as it was 50 years ago. Intellectual development is a key purpose of education: that is, expanding students' minds (and horizons) by exposing them to the best possible knowledge. This idea goes back thousands of years, to a time when knowledge was thought of as a set of eternal truths.
Until recently it was possible to sustain this idea, while also recognising that knowledge is constantly being added to and changed. There is a huge body of literature on this. But the nature of knowledge has changed so much that we need to approach it differently.
Knowledge's exponential growth means that its traditional repositories (books, libraries, databases, academic journals, and the minds of individual experts) are far too small. As philosopher David Weinberger puts it, knowledge is now "too big to know". It exists, is created in, and is a property of networks. What knowledge is has changed.
This has major implications for how we should think about knowledge and intellectual development in schools. Students need knowledge, but the reasons they need it are now very different.
