Resumen
It is argued that sustainable development makes best sense as a social learning process that brings tangible and useful outcomes in terms of understanding and skills, and also reinforces the motivation and capability for further learning. Thus, there are always balances to be struck between a broad-based, wide-ranging education and a more specialist one; between a focus on ideas themselves, and on their application in social or economic contexts; and between keeping ideas separate, and integrating them. This paper will explore the nature of such balances, and the issues to bear in mind when striking them, focusing on schools, university and college contexts within the United Kingdom.
