Knowledge’s meaning is changing. Knowledge is no longer being thought of as ‘stuff’ that is developed (and stored) in the minds of experts, represented in books, and classified into disciplines. Instead, it is now thought of as being like a form of energy, as a system of networks and flows – something that doesthings, or makes things happen. Knowledge Age knowledge is defined—and valued—not for what it is, but for what it can do. It is produced, not by individual experts, but by ‘collectivising intelligence’ – that is, groups of people with complementary expertise who collaborate for specific purposes. These changes have major implications for our education system.
