As we think about the future of education, we need to sharpen our understanding of what education is and what educators do. Education is often compared to two other industries upended by the Internet: journalism and publishing. This is a serious error.
Education is not the transmission of information or ideas. Education is the training needed to make use of information and ideas. As information breaks loose from bookstores and libraries and floods onto computers and mobile devices, that training becomes more important, not less.
But the core task of training minds is labor-intensive; it requires the time and effort of smart, highly trained individuals. We will not make it significantly less time-consuming without sacrificing quality. And so, I am afraid, we will not make that core task significantly less expensive without cheapening it.
