Annotating puts you actively and immediately in a "dialogue” with an author and the issues and ideas you encounter in a written text. It's also a way to have an ongoing conversation with yourself as you move through the text and to record what that encounter was like for you.

The educational thought experiment I wish to undertake concerns curriculum. Not the specific content of curriculum, but the idea of curriculum, what any curriculum is, regardless of subject. Like Copernicus, I propose that for the sake of better results we need to turn conventional wisdom on it is head: let’s see what results if we think of action, not knowledge, as the essence of an education; let’s see what results from thinking of future ability, not knowledge of the past, as the core; let’s see what follows, therefore, from thinking of content knowledge as neither the aim of curriculum nor the key building blocks of it but as the offshoot of learning to do things now and for the future.
