The disciplined mind: What all students should understand.
"E.D. Hirsch calls for a sequenced K-12 curriculum in which students cover a large number of specified topics and concepts. . . [B]ut such literacy should come as a result of probing important issues and learning how to think about them in a disciplined way -- not as a consequence of mastering fifty or five hundred predetermined topics each year" (Gardner, 1999, p. 24).
