Old ideas give way slowly; for they are more than abstract logical forms and categories. They are habits, predispositions, deeply engrained attitudes of aversions and preference.
John Dewey, 1909
One of the most difficult tasks faced by the collective leadership of a nation is the design and maintenance of its schools. Leaders must decide what is to be taught, by whom, and who to teach. The membership of the teacher and the student groups, in turn, help determine how the subject matter is to be taught. The what, who, and how issues are further complicated by rapid changes in cultural values and priorities, political and economic issues and legal interpretations. These complications require strenuous policy discussions and often agonizing reappraisals as the nation’s political leaders interact with their constituents, including groups representing parents, educators, scientists and economists.
