Editorials
With this issue the Mathematics Teacher becomes the official journal of the National Council of Teachers of Mathematics. Its editorial policy will be characterized, it is hoped, by a broad, generous disposition to give approval and publicity to all constructive efforts to improve the teachings of mathematics. In this period of reconstruction, when the whole problem of the selection and organization of the materials in mathematical curricula is so vital, and, to date, so much a matter of a priori thinking, we can ill afford to try to negative the tentative solutions of those whose judgments differ from ours. The Teacher represents no one faction, no one “school of thinking.” Its columns shall constitute a forum through which the positive claims of the advocates of any “prescription” of mathemathical material may be discussed. We have a deep conviction that only after clear a priori thinking has been supplemented by long and careful experimentation, can any purported solution of our curriculum problem assert serious claims for wide acceptance and adoption.
