T H E revolution in foreign language teaching that is currently sweeping away traditional methods and approaches was surveyed by B. Libbish, editor of Volume One of this series (1964), in his Introduction. He concluded: "There is still much to be done. We are merely on the fringe of the new procedures." Volume Two, which offers twelve articles by pioneers in modern language teaching, is an attempt to show some of the steps that have been taken in the development of new procedures. Yet we can but echo: "There is still much to be done."
