1. The Association and Mathematical Education. The inclusion of a survey of mathematical education as a part of the semi-centennial celebration of the Mathematical Association of America is appropriate for many reasons. For example, the by-laws of the Association state that one of its objectives is "to assist in promoting the interests of mathematics in America, especially in the collegiate field . .. by conducting investigations for the purpose of improving the teaching of mathematics.... " In pursuit of its goals the Association has published the Carus Monographs of which the fifth, The History of Mathematics in America before 1900, by David Eugene Smith and Jekuthiel Ginsburg implicitly contains much of significance for the history of mathematical education in the country, especially at the college level. However, the past concern of the Association for mathematical education at the secondary level should neither be ignored nor allowed to lapse. It was particularly significant that the Association was mentioned on page one of the first volume of The Mathematics Teacher to be issued under the aegis of the National Council of Teachers of Mathematics. In 1921 the newly founded Council took over this journal from the Association of Teachers of Mathematics in the Middle States and Maryland. In the first issue of that year C. M. Austin, first president of the National Council, explained, in words which have a familiar ring, the needs and reasons for the founding of this new organization as follows: "During this same period (the previous ten years) high school mathematics courses have been assailed on every hand. So-called educational reformers have tinkered with the courses and they, not knowing the subject and its values, in many cases have thrown out mathematics altogether or made it entirely elective. Individual teachers and local organizations have made a fine defense to be sure, but there could be no concerted action. Finally, the Mathematical Association of America came to the rescue and appointed a committee to study the situation and to make recommendations. Already two valuable reports have been issued and others are in preparation. The pity of it is that this work, wholly in the realm of the secondary schools, should have to be done by an organization of college teachers. True, they have generously called in high school teachers to help, but the fact is that it remained for the college people to initiate the work. They could do it because they possessed a live, vigorous organization [1]. (The final report of the committee of the Association to which Austin referred was the famous "1923 report.") It is, I believe, altogether appropriate that this Association which is still live and vigorous should continue its interest in mathematical education, not only by recognizing it in the program of this, its semi-centennial, but also in the continuing concern showed by the work of its Committee on the Undergraduate Program which has a panel on teacher training. I was, therefore, greatly pleased when the Committee asked me to speak on
