The American colleges were naturally somewhat slower than some of those of Europe in adapting themselves to the changed conditions, but the rapidity of the changes in our country may be inferred from the fact that in the first half of the nineteenth century Harvard placed in comparatively short succession three mathematical subjects on its list of entrance requirements; viz., arithmetic in 1802, algebra in 1820, and geometry in 1844. Although Harvard had not established any mathematical admission requirements for more than a century and a half after its opening, she initiated three such requirements within half a century. It is interesting to note that for at least ninety years from the opening of Harvard, arithmetic was taught during the senior year as one of the finishing subjects of a college education.[[7]]
The passage of some of the subjects of elementary mathematics from the colleges to the secondary schools raised two very fundamental questions. The first of these concerned mostly the secondary schools, since it involved an adaptation to the needs of younger students of the more or less crystallized textbook material which came to them from the colleges. The second of these questions affected the colleges only, since it involved the selection of proper material to base upon the foundations laid by the secondary schools. It is natural that the influence of the colleges should have been somewhat harmful with respect to the secondary schools, since the interests of the former seemed to be best met by restricting most of the energies of the secondary teachers of mathematics to the thorough drilling of their students in dexterous formal manipulations of algebraic symbols and the demonstration of fundamental abstract theorems of geometry.
Relation of mathematics in secondary schools and college
Students who come to college with a solid and broad foundation but without any knowledge of the superstructure can readily be inspired and enthused by the erection of a beautiful superstructure on a foundation laid mostly underground, with little direct evidence of its value or importance. The injustice and shortsightedness of the tendency to restrict the secondary schools to such foundation work would not have been so apparent if the majority of the secondary school students would have entered college. As a matter of fact it tended to bring secondary mathematics into disrepute and thus to threaten college mathematics at its very foundation. It is only in recent years that strong efforts have been made to correct this very serious mathematical situation.
Much progress has been made toward the saner view of letting secondary mathematics build its little structure into the air with some view to harmony and proportion, and of requiring college mathematics to build on as well as upon the work done by the secondary schools. The fruitful and vivifying notions of function, derivative, and group are slowly making their way into secondary mathematics, and the graphic methods have introduced some of the charms of analytic geometry into the same field.
This transformation is naturally affecting college mathematics most profoundly. The tedious work of building foundations in college mathematics is becoming more imperative. The use of the rock drill is forcing itself more and more on the college teacher accustomed to use only hammer and saw. As we are just entering upon this situation, it is too early to prophesy anything in regard to its permanency, but it seems likely that the secondary teachers will no more assume a yoke which some of the college teachers would so gladly have them bear and which they bore a long time with a view to serving the interests of the latter teachers.
As many of the textbooks used by secondary teachers are written by college men, and as the success of these teachers is often gauged by the success of their students who happen to go to college, it is easily seen that there is a serious temptation on the part of the secondary teacher to look at his work through the eyes of the college teacher. The recent organizations which bring together the college and the secondary teachers have already exerted a very wholesome influence and have tended to exhibit the fact that the success of the college teacher of mathematics is very intimately connected with that of the teachers of secondary mathematics.
While it is difficult to determine the most important single event in the history of college teaching in America, there are few events in this history which seem to deserve such a distinction more than the organization of the Mathematical Association of America which was effected in December, 1915. This association aims especially to promote the interests of mathematics in the collegiate field and it publishes a journal entitled The American Mathematical Monthly, containing many expository articles of special interest to teachers. It also holds regular meetings and has organized various sections so as to enable its members to attend meetings without incurring the expense of long trips. Its first four presidents were E. R. Hedrick, Florian Cajori, E. V. Huntington, and H. E. Slaught.
An event which has perhaps affected the very vitals of mathematical teaching in America still more is the founding of the American Mathematical Society in 1888, called the New York Mathematical Society until 1894. Through its Bulletin and Transactions, as well as through its meetings and colloquia lectures, this society has stood for inspiration and deep mathematical interest without which college teaching will degenerate into an art. During the first thirty years of its history it has had as presidents the following: J. H. Van Amringe, Emory McClintock, G. W. Hill, Simon Newcomb, R. S. Woodward, E. H. Moore, T. S. Fiske, W. F. Osgood, H. S. White, Maxime Bôcher, H. B. Fine, E. B. Van Vleck, E. W. Brown, L. E. Dickson, and Frank Morley.
