By 1920, there were just a few changes to the curriculum in place when Cajori left. The History and Logic of Mathematics became the Teachers' Course reflecting the emphasis on history and methods appropriate for secondary education. Professor Albright added a course on the mathematical theory of investments and Professor Sisam taught statistical methods.
Economics was taught at the college and,
in fact, their curriculum included statistics and investment courses
covering mathematical topics.
There has always been an interplay between Economics and Mathematics,
and in 1920 the mathematics department decided to give their own
spin to some of the more mathematically oriented economics courses.
By 1926, there were two
statistic courses in the mathematics curriculum and both Lovitt
and Belschner (1927)
taught them. Albright's investment course remained
in the curriculum until 1960.
In 1928, at the more advanced end of the curriculum, Professor Sisam designed a course titled Functions of a Complex Variable. This course stayed in the curriculum until Sisam left in 1948; it was then dropped for awhile reappearing in the mid sixties.
Also in 1928, the college began organizing disciplines into three divisions; the main curricular reorganization occured in 1932, but it was foreshadowed a few years earlier. Students at this time selected a major field and two minor fields of study.
