'New' ideas in old contexts: Warren Colburn and mathematics curriculum and teaching

As in the case with many systems and institutions, American public education is constantly in flux. The difference with education, as opposed to other institutions like business and law, is that a historical examination of these particular institutions indicates that, rather than changing completely, education has a tendency to oscillate between similar theories on matters such as how to improve student learning, how to increase student achievement, and how to craft a curriculum that connects with every student. In the field of mathematics, the sides are clearly drawn and have been in existence at least since the early 20th century. Here, Cooper and Null focus on the works of Warren Colburn, a forgotten mathematics educator who was instrumental in the development of the inductive approach.
