Variability and Functionality in High School Mathematics
The subject of variation as a topic or possibly phase of mathematics is a very important one in the field of the secondary school. In this day, when so much is made of correlations within the general field of mathematics and with other allied fields of science, the study of variation brings out numerous interesting contacts and inter-relations for the pupil, thus impressing him with the great breadth of application of mathematics. Moreover, gradual development of the idea and use of variation establishes certain modes of thought applicable to matters not wholly mathematical and perhaps only relatively quantitative. The concept of variability or functionality is perhaps sufficiently far-reaching in scope and application, if properly studied and emphasized to serve more than any other idea or agency to tend to correlate or unify mathematics.
