Creating Interactive Graphics for Mathematics Education Utilizing KETpic

摘要

In teaching mathematics, there are instances when we need to graphically present mathematical concepts and solid figures to clarify students’ understanding of them. For the last few years, we have been creating graphics that illustrate these various concepts dynamically through careful utilization of KETpic. Examples we will look at include an interactive graphic developed to clearly illustrate the line of intersection of two solid surfaces. In this case, we can easily show the cross-section of the intersection following the cut. A second example is of an interactive graphic produced in order to dynamically present the correspondence relation between the z?plane and w?plane in a complex function w = f(z). Here, by using the navigation buttons embedded in the graphic, we can demonstrate how the regions on the w?plane change in relation to the z?plane. Other graphics we have produced will also be introduced.
