Presentations on MathObjects
In the summer of 2006 at the MathFest in Knoxville Davide Cervone introduced the MathObjects extension to the PG language. This allows you to write code using objects that more closely mimic mathematics constructs as we usually think about them. This code is easier to read and to maintain and is now the preferred way to write problems. (Of course there are still many problems written without using MathObjects, but when creating new problems use a "MathObjects" problem as a model if at all possible. :-)
Notice that the talk uses WeBWorK itself as a presentation tool.
Davide gave a more in depth talk (More on math objects ) on the properties of MathObjects at the AIM webwork workshop in August 2007
