• WeBWorK is a highly successful program designed to deliver Internet-based mathematics homework to students. Designed by Professors Michael Gage and Arnold Pizer at the University of Rochester with support from the National Science Foundation, this program was introduced at Radford University in college algebra and has been integrated into several other courses. The work at Radford University was initially supported by the National Science Foundation Grant DUE project 0125586. Click Jacksonville presentation to see a presentation involving WeBWorK.

• Applications of Abstract Algebra with Maple and MATLAB, Second Edition, a textbook from CRC Press written with Dr. Richard Klima of Appalachian State University and Ernest. L. Stitzinger of North Carolina State University. This text explores common abstract algebra applications such as block designs, error correcting codes, cryptography, and Polya enumeration  with relevant programs, examples, and exercises written for Maple V and MATLAB.
