In the fall of 2003, I was extremely fortunate to have two very gifted students in a calculus class, Doug Anewalt and Paul Lee, who had a deep interest in both mathematics and computer science. I had integrated various exercises with Exploring Small Groups (ESG) into my textbook, An Introduction to Algebraic Structures. Since ESG did not interface with the new Windows environment, I thought I should see what these two talented students could do to enhance the learning of group theory.

Even though they were only freshmen at the time and didn't even know what a group was, they courageously agreed to work with me on this project. I told them it had to be user-friendly so that no one would have to take a workshop to learn how to use it, and visually appealing and colorful, since I thought the color might stimulate those students who have trouble seeing the inherent beauty of group theory. When you review the software, you will see what a marvelous job Doug and Paul have done in accomplishing these goals.


Bios

Nancy Rodgers is a professor of mathematics at Hanover College. Her book, Learning to Reason, was published by John Wiley & Sons in 2000. The game space she designed for it received a Merit Award from the Society for Technical Communications. She developed the educational software GroupsUnlimited for her book, An Introduction to Algebraic Structures, which is scheduled for publication in 2016. She co-produced In the Footsteps of Newton, an educational documentary that follows seven Hanover College students as they take a life-changing journey to find out how a farm boy from humble origins ends up buried among kings in Westminster Abbey. It was broadcast on PBS WFYI and screened at Math Fest in Madison WI and the Utopia Film Festival in Greenbelt MD. She won an Aegis Award as co-producer of the documentary, William Blake: Inspiration and Vision. She is the founder and publisher of Springwood Press. Before Hanover, she worked for Crosfield Composition Systems, an international newspaper software company, in Sweden and England and taught at Kent State University for ten years.

Paul Lee went to graduate school in computer science at the University of Virginia and now works as a programmer in California. He graduated from Hanover College in 2007 with a double major in mathematics and computer science, and a minor in physics. He received the Distinguished Award in Computer Science and Yarnelle Mathematics Prize. As chair of the Association of Computing Machinery (ACM) student chapter, Paul organized various campus events to get more students interested in computer science. He started the Math Club at Hanover and served as its first president. He also was a member of the Hanover Martial Arts Club, Anime Club, BASIC, Concert Band, Chamber Orchestra, and Mortarboard. 

Doug Anewalt went to graduate school in mathematics at the University of Kentucky and now teaches in Indianapolis. In the spring of 2007 he graduated summa cum laude from Hanover College with a double major in mathematics and computer science. His awards include the Yarnelle Mathematics Prize, Morse Mathematical Award, Distinguished Award in Computer Science, and Alpha Lambda Delta Award. He was a member of the varsity tennis team for four years and earned all-conference honors the past three years. He was actively involved in intramural volleyball, softball, and basketball, and was the defending floor hockey champion for two years.

We would like to thank Ladnor Geissinger, professor of mathematics at the University of North Carolina, for developing his innovative program, Exploring Small Groups (ESG), in 1989 which was the inspiration for our program.

We would like to thank Ellen J. Maycock, Associate Executive Director of the American Mathematical Society, for her book, Laboratory Experiences in Group Theory, MAA, 1996, which introduced us to the pedagogical benefits of using ESG in an abstract algebra class.   

We would like to thank Edward Keppelmann, professor of mathematics at the University of Nevada, for giving us permission to use tables from his software program, Finite Group Behavior, in the GU Group Library.

We would like to thank the Faculty Development Committee at Hanover College for their generous support of the development of this program.
