I love teaching - that's one of the main reasons I am at Centre College. You can reach my course web pages via the following links:

In 2009 I was honored to receive one of Centre's teaching awards, which included a request for a statement of my teaching philosophy. Here's what I shared:

My teaching philosophy is a blend of idealism and pragmatism.

On the idealistic side, I approach my classroom as a place of transformation. I am helping our students build better brains and, in doing so, they leave my classes changed in positive ways and more able to make a difference for good in our world. I am hopeful that my students will come to appreciate and respect mathematics, and remain eager to learn more. As Arnold Ostebee and Paul Zorn wrote in the preface of a textbook: "Here's another reason to study calculus: because calculus is among our species' deepest, richest, farthest-reaching, and most beautiful intellectual achievements." The same can be said of many other areas of mathematics. What a privilege I have to share such wisdom and beauty with my students! I also seek to have fun in the classroom. I believe that my love for math and my own positive, transformational experiences of mathematics enable opportunities for my students loving, playing with, and being changed by mathematics.

On the pragmatic side, I recognize that not all my students share this affection for mathematics (at least not yet!). In fact, many of my students may think of my class as their least favorite, with mathematics stirring up strong emotions of fear, anger, and despair. Or worse yet, apathy. And so, I assign and collect daily homework and quizzesódespite all the time the grading consumesóbecause such exercises require my students to spend time with mathematics between classes and so enable their learning. Similarly, I always hold study sessions the evening before an exam, because I know that is when many of my students will be studying, and I can help them focus and learn that much more. Finally, I try to encourage the self-doubting students in their successes. I tell them that hard work trumps natural ability and I urge my students to intentionally invest in themselves in their efforts to reap the rewards of learning mathematics.

One more thing: the picture at the top of this webpage was taken on Mykonos Island, Greece on January 22, 2012. I was there with Dramatic Arts Professor Matthew Hallock and 28 Centre students for HUM 254: Drama and Math in Ancient Greece. We plan to go back in January 2015, if you might be interested?!

Personal Information

I am married to Julie Eberhardt McAllister. We met each other at Virginia Tech where Julie earned her B.S. in Industrial and Systems Engineering. Julie has also earned a masters degree in theology at St. Michael's College in Burlington, Vermont and a masters degree in Health Administration at the University of Kentucky.

We have three children - Benjamin Martin, Daniel John, and Ella Margaret - and three pets - a dog and two cats. Our family enjoys soccer, walking, kayaking, festive holidays, and good friends. We're also in the middle of gutting and rebuilding a 100 year old house -- I've learned why most houses are built by teams of people! The rest of our family resides throughout the Southeast in Alabama, Maryland, Ohio, and West Virginia.

Some of my hobbies include running, biking, weight-lifting, playing guitar, woodworking, doing yardwork, watching movies, and playing with my kids. Some more biographical information is available on the mathematics department webage at: Mathematics Biographies.
