Fei Xue joined the College of Arts and Sciences in 2008. His students usually call him Professor X, and his research includes differential and difference equations, dynamical equations on time scales, and a little bit of probability. He is a member of the following organizations: Mathematical Association of America (MAA), International Society of Difference Equations (ISDE), and the Society for Advancement of Chicanos/Hispanics, and Native Americans in Science (SACNAS).


Pedagogical Techniques:

  • Flipping the Classroom

Undergraduate Research:

I have worked with a few students on the project Mixed Probability Distribution on Time Scales. We tried to set up some distributions on time scale which include both discrete and continuous domain.

Pedagogical Research

I am a Co-PI on the NSF grant Supporting and Sustaining Scholarly Mathematics Teaching (S^3MT), which was funded for $583,525 in 2017. This project is to develop a cadre of scholarly teachers who will teach flipped mathematics courses using active learning strategies, and who are committed to conducting and publishing research on the effectiveness of these pedagogical innovations.

I am a Senior Personal of the NSF grant Flipping Calculus (DUE#1245059), $172,136, from 2012 to 2016. We flipped all of our Calculus I sections and part of our Calculus II sections and did pedagogical research about our flipping.

About Me

Students usually call me Professor X. I enjoy teaching all kinds of mathematics. Besides math, I also love Chinese food, and Kong Fu movies and novels. But I am not good at either cooking nor Kong Fu.
