He taught for six years at Occidental College, where he won the college-wide Linda and Tod White Teaching Prize in his fifth year. At Occidental he took a leading role in curriculum design of both service courses and the major curriculum, and created accessible descriptions for previously undocumented department policy. He supervised three undergraduate research projects, which are part of a manuscript in preparation for publication, and two undergraduate honors theses. More recently he has been working on the use of open educational resources and alternative methods of assessment, at both Occidental and GWU. He is helping lead a switchover of the GWU service courses to an open-source textbook, assisting other faculty with conversion to an OER online homework system, and conducting a pilot study of mastery grading in intro-level math courses.
