Graduate students who serve as teaching assistants are a critical part of STEM (science, technology, engineering, mathematics) education and research at large universities in the U.S. Yet just like faculty, graduate students are not immune to the publish or perish paradigm, which can compete with one's dedication to teaching. While in recent years many STEM faculty members have become aware of how well undergraduates can assist instructors in their teaching, many, if not most, university faculty still teach in traditional settings, where graduate students are the norm and use of undergraduates is a completely unexploited opportunity. Undergraduates can serve as effective teaching assistants and may bring unique skills and experience to undergraduate instruction not held by graduate students. Undergraduate teaching assistants (UTAs) can provide additional support for reformed practices, which raise student learning. Based on cost, prior experience and success as students in same course, and shared vision with professors, a number of institutions have initiated UTA programs and reported increased student learning. The audience of this paper is faculty who are not familiar with the use of UTAs in university teaching, and the purpose is to review the literature on UTAs, contrast the contributions of UTAs and graduate teaching assistants, and examine the potential value of UTAs in undergraduate education.
