We explored the effectiveness of a flipped active learning pedagogy in a liberal arts mathematics course without video or interactive preparation. In both control and active learning classes, students were required to respond to a reading before class and take a quiz after class. During the active learning class, students worked together in groups on problems instead of listening to a lecture. This modest change in the in-class course structure showed that students were more willing to work with peers and ask questions of the instructor. Sources examined include common grade items as well as pre- and post-course attitude surveys.
