Students in large-enrollment humanities courses need each other and frequent instructor feedback to learn complex concepts. This article details active learning techniques and assessments that we used to increase student communication, engagement, and learning in a large-enrollment, university-level Greek mythology course. We first inventory these techniques, including polling, structured-analysis activities, and two-stage exams, before demonstrating them at work with a concept central to our course, the oral palimpsest. We then assess their effect on student learning and show how expanded opportunities for communication and practice increased student comprehension of a difficult mythological concept.
