Abstract: As physics instructors, we enjoy access to a variety of powerful instructional materials. Among them are classroom-tested inquiry-based laboratory curricula such as Physics by Inquiry [1] and Workshop Physics.[2] Unfortunately, such materials are often tested in conditions unattainable in introductory physics courses. In particular, the recommended instructor-student ratio tends to be larger than we can afford. This article describes a implementation of Physics by Inquiry in a liberal-arts physics class with 70 students and one instructor. I discuss the choices I made with the materials under these circumstances, describe the challenges that arose, and offer evidence that the course was fairly successful. Examples such as this one show that proven instructional materials can be put to good use even in circumstances that fall outside the tested conditions.
