Giving physics exams in a centralized computer-based testing lab

I will describe the use of a computer-based testing center in teaching introductory physics at an urban public university. The center is maintained by the university’s IT services and is open to all departments, though use is heaviest in mathematics and the natural sciences. At present, approximately 130 students can take exams concurrently, and the center is open 55 hours/week. Exams are scheduled, administered, and graded through the learning management system (Canvas at present). Faculty have substantial flexibility in setting exam durations and rules regarding notes, calculators, etc. This talk will describe the creation and maintenance of the center but will focus on the substantial pedagogical and logistical benefits of the system, including improved exam security, and scheduling flexibility. It will also note some drawbacks and potential improvements.
