Abstract: Small automatically assessed programming assignments are an often used resource for learning programming. Creating sufficiently large amounts of such assignments is, however, time consuming. As a consequence, offering large quantities of practice assignments to students is not always possible. CrowdSorcerer is an embeddable open-source system that students and teachers alike can use for creating and evaluating small automatically assessed programming assignments. While creating programming assignments, the students also write simple input-output -tests, and are gently introduced to the basics of testing. Students can also evaluate the assignments of others and provide feedback on them, which exposes them to code written by others early in their education. In this article we both describe the CrowdSorcerer system and our experiences in using the system in a large undergraduate programming course. Moreover, we discuss the motivation for crowdsourcing course assignments and present some usage statistics.
