This article describes a lesson plan that harnessed students' abilities to generate new teaching material by constructing country timelines. This involved "crowdsourcing," or the reliance upon task inputs from a large number of people to acquire information. The plan was motivated by an approach that conceives of learning as deriving from the joint activity of individuals with shared tools, and was geared toward promoting self-instruction alongside traditional lectures and exams. By relying on independent research and individual contributions to create a new teaching resource, the course facilitated strategic reading and peer learning and promoted a research-active learning environment. The experience encourages instructors to consider ways to use distributed learning in the classroom to make students both the producers and consumers of innovative content.
