CORA (Community of Online Research Assignments) is a repository of open access research assignments for faculty and librarians.
From their website:
It is intended to be a collaborative space for adapting and experimenting with research assignments and sharing the success or lessons learned so that others may benefit. The database will contain multiple, reliable and reproducible research assignments that will not live as isolated entities, but are enhanced by user feedback in order to build a rich corpus of best practices.
What assignments are appropriate for sharing in CORA? A research assignment is anything that requires students to engage with information resources in a critical or reflective way. This most often includes finding, retrieving, analyzing and evaluating, using and integrating, or organizing the information in order to produce new knowledge.
