Project CORACORA stands for Community of Online Research Assignments. It is an open educational resource (OER) for librarians, faculty, and other educators. 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 site contains multiple, reliable and reproducible research assignments that do not live as isolated entities, but are enhanced by user feedback in order to build a rich corpus of best practices. There is also a Teaching Toolkit featuring a wide range of resource types including pedagogy/theory, assessment, classroom activities, technology tips, subject guides, citation tools, and information literacy tutorials.
