This document discusses conceptualizing collaborative participation and engagement in open educational resource (OER) communities. It examines OER typologies and communities, how OER are used and reused, and how they can improve education by making resources visible and accessible to communities. It also looks at categories of OER providers like institutions and communities, potential tensions around OER, and how collaboration and knowledge exchange can occur through communities of improvement and practice that engage faculty, tutors, and learners.
