This document discusses the formation of Open Educational Resource (OER) user groups in Washington state to promote collaboration around OER adoption and implementation among K-12 educators. It provides several examples of proposed user groups that would bring together teachers from different districts to review, adapt, and share OER materials in areas like mathematics, English language arts, social studies and for small, rural schools. The goals are to define best practices, champion OER distribution and implementation, and address challenges like developing shared resources and aligning district-created materials with open licensing.
