The "OER Guide for WR 227 Instructors: Using Open Educational Resources (OERs) in WR 227 Courses" aims to help instructors make sense of and sort the massively decentralized and varying content of existing OERs available to support technical and professional writing courses. This guide is intended as a resource for introductory technical writing course instructors to adapt an existing course to integrate OER resources, or, to build a new course with all-OER student resources. This guide was developed for the specific use of WR 227 instructors at Portland State University and across Oregon; however, the material in the guide or its presentation is not tied to any particular course and is therefore also useful for instructors of introductory technical writing and professional writing courses more broadly.
