This is a webinar hosted during Open Education week 2024 to showcase OER Commons, a repository for Open Educational Materials (OER) and 3 exciting textbook projects at UMass Dartmouth. Open Educational Materials are teaching and learning tools such as textbooks, tests/quizzes, and classroom activities that are available free of charge. At UMass Dartmouth we have an OER Creators program through which 3 open textbooks were created in 2023. The textbook projects are E-Commerce and E-Business by Shouhong Wang, A Guide to Analyzing Arguments in an Academic Setting by Jackie O’Dell, Joshua Botvin, and Yuan Zhang, and Women’s & Gender Studies by Catherine Gardner.
