Science Gateways are websites that make scientific resources (e.g., data, software, communications & collaboration tools) accessible to educators, students, and researchers, and have had large impacts on diverse fields in STEM. The QUBES platform was created as a Science Education Gateway, designed to broaden participation in scholarship around teaching and learning. The integrated nature of the QUBES four platform services (OER Library Access, Professional Learning, Partner Support, and Customizable Workspaces) makes it possible to collect, curate, and disseminate a diverse array of OER in a scalable and sustainable manner. Participants in this session will first be invited to share their view of the challenges to (1) bringing authentic scientific practice into the classroom, and (2) getting faculty to adopt and adapt use of OER. Following this discussion, we will give a brief overview of the QUBES four platform services and how they work together to address these challenges. In the second half of our session, participants will actively explore the central QUBES OER library, as well as multiple QUBES hosted sub-communities spanning varied disciplines that have leveraged OER as a key component of their community building and professional learning. During and after this hands-on exploration of the QUBES OER library, we will explore the many ways in which these community-based platform services integrate synergistically with the OER library, illustrating a holistic approach whereby community drives the OER engine, with the OER library itself drawing in new community members looking to use the material in their classrooms.
