This project aims to serve the national interest by promoting best practices in introductory experimental physics. This Level 2 Institutional and Community Transformation project will support introductory physics lab instructors to redesign their labs according to strategies proven by physics education research. Physics labs focused on developing experimentation skills improve students' critical thinking ability and views on experimentation compared to labs focused on reinforcing lecture concepts. These impacts are positive for students. This project will create and sustain an Introductory Physics Labs Institute to create community and resources for introductory physics labs. The significance of this project is in developing instructor expertise, implementing educational innovations, and adapting existing educational innovations for specific teaching and learning environments. The project will also disseminate teaching and learning innovations broadly. The project will build and support an expansive community of passionate lab instructors eager to implement effective, experimentation-focused labs at their institutions. Lab instructors will contribute their instructional resources to an online resource created by this project, the Introductory Physics Labs Portal, modeled on existing highly successful portals developed by the American Association of Physics Teachers. The project applies an asset-based agentic paradigm for faculty change. The scope of this project includes
