The Noyce Track 3: Master Teaching Fellowship project aims to serve the national need of preparing and retaining highly-qualified STEM teachers to support K–12 education and workforce development in response to the rapid growth of domestic microelectronics and semiconductor industries. Additionally, this project plans to support 15 practicing STEM teachers in science, technology, engineering, and mathematics by offering leadership development, mentoring, and opportunities to co-design and implement locally relevant STEM initiatives. The proposed project components are positioned to enable high-achieving practicing teachers to become STEM teacher leaders with the capacity to engage students in innovative STEM learning experiences and to strengthen educational pathways that align with the evolving needs of regional microelectronics ecosystems in Idaho and New York. This project at Boise State University and the University of Rochester includes partnerships with rural and urban high-need school districts in Idaho and New York; the Industrial Associates Program at the University of Rochester; the Microelectronics Education and Research Center at Boise State University; and nonprofit organizations such as the Idaho STEM Action Center, the Idaho Rural Schools Association, and The Story Collider. Project goals include preparing and retaining 15 STEM teacher leaders over five years in science, technology, engineering, and mathematics to support the emerging microelectronics and se
