How do we change undergraduate STEM education to meet the needs of students, science, and society in 2040 and beyondJoin a diverse group of innovators on November 12, 13, and 19, 2020 at the Symposium on Imagining the Future of Undergraduate STEM Education, hosted by the National Academies of Sciences, Engineering, and Medicine and funded by the National Science Foundation. This virtual event will bring together a broad range of stakeholders who do not often have opportunities for collaboration and exchange: faculty and administrators from the full spectrum of higher education institutions, employers of STEM graduates, policy makers, funders, companies focused on higher education innovation, and associations serving higher education and individual STEM disciplines. Ideas generated at the Symposium will be published and shared broadly after the event to drive innovation in postsecondary STEM education and shape funding priorities for the National Science Foundation and other organizations.
