A CS Prof.-led proposal has been selected to receive a California Education Learning Lab award of up to $650,000. The proposal, “A’s-for-All (A4A): Scaling Mastery Learning Through Technology, Advocacy, Policy, and Partnerships” was led by CS Profs. Armando Fox and Dan Garcia in partnership with California State University, Long Beach, and El Camino College. The grant is designed to scale successful Learning Lab projects, expanding the positive impacts of STEM in public higher education. A4A proposes to build upon an open-source technology platform from UIUC to reorient formative and summative assessment toward mastery learning, ultimately providing students every opportunity to learn and demonstrate proficiency in various areas of introductory computer science courses. The scaling proposal will develop concept mapping tools so that faculty and students can track progress in student learning, and implement automated approaches to provide more flexibility for the ways in which students are able to demonstrate proficiency/mastery of the course.
