This $165,426 project grant award from the National Science Foundation's (NSF) Computer and Information Science and Engineering (CISE) program (CFDA 47.070) aims to transform online computer science theory education at the University of Chicago, University of Illinois, and Utah State University. The project seeks to develop interactive online exercises that provide more equitable and inclusive learning experiences, particularly for students historically underrepresented in computer science. Key objectives include creating innovative problem types with instant feedback, adaptive complexity, and culturally responsive contexts to improve student confidence, skills, and sense of belonging in theory-based computer science courses like algorithms and discrete mathematics. Through a multi-phase process of development, piloting, and evaluation, the project team will employ techniques like think-alouds, focus groups, and quasi-experimental studies to assess the impact of these novel online tools. If successful, this project has the potential to enhance career outcomes for underserved students and strengthen the overall computing workforce.
