As part of the MICB 211 teaching team, Evelyn Sun helped develop Case by Case: A Foundations in Microbiology OER to support a shift toward a more interactive and research-driven learning experience. By integrating open-access case studies from primary literature, the course moves away from traditional lecture-based instruction to a flipped classroom model, where students engage with microbiology concepts, analyze real-world data, and participate in deeper in-class discussions.
