U-Behavior: A method to promote spaced and interleaved retrieval practice in challenging undergraduate microbiology and biomedical sciences courses

The underlying data for this study consist of anonymized student performance metrics, retrieval practice activity (RPA) usage logs (including timestamps of quiz attempts, scores, spacing intervals, and mixing patterns), UB-rubric scores, demographic descriptors (aggregated only), and exam/retention test scores from two undergraduate courses: Introduction to Biomedical Sciences (VMBS 100) and General Microbiology (MIP 300). These data were extracted from the university's learning management system (LMS) and course records. No raw individual-level data are shared due to privacy protections under institutional review board (IRB) guidelines and FERPA regulations; all analyses use de-identified, aggregated, or summarized forms.
