Application of CBL Teaching Method in Clinical Microbiology Laboratory Training for Residents

Clinical microbiology laboratory training for residents has long faced the limitations of traditional Lecture-Based Learning (LBL), which is characterized by an overemphasis on technical operations, inadequate cultivation of clinical thinking, and a disconnection between testing and diagnosis, and treatment. In this study, a case-sharing teaching model based on Case-Based Learning (CBL) was introduced, and a hierarchical and progressive teaching framework was constructed. Using common clinical infection cases as a carrier, the study implemented case screening, data collection, analysis, and reporting, stepped problem discussion, and multidimensional evaluation feedback in stages. Teaching practice has shown that the CBL model significantly improves trainees’ clinical interpretation skills of test results, antimicrobial drug decision-making logic, and multispecialty collaboration awareness, while strengthening autonomous learning and evidence-based thinking skills.
