Exploring Full-cycle DeepSeek-assisted Case-based Learning in Undergraduate Radiology Education: A Respiratory System...

To evaluate the application of DeepSeek-assisted case-based learning (CBL) in respiratory radiology course across the full instructional cycle, including preparation, implementation, and evaluation.

This prospective, single-center study was conducted in 2025 and involved third-year medical undergraduates. CBL Preparation: Six cases were retrieved from the Hospital Information System (HIS), and six generated via DeepSeek-R1. Preparation times were recorded and compared. CBL Implementation: Students were assigned to either a DeepSeek-assisted group or a traditional CBL group, with discussion time recorded for each subgroup. CBL Evaluation: Teaching effectiveness was evaluated through test scores and questionnaires. Subsequently, DeepSeek-R1 provided personalized feedback to students based on their individual scores.

A total of 200 students (mean age 21.02 ± 0.89 years, 94 males) participated. DeepSeek-generated cases required significantly less time than HIS-retrieved cases (p = 0.016). During implementation, the DeepSeek group spent less discussion time than traditional group (p = 0.026). The DeepSeek-assisted group achieved greater test score improvements compared to the traditional group (p < 0.05). Questionnaire responses indicated higher self-directed learning, greater interest in radiology, improved learning efficiency, and lower perceived learning burden in the DeepSeek-assisted group (p < 0.05). Additionally, personalized feedback generated by DeepSeek was qualitatively reviewed by the radiology teaching department and considered educationally useful.

This study demonstrates that DeepSeek-assisted CBL effectively supports respiratory radiology education throughout the entire course process-preparation, implementation, and evaluation-by enhancing efficiency, boosting student interest and engagement, improving performance, and providing valuable post-class feedback.
