Exploration and application of the PIL teaching model based on medical-engineering integration in aerospace cardiovascular medicine education under the “New Medicine” framework

AIM To explore the application of the PIL teaching model in aerospace cardiovascular medicine education, guided by the medical-engineering integration teaching conceptunder the “New Medicine” framework.

METHODS Taking the chapter “Effects of weightlessness on cardiovascular function and protective measures” as an example, 51 students majoring in Aerospace Medicine in 2021 were selected as the control group, and traditional teaching mode was adopted; 56 students from the 2022 class will serve as the experimental group and adopt the PIL teaching mode. After the course, theoretical and practical operation exams will be conducted, and the experimental group will additionally add a formative assessment section for innovative design project proposals. In addition, teaching effectiveness evaluation will be conducted in the form of anonymous survey questionnaires and scientific research achievement statistics.

RESULTS Statistical analysis revealed that, compared to the control group, the theoretical examination scores and total scores of the experimental group were significantly elevated (P<0.05), while no significant difference was observed in the practical operation examination scores between the two groups. The increase in the experimental group's total score was not solely attributed to the improvement in theoretical examination scores, but also to the bonus points earned from the innovative design project proposal. Additionally, the questionnaire results showed that, compared to the control group, the experimental group demonstrated significant improvements (P<0.01) in learning initiative, teamwork ability, and the capacity to expand innovative thinking in the integration of medicine and engineering. The statistical analysis of research outcomes showed that students in the experimental group had made improvements in both extracurricular research and skills.

CONCLUSION The PIL teaching model significantly enhanced educational outcomes in aerospace cardiovascular medicine, deepened students’ understanding of the intersection between medicine and engineering, and fostered the advancement of aerospace medicine education. This approach provides strong support for cultivatinginnovative aerospace medicine professionals.
