Abstract: Objective To explore the application effect of the O2O teaching and assessment mode based on the Feynman learning method in the CPR training for young nurses. Methods 80 nurses from the Nantong First People's Hospital between March 2019 and March 2022 were randomly selected as the subjects of this study. The nurses were divided into two groups using the random number table method. The control group implemented the routine teaching of CPR, while the experimental group implemented the O2O teaching and assessment model based on the Feynman learning method. After the teaching, the theoretical scores and operational scores of nurses in the two groups were compared by examination, and the differences in clinical competence, professional identity and learning satisfaction of nurses in the two groups were compared by questionnaire. Results After implementing the O2O teaching model based on the Feynman learning method, the theoretical scores of the nurses in the experimental group were significantly higher than those of the nurses in the control group, and the operational scores of the nurses in the experimental group were significantly higher than those of the nurses in the control group, with statistically significant differences (P<0.05). After the implementation of this teaching model, the clinical competence of the nurses in the experimental group was significantly higher than that of the nurses in the control group in the areas of critical thinking, clinical care, leadership, interpersonal relationship, legal ethical practice, professional development and educational consultation, with a statistically significant difference (P<0.05). After the implementation of this teaching model, the nurses in the experimental group had a significantly higher sense of professional identity than the control group in terms of sense of consistency, sense of control, sense of patient influence, sense of self-determination, sense of self-efficacy, sense of meaningfulness and sense of organisational influence, with a statistically significant difference (P<0.05). After implementing this teaching model, the nurses in the experimental group were significantly more satisfied with their learning than the control group, with a statistically significant difference (P<0.05). Conclusion The application of the Feynman Learning Method-based O2O teaching model assessment model in cardiopulmonary resuscitation training for young nurses to improve nurses' ability to master relevant knowledge and skills, enhance learning interest and professional identity, and increase nurses' satisfaction with the training.
