Before the end of the nursing internship, evaluation will be conducted through theoretical and operational assessments, teaching effectiveness evaluation forms, and survey questionnaires. Results The theoretical and operational exam scores of the two groups of nursing students were higher in the study group than in the control group, and the difference was statistically significant （P<0.05). The evaluation of teaching effectiveness by nursing students in this department showed that the research group was higher than the control group, and the difference was statistically significant （P<0.05).
