Methods: 80 cases of nursing interns in our school were randomly selected for analysis and research from January 2023 to December 2023, 40 cases of traditional teaching methods were named as the reference group, and 40 cases of demonstration and error methods were named as the seminar group and in-depth analysis and evaluation of the teaching effect of the two groups after the implementation of different teaching modes were carried out. Results: The seminar group achieved remarkable results in terms of teaching effect, and the performance of the interns in this group was significantly better than that of the reference group in terms of medical key skills such as aseptic operation technique, intravenous infusion operation, intramuscular injection operation, and catheterization operation, P < 0.05, which is of research value. Conclusion: After the nursing interns received the teaching intervention of the demonstration of the error method, their experimental operation performance and hands-on ability were significantly improved, and at the same time effectively stimulated their interest in learning, which is worth using.展开更多

Methods: The authors designed student questionnaires to investigate study weariness in 128 nurs-ing vocational college students. Results: Of the 128 students, 58 were tired of study, accounting for 45. 3%; 40 students often had weariness, accounting for 31. 3%; and 71 students had moderate or severe weariness, accounting for 55. 5%. Seventy-five students played on their mobile phone when they were tired of studying. Conclusions: The study weariness of vocational college students is a common phenomenon that has been developing rapidly. There are many factors that cause study weariness of professional college students. The students believe that the traditional teaching method is the main reason for study weariness. Reform of the teaching mode in a Nursing Basic Technology course effectively solved the learning problems of vocational college students. Teaching experiments for reform may have marked effects, and they are worthy of promoting.展开更多
