Objective To explore the application effect of virtual reality (VR) technology in low vision teaching for optometry students. Methods Undergraduate students majoring in optometry at West China School of Medicine of Sichuan University were selected as the research subjects. The students enrolled in 2020 adopted the traditional lecture-based learning (LBL) teaching mode (LBL teaching group), while the students enrolled in 2021 adopted the VR teaching mode (VR teaching group). Both groups of students studied the content of the same chapter on low vision, completed in-class tests after learning, and completed a questionnaire survey. Results There were 28 students in the VR teaching group and 30 students in the LBL teaching group. There was no statistically significant difference in age or gender composition between the two groups of students (P>0.05). The in-class test scores of students in the VR teaching group were higher than those in the LBL teaching group (86.43±6.10 vs. 78.10±7.69, P<0.05). Except for “subjective discomfort with this teaching mode”, the differences in other evaluation results between the two groups were statistically significant (P<0.05). VR teaching group students generally believed that applying VR technology to low vision teaching helped understand the visual experience and daily life status of low vision patients, improved learning efficiency and hands-on ability, reduced learning burden, and hoped to use this teaching mode routinely in other subject teaching. All students in the VR teaching group believed that this teaching mode was interesting, highly innovative, and enhanced teacher-student interaction.Conclusions Applying VR technology to low vision teaching can enable students to personally experience the impact of various diseases on patients’ visual function and daily life. This teaching method not only optimizes and improves teaching effectiveness, but also has a high acceptance rate among students, which is worth further promoting in future optometry teaching.
Objective To explore teaching effects of case-based learning (CBL) in abdominal physical examination in diagnostics. Methods Among 83 undergraduates in grade 2007 and in major of 8-year clinical medicine were randomly divided into two groups. Under the same conditions, 41 in the CBL group were taught with CBL method, while the other 42 in the control group were taught with traditional teaching method. Their scores in standard patient (SP) practice assessment of abdominal physical examination, examination of abnormal abdominal signs, ability to analyze and write medical records, and right answers to abdominal examination in final exam were compared. Meanwhile, questionnaire surveys were distributed to them after class. Results There was no significant difference between the two groups in the scores of SP practice assessment or medical record writing and analyzing, but the CBL group was obviously superior to the control group in the tests of abnormal abdominal signs and the right answers to abdominal examination in final exam (Plt;0.05). The questionnaire surveys revealed that the CBL group obviously scored higher in the following 3 items: increase the learning interest and commitment, strengthen the ability to analyze and solve problems, and improve the ability to combine theory and practice (Plt;0.05). Conclusion CBL method has an obvious advantage to improve the teaching quality in abdominal physical examination in diagnostics.
Objective To explore the effectiveness of situational experiential teaching mode in emergency internship teaching. Methods Interns from the Department of Emergency, Jiangyou Fifth People’s Hospital from July 2022 to May 2023 were selected as the research subjects. The interns were randomly divided into a trial group and a control group using a random number table method. The trial group adopted a situational experiential teaching mode, while the control group adopted a traditional teaching mode. Theoretical knowledge testing, clinical comprehensive ability assessment, and clinical information feedback were used to evaluate the effectiveness of different teaching methods. Results A total of 90 interns were included, with 45 people in each group, aged 18-23 years old. Both groups consist of 18 clinical medicine students and 27 clinical nursing students. There was no statistically significant difference in academic performance in school between the two groups of interns (P>0.05). The theoretical knowledge test score (92.98±2.71 vs. 85.29±6.24), clinical comprehensive ability assessment score (90.52±2.58 vs. 83.35±5.25) and clinical feedback (44 excellent and 1 fine in the trial group vs. 25 excellent, 5 fine, and 15 poor in the control group) of the trial group were better than those in the control group (P<0.05). Conclusions The situational experiential teaching mode can enhance interns’ learning interest, improve memory effectiveness, help students master theoretical knowledge, and enhance their comprehensive abilities in clinical evaluation and decision-making. It is worth promoting in clinical practice.
ObjectiveTo explore the feasibility of introducing student-standardized patients in the teaching reform of medical nursing course. MethodsWe chose four classes of nursing students from grade 2012 between September and December 2014 as the research subjects.Cluster sampling was used to choose two classes of 84 nursing students randomly as trial group, who received student-standardized patients in their practical learning; while the rest 2 classes of 83 students were chosen as control group, who received traditional teaching method.The course scores and the effect evaluation were compared between the two groups. ResultsThe basic knowledge test score of the trial group 31.28±4.81 was not significantly different from that of the control group 32.10±2.15(P > 0.05).The case analysis test score of the trial group 54.36±3.45 was significantly higher than that of the control group 43.12±1.37(P < 0.05).The communication ability, health education ability, skill operation ability and professional quality score of nursing students in the trial group were also significantly higher than those in the control group (P < 0.05).

The teaching process was full of livingness, and the teaching quality was improved.Conclusion The teaching model of PBL can break through the limitations of passive acceptance of book knowledge in traditional teaching model and improve the ability to handle the comprehensive clinical knowledge of liver cancer, which provides a new model to the teaching of liver cancer to graduate medical students in clinic.
Objective This study aimed to explore the characteristics and deficiencies of the current standardized training evaluation system for general practitioners (including professional master’s degrees), analyze the awareness and attitudes of teaching physicians toward entrustable professional activities (EPAs), and to explore feasible solutions for establishing an EPAs evaluation and assessment system for general practitioners in training. Methods This study used a questionnaire survey to investigate 158 clinical teaching professionals, analyzed the current status of the standardized training evaluation system for general practitioners, and explored the level of understanding and opinions of teaching physicians on EPAs. Results Currently, there were many assessments for trained general practitioner residents, but there were problems with excessive formalization, single assessment methods, and a focus on written assessments. The recognition rate of EPAs among preceptors before training was only 15.9%, which increased to 71.51% after training. The EPA system could improve understanding and facilitate rapid implementation in the short term (P<0.001). While recognizing the concept of EPAs, preceptors also suggested simplifying the EPA system. Conclusion To address the shortcomings of the current standardized training evaluation system for general practitioners, targeted work should be carried out to design EPAs for professional confidence behaviors. A concise and practical EPAs evaluation system should be established for general practitioners. In addition, teaching staff should be trained and educated on EPAs to improve their teaching competence and ensure the output of general medical education.
Objective To explore the application effect of 3D printed heart models in the training of young cardiac surgeons, and evaluate their application value in surgical simulation and skill improvement. MethodsEight young cardiac surgeons were selected form West China Hospital as the trainees. Before training, the Hands-On Surgical Training-Congenital Heart Surgery (HOST-CHS) operation scores of the 8 cardiac surgeons were obtained after operating on 2 pig heart models of ventricular septal defect (VSD). Subsequently, simulation training was conducted on a 3D printed peri-membrane VSD heart model for 6 weeks, once a week. After the training, all trainees completed 2 pig heart VSD repair surgeries. The improvement of doctors’ skills was evaluated through survey questionnaires, HOST-CHS scores, and operation time after training. ResultsBefore the training, the average HOST-CHS score of the 8 trainees was 52.2±6.3 points, and the average time for VSD repair was 54.7±7.1 min. During the 6-week simulation training using 3D printed models, the total score of HOST-CHS for the 8 trainees gradually increased (P<0.001), and the time required to complete VSD repair was shortened (P<0.001). The trainees had the most significant improvement in scores of surgical cognition and protective awareness. The survey results showed that trainees were generally very satisfied with the effectiveness of 3D model simulation training. Conclusion The 3D printed VSD model demonstrates significant application advantages in the training of young cardiac surgeons. By providing highly realistic anatomical structures, 3D models can effectively enhance surgeons’ surgical skills. It is suggested to further promote the application of 3D printing technology in medical education, providing strong support for cultivating high-quality cardiac surgeons.
