Objective To evaluate the role that problem based learning (PBL) teaching plays in the education of doctors. Methods A total of 240 7-year students who entered the China Medical University in Shenyang in 2004 were divided into two groups: one group used PBL teaching model while the second group used a traditional teaching model. There were 120 students in each group. At the end of the teaching, a questionnaire on PBL teaching model was distributed to the both groups. We organized and classified answers to the questionnaire and conducted statistical analyses. Results Problem based learning is a model for education in which students dominate the course, question the case, look for evidence, participate in the group discussion and reach resolution. This emphasizes the process of learning and the training of student abilities, instead of the teaching of knowledge only. PBL is more effective at meeting the requirements of the global minimum essential requirements in medical education (GMER). Conclusions PBL teaching plays an important role in the training of doctors
护理硕士生作为未来专业领域的中坚力量和领军人物，承担着教学、管理、临床实践指导等多重任务，其临床实践中的学习、深化和带教十分重要。而当前国内在对护理硕士生进行临床带教时，仍采用以科研为主的通才培养模式，缺乏针对性和个体化，也未充分体现护理学的应用性特点。以角色为基础的临床带教模式将护理硕士生的专业角色确定为护理教育者、管理者及高级临床实践者，强调以学生专业角色为导向，制定针对性的临床教学目标和计划，以培养具有专科特色的应用性护理人才。
ObjectivesTo compare the role of problem-based learning (PBL) combined with team-based learning (TBL) methods with traditional lecture-based learning in the clinical probation teaching of bone tumor and explore which teaching method is more suitable for clinical probation teaching of bone tumor.MethodsThe 60 students of the 2013 grade five-year program medical students in West China Clinical College of Sichuan University who were undergoing clinical probation teaching in the orthopedic bone tumor subspecialty of West China Hospital of Sichuan University in April 2017 were randomly divided into 2 groups. The trial group adopted PBL combined with TBL teaching method, the control group adopted traditional teaching method. The general situation of the two groups of students were compared. After the end of the probation, the two groups of students’ knowledge mastery, comprehensive ability and satisfaction were compared.ResultsThere was no significant difference in the gender composition and the assessment scores of the last semester diagnostics course of the two groups of students (P>0.05). After the probation, in terms of knowledge mastery, the trial group’s theoretical test scores (89.13±3.47 vs. 87.03±2.99; t=2.511, P=0.015), teacher evaluation (88.33±4.48 vs. 85.90±3.96; t=2.231, P=0.030) and student evaluation (89.83±2.97 vs. 87.47±2.91; t=3.117, P=0.003) were better than those of the control group. In terms of comprehensive ability, the trial group’s ability in reasoning and induction, information management, goal completion, and communication (17.90±1.09, 18.00±0.91, 18.00±1.02, 17.90±1.13) were better than those of the control group (17.20±1.13, 17.13±1.20, 17.10±1.24, 16.83±1.29), the differences were statistically significant (P<0.05). There was no statistically significant difference in satisfaction between the two groups of students (P>0.05).ConclusionsPBL combined with TBL methods can improve the effect of clinical probation of bone tumors, deepen mastery of professional knowledge, improve comprehensive ability, and improve teaching quality.
Objective To compare the effectiveness of three teaching modes, namely traditional teaching, online teaching, and online and offline blended teaching, in the teaching of the clinical nutrition elective course, and to evaluate the advantages of the online and offline blended teaching mode. Methods A total of 316 students taking the clinical nutrition elective course at Sichuan University in one of the three semesters, Fall 2019-2020, Spring 2019-2020, and Fall 2020-2021, were enrolled as the study population. In the offline group, 69 students used the traditional teaching mode; in the online group, 133 students used the online teaching mode through Chaoxing Xuexitong application; in the online and offline blended teaching group, 144 students used the traditional teaching mode combined with the online teaching. The final exam results and questionnaire satisfaction of the three groups were analyzed and compared. The exam results were presented as median (lower quartile, upper quartile). Results The exam results of the online group [males: 88.0 (85.0, 93.0); females: 91.0 (86.0, 94.0)] and the online and offline blended group [males: 90.0 (83.0, 94.0); females: 91.0 (87.5, 95.0)] were significantly higher than those of the offline group [males: 83.0 (77.0, 89.0); females: 77.5 (67.0, 87.0)] (P<0.001). Compared to the offline teaching mode and online teaching mode, the female students’ satisfaction with the online and offline teaching mode was better (P<0.01). Conclusion The online and offline blended teaching mode can significantly improve students’ performance and learning motivation, and provide a basis for promoting the reform of the clinical nutrition elective course.
Objective To explore the application effect of virtual reality simulation technology (VRST) combined with problem-based learning (PBL) mode in knee arthroscopy teaching in sports medicine department. Methods A total of 76 trainees in sports medicine at Sichuan Provincial Orthopedic Hospital from June 2021 to June 2022 were retrospectively selected. According to the different teaching modes, they were divided into the research group and the control group with 38 trainees in each group. The traditional teaching mode was implemented in the control group, while VRST and PBL mode were implemented in the research group. The objective assessment results and teaching effect feedback of the two groups were compared. Results There was no statistical difference between the two groups in the average theoretical score of the trainees (91.35±1.05 vs. 90.94±1.12, P>0.05). The scores of the three manipulating parts of the research group (9.03±0.24, 9.12±0.31, and 9.24±0.27, respectively) were higher than those of the control group (8.76±0.36, 8.44±0.57, and 8.35±0.51, respectively), moreover, trainees in the research group had higher scores for study enthusiasm, teaching satisfaction, three-dimensional space sense, and virtual reality conversion degree (9.12±0.16, 9.67±0.11, 9.34±0.22, and 9.56±0.18, respectively) than those of the control group (8.89±0.27, 9.16±0.34, 8.67±0.37, and 8.42±0.23, respectively), and the differences were all statistically significant (P<0.05). Conclusion VRST combined with PBL mode could improve trainees’ ability to operate arthroscopy significantly, and stimulate trainees’ subjective learning ability to improve teaching effect.
