Objective To systematically review the teaching effects of problem-based learning (PBL) combined with lecture-based learning (LBL) versus lecture-based learning (LBL) teaching models on students in surgical clinical education in China. Methods Such databases as The Cochrane Library, PubMed, CNKI, WanFang Data and VIP were electronically searched for randomized controlled trials (RCTs) on PBL+LBL versus LBL applied in surgery education in China from inception to February 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.2 software. Results Fourteen RCTs including 1 386 students were included. The results of meta-analysis showed, compared with LBL, PBL+LBL were superior in basic knowledge of surgery (MD=3.33, 95%CI 2.07 to 4.60, P<0.000 01), case analysis (MD=5.90, 95%CI 2.61 to 9.19,P=0.000 4), clinical skills (MD=3.38, 95%CI 0.57 to 6.19, P=0.02), comprehensive performance (MD=7.15, 95%CI 3.87 to 10.43, P<0.000 1) and teaching satisfaction (OR=3.05, 95%CI 1.90 to 4.9,P<0.000 01) with significant difference. There was no differences in inquiry/physical examination/medical record between the two groups (MD=0.82, 95%CI 0 to 1.64,P=0.05). Conclusions PBL+LBL teaching method is superior to LBL in surgical clinical education in China. Large-scale and high quality randomized controlled trials are needed to confirm the above conclusions.
Objective To diversify the methods of human physiology teaching for medical students at Chang Gung University College of Medicine. Methods We divided the grades of semester evaluation for physiology into two parts: 70% for lecture-examinations, 30% for non-examination-associated learning model including oral presentation of a scientific paper (conference), problem-based learning (PBL) performance, and quizzes. Results By a questionnaire survey at the end of the semester, we found that students were willing to spend time preparing non-examination-associated learning model; and from their own evaluations, the effectiveness of non-examination-associated learning was comparable to lecture-examination methods. Conclusion We conclude that from this analysis of students’ learning attitude and actual time (in hours per week) spent in each learning models, non-examination-associated learning model is well accepted and appeares to be as effective as traditional examination-forced study.
ObjectivesTo systematically review the application of evidence-based medicine (EBM) combined with problem-based learning (PBL) method in clinical teaching.MethodsDatabases including WanFang Data, CNKI, VIP, CBM, PubMed and EMbase were searched to identify eligible randomized controlled trials that compared EBM plus PBL with traditional lecture based learning (LBL) method in clinical teaching from inception to March 28th, 2020. Two reviewers independently screened literature, extracted data and assessed risk bias of included studies. Statistical analysis was performed using Stata 14.0 software.ResultsA total of 33 randomized controlled trials with 2 855 students were included. The results showed that students in EBM combined with PBL group obtained better scores of specialized theory (WMD=6.87, 95%CI 5.08 to 8.66, P<0.001), skills examination (WMD=10.57, 95%CI 8.98 to 12.16, P<0.001) and case analysis (WMD=9.79, 95%CI 4.71 to 14.88, P<0.001), comparing with those in LBL group. Besides, EBM combined with PBL method improved students’ overall ability including independent learning capability, clinical thinking ability, problem-solving capability, literature exploring capacity, communication and presentation skills and team-work ability.ConclusionsApplication of EBM combined with PBL method can improve clinical teaching quality.
ObjectiveTo explore the effectiveness of problem-based learning (PBL) during the internship process for undergraduates in general medical colleges and universities. MethodsFrom September 2011 to September 2012, PBL mode teaching was carried for the five-year undergraduates, in which students were encouraged to explore, innovate, and put forward questions by themselves, and teachers were responsible for guiding. Based on entrance theoretical examination results and the comprehensive evaluation results, the grade 2008 undergraduate interns who received "3+2" two-phase teaching were divided into experimental group and control group with 50 students in each. Students in the experimental group were given the PBL teaching method, while the control group continued to receive traditional teaching mode. Finally, we adopted questionnaire survey, theory exam, and skill evaluation to compare the two groups of students. ResultsFor the questionnaire survey, students in the experimental group got significantly higher marks in such items as "mutual assessment between teachers and students" and "skill operation knowledge mastery" than the control group (P<0.05), but in items like "medical ethics" and "social cultivation", the differences were not significant (P>0.05). For the theory exam results, the average score for students in the experimental group (84.98±9.78) was not significantly different from that in the control group (81.86±10.04) (P>0.05). For the skill operation, the average score for the experimental group was 8.87±0.89, which was significantly higher than that for the control group (6.80±1.46) (P<0.05). ConclusionPBL mode is worth popularizing for its function of improving students' practical operation ability and thinking ability. However, the improvement of theoretical knowledge learning needs to be further solved.
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
ObjectiveTo compare the effect of problem-based learning (PBL) and traditional teaching method (lecture-based learning) on clinical practical teaching of orthopedic surgery. MethodsBetween May 2012 and December 2013, 55 orthopedic interns were chosen to be divided into two groups: PBL group (n=29) and traditional lecture group (control group, n=26). Case report and examination on a completion of orthopedic surgery were used to assess the teaching outcomes. ResultsPerformance differences in content of presentation and capability of answers to questions were significant between PBL group and the traditional group in the report test (P<0.05). The test scores of case analysis examination in PBL group were significantly higher than those in the traditional lecture group (P<0.05). There was no significant difference between the two groups in other types of questions (P>0.05). ConclusionThe participants in PBL group have performed significantly better in culturing clinical thinking and comprehensive analysis, competence and in no circumstance did they perform worse than traditional lecture method.
The main approaches to medical education reform that have been introduced elsewhere in the world, including the integration of basic and clinical sciences into organ-based model, the establishment of a Center for Faculty Development and problem-based learning (PBL) have been introduced to the College of Medicine, Chung Shan Medical University (CSMU) since the mid 1990s. The process of developing the PBL approach can be divided into the following stages: Observation (1994-2000): In this stage, CSMU observed the practice and effectiveness of PBL programs in other domestic and foreign medical schools. At the same time, we assessed the possibility of introducing PBL to Chung Shan. When the authority decided to introduce PBL, a PBL committee was inaugurated. Preparation (2000-2002): In this stage, tutor training took place, as well as PBL case writing workshops to reach consensus among the faculty. To reduce the total amount of curricula and traditional teaching hours, we combined and simplified related curricula, so that one and half weekdays were reserved for PBL tutorials and students’ self-study. A preliminary course about how to learn well, including the philosophy and methodology of learning as well as evidence-based medicine (EBM), was integrated into premedical curricula. Practice (2002-2004): In light of the number of trained tutors and written cases that have been prepared, and the desire that the PBL would be successful from the start, CSMU chose to introduce PBL to the clinical curricula first in a hybrid curriculum design. This meant that the traditional teaching was retained at the beginning. Evaluation of PBL by the students was done at the end of each semester. Tutor meetings were held twice per semester. Advancement (2004-2006): In this stage, PBL was introduced to the basic medical curricula as well as to the premedical general curricula. Based on our experience and comprehensive evaluation, a PBL guidebook for tutors and students has been published and delivered to both groups. We also developed an on-line evaluation system containing the evaluation forms for students and tutors. Excellence (2006 onwards): In this stage, the PBL website and learning resources will be further developed, and we are designing the system for on-line PBL practice.In conclusion, the introduction to PBL for medical education is reasonable and feasible. It requires b administrative support, a long-standing and high commitment of the PBL committee, consensus among the faculty and an appropriate planning and evaluation mechanism.
Objective To systematically review the effects of problem-based learning (PBL) versus lecture-based learning (LBL) teaching models on students in surgery education in China. Methods Such databases as CNKI, WanFang Data and PubMed were electronically searched for literature on PBL versus LBL applied in surgery education in China up to June 30th, 2013. According to the inclusion and exclusion criteria, we screened literature, extracted data, and assessed the methodological quality of included studies. Then meta-analysis was performed using RevMan 5.2 software. Results Sixteen studies were included totally, all of which were low in quality. Compared with LBL, PBL was superior in surgery comprehensive scores (WMD=4.98, 95%CI 3.88 to 6.09, Plt;0.000 01), fundamental theoretical knowledge (WMD=3.09, 95%CI 0.81 to 5.38, P=0.008), clinical manipulation skills (WMD=4.70, 95%CI 2.69 to 6.71, Plt;0.000 01), and practical ability (WMD=2.13, 95%CI 1.11 to 3.15, Plt;0.000 1) with significant differences. Conclusion PBL teaching method is superior to LBL in surgery education.
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 study the effect of PBL teaching method which was applied in the clinical practice of diabetes nursing, and to analyze its advantages and shortages. Methods Seventy-seven undergraduates in major of nursing were randomly grouped into two: one as an experimental group was taught with PBL teaching method, while the other as a control group was taught with traditional teaching method. The questionnaire and final examination were adopted to analyze the teaching effect. Results The effect of PBL teaching method was better in the experimental group for stimulating learning motivation, helping students to closely combine the theory and practice, and promoting communication ability. However, there was no statistical difference in final examination between the two groups (Pgt;0.05). Conclusion PBL teaching method is much better than traditional teaching method in clinical nursing practice of internal medicine, for it can guide students to get the approaches for solving problems and cultivate their integrated diathesis and other abilities.
