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.
ObjectiveTo systematically review the efficacy of the application of team-based learning (TBL) pedagogy and traditional lecture-based learning (LBL) pedagogy in radiology education.MethodsPubMed, EMbase, Web of Science, WanFang Data, CNKI and VIP databases were electronically searched to collect randomized controlled trials (RCTs) of the application of TBL and LBL pedagogy in radiology education from inception to March 31st, 2020. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies; meta-analysis was then performed by using Stata/SE 16.0 software.ResultsA total of 11 RCTs involving 721 participants were included. The results of meta-analysis showed that TBL significantly improved students’ theoretical assessment scores (SMD=1.70, 95%CI 1.05 to 2.36, P<0.001), practical assessment scores (SMD=2.00, 95%CI 1.02 to 2.98, P<0.001), preference to the curriculum design (RR=1.53, 95%CI 1.19 to 1.97, P=0.001), agreed to more effective promotion in aspects of teamwork ability (RR=2.46, 95%CI 1.69 to 3.59, P<0.001), self-directed learning ability (RR=2.41, 95%CI 1.33 to 4.39, P=0.004), and clinical practice ability (RR=2.09, 95%CI 1.46 to 3.00, P<0.001) compared with LBL pedagogical method. However, no significant difference was found in the subjective evaluation of theoretical knowledge between two pedagogies.ConclusionsCurrent evidence shows that TBL pedagogy based on active learning and team cooperation has obvious advantages over traditional LBL mode in radiology education. Due to limited quality and quantity of the included studies, more high-quality studies are needed to verify above conclusions.
Objectives To train postgraduate medical students the ability of effectively using network resources and independently studying, and to explore new model of clinical liver cancer teaching. Methods The teaching model of problembased learning (PBL) to clinical liver cancer teaching was applied. Results The teaching model of PBL changed graduate student the status of passive acceptance to active participation. 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 To assess the affect of problem-based learning (PBL) versus literature based learning(LBL) in clinical medicine students. Methods Computer retrieval was conducted to search for controlled studies comparing PBL with LBL. The quality of included studies was critically evaluated and data was analyzed by using The Cochrane Collaboration’s RevMan 5.0 software. Results Finally 11 articles were included in the review, but most of them were of low quality.There are clinical heterogeneity between different studis which cause descriptive results. The PBL tended to be superior to LBL in the analysis-skill, self-directed learning skill, data-searching skill, and original skill.Conclusion PBL tends to be associated with better learning results among clinical medicine students compared withLBL methods. We need large-scale, randomized controlled trials of higher quality to confirm this.
Objective To assess the effect of problem-based learning (PBL) versus traditional methods in nursing students. Methods Computer retrieval was conducted to search for controlled studies comparing PBL and traditional methods. The quality of included studies was critically evaluated and data were analyzed by using The Cochrane Collaboration’s RevMan 5.0 software. Results A tota1 of 321 articles were retrieved, but only l1 were included. Metaanalyses showed that there was no significant difference between PBL and traditional methods in the objective knowledge of nursing students (SMD 0.12, 95%CI -0.32 to 0.56, P=0.6gt;0.05); but PBL was superior to traditional methods in the training of critical thinking (WMD 11.52, 95%CI 6.29 to 16.74), conflict resolution skills (WMD 8.09, 95%CI 5.02 to 11.16), clinical problem-solving skills (WMD 0.43, 95%CI 0.22 to 0.64), and communication skills (WMD 1.56, 95%CI 0.17 to 2.95). Although no significant difference was identified in the training of clinical decision-making skills, collaborative skills, and self-directed learning skills, PBL tended to be superior to traditional methods. Conclusion PBL tends are associated with better learning results among nursing students compared with traditional methods. However, most trials included in the review were of low quality, so large-scale randomized controlled trials of higher quality are needed to confirm this.
ObjectiveTo discuss the application of Miller pyramid teaching method in the competency training of new nurses in hemodialysis room and evaluate the effect.MethodsFourteen new nurses in hemodialysis room adopting conventional teaching method from January 2017 to December 2018 were retrospectively selected as the control group; from January to December 2019, another 14 new nurses in hemodialysis room were prospectively selected as the trial group and Miller pyramid teaching method was adopted. After three months of training, the theory and operation of the two groups of new nurses were assessed, and the post competency was assessed by using the Competency Inventory for Registered Nurse, and the teaching satisfaction was assessed by using the self-designed questionnaire on the teaching effect satisfaction of new nurses in hemodialysis room. The data of the two groups were compared.ResultsThe theoretical examination score (91.54±5.89 vs. 83.86±6.45), operational examination score (96.89±3.65 vs. 90.58±5.15), score of Competency Inventory for Registered Nurse (186.66±4.89 vs. 163.76±6.89), and teaching satisfaction (4.56±0.72 vs. 3.56±0.97) in the trial group were all higher than those in the control group, the differences were statistically significant (P<0.05).ConclusionMiller pyramid teaching method is feasible to train the post competency of new nurses in hemodialysis room, which is helpful to improve the theoretical basis, operational skills, post competency, and teaching satisfaction of new nurses in hemodialysis room.
Objective To explore the effects of lecture-based learning (LBL), problem-based learning (PBL) or combination of both on the cardiovascular system anatomy teaching. Methods Nine classes majoring in clinical medicine of Grade 2009 were randomly divided into the LBL class, the PBL class and the PBL combined with LBL class. The examination scores and questionnaire were used to evaluate the teaching effect. Results The students of LBL class did well in the objective questions test, but badly in case analysis. On the contrary, the students of PBL class did well in case analysis, but were weak in objective questions test. However, the students of PBL combined with LBL class could get good grades in both of them. Questionnaire showed that the PBL teaching method, PBL and LBL combined method could improve their communicative ability, learning motivation, comprehensive analysis ability, language skills and so on. Conclusion Combination of PBL and LBL not only enhances students’ memories about the anatomic knowledge, but also helps students practice efficiently what they learned to analyze clinical cases. Furthermore, the method of PBL combined with LBL improves, to a certain extent, students’ comprehensive quality.
