Objective To investigate the effect of problem-based learning (PBL) used in the course of evidencebasedmedicine.Methods Totally eight classes were randomly assigned to the lecture based learning (LBL) group(n=4) and PBL group (n=4). The examination scores, questionnaire, and seminars were used to evaluate the teaching effectiveness. SPSS 11.5 software was used for statistical analysis. Results More than 50% of students in each group believed that the teaching method of PBL could activate learning enthusiasm and interest, improve problem analysis and independent study abilities. There were significant differences between the two groups in terms of comprehensive analysis, learning efficiency, digesting the contents of study and strengthening the teacher-student communication, and whether or not to perform PBL teaching. Apart from single choice questions, other types of examination questions and total scores have significant differences. Conclusions The PBL teaching model can effectively train undergraduateclinical thinking, cultivate the abilities of deconstructing problem, comprehensive analysis, literature retrieval, language expression, exploration innovation; and overall improve the teaching quality of evidence based medicine.
ObjectivesTo assess the effectiveness of BOPPPS method in teaching of evidence-based medicine for undergraduates.MethodsTwo classes from the first and second clinical medical college of Lanzhou University were randomly selected as BOPPPS group and traditional teaching group, respectively. The examination scores and questionnaire were used in combination to evaluate the teaching effectiveness. EpiData 3.1 software was used for data entry. SPSS 23.0 software was used for statistical analysis.ResultsA total of 25 students were in BOPPPS group and 26 in traditional teaching group. Baseline characteristics such as gender, age, participation in scientific researches, publication of articles were balanced between two groups. The score of the BOPPPS group was higher than that of the traditional teaching group, and there was a significant difference between two groups in evidence searching, evidence evaluation and total score (P<0.05). Compared with traditional teaching group, more students from BOPPPS group deem that study interest, learning initiative, problem analysis and solving capability, self-study capability, communication between teachers and students, information acquisition capability, information analysis and utilization capability, speech capability and so on are improved, and there was a significant difference between the two groups (P<0.05).ConclusionsThe BOPPPS teaching mode is beneficial for undergraduates to improve innovative and practical capability, and improve quality and effectiveness of evidence-based medicine teaching.
