A biochemistry course is a fundamental but important subject in medical education in China. In recent years, the number of international medical students has increased. Curriculum reform in biochemistry teaching is needed because of the knowledge limitations of students, a close linkage of biochemical content with clinics, the shortcomings of lecture-centered teaching, and the requirements for early clinical practice training and competence. In this study, we analyzed a novel curriculum reform, "Hybrid-PBL," which combined problem-based learning (PBL) with biochemistry lectures and was implemented for biochemical teaching at Dalian Medical University (DMU) in China. The change in curriculum affected 189 international medical students. This study selected two PBL cases concerning the basic biochemical issues of carbohydrate metabolism and liver biochemistry for the analysis, and ten examples of learning issues for each case were reported by the international students. A questionnaire was utilized to evaluate students' perceptions of the Hybrid-PBL, and examination scores were analyzed to assess the curriculum reform in biochemistry teaching. A statistical analysis revealed that the Hybrid-PBL curriculum was well accepted by the international students as an effective supplement to lecture-centered teaching programs. The students obtained more abilities, higher examination scores, and an improved understanding of biomedical information from the Hybrid-PBL program than from conventional teaching methods. Our study was an innovative trial that applied a PBL curriculum to the specific discipline of biochemistry and may provide a potential and promising new teaching method that can be widely utilized. © 2017 by The International Union of Biochemistry and Molecular Biology, 45(4):336-342, 2017.
生物化学课程在中国医学教育中是一门基础但重要的学科。近年来,国际医学学生的数量有所增加。由于学生的知识局限、生化内容与临床的紧密联系、以讲座为中心的教学的缺点以及早期临床实践培训和能力的要求,生物化学教学需要进行课程改革。在本研究中,我们分析了一种新颖的课程改革“混合式PBL”,它将基于问题的学习(PBL)与生物化学讲座相结合,并在中国大连医科大学(DMU)用于生物化学教学。课程的改变影响了189名国际医学学生。本研究选取了两个关于碳水化合物代谢和肝脏生物化学基本生化问题的PBL案例进行分析,国际学生报告了每个案例的十个学习问题示例。使用问卷调查来评估学生对混合式PBL的看法,并分析考试成绩以评估生物化学教学中的课程改革。统计分析表明,混合式PBL课程作为以讲座为中心的教学计划的有效补充,被国际学生广泛接受。与传统教学方法相比,学生从混合式PBL课程中获得了更多能力、更高的考试成绩以及对生物医学信息的更好理解。我们的研究是一项创新性试验,将PBL课程应用于生物化学特定学科,可能提供一种可广泛应用的潜在且有前景的新教学方法。© 2017年国际生物化学与分子生物学联盟,45(4):336 - 342, 2017。
