BACKGROUND
According to the updated concept of oral microbiology, the School of Stomatology, Wuhan University, has carried out oral microbiology teaching reforms during the last 5 years. There was no lab curriculum before 2009 except for a theory course of oral microbiology. The school has implemented an innovative curriculum with oral medicine characteristics to strengthen understanding of knowledge, cultivate students' scientific interest and develop their potential, to cultivate the comprehensive ability of students. This study was designed to evaluate the oral microbiology lab curriculum by analyzing student performance and perceptions regarding the curriculum from 2009 to 2013.
METHODS
The lab curriculum adopted modalities for cooperative learning. Students collected dental plaque from each other and isolated the cariogenic bacteria with selective medium plates. Then they purified the enrichment culture medium and identified the cariogenic strains by Gram stain and biochemical tests. Both quantitative and qualitative data for 5 years were analysed in this study. Part One of the current study assessed student performance in the lab from 2009 to 2013. Part Two used qualitative means to assess students' perceptions by an open questionnaire.
RESULTS
The 271 study students' grades on oral microbiology improved during the lab curriculum: "A" grades rose from 60.5 to 81.2 %, and "C" grades fell from 28.4 to 6.3 %. All students considered the lab curriculum to be interesting and helpful. Quantitative and qualitative data converge to suggest that the lab curriculum has strengthened students' grasp of important microbiology-related theory, cultivated their scientific interest, and developed their potential and comprehensive abilities.
CONCLUSION
Our student performance and perception data support the continued use of the innovative teaching system. As an extension and complement of the theory course, the oral microbiology lab curriculum appears to improve the quality of oral medicine education and help to cultivate high-quality innovative medical talents.
背景
根据口腔微生物学的最新理念，武汉大学口腔医学院在过去5年里开展了口腔微生物学教学改革。2009年以前除了一门口腔微生物学理论课程外没有实验课程。学院实施了具有口腔医学特色的创新课程，以加强对知识的理解，培养学生的科学兴趣，挖掘他们的潜力，培养学生的综合能力。本研究旨在通过分析2009年至2013年学生在课程中的表现和看法来评估口腔微生物学实验课程。
方法
实验课程采用合作学习模式。学生们互相采集牙菌斑，并用选择性培养基平板分离致龋菌。然后他们纯化富集培养基，并通过革兰氏染色和生化试验鉴定致龋菌株。本研究分析了5年的定量和定性数据。本研究的第一部分评估了2009年至2013年学生在实验室中的表现。第二部分采用定性方法，通过开放式问卷评估学生的看法。
结果
271名研究学生在实验课程期间口腔微生物学成绩有所提高：“A”等成绩从60.5%升至81.2%，“C”等成绩从28.4%降至6.3%。所有学生都认为实验课程有趣且有帮助。定量和定性数据都表明，实验课程加强了学生对重要微生物学相关理论的掌握，培养了他们的科学兴趣，挖掘了他们的潜力和综合能力。
结论
我们的学生表现和看法数据支持继续使用这种创新教学体系。作为理论课程的延伸和补充，口腔微生物学实验课程似乎提高了口腔医学教育质量，并有助于培养高素质的创新医学人才。
