“翻转课堂”在微生物学实验“细菌鉴定中常用的生理生化反应”教学中的应用与体会

Application of flipped classroom in Microbiology Experiment teaching:a case study of bacterial identification based on physiological and biochemical tests

摘要:

微生物学实验是高等学校微生物学课程的重要组成部分。开展微生物学实验的目的不仅是对微生物学基本技能的传授、理论的验证与拓展，也是对高年级本科生走向毕业设计及进一步开展研究生科研工作的训练。为了训练学生的科研思维，在已掌握微生物基本操作与实验技术的基础上，将最后一个实验"细菌鉴定中常用的生理生化反应"设计为"翻转课堂"形式。学生通过课前查阅资料，课上讲解实验原理、预期实验结果、观察与修正实验结果、分析与讨论实验结果完成该实验。"翻转课堂"的教学形式活跃了课堂气氛，使学生们能够更好地查阅资料进行预习，结果分析及实验结论的修订训练了学生细致观察、深入分析和严谨结论的科学素养。

Abstract:

Microbiology Experiment is an important course of microbiology in institutions of higher education. This course aims to not only impart basic skills, verify and expand theories in microbiology, but also train senior undergraduates for graduation projects and further research work in their graduate education. To train the scientific research thinking of students who had mastered the basic experimental techniques of microbiology, we designed the class of bacterial identification based on physiological and biochemical tests in the form of a flipped classroom. The students were guided to review textbooks and papers before class and explain the experimental principles, expect experimental results, observe and correct the results, and analyze and discuss experimental results during class. The teaching form of flipped classroom enlivens the classroom atmosphere, enabling students to better access textbooks for preview before class. The analysis of experimental results and the revision of experimental conclusions have trained the scientific literacy of meticulous observation, scientific analysis, and rigorous conclusion drawing for the students.
