深化重点，解析难点，培养综合创新素质——细菌接合教学方法的探索

Cultivation of comprehensive innovation quality by deepening the key and difficult points——probing into the teaching method of bacterial conjugation

摘要:

接合是微生物学教学的重点和难点。为了让学生更直观地了解接合，我们除了系统介绍接合的发现过程及分子机理外，还开设了大肠杆菌与希瓦氏菌之间的远缘接合实验。理论教学采用以问题为导向的策略，在提问中培养学生思维的逻辑性，在讨论中传授科学的严谨性；实验教学采用以探究为主的方案，通过比较环境条件对接合的影响，培养学生耐心细致的实验作风。通过这种理论结合实验的教学方式，学生灵活发散的思维能力、不畏权威的质疑精神和宽广智慧的人文情怀得以培养，综合创新素质得以提高。

Abstract:

Conjugation is the key and difficult point in microbiology teaching. For student’s intuitive understanding of conjugation, we set up a conjugating experiment using Escherichia coli and Shewanella oneidensis, on the basis of systematic introduction of its discovery procedure and molecular mechanisms. A problem oriented strategy was adopted in theory teaching, thereby student’s logic thinking was developed in questions, and the scientific rigor was imparted in discussions. An inquiry based method was applied in lab teaching, where student’s meticulous operating style was nourished via exploring conjugation efficiency under different environmental conditions. By this way, student’s flexible thinking abilities, questioning spirits, and broad humanistic wisdoms were cultivated, and their comprehensive innovation qualities were improved.
