引入“探究教学模式”培养学生的综合能力

Integrating “Explorative Teaching Mode”to Train Students Integrated Ability

为了培养学生的科研意识和综合能力,在经典的基础有机化学实验——乙酸乙酯的合成中引入"探究教学模式"。在合成实验基础之上增加了粗产品纯化过程在线跟踪、产品中乙酸乙酯纯度分析、杂质种类与含量分析以及乙酸乙酯结构表征的实验教学内容,分别采取气相色谱和便携式微型核磁共振波谱仪(45 MHz)进行分析,并比较了产品经气相色谱氢火焰离子化检测器FID和热导检测器TCD分析结果的差异。这种探究教学模式,不仅训练了学生基本操作技能,同时培养了学生的多角度思考问题的能力。

The ＂Explorative Teaching＂mode is integrated into the experiment of synthesis of ethyl acetate,in order to develop students awareness of scientific research and integrated ability. On the basis of synthesis experiment,the NMR（ 45 MHz） is introduced into this experiment,to teach students to track the purification of crude product,and identify the structure of ethyl acetate; the gas chromatography is introduced to analysis ethyl acetate existing in product and the type and content of impurities,and to compare the analysis results between flame ionization detector（ FID） and thermal conductivity detector（ TCD） analysis. This explorative teaching mode trains not only the students＇ basic operation skills,but also the students＇ ability to think from many angles.
