摘　　要：为了提升大型仪器设备实验教学的效果,以气相色谱-质谱联用实验为例,将水样前处理过程、气相色谱条件优化过程和质谱数据后处理过程作为教学的重点,以增强学生的实验操作能力和对实验过程与结果的分析能力。结果表明,通过对教学模式的改革,教师与学生的互动得到加强,学生动手能力得到锻炼,对气相色谱-质谱联用原理的理解更加深刻,教学效果显著提高。Taking gas chromatography-mass spectrometry (GC-MS) experiment as an example,our course highlights the pre-treatment of water sample,the optimization of gas chromatographic condition and the post-processing of mass spectrometry data,thus enhancing students’ ability to perform their experiment and analyze the experimental process and results.It turns out that,the teaching effect has been improved significantly after the reform of teaching mode.Besides the enhanced interaction between teachers and students,students get more chances to practice and grasp the principle of GC-MS.
