摘要现代仪器分析实验教学中普遍存在着诸多方面问题如：学生多而大型仪器资源稀缺；学生无法理解仪器原理、构造及不了解其操作规程；实验课时少，学生不能充分了解、接触仪器；学生对实验不重视、兴趣低；实验内容和形式较传统，缺乏思考和创新等。本文通过电化学仪器分析实验视频教学方法的改革实践，即：不用老师讲解实验，自主参考实验讲义和观看实验视频后，进行实验。对于解决上述提到的问题取得了有效地进展，较传统教学方法更为有效地掌握了各仪器的分析方法，取得了较好的实验教学效果。47794

Abstract: There are many problems in current educational practice of instrumental analysis experiment such as: Large instruments of analysis are scarce while more and more students need them; Students can’t understand the principle structure and their procedures of those equipments; lesson period is few and students can’t fully understand and contact the instrument; students do not pay attention to the experiment and not interested in it ; the content and form of the experiments are too old, lack of thinking and innovation and so on. This article made an effective progress about how to solve the problems above. By practicing of video teaching methods of instrumental analysis experiment we can master the analysis of each instrument more effectively than traditional teaching methods. In video teaching mode, students should conduct experiments all by themselves after watching the experiment videos and referring the experiment handouts. Teacher do not explain the experiment in class any more.
