摘要仪器分析实验是一门具有传统的而又蓬勃发展的学科,仪器分析实验教学改革也必将随着学科的发展而不断深化。为了达到使仪器分析实验易于学生理解,在课堂教学中更好地发挥优势的目标,本文提出了视频化教学方法,通过拍摄实验视频,并将视频用于实验教学中。通过在课前自己观看实验视频和实验讲义后,独立动手完成实验,从药品的准备及配置、仪器的操作、软件的应用、数据的处理到视频的拍摄,不需要老师课前的讲解及操作示范。老师在整个实验过程中,只有在出现一些学生不能解决的和不懂的实验问题时才会给与帮助。44128
该仪器分析实验教学视频的使用,可以帮助学生更好地掌握仪器的操作方法,并且能够了解实验的整个过程,提高实验教学效率和教学质量。
Instrumental analysis experiment is a traditional and developing class.The reform of experiment teaching is bound to the development of science and the deepening of instrument analysis.
In order to make the instrument analysis experiment easy for students to understand,and have better advantage in the classroom teaching,a video teaching method was proposed in this paper by shooting videos of each instrument,then apply the videos in the experimental teaching.By watching these experimental videos and experimental materials before class,the students perform each step of experiments such as drug preparation,instrument operation,the application of the software and the data processing independently without teacher’s interpretation and demonstration.The teacher only need to help students when they are in trouble.
The instrument analysis experiment teaching video can help students to master the operation of instrument better,and improve the ability to understand the whole process of the experiment,thus improve the efficiency and quality of experimental teaching.
