化学课程主要是以实验为基础的教学课程,而大多数的化学实验只是单纯地让学生熟悉每个实验的操作程序,并没有意识到让学生从中得到启发。如蒸馏实验,通过实际操作发现这项实验只是让学生学会如何简单地进行蒸馏操作(含沸点测定),却对实验的深层分析和表征方法缺少探究,这样容易造成一些实验误区,为此我们重新设计了实验内容,通过蒸馏分馏对比实验,从而培养学生独立分析解决问题的能力。
Chemistry courses are mainly based on experimental teaching courses, and most of the chemistry experiments simply to make students familiar with each experimental operating procedures, and did not realize that students are inspired. Such as distillation experiments, the actual operation of this experiment is only to allow students to learn how to simply distillation operation (including the boiling point determination), but the lack of exploration of the deep analysis and characterization methods of the experiment, so easy to cause some experimental errors, for which we re- The experimental content was designed to fractionate distillation experiments to develop students’ ability to independently analyze and solve problems.
