强化“量”的概念,提高分析化学实验教学质量

Strengthen the Concept of "Quantity" and Improve the Teaching Quality of Analytical Chemistry Experiment

"量"的概念渗透在分析化学实验教学的每个环节,学生对其透彻理解对提高分析化学实验效果和培养学生严谨、细致、一丝不苟的工作态度具有重要意义。但分析实验教授过程中,发现学生存在实验态度不端正、基本操作不规范、实验环节详略不当、数据记录不正确等问题,这表明学生严重缺乏"量"的概念。针对上述情况,本文从"量"概念的培养角度出发,提出几点具体建议。

The concept of ＂quantity＂ penetrates in each link of analytical chemistry experiment teaching, and the well understanding of it is of great significance for the improvement of analytical chemistry experiment teaching and the cultivation of students＇s rigorous, careful, meticulous work attitude. Several problems had been found in the experiment process, such as not rigorous experimental attitude, not standard basic operation, the improper link, incorrect data record, which shows that students＇ lack of the concept of ＂quantity＂ According to the above situation, some specific suggestions were put forward from the perspective of the cultivation for the concept of ＂quantity＂ .
