摘要：

科学的数据记录习惯是化学工作者必备的基础素质之一,而大学时期是培养这种习惯的关键阶段。本文从有效数字的重要性出发,针对学生不规范记录数据的现象及原因进行了讨论,提出调动学生的主观能动性使其真正认识到有效数字的重要性是教学改进的入手点,并就此提出相应的改进措施。

关键词: 有效数字, 数据记录, 主观能动性, 教学改进

Abstract:

It is one of essential capacities for chemists to record data scientifically, and college education is a pivotal period for students to develop the basic habit. In light of the fundamentality of significant figures, problems reflected in students' data recording and the cause are discussed. It is suggested that the key approach to solve these problems is to arouse the subjective initiative of the students to make them pay attention to the importance of significant figures. And suggestions for improvement are also proposed.

Key words: Significant figure, Data recording, Subjective initiative, Educational improvement
