| 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. |
