Abstract:

From the point of cultivating research talents, the necessity of research teaching mode in the teaching process of basic chemistry experiment is expounded. Taking "sodium thiosulfate solution calibration experiment" as the teaching case, students were guided to actively explore, and comprehensively use the theoretical knowledge and technology. Selecting KIO3 as the basis material, the experimental conditions and end-point judgment methods were investigated from four aspects: acidity, water addition, reaction time and KI solution addition. The design and practice of research-oriented teaching in the process of basic chemistry experiment teaching is helpful to cultivate students' systematic research methods, rigorous scientific thinking, and the scientific literacy to explore and innovate.

Key words: Research-type talents, Basic chemistry experiment, Research-based teaching, Innovative ability
