摘要:

从培养研究型人才的角度出发,阐述了研究性教学模式在基础化学实验教学过程中的必要性。以“硫代硫酸钠溶液标定实验”为教学案例,引导学生主动探索,综合运用所学理论知识和技能,选择碘酸钾作为基准物,从酸度、加水量、反应时间和碘化钾溶液加入量四个方面考查实验条件和终点判断方法。实验设计和教学过程的实施,有助于培养学生系统的研究方法、严谨的科学思维和勇于探索创新的科学素养。

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
