摘　　要：对于刚刚步入实验室的本科生来说,养成良好的实验操作习惯、树立良好的科研态度、培养良好的科研思维至关重要。然而,敷衍“交差”、缺乏独立思考能力、实验操作不规范成为实验课上部分学生的常态。粗食盐提纯实验作为一个综合性较强的实验,涵盖了多个化学基本原理以及多种基本操作。此实验对于提升学生科研素养具有较强的教学示范性。笔者结合多年教学实践经验,就如何以问题导向的教学方式让学生知其然,知其所以然,培养学生独立思考能力,提高学生分析问题、解决问题的能力,如何避免敷衍“交差”,如何规范学生实验操作三方面提出了个人见解,并对学生在实验过程中出现的由于操作不当引发的各种问题进行了分析。For undergraduate students who have just entered the laboratory,it is crucial to develop good experimental operation habits,establish a good research attitude,and cultivate good research thinking.However,perfunctory work,lack of independent thinking ability,and non-standard experimental operations have become the norm among some students in experimental classes.As a comprehensive experiment,the crude salt purification experiment covers multiple basic chemical principles and basic operations.This experiment has strong teaching demonstration for improving students'scientific research literacy.Based on years of teaching practice experience,personal opinions were put forward on how to use a problem oriented teaching method to help students understand the nature and reasons behind it,cultivate their independent thinking ability,improve their ability to analyze and solve problems,avoid perfunctory work,and standardize their experimental operations.Additionally,various problems caused by improper operation during the experimental process were analyzed.
