基于问题导向学习法的分析化学实验与理论知识融合的教学改革——以“水硬度的测定”为例

Teaching Reform of Analytical Chemistry Experiment and Theoretical Knowledge Integration Based on Problem-Based Learning:A Case Study of“Determination of Water Hardness”

分析化学实验是一门兼具理论性、实践性和应用性的课程,主要训练学生规范操作并培养学生运用分析化学理论知识解决实际问题的能力。目前普遍存在着分析化学实验课程教学与理论教学严重脱节的问题,学生习惯“照方抓药”。本文将问题导向学习法应用于分析化学实验教学,通过改进教学模式、完善课程内容和优化考核方式开展教学改革,促进实验与理论教学的有效融合,充分调动学生的学习自主性,培养学生观察、思考、分析和解决问题的能力,有效提高实验课的教学效果。

An analytical chemistry experimental course should include theoretical,practical,and applicable properties,which mainly trains students to standardize operations and cultivates their ability to apply theoretical knowledge of analytical chemistry to address practical problems.Currently,a serious disconnect between experimental and theoretical knowledge exists as students are used to“taking prescriptions as prescribed”.This study applies a problem-based learning method to the experimental teaching of analytical chemistry.To promote effective integration between experimental and theoretical teaching,teaching reform was performed by improving teaching mode,perfecting course content,and optimizing examination methods.This can completely mobilize students’learning autonomy and cultivate their abilities to observe,think,analyze,and solve problems.In this manner,the teaching effect of the experimental course was effectively improved.
