摘　　要：学生在学习分析化学弱酸弱碱溶液pH值的计算时常常捋不清头绪,巧借计算机编程学习思维将一元弱酸氢离子浓度计算式的推导过程绘制成程序框图,可有效地帮助学生理解不同简化式的适用条件。进一步的将一元弱酸溶液氢离子浓度计算式的推导过程进行Python编程演示,可加强学生对推导过程的逻辑印象,有助于学生对该知识点的理解与掌握,并可通过课外探索练习的方式激发学生的编程学习兴趣。本文所提出的教学方法可为非计算机类专业的信息化融合教学提供借鉴。Students are often confused when they are learning to calculate the pH value of weak acid and weak base solutions in analytical chemistry.By drawing a program chart like someone learn to program,students can easily understand the derivation process of the simplified calculation formula and its operating conditions.The derivation process had been demonstrated by Python programming,which can effectively strengthen students'logical impression,and help them master the knowledge.Furthermore,it also can further stimulate students'interest in programming learning through extracurricular exploration and exercises.The teaching method proposed in this article can provide reference for the non-computer professional information teaching.
