摘要:

分析化学(定量化学分析部分)是一门重要基础课,传统课程体系的特点可以概括为"记忆换运算"和"近似换简化"。大量公式不仅导致沉重的记忆负担,而且割裂了化学平衡理论的内在统一性,难以满足现阶段人才培养的要求。为了克服这些问题,提出分析化学"去公式化"新课程体系。新体系具有记忆负担轻、统一性强等优点,而且能够对化学平衡问题进行精确解析。从教研背景、体系特点、课程资源、考查考试和教学实践5个方面详细介绍新课程体系,为分析化学课程改革提供参考。

Abstract:

Analytical chemistry (the part of quantitative chemical analysis) is an important course in many universities. The traditional system of the course can be characterized by "calculation through memorization" and "simplification through approximation". A large number of formulae not only result in heavy burden of memorization, but also tear the uniformity of the theory of chemical equilibrium. In order to solve such problems, a new formula-free system is designed. The new system features low demand on memorization and high level of uniformity, and makes accurate calculations possible. The details of the new system are presented in five aspects including background, characteristics, resources, examination and practices.

Key words: Formula-free, Analytical chemistry, Course reforming
