《普通高中化学课程标准》指出,化学是在原子、分子水平上研究物质的组成结构、性质及其应用的一门基础科学。而且,学生普遍认为高中化学元素化合物知识零碎,容易学,但容易忘,很难掌握牢固,上课时很轻松就听懂了,但课后用化学知识解决实际的问题时往往就束手无策。这些都是学生没有将高中化学的理论和概念灵活运用起来,对知识点之间没有有机的联系,没有形成整体的化学知识结构。为了改变这样的教学状况,我们重新审视了高 The “Standard Chemistry Curriculum for General Senior High School” states that chemistry is a basic science that studies the composition and properties of matter and its applications at the atomic and molecular levels. Moreover, students generally agree that high school chemical compounds are fragmentary, easy to learn, yet easy to forget, hard to grasp and easy to understand in class, but often do not know what to do when using chemical knowledge to solve practical problems after class. These are students who have not used the theories and concepts of high school chemistry flexibly, have no organic connection to knowledge points, and have not formed the overall chemical knowledge structure. In order to change such a teaching situation, we re-examine the high
