一、问题的提出元素化合物知识是构成中学化学知识的基础和骨架。化学基本概念和基础理论的导出,是我们在对元素化合物知识感知、认识的基础上进行的;化学基本概念和基础理论的发展,又要依赖于对元素化合物知识的扩展和深入。同时,化学实验是对元素化合物知识生动的再现和认识,化学计算是对元素化合物知识的定量研究,化学用语是对元素化合物知识的记载和描述,所以离开了对元素化合物知识的学习和研究,其他化学知识将成为无源之水。在中学化学教学中,元素化合物知识贯穿了整个中学化学教材的始末。长期以来,学生普遍反映化学知识特别是元素化合物部分,内容繁、头绪多、易懂、
First, the issue of the proposed elements Compound knowledge is the basis and skeleton of chemical knowledge in secondary schools. The basic concepts of chemistry and the derivation of basic theories are based on our knowledge and understanding of the knowledge of elemental compounds. The development of basic concepts and basic theories of chemistry depends on the extension and deepening of the knowledge of elemental compounds. At the same time, chemical experiments are the vivid representation and understanding of the knowledge of the elemental compounds. The chemical calculation is a quantitative study of the knowledge of the elemental compounds. The chemical terms are the description and description of the knowledge of the elemental compounds, and thus leave the study and study of the knowledge of the elemental compounds, Other chemical knowledge will become passive water. In chemistry teaching in middle school, the knowledge of elemental compounds runs through the entire middle school chemistry textbook. For a long time, students generally reflect the chemical knowledge, especially the part of the chemical compounds, the content of complex, clues, easy to understand,
