中文摘要：

本文在论述元素化学是无机化学的主脉和加强元素化学教学是学科发展的需要的基础上,提出要克服大一化学中弱化元素化学教学现象,强调必须加强元素化学教学研究的观点。着重介绍了从以区划分内容加强元素通性讲解、注重化学原理对元素化学内容的指导及应用,以及强调元素和化合物在周期表中的规律性讲解三方面论述大一理科元素化学教学的改革和实践。

英文摘要：

Based on the discussion that elemental chemistry is the chief of inorganic chemistry and strengthening elemental chemistry teaching is the need of disciplinary development, the paper proposes to o- vercome the phenomenon of weakening elemental chemistry teaching in freshman chemistry, and highlights to strengthen the research on the teaching of elemental chemistry. Freshman science elemental chemistry is in- structed from the following three aspects： dividing content by areas to strengthen the explanation of elemental connectivity, emphasizing the instruction and application of chemical principle for the content of elemental chemistry, and highlighting the explanation of regularity of elements and compounds in periodic table. The pa- per focuses on discussing the reform and practice.
