贵州省兴义市高中课程改革进入第二年,高中化学选修3《物质结构与性质》涉及的内容都是师生普遍反映较难的一门选修模块。很多学校都按以往成熟的模式在高二下学期选了选修5《有机化学基础》,但其中仍有原子轨道杂化等涉及选修3的内容。本人认为,先学习选修3后学习选修5更有利于学生掌握高中化学的整体知识结构和培养良好的思维品质。选修3中原子结构与性质是学习结构化学的核心基础,探讨该部分教学并进行交流有利于同行促进课改。
Xingyi City, Guizhou Province, high school curriculum reform into the second year, high school chemistry elective 3 “material structure and nature of the” content are generally reflected more difficult teachers and students an elective module. Many schools chose elective 5 “Basic Organic Chemistry” in the second semester of their sophomore year according to the established pattern of maturity, but there are still topics such as atomic orbital hybridization that involve elective 3. In my opinion, learning Elective 5 after studying elective 3 is more conducive to students mastering the overall knowledge structure of high school chemistry and cultivating good thinking quality. Elective 3 atomic structure and nature of structural chemistry is the core of learning the foundation, to explore the part of the teaching and exchange is conducive to promoting curriculum reform counterparts.
