一、教学内容分析《重要有机物的相互转化》是高二化学选修《有机化学基础》专题4的最后一节内容,是高中有机化学极为重要的教学内容,将烃和烃的衍生物主干知识进行了串联,形成有机物转化关系图,引导学生建立有机化学的分类观和变化观,是促进学生认识发展,提高学科素养的重要内容。学生通过对必修和选修有机化学知识的学习,已经掌握了烃和烃的衍生物中多种类别的有机物,了解了大量相关的有机反应,此时学生的记忆会出现混乱与模糊。通过本节课
First, the teaching content analysis “Mutual transformation of important organic matter” is the last section of the second high school chemistry elective “foundation of organic chemistry” 4, is an extremely important teaching content of high school organic chemistry, the hydrocarbon and hydrocarbon derivatives of the main knowledge were In series, the formation of organic transformation diagram, guide students to establish the classification of organic chemistry and the concept of change is to promote students to recognize development, improve academic quality of the important content. Through the study of compulsory and elective organic chemistry, students have mastered many classes of organic matter in hydrocarbon and hydrocarbon derivatives and learned about a host of related organic reactions, at a time when students’ memories are confused and obscure. Through this lesson
