一、问题的提出在高中有机化学教学工作中,笔者觉得有两个问题困扰着教学:一是学生课前缺乏预习,课上有机化学新知识接受较慢,学生对有机物空间结构的复杂性、多变性等理解不透,有机物种类繁多,有机反应类型也完全不同于无机反应,学生感觉陌生,有机知识点学习花费较多时间,减少了课堂练习的时间,学生对有机化学的理解和综合运用方面达不到理想的效果,课堂效率不 First, the problem raised In the teaching of organic chemistry in high school, I think there are two problems plagued teaching: First, the lack of pre-class preview class, class new knowledge of organic chemistry to accept slower, students of organic matter spatial structure complexity, Variability and other indecipherable, a wide range of organic matter, the type of organic reaction is completely different from the inorganic reaction, students feel strange, organic knowledge point to learn to spend more time and reduce the time of class practice, students understand and comprehensive use of organic chemistry Do not achieve the desired effect, the classroom efficiency is not
