摘要
化学键是高中化学教学中一个比较抽象而难理解的概念,加之,由于中学化学教学中的知识和概念的系统性不强,更使学生难以掌握化学键的概念。在多次"化学键"教学的实践中不断从教与学中总结,再次通过与学生交流,不同层次学生提出了不同的疑问,分析了问题的存在的根本原因,总结运用知识系统性在"化学键"进行教学,取得了好的教学效果。
The chemistry bond knowledge is a concept of the abstract and difficult understand on chemistry teaching in high school,Also,in high chemistry teaching the system of the knowledge and concept is not very well on chemistry.Above the students are difficult to student the concept of the chemistry bond.Base the many teaching and the exchanging with students,there are many questions which are put forwarded by students.I have analyzed the essence reason on these questions.There questions are surmounted with the knowledge＇s system on chemistry bond teaching.
