遵循一定的内容体系进行教学,可以使老师如庖丁解牛,游刃有余;可以使学生对所学知识系统化、网络化,加深对知识的理解和记忆,便于提取,能活学活用。我把新老教材进行对比并结合近十年的教学体会,从具体知识的承载对象:物质、化学反应、化学实验三个角度来阐述我对教材内容体系的一点感悟。 Follow a certain content system for teaching, you can make teachers such as Xiao Ding cattle, ease; can make the students systematization of knowledge, networking, deepen the understanding and memory of knowledge, easy to extract, to learn to use. I compared the new and old teaching materials and combined with the teaching experiences of the past ten years to expound my understanding of the teaching material content system from the perspectives of material objects, chemical reactions and chemical experiments.
