高三化学结构化教学实践路径——以“晶胞的计算专题”一课为例

The Practice of Structured Chemistry Teaching in Grade Three in Senior High Schools--A Case Study of“Cell Computing”

研究以高三化学课为例,探索结构化教学的实践路径。课前,教师要先进行结构化设计,并通过导学案帮助学生自主先学,再依据学生完成导学案的反馈,即以真实学情为出发点二次备课;课中,利用小组合作充分暴露学生的相异构想,在相异构想的辨析中深入挖掘知识本质,促进学生形成结构化认识,从而克服畏难情绪,突破难点专题;课后,针对性助学,促使每个学生都能建立相对稳定的结构,促进知识与方法的掌握和应用,全面提升学生的思维品质和学习能力。

Yinchuan San Shayuan Upstream School has implemented structured teaching since 2017.This study takes the grade three chemistry course of the senior high school as an example to explore the practical path of structured teaching.Before class,firstly,teachers should conduct structural design and help students to learn independently through the learning guide.Secondly,students should finish the feedback according to the learning guide,that is,the preparation of the second lesson starts from the real learning situation.In class,the alternative conceptions of students are fully exposed by group cooperation.The essence of knowledge is deeply explored in the discrimination of alternative conceptions,so as to promote students to develop a structured understanding and overcome the fear of difficulties and break through the difficult topics.After class,targeted education helps every student to establish a relatively stable structure,promotes the mastery and application of knowledge and methods,and comprehensively improves students’thinking quality and learning ability.
