新课程要求教师通过“分子和原子”帮助学生用微粒的观念去学习化学,但该课题生硬抽象,学生很难理解分子和原子真正的含义,一线教师每每上到这节课都犯难,因此,从课堂出发,就如何构建“分子原子”高效课堂进行了分析与探索。 The new curriculum requires teachers to help students learn chemistry with the concept of particles through “Molecules and Atoms”, but the subject is so abstracted that it is hard for students to understand the true meaning of molecules and atoms. Teachers often make it hard to come to this class, Therefore, starting from the classroom, this paper analyzes and explores how to construct an efficient classroom of “molecular atoms”.
