新的课堂标准实施以来,教材的开放性为每位教师提供了开发、创造的空间,教师更要从学生发展的角度开发教材,以促使学生思维的发展为核心,让课堂不断闪现智慧的火花。因此,教师在备课时,教学目标不是仅仅局限在一节课,而是站在单元乃至整套教材知识体系的角度研究一节课的重、难点,这样备课考虑了知识性目标,又促进了学生的思维。笔者以《图形的放大与缩小》为例来谈谈在课堂教学中如何关注学生发展,促进学生思维。 Since the implementation of the new classroom standards, the openness of teaching materials has provided each teacher with the space for development and creation.

Therefore, when teachers prepare lessons, the teaching goal is not limited to one lesson, but rather to study the heavy and difficult points of a lesson from the perspective of unit and even the entire textbook knowledge system. In this way, the lesson preparation takes into account the goals of knowledge and promotes students Thinking. The author of “graphics zoom in and out” as an example to talk about how to focus on classroom teaching student development, and promote student thinking.
