变革课堂不是一触而就的,需要教师团队间的实践与研磨,更需要教师一种从内心出发的、为了学生高品质思维养成的努力探索。这中间有反复、有议论、可能还会有迷茫,但是基于课程标准、学生数学能力发展的课堂实践都是有意义的。变革课堂的方式有很多种,我们学校依据学生的知识特点和认知特点,惊醒有效的改进与整合,推行预习优化的目的就在于让教师再熟悉教材、把握重点和难点的基础上有意识地预设,让学生学得扎实、记得深刻、用得自如。 Change the classroom is not a one-touch, you need to practice and grind among the teacher team, but also from a teacher starting from the heart, in order to explore the efforts of students to develop high-quality thinking. There are repetitions, controversies, and confusion in the middle, but classroom practice based on the curriculum standards for students’ mathematical development makes sense. There are many ways to change the classroom. Our school, based on the students’ knowledge and cognitive features, awakened effective improvement and integration. The purpose of the pre-study optimization is to make teachers familiar with the teaching materials, grasp the key points and difficulties, and consciously pre- Let students learn solid, remember profound, use freely.
