在小学数学教学过程中,教师应帮助学生从已有经验向学习经验跨越,最终实现经验的对接和提升,构建教师和学生、学生和思维的自然生态系统。然而,在实际教学中往往会出现学生经验与教学经验的割裂,导致教师的教学路径与学生经验不吻合,这种教与学的不对称,严重破坏了数学课堂的生态体系,不利于提高学生的数学能力。如何对接学生经验,实现和谐自然的课堂生态呢?笔者认为,教师要基于学生的原有经验和再生经验,从活动经验、生活经
In the process of primary mathematics teaching, teachers should help students to leap from existing experience to learning experience, finally realize the connection and improvement of experience, and construct the natural ecological system of teachers and students, students and thinking. However, in practical teaching, the separation of students’ experience and teaching experience often leads to the fact that the teaching path of teachers is not consistent with the students’ experience.

How to connect the students ’experience and realize the harmonious and natural classroom ecology? According to the author’s opinion, teachers should base on the students’ original experience and regeneration experience,
