课程改革进入我区已整十年了,这十年的成长期给我们的课堂教学带来了可喜的变化:既看到了一个全新的、富有活力的数学课堂,也感受到了学生的聪明才智.但实践过程中也暴露出一些问题,遂撰文与同行共研.问题一重间接经验,轻直接经验.【案例一】“二元一次方程组(代入法)”教学片断师生首先共同完成下列填空练习,旨在强化用含一个未知数的代数式来表示另一个未知数这一变式训练,为例题教学做铺垫. Curriculum reform has been in my area for ten years. The ten-year growth period has brought a welcome change to our classroom teaching. We have not only seen a brand new and dynamic math class, but also felt the students’ ingenuity. However, some problems have also been exposed during the course of practice, and then the author and his collegiate work together. The problem one indirect experience, light direct experience. [Case I] “Binary Equations (Substitution) ” The following fill in the blank exercises, aimed at strengthening the use of algebraic unknowns to represent another variant of this variant training, paving the way for example teaching.
