《数学课程标准(实验稿)》中明确提出:“有效的数学学习活动不能单纯地依赖模仿与记忆,动手实践、自主探索与合作交流是学习数学的重要方式。”如何在课改新理念的指导下改变学生以被动接受为主的学习方式,实现学生学习方式的彻底转变呢?下面谈一下自己教学“圆的面积”的课堂实践与反思。[案例]我在教学“圆的面积”时,让学生分小组合作探究;怎样把不会计算面积的图形(圆)转化为会计算面积的图形(长方形、平行四边形、三
“Mathematical curriculum standard (experimental draft)” made it clear: “Effective mathematics learning activities can not simply rely on imitation and memory, hands-on practice, independent exploration and cooperation and exchange is an important way to learn mathematics.” How to change the concept of the new curriculum Under the guidance of the students to change the passive acceptance of the main learning methods to achieve a thorough change in student learning it? Here to talk about their own teaching “round area” of classroom practice and reflection. [Case] When I was teaching “the area of the circle”, I asked the students to work together as a group to explore how to convert the graph (circle) that does not calculate the area into the graph that calculated the area (rectangle, parallelogram,
