四边形的起始课,内容不多.几个概念,两个定理,如是而已.陆老师的这一课,却上得如此生动绚丽.是因为:他对新课程标准的理念有了较好的认识与理解.他努力地让学生在“做中学”;并反复地琢磨了本课可以渗透哪些数学思想方法。以及怎样渗透。又通过什么来渗透. 他找到了合适的“做中学”的载体——在本课.就是“拼地板”“绕圈子”这两项活动.有了好载体,学生既学得有兴趣.“做中学”也顺利地展开了. 由此可见.先进的新理念的信仰与指导.合适的活动载体的设计与发现,也是课堂教学成功的重大要素.
The starting point of the quadrangle is not much. There are several concepts, two theorems, and it is just that. Teacher Lu’s lesson is so vivid and beautiful because he has a better idea of the new curriculum standards. Understanding and understanding. He worked hard to make students “learn from doing”; and repeatedly pondered what mathematics ideas can be penetrated in this lesson. And how to penetrate. What did he infiltrate? He found the right carrier for “doing high school”—in this lesson, the two activities “flooring” and “circling around.” With good carriers, students are both interested in learning. “Secondary school” has also been successfully launched. This shows that the belief and guidance of advanced new concepts. The design and discovery of appropriate activity carriers is also a major factor in the success of classroom teaching.
