34、映出学生掌握知识的程度，同时也体现了学生学习的主体性.最后列举几个例子，与学生一起完成.教学中一方面教师要示范严格的书写格式，另一方面也可使学生顺着教师的思路，体验一下老师是如何想的，如何来考虑问题的，然后由学生完成当堂课的练习，也可让一两位同学上黑板完成.要了解学生是否真正掌握本节课的内容，可由学生自己进行课堂小结，接着布置作业进一步巩固本课所学知识.专家点评文档编码:CR8X6L2W2V2 HK2Z2O9M7T10 ZQ2Q7W1E6H6文档编码:CR8X6L2W2V2 HK2Z2O9M7T10 ZQ2Q7W1E6H6文档编码:CR8X6L2W2V2 HK2Z2O9M7T10 ZQ2Q7W
