有效教学是一个古老而又年轻的话题。随着新一轮课程改革的不断推进与深入,新课程理念已经得到了广大数学教育工作者的认同。然而,观察当前的数学课堂,“穿新鞋走老路”的现象,形式化的数学教学仍然存在。如把课堂当成了戏台,学生成了教师表演的道具。可以说,这样的课堂是“失效”的。那么,如何提高数学课堂的效率呢?我认为要让学生感到上过课以后有收获,不能只留下一些表面热闹的东西,要让教学落到实处。在推行新课改的今天,新课程理念就像一阵新 Effective teaching is an old and young topic. With the continuous reform and deepening of the new round of curriculum reform, the new curriculum concept has been approved by the majority of math education workers. However, observing the phenomenon of the current math class and “wearing old shoes and walking the old ways”, formal math teaching still exists. If the classroom as a stage, the students became props for teachers. It can be said that such a classroom is “invalid ”. So, how to improve the efficiency of mathematics classroom? I think let students feel after class have a harvest, can not just leave some lively things, let the teaching be implemented. In the new curriculum reform today, the new curriculum concept is like a new
