一道“几倍多几”的测试题竟然错误百出,究其原因是笔者只关注教材的教学思路,却忽视了学生解题思路的拓宽。经过分析与补救,笔者突然顿悟:用教材教是数学教学的必然选择。其策略有:认识教材——备出高质量的课;活用教材——让课堂更有效;审视教材——让课堂更简洁。【缘起】接受“用教材教”的理念已经八年,笔者曾经围绕这个理念撰写过好几篇文章并相继在刊物上发表。但在一次 A “several times more ” test questions actually mistakes, the reason is that the author only concerned about the teaching of teaching ideas, but neglected the students to broaden their thinking train of thought. After analysis and remedy, the author suddenly epiphany: Teaching materials is the inevitable choice of mathematics teaching. Its strategy is: Recognize textbooks - prepare high quality lessons; use textbooks - make the classroom more effective; examine textbooks - make the class more concise. 【Origin】 Accepting “Teaching Textbooks” has been the subject of eight years. I wrote many articles around this concept and published them in journals one after another. But once
