在当前的教学改革中,无论你用什么教学法,对于数学教学来说,是离不开课本的.课本是教学的立足之本.因此,我们要想搞好教学就要在课本里大做文章,充分利用课本,引导学生从中得到尽量大的效益,既学到必要的知识,又获得应有的能力. 下面以重点中学高中代数课本第二册的两章为例谈谈个人体会. 在数列一章中,当讲到等差数列的通项公式时,教材从a_2=a_1+d,a_3=a_1+2d,a_4=a_1+3d……进行观察,归纳推理得到a_n- In the current teaching reform, no matter what teaching method you use, for mathematics teaching, it is inseparable from the textbook. The textbook is the basis of teaching. Therefore, if we want to do a good job in teaching, we must do it in the textbook. Article, make full use of textbooks to guide students to get as much as possible from the benefits, not only learn the necessary knowledge, but also get the necessary capabilities. The following two key chapter two of the key secondary school high school algebra textbooks as an example to talk about personal experience. In the chapter of the series, when we talk about the general term of arithmetic series, the textbook is observed from a_2=a_1+d, a_3=a_1+2d, a_4=a_1+3d..., and inductive reasoning gives a_n-
