《普通高中数学课程标准(实验)》明确提出了用“二分法”求函数零点的要求.在新“课标”教材中,也增添了“用二分法求函数零点或方程近似解”的内容.随着计算机技术的广泛应用以及我国经济建设的迅猛发展,增添这部分内容既足必要的又足可行的.《中学数学教学参考》2008年第1～2、4期上刊登了几篇关于“二分法求函数零点近似值”的文章,其中谈到了教学中的具体尝试、感悟、经验以及困惑,甚至出现了这样那样一些与二分法的本质不太相符的认识和做法,笔者认为这些都是很正常的.事实上,正冈为有了这样或那样的认识,才给我们提供了研究的素材,毕竟理不辩不明嘛!从历史上看,在我国古代浩如烟海的经典中,中
“Ordinary high school mathematics curriculum standard (experiment)” clearly put forward the requirement of “dichotomous ” to seek function zero. In the new “course ” textbook, also added “using a dichotomy to find the function zero or equation The content of approximate solution. With the wide application of computer technology and the rapid development of China’s economic construction, adding this part of the content is both necessary and feasible. ”High School Mathematics Teaching Reference“ 2008, the first phase of the second period There have been several articles on ”dichotomizing the function zero approximation". It talks about the specific attempts, feelings, experiences, and puzzles in teaching, and even some such understandings that are inconsistent with the nature of the dichotomy. And the practice, the author believes that these are all normal. In fact, Masaoka has provided us with the knowledge of one kind or another, and it has provided us with material for research. After all, it is indisputable! From a historical perspective, in ancient China, In a vast array of classics, Chinese
