二分法是数值计算中最简单常用的一种方法,课程标准1将它安排在模块1函数内容中.分析其目的主要有三点:一是学习一种求方程近似解的简单常用的方法;二是通过这个具体载体让学生体会到函数与方程间的联系.三是为后期算法的学习做一定的铺垫.如何在教学中较好地实现这三个教学目 The dichotomy is one of the simplest and most commonly used methods in numerical computation, which is organized into the functional content of module 1. The purpose of the analysis is mainly three-fold: one is to learn a simple and commonly used method of finding an approximate solution to an equation; Is through this specific carrier for students to understand the function and the relationship between the equation.Third, to do some paving the way for the study of the algorithm.How to achieve these three teaching objectives
