在高中阶段,算法是一个全新的课题,算法是数学及其应用的重要组成部分,已经成为计算科学的重要基础。算法思想是高中学生应具备的一种数学素养,牛顿迭代法求方程的近似解是高中信息技术和数学的一个重要知识点。Visual Basic是高中信息技术的教学内容,对学生学习算法有着重要的作用,通过牛顿迭代法的思想、原理、算法、流程图和Visual Basic程序代码,然后进行牛顿迭代法求方程的近似解算法的Visual Basic上机实践,让学生形成分析问题、解决问题的思路,培养学生的逻辑思维能力和创新思维能力。
In high school, algorithm is a new topic. Algorithm is an important part of mathematics and its application. It has become an important foundation of computational science. The idea of algorithm is a kind of mathematical accomplishment that high school students should have. Newton’s iterative method is an important knowledge point of information technology and mathematics in high school. Visual Basic is a high school information technology teaching content, which plays an important role in student learning algorithm. Through Newton iterative method’s thought, principle, algorithm, flow chart and Visual Basic program code, and then Newton iterative method to find the approximate solution of the equation Visual Basic on the machine to practice, so that students form the analysis of problems, ideas to solve the problem, develop students’ logical thinking ability and innovative thinking.
