摘要
插补就是插入补充由起点到终点运行过程中一系列中间点的坐标以进行数据点密化,插补算法复杂,教学效果不佳。为提高教学效果,首先强调了插补的基本思想,分析了偏差计算规律,提出了终点判断的总步长法和两个终点计数器方法适用范围的不同和适用任意象限的插补计算流程。文中的教学方法有助于揭示知识背后隐藏的智慧可调动学生对插补问题的积极主动思考,提高了教学效果。
Interpolation is to insert and supplement the coordinates of a series of intermediate points in the process of running from the starting point to the end point to densify the data points,and the interpolation algorithm is complex and the teaching effect is not good.In order to improve the teaching effect,the basic idea of interpolation is emphasized,the deviation calculation law is analyzed.We propose the different suitable situations for two kinds of end point judgment,namely total step length and two end point counters,and finally optimize the interpolation computation process suitable to any quadrant.The teaching method of this paper helps to reveal the hidden wisdom behind the knowledge,mobilizes students'active thinking about interpolation problems,and improves the teaching effect.
