方案设计题是指通过阅读、观察、探究等方法,从题目提供的相关材料中发现有用的解题信息并综合运用所学知识加以分析、计算、比较和判断,有时需要学生通过阅读、观察、归纳、探索和比较等手段寻找解决实际问题的方法,得出最佳方案;有时还通过建立数学模型,把实际问题转化为数学问题,选择最优方案. The program design question means to find useful information of problem solving through reading, observation, inquiry and other methods and to analyze, calculate, compare and judge synthetically using the learned knowledge. Sometimes it is necessary for students to read, observe, Induction, exploration and comparison to find the solution to the actual problem and get the best solution. Sometimes, through the establishment of a mathematical model, the actual problem is transformed into a mathematical problem and the optimal solution is selected.
