1设计说明1.1学情分析本专题涉及的知识点主要有函数、统汁图表、方程、解直角三角形,涉及的数学思想方法主要有数形结合思想、用样本估计整体的思想、统计思想以及整体观察与局部分析相结合的阅读理解方法。若是用文字连续、完整地描述题目,例如直接给出点的坐标,利用待定系数法求函数解析式,又如直接给出一组数据,求平均数、中位数、众数、方差等,85%的学生都可
1 Design Description 1.1 The Analysis of Academic Situation The topics covered in this topic mainly include functions, unified juice charts, equations, and right-angled triangles. The mathematical methods involved mainly include the idea of combining figures with form, using the sample to estimate the overall thinking, statistical thinking and overall observation Reading comprehension combined with local analysis. If the text is continuous and complete description of the problem, for example, the coordinates of the point is given directly, the use of undetermined coefficient method to find the function analytic formula, or directly given a set of data, the average, median, mode, variance, 85% of students can be
