①本范例演示通过图形匹配故事情境的数学应用;②涉及核心概念为函数图像、立体几何体、逻辑推理、几何特性及相关性分析;③构造中运用了Polygon(多边形)、LaTeX(公式编辑)、Vector(向量)、Segment(线段)、RemoveUndefined(移除未定义对象)、RotateText(文本旋转)等GeoGebra命令与对象;④适合高中阶段数学教学,用于提升学生函数图像识别、空间想象及逻辑分析能力。

GeoGebra 命令及参数

  1. Polygon({(-2, 217), (10.9, 217), (10.9, -20), (-2, -20)}) → viewBox
  2. LaTeX((((("\text{" * QUESTION) * "\\") * INSTRUCTIONS) * "}")) → TEXT
  3. Polygon({(-6.5, -25), (-6.5, 220), (-3, 220), (-3, -25)}) → road
  4. Vector((0, 0), (0, 220)) → yAxisVector
  5. Vector((0, 0), (11, 0)) → xAxisVector
  6. LaTeX("\text{Time (seconds)}") → xLabel
  7. Segment((-4.75, -25), (-4.75, 220)) → roadDivider
  8. LaTeX("\text{Source: Vehicles - Guzaliia Filimonova/iStock/Getty Images}") → copyright
  9. LaTeX(UnicodeToLetter[10003]) → cmark
  10. LaTeX(UnicodeToLetter[10007]) → xmark
  11. RemoveUndefined(Zip[If[A, B], A, {showGraphA, showGraphB, showGraphC, showGraphD}, B, {1, 2, 3, 4}]) → whoIsTrue
  12. LaTeX("\text{A}") → labelA
  13. LaTeX("\text{B}") → labelB
  14. LaTeX("\text{C}") → labelC
  15. LaTeX("\text{D}") → labelD
  16. LaTeX((("\text{Graph " * If[activeAnimation ≟ 1, "A", If[activeAnimation ≟ 2, "B", If[activeAnimation ≟ 3, "C", "D"]]]) * " matches\\the animation.}")) → feedback
  17. LaTeX("\text{Distance Vs. Time}") → title
  18. RotateText(LaTeX["\text{Distance From Start of Road (metres)}"], 90°) → yLabel
