这个互动式自我评估演示了解简单不等式的过程。涉及的核心数学概念是不等式和代数。构造要点使用了 GeoGebra 命令如 If, Random, RandomElement, Textfield, Segment, Sequence；对象包括 useranswerineq, useransval, usergreaterthan, userincludepoint, userIneqIndexNum, a, SelectedIneqListIndexNum, ansvaldenom, ansvalnum, answervalue, P_{arrowright}, Inequality, textInstruction1, A, text2, text4, b, text3, textAnswerTitle, B, C, pic1, D, xLeft, xRight, yBottom, yTop, c, xAxis_{continuation}, ticksize, ListxaxisNumbers, numline, listTicks, U_1, d, listgreaterthanorequalto, listlessthanorequalto, listgreaterthan, listlessthann, typeinequalitylist。适合初中及以上学生使用，用于练习和自我评估。

GeoGebra 命令及参数

  1. If(userincludepoint, If[usergreaterthan, 4, 3], If[usergreaterthan, 2, 1]) → userIneqIndexNum
  2. Random(1, 4) → SelectedIneqListIndexNum
  3. RandomElement({1, 2, 1, 3, 1, 5, 1}) → ansvaldenom
  4. Random(-5, 7) → ansvalnum
  5. Textfield(a) → Inequality
  6. Segment((x(P_{arrowright}), -0.5), (x(Corner[2]), -0.5)) → xAxis_{continuation}
  7. Sequence(Text[i, (i - ticksize / 5, -3)], i, xLeft + 1, xRight - 1, ticksize) → ListxaxisNumbers
  8. Sequence((i, -0.6), i, xLeft, xRight, 1) → listTicks
  9. If(SelectedIndex[typeinequalitylist] ≟ 1 ∨ SelectedIndex[typeinequalitylist] ≟ 3, true, false) → arrowleft
  10. If(SelectedIndex[typeinequalitylist] ≟ 2 ∨ SelectedIndex[typeinequalitylist] ≟ 4, true, false) → arrowright
  11. If(useransval ≟ answervalue ∧ userIneqIndexNum ≟ SelectedIneqListIndexNum, true, false) → answercorrect
  12. RandomElement({-3, -2, -1, 2, 3, 4, 5}) → factora
  13. Textfield(useranswerineq) → InputBox1
  14. If(factora < 0, If[SelectedIneqListIndexNum < 2, 2, If[SelectedIneqListIndexNum > 3, 3, If[SelectedIneqListIndexNum < 3, 1, 4]]], SelectedIneqListIndexNum) → DisplayIneqListIndexNum

AI 绘图提示语参考

画一个交互式不等式求解练习图，包含坐标轴和不等式符号，根据用户输入显示正确答案，用不同颜色区分不等式类型，左侧和右侧分别有箭头指示方向，上方有数字刻度，中间有输入框和文本显示不等式和解的状态。
以上提示语为根据原始绘图命令整理而来，仅供参考。
