| 摘 要： | 直观实验和几何证明是几何教学中常用的两种重要方法.学生对几何证明的本质还缺乏认识.学生认为直观实验不能算是几何证明,一方面因为直观实验存在误差,另一方面直观实验只能从不完全归纳中得出结论.

| Abstract: | Visual experiment and geometry proof were important in geometrical instruction.In the interview to 13 ninth grade students,the result that students could not understand the nature of proof was found,and students believed that visual experiment was not geometry proof.The reason was that visual experiment existed error,and the regulation was explored by incomplete induction. |
