1问题的提出在几何教学的实践过程中,常常出现以下一些现象:(1)学生在教师的讲解后,能够很快明白某个数学概念或解题思路,但是在独立解决问题的时候,又不知从何人手,不会解答;(2)学生会背诵数学概念,会套用公式解决某类数学问题,但是一旦对这些数学问题进行了变式,学生就不知所措了;(3)对自然语言、符号语言、图形语言之间的相互转换懵懵懂懂,不会作与文字题对应的几何图形,更不会用符号语言写
1 Problems raised In the practice of geometry teaching, some of the following phenomena often occur: (1) After the teacher explains the teacher, he can quickly understand a mathematical concept or problem-solving ideas, but when solving the problem independently, (2) Students will recite math concepts and apply formulas to solve certain math problems, but students will be overwhelmed if they make any changes to the math problems; (3) , Symbolic language, the conversion between the graphical language 懵 懵 understand, not with the text corresponding to the geometry, but will not write in a symbolic language
