所谓数学变式训练,即指在数学教学过程中对概念、性质、定理、公式以及问题从不同角度、不同层次、不同情形、不同背景做出有效的变化,使其条件或形式发生变化,而本质特征却不变。在数学的探究活动中,特殊化起着揭示信息的作用,特殊化的方法是从给定的区域内缩小范围,甚至缩小到一个特殊的值、特殊的点、特殊的图形等情况,再去考虑问题解答的合理性。而在得到猜想的过程中,让学生潜移默化地体会到了转化的数学思 The so-called mathematical variant training, that is, in the process of mathematics teaching concept, nature, theorems, formulas and problems from different angles, different levels, different situations and different backgrounds to make effective changes to change the conditions or form, and The essential characteristics are unchanged. Specialization plays a role in revealing information in mathematical inquiry activities. The specialization method is to narrow the range from a given area to even a specific value, a special point, a special figure, etc. Consider the rationale for problem solving. In the process of getting the guess, let the students subtly understand the conversion of mathematical thinking
