类比推理在初中数学教学中运用比较广泛,掌握此数学技巧,能让学生从题海中解脱出来,提高数学思维能力,提高解题能力,使思维更活跃,更具有创新意识。类比推理就是根据两类事物或两个对象间存在着的相同或不同属性,推断另一类事物也可能具有某种属性的思维方法。在数学的教学过程中我们往往会遇到一些关于推理现象的问题,比如:分式的运算、分数的运算、全等三角形以及一元二次方程等等。
Analogical reasoning is widely used in junior high school mathematics teaching. Grasping this mathematical skill can help students to be freed from the sea of questions, enhance their mathematical thinking ability, improve their ability to solve problems, and make their thinking more active and innovative. Analogical reasoning is based on two types of things or the existence of the same or different attributes between two objects to infer that other things may also have some kind of attribute thinking method. In the teaching of mathematics we often encounter some problems on reasoning, such as fractional operation, fractional operation, congruent triangle and quadratic equation and so on.
