两类对象具有某些类似特征,由其中一类对象的某些已知特征推出另一类对象也具有这些特征的推理称为类比推理.类比推理是一种由特殊到特殊的推理,不仅是数学中一种非常重要的数学思想,而且在实际生活中也应用广泛.可是由类比推理得出的结论未必是真的,一定要经过严格的证明.1教学探究1.1问题的提出在进行人教A版选修2-2《类比推理》教学的一堂习题课中,有这样一道
Two kinds of objects have some similar features, some of the known features of one of them introduce another kind of objects and the reasoning that has these features is called analogical inference. Analogy is a kind of special-to-special reasoning, not only Mathematics is a very important mathematical thought, but also widely used in real life.However, the conclusions drawn by analogical reasoning may not be true, we must undergo a rigorous proof.1 Teaching Research 1.1 The problem is raised in the teaching of people A version of elective 2-2 “analogical reasoning” teaching an exercise class, there is such a
