在培养小学生归纳能力的实践中,我们发现:如果教学不得法,就很可能在培养学生归纳能力的同时,使学生形成思维定势,导致学生不能适应变化了的情况,很难找出新方法去解决新问题。下面就结合五年制数学教材(第七册)中“角的认识”一课的教学,谈谈怎样在教学中培养学生的归纳能力,防止思维定势的产生。 根据归纳推理的前提是否考察了某类事物的全部对象,可把归纳推理分为完全归纳推理和不完全归纳推理两种,小学数学中常用的是不完全归纳推理。不完全归纳推理又可分简单枚举归纳推理和科学归纳推理两种,本课在指导学生认识射线和角时,应注意培
In the practice of cultivating pupils' abilities of inducing, we found that if the teaching can not be law, it is very likely to develop students' thinking ability while cultivating the students' inductive ability, so that students can not adapt to the changed situation and find it hard to find out the new method To solve new problems. The following combination of five-year mathematics teaching materials (Volume VII) “angle of knowledge” a lesson about how to train students in the induction of how to prevent the generation of thinking. According to whether the premise of inductive reasoning examines the whole object of a certain kind of thing, inductive reasoning can be divided into totally inductive reasoning and incomplete inductive reasoning. Commonly used in elementary mathematics is incomplete inductive reasoning. Incomplete inductive reasoning can be divided into simple enumeration inductive reasoning and scientific inductive reasoning two, this lesson in guiding students to know the ray and angle, should pay attention to training
