“培养学生初步的逻辑思维能力”是九年义务教育小学数学教学大纲规定的教学任务和教育目标。而指导学生学习和掌握常用的逻辑思维方法,是培养和提高学生的逻辑思维能力,使学生乐于思考并善于思考的关键。在小学数学教学中要启发学生掌握如下一些常用的逻辑思维方法。一、分析与综合的方法。所谓分析的方法,就是把研究的对象分解成它的各个组成部分,然后分别研究每一个组成部分,从而获得对研究对象的本质认识的思维方法。综合的方法是 “Cultivating Students’ Initial Logical Thinking Ability ” is the teaching task and education goal stipulated in the mathematics syllabus for nine-year compulsory education primary school. To guide students to learn and master the commonly used methods of logical thinking is the key to cultivate and improve students’ logical thinking ability and make students willing to think and think well. In primary school mathematics teaching to inspire students to master some of the commonly used methods of logical thinking. First, analysis and synthesis of methods. The so-called analysis of the method is to study the object into its various components, and then study each component separately, so as to obtain the essence of the research object of thinking. The integrated approach is
