小学数学教学中的定义、性质、运算规律和数量关系等基础知识,大多是借助对具体实例的观察分析,通过抽象概括揭示出来的。教学时,应注重研究对于不同的结论,如何采用不同形式进行抽象概括。一、揭示式抽象概括法揭示式抽象概括,是指在学生对具体实例的观察比较的基础上,教师提供出结论框架,引导学生借框架提供的思路得出结论。如,学习“得数是11的加法”时,可引导学生进行如下具体操作(使用学具)和思路择优对比。
Elementary mathematics teaching in elementary definition, nature, operation law and quantity relations and other basic knowledge, mostly through the observation and analysis of specific examples, revealed through abstract summary. Teaching, should pay attention to research for different conclusions, how to use different forms of abstract summary. First, the disclosure of abstract summary method Reveal the abstract summary, refers to the students on the basis of observation and comparison of specific examples, teachers provide a conclusion framework to guide students to draw conclusions through the framework provided. For example, when learning “The Addendum is 11 Additions”, you can guide the students to conduct the following specific operations (using the learning tools) and compare their ideas.
