新课的导入在整个教学过程中起着承上启下的作用。设计数学教学的新课导入,激发学生的学习兴趣已经成为我们数学教师迫切需要研究的问题。1.直接导入法。上课时教师直接说出本节课所要讲授的课题。这种导入方法适用于新课内容比较简单,和之前学习的知识关联性不大。它的优点是能迅速地把学生的思维和注意力吸引到新课要研究的问题上来。例如在讲“有理数的混合运算”时可这样导入:我们前面学习了有理数的概念,有理数
The introduction of the new course plays a role in the entire teaching process. The design of new courses in mathematics teaching to import, stimulate students interest in learning has become an urgent need for our mathematical teachers to study. Direct import method Teachers in class directly say the topics to be taught in this lesson. This import method is suitable for the new class content is relatively simple, and prior to the learning of knowledge is not associated. Its advantage is the ability to quickly draw students’ minds and attention to the issues to be studied in the new class. For example, when we talk about “mixed arithmetic of rational numbers,” we can import it in the following way: We have previously learned the notion of rational numbers, rational numbers
