课堂教学是发展学生思维的过程,思维能力的发展需要长期的培养和训练。教学中引导学生把“旧知”与“新知”进行比较,找到新旧之间的联系和区别,学生思维得到充分发挥,加深了对知识的理解,有利于牢固掌握新知。发展思维、培养能力是数学教学永恒的主题,在小学数学教学中,要重视比较法的运用。一、比较条件与问题,培养思维的准确性比较是学生各种认识和各种思维的基础。有比较才有辨别,因此,在教学中对只有一句之差、一字之别的相关习题,教师要让学生在比 Classroom teaching is the process of developing students’ thinking. The development of thinking ability needs long-term training and training. In teaching, students are guided to compare “old knowledge ” with “new knowledge ” to find out the relationship between old and new, and their differences. Students’ thinking can be fully exerted, their understanding of knowledge deepened, and the new knowledge can be firmly grasped. Developing thinking and cultivating ability are the eternal themes of mathematics teaching. In primary mathematics teaching, we should pay more attention to the application of comparative law. First, the comparison of conditions and problems, to develop the accuracy of thinking is a variety of students a variety of understanding and thinking of the foundation. There are more than a distinction, therefore, in teaching on only one difference, one word other than the relevant exercises, teachers should let students in the ratio
