类比就是类似比较。在数学教学中,经常要将已学过的旧课与要学的新课相比较,指出其共同点或者指出相类似的地方。如讲乘数是三位数的乘法这种新知识时,要将它与乘数是两位数的乘法相类比。使学生通过知识之间的内在联系,在掌握旧知识的基础上更容易接受新知识。如果经常运用类比,使学生巩固地掌 Analogy is a similar comparison. In mathematics teaching, it is often necessary to compare old lessons learned with new courses to be taught, to point out similarities or points to similarities. In the case of the new knowledge of multiplication, which is a three-digit multiplier, it is analogous to the multiplication of two-digit multipliers. It is easier for students to accept new knowledge based on the old knowledge through the internal connection between the knowledge. If you often use analogy, so that students consolidate their hands
