本文综合笔者多年在数学教学相长中形成有关数型结合的方法,利用图形解决一些基本代数或者几何问题,使之方便,快捷。一、前提在中学数学中,四种数学思想贯彻全中学,其中数型结合是其中最重要的一种思想,而在中学的素质教育中,要把抽象的数学概念转化为形象的具体事务,是现在数学教育的一个重要方面,在数学解题中,数型结合可以把复杂的数学问题转化为几个简单的形象的数学问题加以解决,最后以简单的方式解决复杂的数学问题。笔者根据近年来在与学生的教学相长中,把其中经验加以总结,并结合今年在高考中出现的数学问题加以阐述。
This article combines the author for many years in mathematics teaching in the formation of the number of combination of methods, the use of graphics to solve some of the basic algebra or geometry problems, making it convenient and fast. First, the premise In high school mathematics, the four kinds of mathematical thinking implement the whole secondary school, in which the combination of number and type is one of the most important kind of thinking, and in quality education in secondary schools, abstract mathematical concepts into specific matters of the image, Is an important aspect of mathematics education nowadays. In mathematics problem solving, the combination of numbers and types can solve the mathematical problems of converting complex mathematical problems into several simple ones, and finally solve complex mathematical problems in a simple way. According to recent years, the author has summed up the experience with the students in the teaching, combined with the mathematical problems appearing in the college entrance examination this year.
