高中数学作为注重实践的科目,若仍使用传统的教学模式,不但会降低学生的学习积极性,还会降低教学质量。因此,数学教学中应重视数形结合法,便于将抽象思维转变为具象思维,帮助学生掌握更多的数学知识,提高数学成绩。下面,从数形结合的概念、作用出发,总结数形结合法在数学中的运用。 High school mathematics as a practice-oriented subjects, if still using the traditional teaching mode, not only will reduce the enthusiasm of students, but also reduce the quality of teaching. Therefore, mathematics teaching should pay attention to the combination of digital form, easy to abstract thinking into concrete thinking, to help students master more mathematical knowledge, improve math performance. Next, from the concept of digital form combination, the role of summation of the number of combination method in mathematics.
