在高中数学的学习中,需要注意在思考和解决问题的过程中,“数”与“形”往往是不能分开的,尤其是一些较为复杂的问题,更是需要两个方面相互利用、相互转化.有的题目以图为主,但在图形结构中蕴含着一定的数量关系式,可以将几何问题代数化,利用代数的算法优势,以数助形,以解决问题.本文通过对数形结合法的分析,明确数形结合法在高中教学中的作用,并给出几个具体的教学案例,通过对具体案例和方法的思考,来认识和了解数形结合的思想.
In high school mathematics learning, we must pay attention to the process of thinking and solving problems, “number ” and “form ” often can not be separated, especially some of the more complex issues, but also need two aspects of each other Use, transform each other.And some topics to map the main, but in the graphics structure contains a certain number of relations, the geometric problems can be algebraic, the use of algebraic algorithm to help shape the number of aids to solve the problem.In this paper, The analysis of logarithmic conjunctive method clarifies the role of the method of number combining in high school teaching, and gives several specific teaching cases. Through the consideration of specific cases and methods, we can understand and understand the idea of digital conjunctions.
