在研究数学的时候,往往要从“数”、“形”这两个方面来进行。所谓数形结合就是借助数与形之间的对应与转换来将相关的数学问题解决掉。通过数形结合不仅可以将复杂的问题简单化,又可以将抽象的问题具体化,以此来让学生在最快的时间完成数学作业。一、题组教学中运用数形教学法数学课堂教学过程中,教师要从学生的认知规律出发,选择一组有效的数学问题来开展教学活动。在解决这一组数学问题的时候,教师要借助数形教学法,分析它们的相同点以及不同点,提高学生的思维能力。比如:当学生在学习二次函数、二次方程以及二
In the study of mathematics, often from “number ”, “form ” these two aspects. The so-called number-shape combination is the number and shape with the correspondence between the conversion to the relevant mathematical problems out. By combining numbers and forms, you can not only simplify complicated problems but also abstract the abstract problems so that students can finish their math homework in the shortest time. First, the group teaching the use of digital teaching Mathematics classroom teaching process, teachers from the cognitive rules of students, choose a set of effective mathematical problems to carry out teaching activities. In solving this set of mathematical problems, teachers should use digital teaching methods to analyze their similarities and differences, and to improve their thinking ability. For example: When students are learning quadratic functions, quadratic equations and two
