教学思想方法是数学之精髓,是解决数学问题的理论指导。教师在教学过程中针对问题要授之以“渔”而非授之以“鱼”。在高中数学教学中方法很多。数形结合方法不仅作为一种解题方法,并且是数学思想方法中最基本、最重要的教学思想。数形结合能力的提高,有利于从数与形的结合上深刻认识数学问题的实质,本文通过实例介绍了数形结合思想方法的运用技巧。
Teaching thought and method is the essence of mathematics and is the theoretical guidance for solving math problems. In the course of teaching, teachers are required to teach “fishing” rather than “fish”. There are many ways to teach mathematics in high school. The combination method of number and shape is not only a method of solving problems, but also the most basic and important teaching thought in mathematical thinking methods. The improvement of the combination of number and shape is conducive to the profound understanding of the essence of mathematics problems from the combination of number and shape. This article introduces the application skills of the number and shape combination method.
