一、利用图形进行概念教学,帮助学生辨析数学概念数学概念是揭示数学对象空间形式和数量关系内在属性的一种基本思维形式,它是数学定理、公式、法则形成的重要基础,是数学推理、判断、猜想的主要依据.高中数学教学中蕴涵着许多至关重要的数学概念,如集合、函数、算法、数列、椭圆、导数、三角函数、平面向量、双曲线、不等式等概念.在概念教学时,由于这些概念比较抽象,采用传统的教学方法,容易造成学生对概念含糊不清,一知半解,无法使 First, the use of graphic concepts to help students identify mathematical concepts Mathematical concepts is to reveal the inherent properties of mathematical objects spatial form and quantity relations of a basic form of thinking, which is mathematical theorems, formulas, laws form an important basis for mathematical reasoning, Judgment, guess the main basis.Mathematics teaching in high school contains many of the most important mathematical concepts, such as set, function, algorithm, sequence, ellipse, derivative, trigonometric function, plane vector, hyperbola, inequality and other concepts.In the concept of teaching When these concepts are rather abstract, the use of traditional teaching methods easily lead to ambiguity of the concept of students
