数学的概念是反映并确定客观世界中的数量关系和空间形成一般本质属性的思维形式。数学概念是数学基础知识的基础,概念教学在教学中占据重要地位,正确地理解和掌握数学概念是掌握数学知识的前提,是计算、推理和绘图的必要基础,是发展智力和培养能力的重要途径。进行数学概念教学,我一般采取如下几种方法。 1.讲清含义,使学生能正确理解数学概念具有高度的抽象性、严密的逻辑性和应用的广泛性。要求教师必须准确地讲清概念,包括含义适用范围及概念间的联系、区别等。例如,函
The concept of mathematics is a form of thinking that reflects and determines the quantitative relations in the objective world and the space that forms the general essential attributes. The concept of mathematics is the foundation of the basic knowledge of mathematics. Concept teaching occupies an important position in the teaching. To correctly understand and master the concept of mathematics is the precondition of grasping mathematics knowledge. It is the necessary basis for calculation, reasoning and drawing. It is important to develop intelligence and cultivate abilities. way. Mathematics concept teaching, I generally take the following methods. 1. clarify the meaning so that students can correctly understand the mathematical concept of a high degree of abstraction, strict logic and the application of the extensive. Requirements teachers must be clear about the concept, including the meaning of the scope and concept of the relationship between the differences. For example, letter
