概念是思维的基本形式,具有确定研究对象和任务的作用。数学概念则是客观事物中数与形的本质属性的反映。数学概念是构建数学理论大厦的基石,是导出数学定理和数学法则的逻辑基础,是提高解题能力的前提,是数学学科的灵魂和精髓。好的数学概念课教学,能使学生透彻、牢固地掌握数学概念,提高数学能力的关键所在。中学数学教师应该充分认识到数学概念 Concepts are the basic form of thinking and have the role of identifying research objects and tasks. The concept of mathematics is the reflection of the essential attributes of number and shape in objective things. The concept of mathematics is the cornerstone of the building of a mathematical theory building. It is the logical foundation for the derivation of mathematical theorems and mathematical rules. It is a prerequisite for improving the ability to solve problems and is the soul and essence of mathematics. Good mathematics concept teaching can enable students to thoroughly and firmly grasp the concept of mathematics and improve the key to mathematics ability. Middle school mathematics teachers should fully understand the concept of mathematics
