数学概念是反映一类对象空间形式和数量关系方面本质属性的思维形式。它是数学知识的基础,是数学思想与方法的载体。教学大纲指出:“正确理解数学概念是掌握数学基础知识的前提。”在数学教学实践中体会到:加强数学概念教学,既可以使学生加强对数学理论知识的理解,又可以培养学生逻辑思维能力,因而显得尤其重要。
Mathematical concepts are the forms of thinking that reflect the essential attributes of a class of objects in relation to their spatial form and quantity. It is the basis of mathematical knowledge, is the carrier of mathematical ideas and methods. The syllabus states: “Correct understanding of mathematical concepts is the prerequisite for grasping the basics of mathematics.” In the practice of mathematics teaching, we understand that to strengthen the teaching of mathematical concepts can not only enhance students ’understanding of mathematical theory, but also develop students’ logic Thinking ability, therefore, is particularly important.
