数学概念是数学教材结构的最基本的要素,正确理解数学概念,是掌握数学基础知识的前提。学生如果不能正确地理解数学中的各种概念,就不能很好地掌握各种法则、公式、定理,也就不能应用所学知识去解决实际问题。数学概念的教学是整个数学教学的一个重要环节,正确地理解数学概念是掌握数学知识的前提。教师只有把数学概念讲清楚、讲准确,让学生深刻理解概念的内涵,准确掌握概念的外延,才能使学生从根本上提高分析问题和解决问题的能力。因此,抓好数学概念的教学,是提高数学教学质量的关键。
The concept of mathematics is the most basic element of the structure of mathematics teaching materials. Correct understanding of mathematical concepts is the precondition of mastering the basic knowledge of mathematics. If students can not correctly understand the various concepts in mathematics, they can not master all kinds of laws, formulas and theorems well and can not apply what they have learned to solve practical problems. The teaching of mathematical concepts is an important part of the whole mathematics teaching. Correct understanding of mathematical concepts is the prerequisite for mastery of mathematical knowledge. Teachers only make clear the mathematical concepts, accurate, so that students understand the concept of a deep understanding of the concept of accurate grasp of the extension in order to enable students to fundamentally improve the ability to analyze and solve problems. Therefore, to grasp the teaching of mathematical concepts is the key to improve the quality of mathematics teaching.
