数学概念是学好数学知识的基础,正确全面地理解和掌握数学概念是学好数学的基础。在数学教学过程中,概念教学占有十分重要的地位。但在具体教学中往往容易出现一些偏差。如对概念教学应该达到的目的不明确;忽视概念教学的条件和背景;忽视概念间的联系,使概念孤立起来等等。这种教法的结果使学生对概念只会死记硬背,不能正确地理解和灵活地运用,当然更谈不上能力的发展。这是违背新教育理念的。一、注重数学概念的有效引入
The concept of mathematics is the basis for learning maths knowledge. It is the basis of maths to understand and master math concepts correctly and comprehensively. In the teaching of mathematics, concept teaching occupies a very important position. However, some deviations tend to occur easily in specific teaching. Such as the concept of teaching should achieve the purpose is not clear; ignore the conditions and background of the concept of teaching; ignore the connection between concepts, the concept of isolation and so on. The result of this teaching method is that students will only memorize the concept, can not correctly understand and flexibly use, of course, let alone the development of ability. This is against the concept of new education. First, pay attention to the effective introduction of mathematical concepts
