数学概念是数学知识之本,解题之源,学好它既是基础又是关键。理解掌握概念的过程是学生提高学生能力的重要途径,所以学好数学概念极为重要。对于初中一年级的学生来讲,思维是以形象化为主,而数学概念却具有高度的抽象性,如何根据学生的智力水平,巧用电教媒体,调动学生的多种感官,将数学中的知识变抽象为形象,变复杂为简单,变难懂为易学,使学生轻松愉快地理解和掌握知识呢?这里以怎样能很好地运用数学概念来谈谈自己的肤浅认识。
The concept of mathematics is the foundation of mathematics knowledge and the source of problem solving. Learning it is both fundamental and critical. Understanding the process of mastering concepts is an important way for students to improve their abilities, so learning math concepts is extremely important. For the first-year junior high school students, thinking is based on visualization, while the mathematical concept has a high degree of abstraction. How to use the audio-visual media skillfully to mobilize students’ various senses according to their intelligence level Knowledge becomes abstract as an image, becomes complicated as simple, and becomes difficult to understand as easy to learn, so that students can understand and master knowledge easily and happily? Here is how to use mathematical concepts to talk about their superficial understanding.
