要学好数学这门学科,正确地理解数学中的各类概念是关键。圆中的概念特别多,而且圆这一节非常重要,圆为三角形的运用及化归思想的培养,以及巩固和深化“图形变换”的教学提供了理想的平台。此外,圆在现实生活中还有着广泛的应用,为培养学生的应用意识和解决实际问题的能力提供了很好的载体。所以在中考中,圆颇受青睐。而要学好圆这一章内容,理解概念是必须做好的一个工作。下面笔者就圆中概念方面易错题进行收集、分析,示例如下。
To learn mathematics this discipline correctly understand the various concepts in mathematics is the key. The concept of the circle is particularly large, and the circle is very important. The circle provides an ideal platform for consolidating and deepening the teaching of “transformation of the triangle” through the application of triangles and the transformation of thought. In addition, the circle has a wide range of applications in real life, providing a good carrier for cultivating students’ awareness of application and solving practical problems. So in the exam, the circle quite popular. To learn a good round chapter of this chapter, to understand the concept is a must do a job. The following author on the concept of the circle of error-prone collection, analysis, examples are as follows.
