一、教学内容分析“圆”是初中几何的提高阶段,“圆与圆的位置关系”处于这一章的后半部分,在此之前已学习过圆的许多重要的性质和定理,以及点和圆的位置关系、直线和圆的位置关系.因此,在教学上存在“温故”和“知新”两方面的要求,教学内容突出显示了“数形结合”的重要思想.通过这节课的数学活动培养学生综合运用知识的能力,对学生进行事物之间相互联系和运动变化的观点的教育,树立科学的辩证唯物主义世界观和人生观.
First, the teaching content analysis “round ” is the junior high school geometry to improve the stage, “the relationship between the circle and the circle ” in the second half of this chapter, before this round has learned a lot of important properties and theorems , As well as the relationship between the point and the circle, the relationship between the line and the circle.Therefore, there are two kinds of requirements in the teaching such as “warm allusions ” and “new knowledge ”, the teaching content highlights Through the mathematics activities in this lesson, we should cultivate students’ abilities to comprehensively use knowledge, educate students about the interrelationships between things and the viewpoint of sports change, and establish a scientific dialectical materialist world outlook and outlook on life.
