平面几何是培养学生逻辑思维能力的重要学科之一,学好平面几何对提高学生分析能力和逻辑思维能力具有深远的意义。但对于初学几何的学生来说往往感到很不习惯。几何语言、图形、论证训练是几何教学中的重要任务,也是几何入门教学的难点所在。因此入门教学是学好平几的第一个难关,为了减少初学时的困难,我根据新的数学课程标准采取了逐步过渡的办法,即分散难点,适当渗透,多次反复,逐步提高,收到了理想的效果。
Plane geometry is one of the important disciplines to cultivate students’ logical thinking ability. Learning plane geometry has far-reaching significance for improving students’ analytical ability and logical thinking ability. But for beginners, students often feel very uncomfortable. Geometry language, graphics, and argumentation training are important tasks in geometry teaching. They are also the difficulties in teaching geometry. Therefore, introductory teaching is the first difficult task to learn peace. In order to reduce the difficulties of beginners, I took a gradual transition approach according to the new mathematics curriculum standards. That is, to diffuse difficulties, properly penetrate, repeatedly repeated, gradually improve, and received Ideal effect.
