近几年来,我们在数学教学中,启发思维,发展智力,培养学生学习的主动性和积极性,做了些尝试,获得了较好的效果。现就《全日制十年制学校初中数学课本(试用本)》第一、二,三册有关内容,谈几点做法。一、重视培养学生的观察能力概念是思维的基本单位,只有正确地掌握概念,才能正确地进行思维。在概念教学中,我们有意识地引导学生对展示的直观材料进行观察,让他们发现事物的特征,从而掌握新概念。例如“三角形”教学中,为了讲清“对应”的概念,我们先让学生观察两个完全重合的三角形模具,引导他们用自己的语言描述和解释所观察的对象,弄清全等三角形对应顶点、对应边、对应角的意义,然后摈弃某
In recent years, we have made some attempts and obtained good results in mathematics teaching by inspiring thinking, developing intelligence and cultivating students' initiative and enthusiasm. Now on the “full-time 10-year school junior high school math textbooks (trial version)” the first, second and third volumes of the content, talk a few practices. First, pay attention to developing the concept of student observation ability is the basic unit of thinking, and only correctly grasp the concept, can correctly thinking. In concept teaching, we consciously guide students to observe the visual materials of the exhibition, let them discover the characteristics of things, so as to grasp the new concepts. For example, in the teaching of “Triangle”, in order to clarify the concept of “correspondence”, we first let students observe two completely overlapping triangular molds and guide them to describe and explain the observed objects in their own language and find out the corresponding vertices of congruent triangles , The corresponding edge, corresponding to the meaning of the corner, and then discard some
