几何画板在小学数学教学中的应用实践

Application of Geometry Sketchpad in Mathematics Teaching in Primary Schools

数学相比其它学科是一门抽象且要求准确的学科,从小学到初中乃至高中数学的教学过程中,无论是几何教学还是代数教学,都运用到了"数形结合"的思想。那么如何在教学过程中"寓数于形"或"寓形于数"呢?在信息不发达的年代取决于数学教师自身是否拥有扎实的基本功,但是随着计算机科学技术的不断发展,教学手段的不断多样化以及多媒体教学的引入,使得数学教学工作变得简单。依托计算机科学和图形学的几何画板软件工具的出现很好地解决了数与形的配合,有利于教学效率的提高。本文重点以小学数学教学过程中几何画板软件的几点应用为例做出简要剖析。

compared with other subjects, mathematics is an abstract and accurate subject. In the teaching process of mathematics from primary school to junior high school, it is not only geometry teaching but also algebra teaching. All of them are applied to the thought of "combination of number and form". So how to "put number in form" or "form in number" in the teaching process? In the age of undeveloped information, it depends on whether mathematics teachers have solid basic skills, but with the continuous development of computer science and technology, the continuous diversification of teaching methods and the introduction of multimedia teaching, Make the teaching of mathematics easy. The Development of geometric Sketchpad Software tool based on computer Science and Graphics This paper focuses on the application of geometric Sketchpad software in mathematics teaching in primary school as an example to make a brief analysis.
