GeoGebra是一种具有函数、几何、代数、微积分、统计学以及3D数学功能的图形计算器,是用于学习与教学的动态数学软件,可以这种动态几何软件上直接画点、向量、直线、图形,甚至是函数,而且还可以改变已画完物象的属性。GeoGebra的功能非常强大、使用也非常简单、具有非常强的交互性,可以用于学习、教学和考评。纵观我国中小学教学现状发现,空间与图形教学是教学的重难 GeoGebra is a graphical calculator with functions, geometry, algebra, calculus, statistics and 3D math functions. It is a dynamic mathematics software for learning and teaching. It can draw points, vectors, straight lines directly on this dynamic geometry software , Graphics, and even functions, but also can change the properties of the finished image. GeoGebra is powerful, easy to use and has very strong interactivity for learning, teaching, and evaluation. Looking at the status quo of primary and secondary schools in our country, we find that teaching in space and graphics is a difficult task
