“几何画板”是由美国Key Curriculum Press公司研制并出版的几何软件,是一款先进的优秀教学软件。它以点、线、圆为基本元素,通过对这些基本元素的变换、构造、测算、计算、动画和跟踪轨迹等方式,显示或构造出较为复杂的图形。掌握它不仅能激发学生学习数学的兴趣,还能帮助学生更准确、深刻地探究数学知识,解决数学问题。 “Geometric Sketchpad ” is a geometric software developed and published by the United States Key Curriculum Press, is an advanced and outstanding teaching software. It points, lines, circles as the basic elements, through the transformation of these basic elements, construction, calculation, calculation, animation and tracking trajectory, etc., to display or construct a more complex graphics. Mastering it can not only stimulate students’ interest in math, but also help students to explore maths more accurately and profoundly and solve math problems.
