利用“几何画板”研究函数的一些重要的性质,可以快速、精确、直观的显示出来,大大提高课堂效率。在高中立体几何教学中的应用,帮助学生理解和接受在平面中的三维空间图形,更能培养学生的空间想象能力。通过“几何画板”利用点的运动把几何图形生动的展现在学生面前,从而使学生直观看到的点的变化,也可以容易决定如何建立适当的平面直角坐标系。能进一步的培养学生利用数形结合来解决解析几何问题的能力。
The use of “Geometric Sketchpad ” to study some of the important properties of the function can be displayed quickly, accurately and intuitively, greatly improving classroom efficiency. In high school three-dimensional geometry teaching application, to help students understand and accept the three-dimensional graphics in the plane, but also to develop students’ spatial imagination. Through the “geometric drawing board ” the use of point movement to vividly present the geometry in front of students, so that students can intuitively see the point of change, but also can easily determine how to establish the appropriate plane Cartesian coordinate system. Students can further develop the ability to solve the problem of geometric analysis by using the combination of number and shape.
