几何画板在中考数学中的应用

Application of The Geomet e r’s Sketchpad in Senior Middle School Entrance Mathematics Examination

用几何画板对中考数学题进行精准绘图,可通过点的动态演示得到相应点的轨迹或函数图像,在数学实验中进行直观探究、猜想并获得解题思路。运用几何画板辅助数学教学,不仅有利于提高数学教师信息技术与数学的深度融合能力,而且有助于培养学生的直觉思维与创新思维,实现学生的深度学习,进而切实减轻学生的学业负担。

The Geometer’s Sketchpad is used to accurately draw the math problems in the senior middle school entrance exam.The trajectory or function image of the corresponding points can be obtained through the dynamic demonstration of the points,and the ideas of solving the problems can be directly explored and guessed in the mathematical experiments.Using The Geometer’s Sketchpad to assist mathematics teaching is not only conducive to improving mathematics teachers’deep integration ability of information technology and mathematics,but also conducive to cultivating students’intuitive thinking and innovative thinking,realizing students’deep learning,and thus effectively reducing students’academic burden.
