【活动背景】本次活动是在同学们学习了《平面直角坐标系》一章后,了解了坐标系中对称点的坐标特点的情况下,利用几何画板软件,探究关于坐标轴夹角平分线对称的点的特点.将现代信息技术与数学实验融合起来,通过操作、观察、归纳、类比等活动发现规律,猜想结论,发展合情推理能力,并认识到结论的正确性要通过推理来确认.【课前准备】笔记本电脑数台,要安装几何画板软件,装有投影设备的教室.【活动过程】活动一:观看老师的操作步骤,模仿
【Activity Background】 After learning the chapter “Plane Cartesian Coordinate System”, the students learned about the coordinate characteristics of the symmetry point in the coordinate system. By using the geometric drawing software, Symmetry points of the characteristics of the modern information technology and mathematical experiments together, through the operation, observation, induction, analogy and other activities to discover the law, guess the conclusions, the development of emotional reasoning ability and recognize that the conclusions of the correctness of the reasoning to be confirmed by reasoning . [Pre-class preparation] Several laptops, to install geometric drawing board software, equipped with projection equipment classroom [activity process] Activity one: watch the teacher’s steps to imitate
