集书写、绘图功能于一体的电子白板不仅可方便的板书、绘制并组合图形,也可对图形进行拆分组合,不仅能感受常规图形是简单图形的组合,还能体会静中有动、动中有静的图形效果.所以数学教学也能同其他学科一样,利用电子白板方便的“接受、输出、交流”信息的功能助力于数学教学.一、通过对动、静图形的组合理解坐标系、实数对在画图窗口中绘制独立的平面直角坐标系并选择静止地理位置图片一副(如图1).在透明状态下将
Set of writing, drawing functions in one whiteboard not only convenient blackboard, drawing and combination of graphics can also split the graphics portfolio, not only can feel the normal graphics is a simple combination of graphics, but also to understand the static and dynamic There is static graphic effect, so the mathematics teaching can also be used in the mathematics teaching like the other disciplines, using the convenience of the whiteboard to “accept, output, exchange” information.One, through the combination of moving and static graphics understanding Coordinate system, real number Draw a separate plane Cartesian coordinate system in the drawing window and select a static geographical position picture (as shown in Figure 1) In the transparent state
