“应用数对确定位置”学习体验案例探讨

Learning Experience Case on Applying Coordinate to Determine Position

学生在教师的引导下,借助数形结合的思想,经历确定点的位置的探究过程。学生以一维"数射线"上确定点的位置为基础,拓展到二维平面确定点的位置,经历了直角坐标系的再发现过程。

With the help of teacher, the students experience the inquiry process on applying coordinate to determine position the location of points. From the point on number line to the point in flat, the students rediscovery of the Cartesian coordinate system.
