人教版在七年级下册第六章引入了平面直角坐标系,为以后学习函数作铺垫.由于学生刚刚接触数形结合思想,看似简单,但学生对点的特征、点的距离、点的对称、点的平移等基础知识要点,容易记错位.本文就作者几年的初中教学经验,总结出诗歌教学法,能生动、有趣地讲解平面直角坐标系的知识要
PEP in the seventh grade under the sixth chapter introduced a rectangular Cartesian coordinate system, paving the way for future learning function.Because the students just contact with the number-shape combination of thinking, seemingly simple, but the characteristics of the students point, point distance, point The translation of the point of the basic points of knowledge, easy to remember the wrong place.Based on the author’s junior high school teaching experience for several years, summed up the poetry teaching method, vivid and interesting to explain the knowledge of planar Cartesian coordinate system
