1问题呈现前苏联数学教育家奥加涅相说过:“必须重视很多习题潜在着进一步扩展其数学功能、发展功能和教育功能的可行性.”中学数学教材中的例习题凝聚了几代专家、学者的集体智慧和结晶,研究这些例习题,充分挖掘其内在功能的教育教学价值是一线教师责无旁贷的任务.课本上一些看似平淡无奇的例习题,隐藏着深远的背景,也许有着意想不到的功能.如果对教材中的例习题仅停留在它的表面,而不探究它的本质,那么就会失去例习题的内涵与新意,
1 The question presents the former Soviet mathematics educator Ogashaye said: “We must attach importance to many exercises potential to further expand its math function, the development of functional and educational functions of the feasibility.” On behalf of the experts and scholars collective wisdom and crystallization, the study of these exercises, to fully tap the value of education and teaching of its intrinsic function is the task of front-line teachers duty-bound books on some seemingly bland examples of exercises, hidden far-reaching background, perhaps Has an unexpected function.If the sample exercises in the textbook only stay on its surface, without exploring the essence of it, it will lose the connotation of the exercises and new ideas,
