了解和掌握数学题的命制,无论是对数学教学,还是数学解题,都有着积极的意义。《中学数学教学参考》的“命题研究”栏目经常有介绍如何命题的文章,笔者读后深受启发。一道高质量原创试题的产生往往需要几位教师花几天时间几经修改才能完成,尤其是应用题和有一定难度的压轴题的命制,会花费命题者很多的时间和精力。对于一线教师,他们的教学任务都很繁重,如此命题或许只能是偶尔为之。笔者作为一名基层的教研
Understanding and mastering the life of math problems has a positive meaning both for maths teaching and for solving math problems. “High School Mathematics Teaching Reference” “Propositional Research ” column often describes how the proposition of the article, the author was inspired. The production of a high quality original test often requires several teachers to spend several days time to complete several modifications, especially the application of the title and a certain degree of difficulty of the finale of the title of the system, will cost a lot of time and energy of the proposition. For first-tier teachers, their teaching tasks are very heavy, so the proposition may only be occasional. The author as a grass-roots teaching and research
