开放题是富有极大教育价值的一种数学问题的题型,它的出现是时代呼唤的结果.数学开放题的编制常用的方法有:弱化陈题的条件,使其结论多样化;隐去陈题的结论,使其指向多样化;在既定的条件或关系下,探讨多种结论;给出结论,寻求使结论成立的充分条件;比较某些对象的异同点;在既定的条件或实际情景中,设计解决某些问题的方案.
The open question is a type of math problem rich in great educational value, and its appearance is the result of the call of the times.Many commonly used methods in the preparation of the open question of mathematics include: weakening the conditions of the thesis and diversifying its conclusion; Chen’s conclusion, to make it point to diversity; under the established conditions or relations, to explore a variety of conclusions; to give conclusions to seek sufficient conditions to establish the conclusion; comparison of similarities and differences between certain objects; in the established conditions or actual Scenario, design solutions to certain problems.
