相关题,指的是具有相同前提的一组子题,这是数学中一种常见的综合题型,它涉及的知识面广,条件错综复杂,问题灵活多变,在很多相关题中,为了降低难度,减小坡度,同时又要考查到同学们是否具有潜在的观察能力、创造性思维能力和自学能力,所设计的子题都具有一定的“台阶”性,使得前一子题对后一子题的解决有条件铺垫、方法暗示等作用。明确子题的“台阶”功能,对于问题的解决有着重要的导向 Related questions refer to a set of sub-questions that have the same premise. This is a common comprehensive question in mathematics. It involves a wide range of knowledge, complicated conditions, and flexible and varied problems. In many related questions, in order to reduce Difficulty, reducing slope, and at the same time, it is necessary to examine whether the students have potential observation ability, creative thinking ability, and self-learning ability. The designed subtopics all have a certain degree of “step”, making the former sub-subject to the latter sub-subject. The problem is solved by conditional matting and method hinting. The “step” function of the sub-question has an important orientation for the solution of the problem.
