所谓“新定义”型问题,主要是指在问题中定义了中学数学中没有学过的一些概念、新运算、新符号,要求学生读懂题意并结合已有知识、能力进行理解,根据新定义进行运算、推理、迁移的一种题型.这类题目具有启发性、思考性、挑战性和隐蔽性等特点,构思巧妙,题意新颖,是考察学生综合素质,挖掘学生潜力的较佳题型,受到命题者的青睐.纵观近几年的高考试题,可以发现,“新定义”型问题按命题背景可分为三种类型:以新课标内容为背景、以高等数学为背景、以跨学科为背景.
The so-called “new definition ” type of question, mainly refers to the definition of the problem has not been learned in high school mathematics concepts, new computing, new symbols, require students to read the title and combined with existing knowledge and ability to understand, According to the new definition of computing, reasoning, relocation of a type of questions. Such topics are inspiring, thinking, challenging and covert characteristics, ingenuity, novelty, is to examine the overall quality of students to tap the potential of students According to the proposition background, we can find that the “new definition” type questions can be divided into three types according to the proposition background: taking the content of the new curriculum as the background, Higher mathematics as the background, interdisciplinary background.
