试题改编是指对已有试题的数据、面貌、内涵等方面进行合理改造,进而得到所需试题的过程,这是试卷命题中常用的一种手法.试题改编是一个推陈出新的过程,下面笔者结合自己的实践来肤浅地谈一谈其常用的一些手法.1从题中数据入手换据、赋值、引参数据是数学运算的起点,改变题中数据是进行试题改编最为直接的手段,其常用手法如下:手法1换据.即不改变题目的框架,只改变其中的一些主要数据,使之成为一道新题.这种改编手法简单而快捷,在命题中常用,其缺点是试题
The test questions adaptation refers to the process of reasonably rebuilding the data, appearance and connotation of the existing test questions so as to obtain the required test questions, which is a common practice in test paper propositions. The test questions adaptation is an innovation process. Own practice superficial to talk about some of its commonly used techniques .1 data from the title to start with, assignment, reference parameters is the starting point of mathematical operation, the data in the question is the most direct means of adapting the questions, and its commonly used The method is as follows: Manipulation 1 for the data, that does not change the framework of the subject, only change some of the main data, making it a new topic. This adaptation is simple and quick, commonly used in the proposition, the disadvantage is the test
