数学练习对巩固数学知识、发展数学能力、培养数学情趣等有着十分重要的意义,但它离不开数学练习题的设计与编制。本文以“比例尺”为例,着重谈谈对本节编题的认识与做法:我将本节的题型分为四种类型:一是辨析题:根据概念、公式、性质、规律、数量关系以及图形的特征来编题;二是操作题:根据本节涉及的动手操作的内容进行编题;三是课后练习修改题:将课本中的练习进行修改,将封闭题改为开放题,或将目标单一题改为目标多元的题等;四是综合应用题:
Mathematical exercises are of great significance in consolidating mathematical knowledge, developing mathematical abilities, developing mathematical taste, but it can not be separated from the design and compilation of math exercises. This article takes “scale ” as an example, focusing on the understanding and practice of this section of the topic: I will be divided into four types of questions in this section: First, the analysis of questions: According to the concept, formula, nature, law, quantity Relationship and the characteristics of the graphics to the second; the second is the operation of the title: This section involves the content of the hands-on operation of the title; Third, after-school practice to modify the question: the textbook exercises to modify the closed question into an open question , Or the goal of a single question into multiple goals and so on; Fourth, the integrated application of questions:
