通常传统的数学题型,是将已知条件全部罗列出来,要求学生求得一个或几个未知的答案.由于人们做这种数学题不需要思考已知条件是哪里来的、不需要思考能否用多种方法解决数学问题、不必思考几个已知条件能够得到多少未知的答案等,所以这种数学题型容易让人形成一个封闭式的思路,为了突破传统数学习题的弊端,初中数学教师可以设计一些尝试题让学生思考,所谓的尝试习题,即它的条件、方法、答案等都是开放式的,做这种题型能够让学生得到更多的思考.
Generally, the traditional math problems list all the known conditions and ask the students to find one or several unknown answers. Because people do not need to think about where the known conditions come from, they do not need to think Whether to solve mathematical problems in a variety of ways, do not have to think about how many unknown conditions can be given a few known conditions, so this type of mathematics is easy to form a closed idea, in order to break the shortcomings of traditional mathematics exercises, junior high school mathematics Teachers can design some try questions for students to think. The so-called try exercises, that is, its conditions, methods, and answers are all open-ended. This kind of questions can make students think more.
