有一类考察学生阅读理解能力的解答题,要求学生能把生活实际问题构建成一次函数、不等式等数学模型来解决问题.这类题目往往语言叙述冗长,数据繁多,同学们审题时易烦躁,往往读到一半就不想读下去了,有的同学尽管读完题目,但是不知所云.在实际教学过程中,采用平行四边形框架图帮助学 There is a class of exam questions that examine students’ ability to read comprehension, asking students to construct practical problems into first-order functions, inequalities and other mathematical models to solve the problems. These topics tend to be verbally verbose and have a wide range of data. Read half did not want to read on, and some students although reading the title, but unintelligible.In the actual teaching process, the use of parallelogram frame to help learn
