一、理解性困难及其克服这种类型的困难究其原因是由于对复合应用题的不理解而造成的。也就是说，当学生遇到复合应用题时，看不出题目中的数量关系，哪些是已知量，哪些是未知量，眼巴巴地看着有些惘然，对各种数量之间的关系更不可知。对于这种困难，教师应帮助学生正确理解题意，仔细地分析，找出有关能反映数量关系的词语，首先应把它分解成几个有连续性的简单应用题，逐个进行解答。这样由易到难，由简单到复杂。还要让学生懂得解答复合应用题的关键是通过分析已知条件和问题的数量关系，找出需 First, understand the difficulties and overcome this type of difficulty The reason is due to the lack of understanding of composite application problems. In other words, when students encounter compound application questions, they cannot see the quantitative relationships in the topics, which are the known quantities, which are the unknown quantities, and they look guilty in a dazed manner, and are even more incapable of the relationship between various quantities. know. For such difficulties, teachers should help students understand the meaning of the questions correctly, analyze them carefully, and find out the words that can reflect the quantitative relationship. First, it should be decomposed into several simple application questions that have continuity, and they should be answered one by one. This is easy to difficult, from simple to complex. The key to letting students know how to answer complex application questions is to find out what needs to be done by analyzing the quantitative relationship between known conditions and problems.
