借助图形语言、符号语言以及逻辑语言来分析应用题的内在数量关系是解决代数应用题的关键。代数应用题是中学数学中的重点和难点,也是培养学生思维能力的重要工具,因为解答应用题的过程不仅可以综合训练学生的抽象思维,而且可以综合训练学生的形象思维。由于解答应用问题时涉及转化、比对、分析、综合、假设、尝试、猜想、验证、推算等思维过程,对学生的逻辑思维能力要求较高,所以很多学生面对应用题时(尤其较复杂的应用题),常常感觉到
It is the key to solve the problem of algebra using the analysis of the relationship between the number of the internal and the number of the applied questions by means of graphic language, symbolic language and logical language. The algebra application is an important and difficult point in middle school mathematics. It is also an important tool to train students’ thinking ability. Because the process of answering application questions can not only comprehensively train students’ abstract thinking, but also comprehensively train students’ image thinking. Because of the thinking process of transformation, comparison, analysis, synthesis, hypothesis, try, guess, verification, estimation and so on, there are high demands on students’ logical thinking ability when answering application questions, so many students face the problem of application (especially complicated) The application of the title), often feel
