唯物辩证法认为:客观事物是互相影响、互相作用、普遍地联系着。数学中应用题的数量关系也是这样的,条件与条件之间、条件与问题之间,总是直接地或间接地、明显地或隐蔽地相互联系着。分析应用题实际上也就是运用辩证法去寻找、挖掘和重新组合题中所给的数量以及它们之间的种种联系。以下对应用题数量间关系的分析与运用谈几点体会:一、运用线段图,帮助学生明确数量间的联系应用题中有的所提供的条件不直接,通过线段图提示,可以
Materialist dialectics hold the view that objective things are mutual influence, interaction and universality. The relationship between the number of questions in mathematics is the same, between conditions and conditions, between conditions and problems, always directly or indirectly, obviously or covertly linked to each other. In fact, the analysis of application questions is the use of dialectics to find, excavate and regroup the questions given in the number and the various links between them. The following questions on the relationship between the number of applications and analysis of how to talk about a few experiences: First, the use of line segments to help students a clear relationship between the number of questions provided by the application is not direct, through the line segment tips, you can
