虽然“画一个图表”被提倡为一个有用的解决问题的策略，但生成一个适当的图表对许多学生来说是有问题的。本个案研究探讨小学生对新问题产生图解的困难。确定了三类困难：（1）不使用图表;（2）图表的一般困难和（3）与特定图表有关的特殊困难。结果表明，有必要在图表使用的教学，使学生和解决他们的困难。需要特别注意的是：（1）图形与图像的区别;（2）图的歧义;（3）图的动态特征。背景
Although "draw a diagram" is advocated as a useful problem- solving strategy, generating an appropriate diagram is problematic for many students. This case study explored primary-aged students' difficulties in generating diagrams for novel problems. Three categories of difficulties were identified: (1) non-use of diagrams; (2) generic difficulties with diagrams and (3) idiosyncratic difficulties that were related to specific diagrams. The results suggest that there is a need for instruction in diagram use to empower students and address their difficulties. Specific attention needs to be given to: (1) the diagram-picture distinction; (2) the ambiguity of diagrams; and (3) the dynamic feature of diagrams. Background
