問題的来源和調查結果我們在“关于平面几何‘标准图形’教学的消极作用的問題”的研究中,察觉到“标准图形”教学对解变式图形題所产生的消极作用最严重的是在学习几何基本概念部分,但是到了学习三角形及四边形时,就仅仅影响感知过程和思維过程,而很少影响到思維結果。在这个研究的同时,我們还发現綫段間隔或交錯图形对解題的消极影响也是相当严重的。 The source of the problem and the survey results In our study of the “negative effects of the teaching of the plane geometry” standard graphics, we found that the most serious negative effect of “standard graphics” on the problem of the " Learning the basic concepts of geometry, but learning triangle and quadrilateral, only affects the perception process and thinking process, and rarely affect the thinking results. At the same time as this study, we also found that the negative effects of line segments or interlaced graphics on problem solving were also quite serious.
