“图形与几何”是初中数学的重要内容,解决图形与几何类问题往往是以正确的识图为先导的,借助图形直观可以把复杂的数学问题变得简明、形象,有助于探索解决问题的思路、预测结果,可以帮助学生直观地理解数学,在整个数学学习过程中都发挥着重要作用,但受知识、经验和方法的局限,学生在解决图形与几何类问题时,常常会犯一些被图形直观假象蒙蔽的错误,现针对此类典型错误进行分类剖析,寻找原因,并提出
“Graphics and Geometry ” is an important part of junior high school mathematics. To solve the problem of graphics and geometry, the correct image is often taken as the guide. With the help of the graphic visualization, the complex mathematical problems can be simplified and the image can be explored Solving problems and predicting results can help students to understand math intuitively and play an important role in the whole process of math learning. However, due to limitations of knowledge, experience and methods, students often solve problems of graphics and geometry Make some mistakes by the illusion of visual intuition, now for such typical error classification analysis, find the reasons, and put forward
