中美小学数学课程“图形的认识”的比较研究

美国小学几何的图形的认识内容丰富,重视对探究、猜想、推理能力的培养。我国现行的数学课程小学几何的图形的认识的内容和要求,与大纲相比基本不变。与美国相比,我们的内容比较狭窄,有一定的拓展空间。建议增加一些几何图形的概念,如点、中点、平面、相交线、平面图形、多边形、立体图形等,以培养学生的空间观念、探究能力和创新精神。

Comparison of Primary Geometric Figures between China and USA

The contents of American primary geometric figures are rich,which focuses on the ability to explore,guess and reason.The contents of Chinese primary geometric figures in the mathematics curriculum,however,are almost the same as stipulated in the syllabus.Compared with those of America,the contents of Chinese primary geometric figures are relatively narrow,and have certain room for improvement.The paper gives some suggestions for modifying the contents of Chinese primary geometric figures so as to cultivate ...
