空间和图形问题是数学问题当中相对比较抽象的。特别对于一些空间想象能力较差的孩子来说,即使能熟练记住各种图形的计算公式,但还是不能把题目中的文字转化成头脑中的表象,因此不能正确地解决这类问题。下面就以我校的一次三年级教学质量调研中出现的问题,来说说我自己对教学空间图形题的思考。 Spatial and graphical problems are relatively abstract among mathematical problems. Especially for some children with poor spatial imagination, even if they can skillfully remember the formulas of various figures, they still can not translate the words in the title into the mind’s appearance, and thus can not correctly solve such problems. Here to my school a third-year teaching quality research problems that arise, to say my own thinking on the teaching space graphics questions.
