论文部分内容阅读
读了《中小学数学》(小学版)2013年第3期顾亚伟的《评价改革,从“学会命题”做起》一文,该文对期末检测卷中的一道试题进行了分析,读后受益匪浅。笔者赞同“评价改革,从学会命题做起”的观点,但文中的这道测试题及顾老师对该题的分析值得商榷,现借贵刊一角与顾老师及各位专家一同探讨。试题:有一块长90厘米、宽70厘米的长方形玻璃。王师傅想用它做一个长50厘米、宽40厘米、高25厘米的无盖金鱼缸,但他不知道这块玻璃够不够?你认为够吗?(请用计算说明)

Master Wang wanted to use it as a capless goldfish tank 50cm long, 40cm wide and 25cm high, but he did not know enough of this glass? Do you think that enough?
