“大”字和“小”字在福建路小学一年级教室里,李忠敏老师在教学“大”字和“小”字。老师拿出两块大小不同的黑板,问道:“同学们,你们比一比这两块黑板哪块大,哪块小?”同学们经过分析比较回答了老师的问题。这时老师放下手中比较小的黑板,举起那块比较大的黑板,又问:“同学们,这块黑板和教室里墙上的黑板比,哪块大?”学生回答:“墙上的黑板大!”老师说:“对!只有比一比,才知道大和小!”大和小是相对的,有分析,有比较,才能有鉴别,这是既简单又深刻的辩证法原理,而教师讲得是何等通俗易懂呀! “Big” and “Little” characters In the first grade classroom of Fujian Road Primary School, Teacher Li Zhongmin is teaching “Big” and “Small” characters.
