2012年,穿越剧火爆荧屏。剧中的人物会因某个事件忽然从A时空穿越到B时空,可以肆意连接并游走在历史与现实之间。剧中人物在古代文明与现代智慧的碰撞和摩擦中产生的各种冲突吊足了观众的胃口。穿越剧之所以如此受欢迎,我认为是因为以现代视角观察旧时历史,会多了更多的审视、批判、洞明与认同。纵观小学数学课堂教学历史,也发生了翻天覆地的变化。在如火如荼的新课程改革背景下,教师改变了课堂教学只注重知识掌握,重视了三维目标的达成;改变了呈现过程的机械灌输,重视了探索交流;改变了练习形式的陈旧单一,重视了开放性与实践性。
In 2012, through the drama popular screen. The characters in the play will suddenly cross from A to B in time and space because of an event, and may wantonly connect and walk between history and reality. The characters in the play clamored for the appetite of the audience in various conflicts arising from the collision and friction between ancient civilizations and modern wisdom. The reason why the tragedy is so popular is that I think it is because viewing the old history from a modern perspective will have more scrutiny, criticism, insight and identification. Throughout the history of primary school mathematics teaching, earth-shaking changes have taken place. Under the background of the new curriculum reform in full swing, the teacher changed the classroom instruction only to grasp the knowledge, paid attention to the three-dimensional goal, changed the mechanical instillation process, paid more attention to the exploration and communication, changed the old form of the practice and paid more attention to the open Sexuality and practicality.
