文艺作品中的“伏笔”往往引起故事情节的跌宕起落、妙趣横生,给予读者以悬念,引起读者的深思和探索.数学教学中的“伏笔”同样有着不可忽视的作用. (一)有利于学生明确基本概念. 某些数学概念的引进往往寓意于学生已学过的知识之中.教师在传授那些知识时,要高瞻远瞩,把今天的教学与未来将要教的知识有机地联系起来,精心地组织教学内容.
The “foreshadowing” in the literary and artistic works often causes the ups and downs of the storyline, which gives the reader suspense and arouses the readers’ thoughts and explorations. The “foreshadowing” in mathematics teaching also has a non-negligible role. (1) It is beneficial to the students Basic concepts. The introduction of certain mathematical concepts is often implied in the knowledge that students have already learned. Teachers must be forward-looking in teaching those knowledge. They should organically link today’s teaching with the knowledge to be taught in the future and carefully organize teaching. content.
