著名数学家华罗庚说:“人们对数学枯燥无味、神秘难懂的印象,原因之一便是脱离实际。”必须承认,以往我们的教学内容确实存在脱离学生生活实际的现象,加之一些教师创新意识不强,偏重书本知识,不善于挖掘生活中的数学素材,这就大大影响了学生学习数学的兴趣和效果。为此,我们亟待打破教材的局限,走出观念的误区。新课程标准就更多地强调了学生用数学的眼光从生活中捕捉数学问题,主动地运用数学知识分析生活现象,自主地解决生活中 Huarong Geng, a famous mathematician, said: “One of the reasons people are impolite and mysterious is that they are out of touch with reality.” "We must admit that in the past our teaching did exist from the actual situation of student life. In addition, some teachers’ innovations Consciousness is not strong, emphasis on book knowledge, not good at mining mathematics material in life, which greatly affected the students interest in learning mathematics and effectiveness. For this reason, we urgently need to break the limitations of teaching materials and get rid of the misunderstanding of concepts. The new curriculum standard places more emphasis on students using mathematics to capture mathematical problems in life, take the initiative to use mathematical knowledge to analyze the phenomenon of life, autonomously solve life
