数学家华罗庚说过:“宇宙之大,粒子之微,火箭之速,化工之巧,地球之变,日用之繁,无处不用数学。”数学与生活的密切联系决定了在数学教学中,教师必须让学生深切体会到数学的实用性这一特点,进而从目的出发,培养兴趣,学习数学思考方法运用于实践。虽然也在平时的教学中一再强调数学与生活的联系,在知识的呈现方面也体现一个生活化特点,但效果一直都不是很明显,学生把数学仅仅作为一门功课,一项任务来完成的想法根深蒂固,很少能自主地把所学知识运用于生活实践。
Mathematician Hualang Geng said: “The universe, the micro-particles, the rocket speed, the cleverness of the earth, the change of the earth, the complex of daily use, mathematics everywhere.” Mathematics and life is closely linked to determine the mathematical Teaching, teachers must enable students to fully appreciate the practicality of this feature of mathematics, and then starting from the purpose, to develop interest in learning mathematical thinking methods used in practice. Although it also emphasizes the connection between mathematics and life repeatedly in ordinary teaching, it also shows a life-changing characteristic in the presentation of knowledge. However, the effect has not always been obvious. Students take mathematics as a homework and a task Deep-rooted ideas rarely apply what they have learned to life practice.
