数学教学要与现实生活相联系,这是新课程改革的一个重要特点。一方面新课程倡导用具体的、有趣味的、富有挑战性的素材引导学生投入数学活动;另一方面强调学生主动地运用数学知识解决问题,用数学眼光从生活中捕捉数学问题。也就是说,新课程不仅注意数学知识的生活化,同时也注意生活问题的数学化。所以,教师应充分考虑学生原有的生活经验、认知水平来创造生活情境,使学生体验数学就在身边,生活中处处有数学;在课堂中营造生活氛围,使学生置身于生活之中;从学生感知的生活经验出发,引导学生用数学知识解决生活中的问题,凸现数学知识的应用价值。
Mathematics teaching should be linked with real life, which is an important feature of the new curriculum reform. On the one hand, the new curriculum encourages students to engage in mathematical activities with specific, interesting and challenging materials; on the other hand, students emphasize that students take the initiative to solve problems by using mathematical knowledge and mathematics problems to capture mathematics from the perspective of life. In other words, the new curriculum not only pay attention to the life of mathematical knowledge, but also pay attention to the mathematical problems of life. Therefore, teachers should give full consideration to students’ original life experience and cognition level to create a living situation, enable students to experience mathematics at their side, and have maths everywhere in their life; to create a living atmosphere in the classroom so that students may be exposed to life; Starting from the students’ perceived life experience, the students are guided to solve the problems in their daily life by using mathematical knowledge, which shows the application value of mathematical knowledge.
