数学与生活密不可分,生活离不开数学,数学更离不开生活。离开了生活的数学只能成为无源之水、无本之木。《义务教育数学课程标准》也明确指出:“数学是生活的一部分,是人们生活、劳动和学习不可缺少的工具。”因此,数学教学不仅要考虑数学自身的特点,更应从学生的已有生活经验出发,将教学活动置于真实的生活背景之中,达到数学教学生活化,从而达到理想的教学效果。从教材内容生活化,促使学生主动参与学习;让学生感受到所学知识来源于生活;让学生在实践中体验数学知识的应用三个方面,谈谈在数学教学中如何创设有意义的生活情境,为学生提供接触生活、感受生活的机会,使他们有更多的机会从周围熟悉的事物中学习和理解数学,体会到数学就在身边,从而更能发挥学生学习的主体性。
Mathematics and life are inseparable, life can not be separated from mathematics, mathematics can not do without life. The mathematics that have left life can only become the passive water and the wood without roots. The “Mathematics Curriculum Standard for Compulsory Education” also clearly states: “Mathematics is a part of life and it is an indispensable tool for people’s life, labor, and learning.” Therefore, mathematics teaching must not only consider the characteristics of mathematics itself, but should also be based on students’ knowledge. Starting from life experience, the teaching activities are placed in the real life background to achieve the mathematics teaching life, so as to achieve the ideal teaching effect. From the life of the teaching materials, students are actively involved in learning; students are allowed to experience the knowledge they have learned from life; students are allowed to experience the application of mathematics knowledge in practice; and they talk about how to create meaningful life situations in mathematics teaching. It provides students with the opportunity to come into contact with life and experience life, so that they have more opportunities to learn and understand mathematics from the familiar things around them, and realize that mathematics is on the side, so as to better exert the subjectivity of students’ learning.
