《义务教育数学课程标准》强调,数学课程应从学生已有生活经验出发,让学生亲历将实际问题抽象成数学模型并进行解释与应用的过程。因此创设具体可感的数学教学情境,不仅能激发学生的学习兴趣,让学生在生活化的数学情境中理解、掌握数学知识,而且可以让学生真切地体验数学情感。一、再现情境,发现问题“生活处处有数学。”学生的生活经历丰富,对生活也有独特的感悟,但他们往往没有把生活与数学联系起来,通过生活实践去发现蕴含其中的数学问题。教材中有许多图文并茂的情境图,它展示
The standard of compulsory education mathematics curriculum emphasizes that the mathematics curriculum should start from the students’ existing life experiences and let the students experience the process of abstracting the practical problems into mathematical models and explaining and applying them. Therefore, to create a concrete and sensible math teaching situation can not only stimulate students’ interest in learning, make students understand and master math knowledge in life-like mathematical situations, but also enable students to truly experience math emotion. First, to reproduce the situation and find the problem “life is full of mathematics. ” Students have rich life experience, have a unique perception of life, but they often do not link life and mathematics, through life practice to discover contains the mathematical problems . There are many illustrations of the situation in the textbook, it shows
