一、创设数学知识与生活实际紧密结合的情景在社会生活中,数学是无处不在的,我们会发现数学,正如《数学课程标准》所指,“数学中,要创设与学生生活环境,知识背景密切相关,又是学生感兴趣的学习情景,让学生在观察、操作、猜测、交流、反思等活动逐步体会数学知识的产生、形成和发展过程。获取积极的情感体验,感受数学的力量,同时掌握必要基础知识和基本技能,将数学知识和学生的生活实际紧密结合起来。”因此这就要求教师在进入课堂之前备好课,备好学生。平时在课余时间教师应做到了解学生的生活和兴趣爱好,课堂引入情境的时候,才能引起学生兴 First, the creation of mathematical knowledge and the actual situation of life closely In mathematics is ubiquitous in social life, we will find that mathematics, as “mathematics curriculum standards” refers to “Mathematics, to create and students living environment, The background of knowledge is closely related to the students’ learning situations, which enable students to gradually understand the process of generating, forming and developing mathematical knowledge in the fields of observation, operation, speculation, exchange and reflection etc. Acquire a positive emotional experience and experience the power of mathematics , At the same time master the necessary basic knowledge and basic skills, the mathematics knowledge and student’s life closely together. ”Therefore, this requires teachers to prepare the class before entering the classroom, prepare students.
