情境是小学数学教学的基本手段和方法。通过直观的场景呈现,让学生进入角色,发挥情感对认知的有效影响作用,能在有限的时间和空间范围内激发学生对原有认知经验的回忆,为数学继续学习做好铺垫,能将生活数学和学校数学进行有机的联姻,促进数学在现实世界中的应用,将生活问题聚敛抽象为数学的模型。情境创设的魅力是无限的,纵观小学数学课堂教学的现状,我们发现,要做到科学严谨地发挥情境对教学的影响,还要直面下列几个基本问题:一、情境的内容和形式一定要是学生感兴趣的案例一:认识钟面教学。多媒体呈现大头儿子和小头爸爸玩跳跳棋的游戏。骰子的六个面上分别标有1、3、5、11、15、21,六个
Situations are the basic means and methods of elementary mathematics teaching. Through the visual scene presentation, students can enter the role and play the role of emotion in cognition. It can stimulate students’ memory of the original cognitive experience within a limited time and space, pave the way for further study of mathematics The life of mathematics and school mathematics organic marriage, to promote the application of mathematics in the real world, the convergence of life problems abstract mathematical model. The charisma created by context is limitless. Looking at the present situation of primary school mathematics classroom teaching, we find that we must face the following basic questions in order to exert the influence of situation on teaching scientifically. First, the content and form of context must be certain Case 1 students are interested: know the clock face teaching. Multimedia presents big head son and head dad playing checkers game.
