一、增加数学教学操作活动,培养数学建模的兴趣小学生生来就有着强烈的探索未知世界的兴趣,这是他们的天性,我们要利用这种天性去唤醒隐藏在学生身上的创新能力,激发出学生进行数学建模的兴趣。因此,在小学数学教学中我们可以增加一些有效的实践操作活动。例如“认识角”一课,对于比较角的大小这一知识点,很多学生认为角的大小与两条边的长短有关,两条边越长角就越大。此时教师可以指导学生利用学具通过动手操作从而构建起真正的数学认识:1.你能把你手中的角变得比老师的这个角大一些吗?2.你还能把你手中的角变得比老师的这个角小一些吗?
First, to increase the mathematics teaching operation activities, to cultivate the interest of mathematical modeling students are born with a strong interest in exploring the unknown world, which is their nature, we want to use this nature to arouse the innovative ability hidden in the students to stimulate Students are interested in mathematical modeling. Therefore, we can add some effective practice activities in elementary mathematics teaching. For example, in the lesson of Cognitive Angle, many students think that the size of an angle is related to the length of two edges, and the longer the two edges, the larger the angle. At this point, teachers can guide students to use hands-on operation to build a real mathematical understanding: 1. Can you make your corner bigger than the teacher’s corner? 2. You can also put your hand corner Is it smaller than the teacher’s corner?
