从教十五年来,我经常探索:如何提高小学生解应用题的能力?根据这些年的探索,谈几点做法。一、将抽象的数学知识生活化,激发学生的学习兴趣创设一个良好的教学情境,能够激发学生学习的兴趣,这样,他们解决问题的能力就提高了。例如,我教学《圆的周长》时,把课本上的情境图,改成了大小不同的圆形的钟表和北湖上摩天轮这两种学生熟悉的物体的图片,学生的学习兴趣高涨,很轻松地推导出了“圆的周长=圆周率×直径”。
From teaching for fifteen years, I often explore: how to improve the ability of primary school students to solve the problem? According to these years of exploration, to talk a few practices. First, to abstract the mathematical knowledge of life, to stimulate student interest in learning to create a good teaching situation, can stimulate students interest in learning, so that their ability to solve the problem improved. For example, when I was teaching “Circumference of the Circles,” I changed the picture of a situation on a textbook into pictures of objects familiar to students of two different sizes, round watches and Ferris wheel at North Lake. As students’ interest in learning soared, It is easy to deduce “circle circumference = circle rate × diameter”.
