让学生在具体的情境中学习数学,是数学新课标倡导的一种教学理念,也是促进学生自主有效学习的一种重要教学方式,它就好比学生学习的“催化剂”。在小学数学教学中,如何利用各种情境引导学生自主、有效地学习数学?下面笔者结合多年的教学实践,谈几点具体做法。一、利用生活情境促进学生有效学习新课标指出,数学教学要紧密联系学生的生活实际,从学生熟悉的生活环境和感兴趣的事物出发,为他们提供观察、思考的机会。因此,教师应利用学生身边蕴含数学知识 Letting students learn mathematics in concrete situations is a kind of teaching idea advocated by the new curriculum standard of mathematics and also an important teaching method to promote students’ autonomous and effective learning. It is like the “catalyst” for students to learn. In primary school mathematics teaching, how to use various situations to guide students to autonomously and effectively learn mathematics? The author combines years of teaching practice, talk about a few specific practices. First, the use of life situations to promote effective learning of new curriculum standard pointed out that mathematics teaching should be closely linked with the students’ actual life, from the students familiar with the living environment and interesting things, to provide them with the opportunity to observe and think. Therefore, teachers should make use of the mathematical knowledge contained in the students
