“让学生在生动具体的情境中学习数学”是小学数学新课标的一个重要理念之一。在这种理念下,传统的数学教材也作了相应的改变,由“例题+习题”模式转变为“创设情境—建立模型—解释应用”模式。当前,现代教育技术的发展对数学教学的价值、目标、内容以及教与学的方法产生了重大影响。越来越多的教师在数学情境创设方面使用多媒 “Let students learn mathematics in a vivid concrete situation ” is one of the important concepts of the new curriculum of elementary mathematics. Under this concept, the traditional mathematics teaching materials have also been changed correspondingly, from “Example + Exercises ” mode to “Create situation - Establish model - Explain the application ” mode. At present, the development of modern educational technology has a significant impact on the value of mathematics teaching, goals, content and teaching and learning methods. More and more teachers use multimedia in the creation of mathematical situations
