数学具有高度的抽象性、严密的逻辑性和广泛的应用性。很多学生对此学科的学习兴趣淡薄。电教媒体给我们的数学课堂带来了新的生机、注入了新的活力。运用电教媒体创设情境能激发学习兴趣、能巧妙设疑鼓励自主探究、能转化构建空间观念、能梳理关系提高解题能力、能突破难点加强思维训练,给学生一双带“电”的翅膀,让学生畅游数学知识的海洋,真正“网”住课堂精彩。本文将结合自己的课堂教学实践,谈谈运用电教媒体优化数学课堂教学的策略。一、运用电教媒体,巧妙设疑鼓励自主探究 Mathematics has a high degree of abstraction, strict logic and a wide range of applicability. Many students have a weak interest in the learning of this subject. Audio-visual media brings new life to our math class and breathes new life into it. The use of audio-visual media to create situations can stimulate interest in learning, can be cleverly suspicious of questions to encourage independent inquiry, can transform the concept of building space, to comb the relationship to improve the ability to solve problems, can break through the difficulties and strengthen thinking training, to give students a pair of “electric” wings , Let students swim math knowledge of the ocean, truly “net ” living classroom wonderful. This article will combine my own classroom teaching practice, talk about the use of audio-visual media to optimize mathematics classroom teaching strategy. First, the use of audio-visual media, cleverly designed to encourage independent inquiry
