传统教学中教师占据着课堂上的大部分时间,“教师讲、学生听”是主要形式,因而教学效率不高。数学本身就比较枯燥、抽象,加之小学生活泼好动,自控能力差,传统教学方法实在激不起学生的学习兴趣,更谈不上创新能力的提高了。随着新课改的逐步深入和科学技术的更新,多媒体渐渐进入了我们的课堂,给数学教学带来了无限生机与活力,让抽象的数学问题变得具体生动,让枯燥的数学问题变得趣味十足,让静止的数学问题变得流动活泼。因此, In traditional teaching, teachers occupy most of the time in the classroom, “teachers say, students listen to” is the main form, so teaching efficiency is not high. Mathematics itself is more boring, abstract, combined with lively primary school students, self-control ability is poor, the traditional teaching methods really can not stimulate students’ interest in learning, let alone improve the ability to innovate. With the gradual deepening of the new curriculum reform and the updating of science and technology, multimedia has gradually entered our classrooms, bringing infinite vitality and vitality to mathematics teaching, making abstract mathematical problems concrete and vivid, making boring mathematical problems become Interesting, so that static mathematical problems become mobile and lively. therefore,
