随着信息技术的发展,计算机在社会各个领域广泛普及和应用。多媒体技术作为一种有效的辅助教学手段,已被教师们引入课堂教学,它通过文本、图像、声音、动画等方式,创设情境,激发兴趣,进行数学实验,发展了学生的思维,培养了学生的能力,使传统单一的教学模式变得有声有色,大大提高了课堂教学效率,使数学课堂教学具有传统教学不可比拟的优越性。2004年远程教育启动以来,信息技术走进了农村初中课堂,广大教师开始了多媒体教学的实践和探索,取得了一定的成绩,向课堂教学优化和新课程推进迈出了坚实的一步。但在教学实践中多媒体数学教学存在着诸多问题:
With the development of information technology, computers are widely popularized and applied in all fields of society. As an effective auxiliary teaching method, multimedia technology has been introduced into classroom teaching by teachers. It creates situations, stimulates interests, conducts mathematical experiments through texts, images, sounds and animations, develops students’ thinking and cultivates students The ability to make the traditional single mode of teaching becomes very impressive, greatly improving the efficiency of classroom teaching, mathematics classroom teaching with traditional teaching incomparable superiority. Since the start of distance education in 2004, the information technology has entered the rural junior middle school classroom. The majority of teachers started the practice and exploration of multimedia teaching and achieved some success, taking a solid step toward classroom teaching optimization and new curriculum advancement.
