心理学家研究表明,通过语言形式从听觉获得的知识能记忆15%,从视觉获得的知识能记忆25%,利用声光同步,把视觉和听觉结合起来能够记忆的内容可达65%。在小学语文课本中,有许多生动的人、物、事,仅凭教师的语言介绍和分析往往是抽象的,运用多媒体技术可提供形象、生动的参照物,诱导学生多角度、多方位观察和思考,激发学生兴趣。但是,多媒体作为一种教学媒介和方法,会因自身技术形式和教师运用方式的不足给教学带来一定影响,需合理运用,趋利去弊,充分发挥其在教学中的积极作用。
Psychologist studies show that 15% of the knowledge gained from hearing through speech can be memorized, 25% of knowledge gained from vision can be memorized, and up to 65% can be memorized using a combination of sight and hearing using sound and light.

The use of multimedia technology can provide images and vivid reference materials to induce students to observe from multiple perspectives and directions Think, stimulate student interest. However, as a kind of teaching medium and method, multimedia will exert some influence on teaching due to its own technical forms and inadequate ways of teachers’ utilization. It is necessary to make rational use of the media and benefit from the disadvantages to give full play to its positive role in teaching.
