摘要
随着教育改革的不断深入,推进素质教育,最大限度地提高课堂效率,减轻学生负担,成为摆在我们每一个教育工作者面前的重要问题。要减轻学生负担,首先要提高课堂效率。研究资料表明:同一时间内,人们从听觉获得的知识只能掌握百分之十五,从视觉获得的知识只能掌握百分之二十五,而视听结合接受的知识则能掌握百分之六十五。因此要合理的运用多媒体教学,通过多媒体生动、形象的音、形、色把记录语言的符号变为生动逼真的画面和富有感染力的声音一一再现出来,让学生通过视觉、听觉等感官直接感知具体的教学内容,调动他们的思维,激发他们的想象。这样多媒体教学将音乐、美术、语文等各学科集于一身,同时作用于人们的多种感官,有利于调动学生的积极性和主动性,让学生乐于动脑、动口、动手探究新知,同时也可以改变以往的枯燥单一的只是依靠板书和重复讲解造成的高耗低效课堂——时间无效浪费、学生课堂练习少,无实践无操作,课后作业重,无效果。
With the deepening of education reform,promotion of quality education to maximize classroom efficiency,reduce the burden on students placed in front of each of our educators.To reduce the burden on students,we must first improve the efficiency of classroom.Research data show that：the same time,the knowledge gained by people from the hearing can only grasp by 15 per cent,can only grasp 25% of the knowledge gained from the visual,audio-visual combination of accepted knowledge can grasp by Sixty-five.Therefore reasonable use of the multimedia teaching,record the language of symbols into vivid images and powerful voice-reproduced by the multimedia vivid image of the sound,shape,color,students directly through visual,auditory and other sensory perception of the teaching content,and mobilize their thinking,to stimulate their imagination.So that multimedia teaching various disciplines,including music,art,language,etc.rolled into one,while the role of a variety of senses,arouse the students＇ enthusiasm and initiative,and students to enjoy their brains,tongue,hands-on exploring new knowledge,but also can change the boring single just rely on the blackboard and repeat to explain the high consumption and low efficiency class-invalid time to waste students＇ classroom practice,no practice and no operation,heavy homework,no effect.
