论现代教学中的多媒体使用

On the Application of Multimedia Technology in the Modern Teaching

现代教学具有主体性、民主性、多样性与开放性的特点。多媒体的特性使其与现代教学之间表现出高度契合。多媒体所发出的刺激更易引起学生的注意,它所渲染的氛围更易唤醒学生的情绪体验。教师借助多媒体构建起的"准真实情境"有助于学习者对学习内容的感受、理解和记忆。而且,多媒体还能为学生提供高水平的示范。多媒体教学优势的发挥需要遵循一定的原则。教师在具体使用时既要注意使用的契机、方式,控制使用的频次和多媒体的信息负载总量,还要注意适时地设疑激思、因势利导,启发学生去想象、体悟和思考,以克服多媒体潜藏的弊端,从而最大限度地促进学生的全面发展。
