广州拓创第一部分技 术 方 案广州拓创前言随着我国多媒体水平不断提高,大部分学校都已引进各种多媒体教学设备或建成了多功能、综合性的多媒体控制系统。如何配置多媒体综合电教室,配备哪些设置才能既达到使用方便,功能齐全,投资少,又能提高教学质量的目的,是目前多媒体功能电教室所急需解决的问题。一、校园概况及用户需求:某中学是*市最为重要的高级中学培养人才基地之一,随着二十一世纪的到来,学校在大力度发展经济的同时,为贯彻中央“科教兴国”的方针,在学校建设方面更是加大了在人力、物力、财力方面的投入,为迎接二十一世纪知识经济的挑战的来临做好充分的准备。一直以来学校教学都沿用传统的黑板加粉笔的教学模式,方式落后,形式死板,无法满足现在多元化形象教学的要求,因此,为普遍提高学校的教学质量,在新形势和新要求下,推进高新科技在教育教学领域的应用已事在必行,而电化教学是高新技术在教育领域里的直接体现。参照国内外学校的先进教学经验,结合自身的实际情况,安装电教设备,全面提高教师和学生运用电教设备进行学习和工作的能力,创造适应时代要求的新的教学模式、评价模式和管理模式,同时提高工作效率和管理水平。文档编码:CG9B5O4H9V10

简单、实用、经济、实惠三、系统简介多媒体电教室是多种系统的有机结合,它主要是由以下几大部分组成:(一)、大屏幕投影系统大屏幕投影系统从安装方式上可分为前投式和背投式两种类型。前投式系统价格较低,安装方便,且其画面效果不易受环境光影响,是多媒体电教室采用较普遍的投影方式;背投式系统画面均匀度较好,画面质量较高,但易受环境光影响(室内光线须作一定的控制)。而且其安装受空间限制,安装难度较大,价格也较高。大屏幕投影系统从工作原理上主要分为三类:CRT三枪投影机、LCD液晶投影机和 DLP数字投影机。LCD液晶投影机亮度高,操作简便,成像效果好且价格较便宜,因此是现在市场上的主流产品,市场份额达到70%以上。结合天河区党校实际情况我方建议使用亮度较高的(2000ANSI以上)液晶投影机较为适合。(二)、中央控制系统多媒体电教室内各种音频、视频设备较多,整体操作比较困难。为此,我们推荐配备中央控制系统对设备进行集中控制。文档编码:CG9B5O4H9V10 HC7K8S1F9I9
