1、在传统的教学方式中,师生每天在教室里面对面地上课、提问和答疑;课后学生做完作业,等着教师的批改结果;考试场上,教师一刻不停地监考,学生紧张地答卷等。这种体制下出现的各种不良结果,常见的有学生厌学情绪严重、抄袭别人作业、考试作弊,更有甚者直至荒废学业。2如何克服传统教学弊端,提高教师学生工作学习的效率,降低教师的工作压力,减轻学生的学业负担,提高学生的学习积极性,同时熟悉计算机操作,发挥计算机和Internet 网络在教学工作中的作用,是本论文主题探索研究的方向。现在一些运行的教学系统,要么是采用基于局域网的C/S结构的平台,要么是采用ASP技术开发的网络教学系统。本论文选择JSP+SQLSer
2、ver搭建网络教学系统平台,它们是当今世界最前沿最流行的两种网络开发技术的黄金搭配组合。JSP技术日趋稳定成熟,它拥有卓越的系统可移植性,同时它与流行的XML等技术也能良好整合,加上SQLServer2000数据库强大的后台数据支持,奠定了JSP技术在网络应用系统开发中的关键地位。3这次的毕业设计开发了计算机科学与工程学院远程教学系统V1.0。这种平台不仅满足了传统教学的基本要求,并且充分运用了计算机和网络技术,有效弥补了现行教学方式的不足,学生选课后,实行教师上传学生下载的学习过程同时还可以相互留言实行互动环节。随着教学系统的应用、更新和完善,平台将给学校教学工作注入新的活力,并且有效地促进

14、尤其在开放的和远程的教学方面。网络教学是利用计算机网络技术、多媒体技术等现代信息技术手段开展起来的一种新型教学形式。它使得广大受教育者可突破传统教育在教育资源(师资、教材、实验和演示设备等)和教育方法(统一进度、集中式和单向传授等)方面的限制,实现优秀教育资源和教育方法不受时间和空间等约束的共享。9网络教学可以实现优秀教育资源和教育方法不受时间和空间等约束的共享,受教育者根据自己的水平和时间情况安排自己的学习计划和学习进度,实现传统教育无法做到的“个性化教育”。1612国内外研究现状 目前,它的研究和应用主要有两种形式:一种是基于Web的软件实现方式,在这种方式下,学生或教师只要有一台连网的计
15、算机,就可以通过软件进行远距离教学,不需要特殊的硬件,在这样的系统中学生可以进行学习、讨论、考试等,学生和教师之间可以传输文字、图形、声音、图像等各种信息;第二种形式是基于视频会议系统的实现方式,它除了需要第一种方式中的各种软件支持以外,还需要特殊的硬件,使学生和教师可以相互实时看到和听到对方,同时也可以充分利用视频会议系统所提供的特殊功能。8今年来为规范远程教育的教学内容,国家建设了大批的精品课程,取得了巨大成绩,每年增添精品课程数百门,但这些课程在智能理论及应用方面的探索仍留有不少发展空间,精品课程下一个阶段将是朝向智能化方向发展。远程教学从研究以个别化学习为主的自主学习和适应性学习,到以小组为主的协作学习与合作学习,以及今天人们更为关注的多元智能理论和混合型学习,其中任何一种学习方式的引用均对教育和远程教育的发展起着不同的推动作用。目前远程教学具体内容可以归结为以下几个层面:1. 开始关注合作学习 主要是基于数据仓库支持合作学习的智能教学专家系统。2. 评价测试方面通过分析学科材料和测检结果提供学习意见的概念图模型3. 国内外的实例系统目前国内外的实例系统有:Intermodel系统;系统等。上述系统的总体优点是具有why和how解释机制;存在的问题及不足在于:1)只有选择性答案
