后台操作、管理技术构建网络课件的优点与实现技术——以土壤资源调查与评价网络课件为例

大学生核心课程"土壤资源调查与评价"内容多、应用技术多,讲授内容需随时加以更新,并且该课程需要的教学环节多,有课堂讲授,在实验室进行的实验,还有野外教学实习,因此创建该课程基于网络课件的教学模式很有必要。本文采用ASP动态网页技术进行了"土壤资源调查与评价"课程网络课件的开发与管理。此网络后台可以支持整个网络课件正常、高效、高度安全的运行,也便于管理者(教师)对课件进行日常管理和信息维护与发布。运用后台系统管理的方法构建网络课件,可以使网络课件更有生命力。ASP动态网页技术具有占用系统资源少、信息量大、便于课件维护、扩充和更新、易于继承和保护历史数据的优点,构建的网络课件可以实现在建立前台信息发布的同时,还建立有一套具有友好用户界面的后台管理维护系统。

Advantage and Development of the Net-courseware by the Backstage Operation and Management Techniques

The course of Soil Resource Investigation and Evaluation is necessary to renew the teaching content constantly,but it demands a series of teaching procedures including classroom lectures,experiments in the laboratory,and a teaching practice to do an entire soil survey and mapping.Therefore,it is important to establish a net-courseware for students to study by themselves.The net-courseware was established by adopting the technique of the ASP dynamic state web page technique.The net backstage of the courseware can support the normal,efficient,and high safety implements of the whole net-courseware,and it allows managers(teachers) to carry on the usual management,the maintains and release of information of the courseware easily.The ASP technique has advantages such as little system resources,great information capacity,and convenience in sticking up the courseware,enlargement and renewal.
