建构主义理论指导下网络课程的设计原则

当前我国大部分网络课程的设计仍以行为主义的制激－－反应理论指导思想，还存在着种种不足。由于建构主义理论所要求的学习环境得到当代最新信息技术成果的强有力的支持，因此，应建构主义理论指导下进行网络课程的设计，网络课程设计的原则有：主动性原则，指导性原则，协作性原则，情景性原则。     

论分卷考试考务管理与考生答题要求

随着计算机科学和网络技术的发展,我国的各类考试方式也发生了很大改变,大部分考试已从过去的常规卷改成了分卷形式。阅卷也逐步从纸质改为机器阅卷和网上评卷。网上评卷为多评制创造了条件,对考试管理和考生答题提出了新要求。本文以全国大学英语四六级考试为例,对实施网上评卷,扫描答题卡过程中发现的一些问题,提出自已的看法和建议,以促进分卷考试更适应机器阅卷和网上评卷工作的要求。

The Delphi Project: Transforming Flemish Libraries Into User-Oriented Points of Information

ABSTRACT

Flemish libraries have historically been praised by visitors and valued by the general public, but since the turn of the century, they have seen a decline in usage. A group of libraries in Flanders believed the role of libraries should be substantially reevaluated. They embarked on the “Delphi Project” to establish methods for libraries to become centers of their local communities by focusing on the information needs of their customers. The emergence of technology supported a shift from libraries as lending institutions to information centers. In addition to a customer service philosophy and training, online tools have helped staff reach library users. An online tool called the “Bronnenwijizer” combines searching the local library catalogue, provincial and state catalogues, and the Internet. The tool also supports the creation of “baskets” for a patron's information needs that can be shared with other staff. Delphi libraries have also used “Infopleinen,” Web-based guides to topics featuring printed media and online sources. Finally, a new online question registration system was developed that fit the new Delphi service philosophy. Over half the libraries in West-Vlaanderen are entitled to call themselves Delphi Libraries, and the philosophy is being disseminated more broadly through the Delphi Project Web site. Due to governmental changes in provincial authority, the future of the project is challenged because coordination among libraries has been critical for the project's success.
