E-learning systems are used by many universities for both blended learning and distance education. In both cases the success of courses depends, among many other factors, on e-learning applications that work reliably. For e-assessments the expected level of reliability and dependability is even higher. By clearly analyzing technical and…

A traditional distance learning system requires supervisors or teachers always available on online to facilitate and monitor a learner's progress by answering questions and guiding users. We presents an English chat room system in which students discuss course contents and ask questions to and receive from teachers and other students. The…

Electronic reference resources are expanding traditional print reference collections far beyond the walls of the library building. While the library literature has seen a debate rage about the various merits and pitfalls of electronic reference sources, no one disputes they are here to stay.

The national science standards, along with prominent researchers, call for increased focus on scientific argumentation in the classroom. Over the past decade, researchers have developed sophisticated online science learning environments to support these opportunities for scientific argumentation. Assessing the quality of dialogic argumentation,…

There is growing interest in the use of virtual gaming worlds in education, supported by the increased use of multi-user virtual environments (MUVEs) and massively multi-player online role-playing games (MMORPGs) for collaborative learning. However, this paper argues that collaborative gaming worlds have been in use much longer and are much wider…

Describes a clustering algorithm designed for dynamic data bases and presents an update procedure which maintains an effective document classification without reclustering. The effectiveness of the algorithms is demonstrated for a subset of the Cranfield collection. (Author)

Intended for the experienced TUTOR author who needs a quick reference for the form of a tag and for some of the restrictions on commands, this summary does not discuss the fine details of the TUTOR language. Brief descriptions of the purpose and the tag are provided for each command. The commands are grouped in nine categories: calculating (C),…

Intended to teach the principles of interactive bibliographic searching to those with little or no prior experience, this textbook explains the basic elements of online information retrieval and compares the major database search systems. Its chapters address (1) relevant definitions and vocabulary; (2) the conceptual facets of database searching,…

Three aspects of training and education for online searching of bibliographic and databases are addressed: (1) the present status--what is being taught, (2) a proposed model--what needs to be taught, and (3) the implementation of the model--who should teach what. The first section shows which organizations (library and information schools,…
