This paper proposes a learning based method that can automatically determine how likely a student is to give a correct answer to a problem in an intelligent tutoring system. Only log files that record students' actions with the system are used to train the model, therefore the modeling process doesn't require expert knowledge for identifying…

The efficacy of online learning programs is tied to the suitability of the program in relation to the target audience. Based on the dataset that provides information on student enrollment, academic performance, and demographics extracted from a data warehouse of a large Southwest institution, this study explored the factors that could distinguish…

The semantic web or Web 3.0 makes information more meaningful to people by making it more understandable to machines. In this article, the author examines the implications of Web 3.0 for education. The author considers three areas of impact: knowledge construction, personal learning network maintenance, and personal educational administration.…

In this research project, subject terms from the Dewey Decimal Classification (DDC) Schedules and Relative Index were incorporated into an online catalog as searcher's tools for subject access, browsing, and display. Four features of the DDC were employed to help searchers browse for and match their own subject terms with the online catalog's…

This paper presents the background and then reports progress made in the development of two view-based searching systems--HIBROWSE for EMBASE, searching Europe's most important biomedical bibliographic database, and HIBROWSE for EPOQUE, improving access to the European Parliament's Online Query System. The HIBROWSE approach to searching promises…

The Internet has brought about a revolution in the concept of information provision for end-users, and opened up a diverse new market. The Internet has challenged the need for and role of traditional online services. Despite the benefits of the Internet, users face a number of dilemmas: finding needed information in a vast sea of information; time…

The installation of technology in the school library is only the first step in its effective use by students. Many search engines are not intuitively obvious to users, and students often need help with searching. Systematic formal instruction in electronic search skills is necessary for awareness of library software and competence in its use. The…

Electronic publishing has been an agent for change in not just how one publishes but in what one publishes. Describes HyperCite, a joint project with the Institution of Electrical Engineers (IEE) to create INSPEC database. Highlights include the database; the research phase (cross database searching and new interface); and what and how much was…

The Hypermedia Information System (HIS) is being developed under the auspices of the Federal Aviation Administration (FAA) Office of Aviation Medicine's (AAM) Human Factors in Aviation Maintenance (HFAM) research program. The goal of the hypermedia project is to create new tools and methods for aviation-related information storage and retrieval.…

This catalogue from the UCLA Center for Mental Health in Schools provides Internet sites relevant to mental health in schools. The sites are divided into four sections. The first section, "General," contains links to the Center's Web site (http://www.lifesci.ucla.edu/psych/mh/): government (federal, state, local) sites; associations and…

Because experience with large information retrieval (IR) and database management (DBM) systems has shown that they are not adequate for the handling of textual material, two Swedish companies--Paralog and AU-System Network--have joined in a venture to develop a software package which combines features from IR and DMB systems to form a Text Data…

New non-voice services (sometimes also called information services) and the possibilities of telecommunication networks to support them are described in this state-of-the-art review. It begins with a summary of the various data transmission techniques, which include several types of data transmission over the telephone network: general, telegraph…

Describes a simple computer-based information retrieval system which manipulates non-numeric information using a program that simulates a three-level information storage system. The system is used to create, modify, and selectively search a data base both interactively and noninteractively. (MLH)

Introduction: The conceptual framework of librarianship and information science has developed rapidly over the past decade with the prospect of application in other fields. However, transfer of concepts across branches within the field remains problematic and severely limits ability to address important information problems. Requirements: A…

This discussion of the laser videodisk begins by noting that it is an extremely high density visual storage medium that can supply instructors with vast visual warehouses to supplement instruction, whether through conventional group presentations or via individualized computer assisted instruction. Major features of the medium are then described…
