Examines various types of link list structures built on top of the traditional random access files for application to a database query technique involving multiple keys, and shows how the technique can improve performance of traditional random access files for the Grants Information System. (Author/CMV)

An innovative concept of an electronic learning system has been established in an attempt to achieve a technology that provides engineering students with an instructive and affordable framework for learning engineering-related courses. This system utilizes an existing Computational Fluid Dynamics (CFD) package, Active Server Pages programming,…

Web-based education and training provides a new paradigm for imparting knowledge; students can access the learning material anytime by operating remotely from any location. Web3D open standards, such as X3D and VRML, support Web-based delivery of Educational Virtual Environments (EVEs). EVEs have a great potential for learning and training…

Describes design of three linked databases on gardening which are intended for use by home computer owners. Principles of development of these programs--which are neither expert systems nor databases in the usual sense--are outlined, and the self-education process in which the developers found themselves engaged is discussed. (MBR)

Describes the computer management system used in teaching a self-paced elementary algebra course at the University of Tennessee at Chattanooga including the hardware, database, principal management program, and some report generation using an inquiry language. The source code of the management program is appended. (Author/CMV)

Describes an APL implementation of a relational database system suitable for use in a teaching environment in which database development and database administration are studied, and discusses the functions of the user and the database administrator. An appendix illustrating system operation and an eight-item reference list are attached. (Author/JL)

Discussion of computer-based testing (CBT) focuses on the development of the database format question (DFQ) which allows the user to build up a more complex answer than multiple choice by selecting items from a database presented on the computer screen. Programing is explained and an evaluation of DFQ is included. (Seven references) (LRW)

We report on the use of email lists as a supplement to teaching. We argue that email lists can provide a valuable students-instructor communication channel and describe the process of setting up and managing such lists. A case study of email messages exchanged in an introductory operations research course is also included. The case illustrates how…

Describes the development of a financial computing laboratory at the University of Lancaster (United Kingdom) and outlines the ways in which online financial information has been integrated into teaching and research. Highlights include hardware used; computer networks; commercial databases used in the financial sector; and teaching and research…

Describes a computer-assisted testing system which produces multiple-choice examinations for a college course in business administration. The system uses SPIRES (Stanford Public Information REtrieval System) to manage a database of questions and related data, mark-sense cards for machine grading tests, and ACL (6) (Audit Command Language) to…

Whereas existing learning environments on the Web lack high level interactivity, we have developed a human tutor-like tutorial conversation system for the Web that enhances educational courseware through mixed-initiative dialog with natural language processing. The conversational tutoring agent is composed of an animated tutor, a Latent Semantic…

Describes a microcomputer-based examination system based on multiple choice questions (MCQ) that has been used for the assessment of aptitude in chemistry. The ability of the system to generate a test based on a student's previous performance is explained, and the system design and implementation are detailed. (eight references) (Author/LRW)
