The use of computers as teaching and learning tools plays a particularly important role in modern society. Within this scenario, Brazil launched its own version of the "One Laptop per Child" (OLPC) program, and this initiative, termed PROUCA, has already distributed hundreds of low-cost laptops for educational purposes in many Brazilian…

Recognizing that undergraduate students can benefit from analysis of 3D protein structure and function, we have developed a multiweek, inquiry-based molecular visualization project for Biochemistry I students. This project uses a virtual model of cyclooxygenase-1 (COX-1) to guide students through multiple levels of protein structure analysis. The…

The Internet Age has seen the emergence of richly annotated image data collections numbering in the billions of items. This work makes contributions in three primary areas which aid the management of this data: image representation, efficient retrieval, and annotation based on content and metadata. The contributions are as follows. First,…

Purpose: The purpose of this investigation was to conduct an evidence-based systematic review (EBSR) of peer-reviewed articles from the last 30 years about the effect of different service delivery models on speech-language intervention outcomes for elementary school-age students. Method: A computer search of electronic databases was conducted to…

Shared databases are used for knowledge exchange in groups. Whether a person is willing to contribute knowledge to a shared database presents a social dilemma: Each group member saves time and energy by not contributing any information to the database and by using the database only to retrieve information which was contributed by others. But if…

The University of North Carolina School of Medicine developed a computer database, INQUIRER, containing scientific information in bacteriology, and then integrated the database into routine educational activities for first-year medical students in their microbiology course. (Author/MLW)

Examines a nonintrusive model for technology training in teacher education and describes the University of Northern Iowa's basic preservice technology training course: educational media and classroom computing. Discusses media production, distance education, hypermedia, e-mail, telecommunications and the Internet, database construction,…

This pamphlet presents brief reviews of 38 population education software and online systems currently available. It includes mathematical models, simulations, databases, problem-solving games, online systems, and associations. The review includes a description of the program, the level at which it is aimed, required computer hardware, the vendor's…

Proposes a Web-based model as the infrastructure to store learning logs for analysis in distance education. Describes the method of using query language to retrieve information from a database to construct the data cube. Illustrates data-cube implementation with a group-discussion example. Shows how data-cube technology can solve the recording and…

The goal of the Carnegie Mellon Online project is to build an infrastructure for delivery of courses via the World Wide Web. The project aims to deliver educational content and to assess student competency in support of courses across the Carnegie Mellon University (Pennsylvania) curriculum and beyond, thereby providing an asynchronous,…

A study was initiated to investigate the current status of technology initiatives in terms of their impact on six adult education centers in Massachusetts. It was designed to provide new insights into the educational effects of computer instruction upon adult basic education students. A second effort focused on the presentation of a model of…

The Occupational Articulation Project at Lane Community College (LCC) is designed to enhance vocational curricula and encourage articulation by involving business and industry in the development of 2+2 curricula for secondary and postsecondary institutions. Business and industry representatives develop comprehensive lists of the skills needed and…

This paper describes the process used to design and evaluate a computer-based tool that guides the development of lesson plans. The tool, PLANalyst, contains a small expert system with a human face that analyzes lessons and gives specific feedback for improvement. The process used to create PLANalyst can be generalized to the development of tools…

This paper discusses the changing role of teachers and students working on the World Wide Web and outlines the following eight characteristics and associated descriptors of the engaged learning model: (1) vision of learning (responsible, strategic, energized, collaborative); (2) tasks (authentic, challenging, multidisciplinary); (3) assessment…

This document reports on the content model of the Occupational Information Network (O*NET), which is intended to replace the "Dictionary of Occupational Titles." The following chapters are included: "Introduction" (Michael D. Mumford and Norman G. Peterson); "Content Model" (Michael D. Mumford and Norman G. Peterson);…
