The capabilities of information technology (IT) have advanced precipitously in the last fifty years. Many of these advances have enabled new and beneficial applications of IT in dental education. However, conceptually, IT use in dental schools is only in its infancy. Challenges and opportunities abound for improving how we support clinical care, education,(More)
The goals of this exploratory study were to determine students' assessment of portable digital video instruction (using the Apple iPod) and to compare examination performance among groups of predoctoral dental students who did and did not utilize portable digital video instruction as a supplement to a conventional pediatric behavior management lecture.(More)
This research project was part of a planned initiative at the University of Pittsburgh School of Dental Medicine to incorporate lecture recordings as standard educational support technologies. The goal of an institutional survey was 1) to gather current data about how dental educators across the United States and Canada use lecture recordings; 2) determine(More)
Podcasting has recently emerged as an important information technology tool for health professionals and consumers around the world. Prestigious journals, international conferences, universities and government agencies among other entities are starting to publish digital informotion via audio and video podcasts. Podcosting is distinguished from other forms(More)
The Federal COBOL Compiler Testing Service (FCCTS) was transferred from the Department of the Navy to the General Services Administration (GSA) in May, 1979. GSA renamed it the Federal Compiler Testing Center (FCTC) and expanded its functions beyond that of COBOL compiler validation. This paper discusses (1) the effect of the FCCTS/FCTC in the area of COBOL(More)
Competitive computer system selection requires a tool for minimum performance measurement. The selection process must be fair and, ideally, brief and economical. Thus, the measurement tool must be visibly fair and impartial in its measurement of a computer system, it must relate what is being measured to user needs, and it must be economical to apply. The(More)
The acquisition of major Automatic Data Processing Equipment (ADPE) systems in the Department of the Navy is accomplished by either single source acquisition or competitive selection. In the case of the single source acquisition, only one vendor is considered as having the system capable of satisfying the needs of the procuring organization. The criteria(More)
To be an effective assessment tool, a simulation-based examination must be able to evoke and interpret observable evidence about targeted knowledge, strategies, and skills in a manner that is logical and defensible. Dental Interactive Simulations Corporation's first assessment effort is the development of a scoring algorithm for a simulation-based dental(More)
PURPOSE Computer programs have been developed for removable partial denture (RPD) design, but their educational impact has never been investigated. This study measured the effectiveness of computer-based RPD design simulations in a traditional RPD design course for second-year dental students. MATERIALS AND METHODS Thirty-six students were randomly(More)
Continuing dental education (CDE) courses delivered on the World Wide Web (Web CDE) offer numerous advantages over traditional CDE; however, two major issues--location of suitable courses and course quality--need resolution. Locating high-quality courses is difficult due to the lack of the standardized metadata that allows search engines to match courses to(More)
