Synopsis

This book presents the challenges & dilemmas faced by leading researchers as they created their new computerized assessments. It examines the potential for computerized assessment in the fields of psychometrics, I/O psychology, & educational measurement.

Excerpt

It is hard to believe how much computer technology has changed since we started to develop our interactive video assessment in 1989. At the time we were barely able to purchase what was the state-of-the-art in interactive video: a laser disc player, a full-motion video adaptor, and a personal computer with a 16 MHz microprocessor. To reduce development time, we produced a prototype of the video clips for our assessment while we simultaneously developed software and grappled with the psychometric and theoretical issues underlying the assessment.

In 1991, we presented a symposium on our project at the Society for Industrial and Organizational Psychology conference in St. Louis. We hauled bulky equipment and prototype materials to the conference so we could demonstrate the technology. Our symposium was at 8:00 a.m., so we were there early to connect our equipment to the video projection system. We held our breath, crossed our fingers, and prayed to the computer assessment gods that it would work. Our equipment worked, but the projection system was able to display only 16 colors at a rate much less than 30 frames per second. It was too late to change, so we gave our presentations and explained our research. When it was time to demonstrate the prototype, we first apologized for the poor quality of the projection and started the interactive video assessment. There was an audible gasp from the audience; most had not previously seen full-motion video presented on a personal computer. Today, just 8 years later, video presented by computer is commonplace.
