Developing Data Systems To Support the Analysis and Development of Large-Scale, On-Line Assessment.
Yu, Chong Ho
Today many data warehousing systems are data rich, but information poor. Extracting useful information from an ocean of data to support administrative, policy, and instructional decisions becomes a major challenge to both database designers and measurement specialists. This paper focuses on the development of a data processing system that integrates multiple types of analyses to support the maintenance and further development of a large-scale online assessment efficiently. An automation package has been developed that involves three components of data processing using a Perl script as the master program: (1) data parsing through Perl; (2) data analysis with Iteman, Winsteps, Bilog/Bilog MG, LISREL, and the Statistical Analysis System (SAS); (3) data presentation through Xlisp-Stat/DataDesk, Web page generation. With this online and automated system, content experts could examine the psychometric attributes of test items in a more efficient manner. (Contains 6 figures and 12 references.) (Author/SLD)
