Analysis of daily student usage of an educational multimedia system

This paper presents an analysis of user logfiles from the Analog VideoJockey (AVJ) and the Digital VideoJockey (DVJ) Systems at Purdue University. The AVJ system is a digitally-controlled, analog video educational multimedia delivery system that serves videotaped lectures and video slide shows; the DVJ system is a fully digital Windows-based multimedia delivery system. This study explores how students are currently using the systems to determine potential improvements that could be made to existing and future educational multimedia systems under development at the School of Electrical and Computer Engineering. Emphasis is placed on understanding how students are using the systems on a daily basis by exploring the specific lectures and slides that are being accessed. From this information, a profile of daily media accesses is derived. Also, comparisons are made between expected and actual system usage. The paper concludes with a discussion of future research directions.
