A COLLABORATIVE PROJECT ON JAVA-DSP INVOLVING FIVE UNIVERSITIES

Abstract - This collaborative effort involves five universities, namely, Arizona State University, the University of Washington-Bothell , the University of Texas at Dallas, the University of Rhode Island, and the University of Central Florida. The paper describes educational technology innovations and software extensions that enable the on-line software Java-DSP to be used in three courses at five different universities. Assessment from use at ASU is presented in this paper. Preliminary assessment from the other institutions is also available. A new concept for concurrent collaborative laboratories is also presented.

INTRODUCTION Java-DSP (J-DSP) (http://jdsp.asu.edu) is an educational program that enables on-line simulations and web-based computer laboratories. J-DSP is based on an object-oriented programming environment that enables students to establish and run DSP simulations on the internet. The initial version of J-DSP has been developed in the ASU MIDL lab and tested in a senior-level Electrical Engineering Digital Signal Processing (DSP) course (EEE 407). The J-DSP Version 1 (CD-ROM ISBN 0-9724984-0-0) is approximately 42,000 lines of Java code. Papers on J-DSP addressing several DSP related areas have been published previously in archival conference proceedings and journals [1-15]. This paper presents sponsored work aimed at developing, disseminating, and assessing several new J-DSP capabilities. The project involves five universities and includes significant educational technology innovations that enable Java-DSP (J-DSP) [1] to be used in 4 courses at 5 different universities. The project tasks consist of the following: a) educational innovation that upgrades the J-DSP GUI, b) a software development task to extend the mathematical and signal processing functionality of J-DSP, c) a comprehensive on-line laboratory exercise development task engaging all the Co-PIs at the different universities, d) a dissemination and assessment plan that involves five universities which committed to testing and providing feedback on the new J-DSP GUI and all exercises and content, e) a comprehensive pilot test of a new multi-site laboratory concept that allows students in the five universities to run real time distributed on-line simulations, f) dissemination of all results, practices, and concepts developed

ASU is the lead university, and will execute all the software development tasks. The ASU group will also develop exercises, assessment instruments and dissemination materials. UWB will develop and assess all the computer exercises on the Multimedia Computing course; URI, UCF UTD will work on their Signals and Systems courses.
