Multi-platform CBI tools using Linux and Java-based solutions for distance learning

This paper presents a set of software tools developed to enhance local and distance learning for speech and signal processing classes. The multi-platform paradigm is stressed in both computer-based instruction (CBI) and World Wide Web (WWW), Java-based tools. The CBI speech tools are a package developed to enhance a graduate course in digital speech processing; the tools may be run on various platforms and will benefit local or distance learners taking the course via teleconferencing. Students may gain “hands-on” experience using this package on their own personal computer (PC) or a university computer. The WWW, Java-based tools have been designed to be used for interactive homework in signal processing classes but also have a wide range of applicability. JavaGram is the name for the currently developed application that allows students to easily “turn-in” homework diagrams, such as signal-flow charts, via the WWW. This is an improvement over past systems that use only forms in WWW homework for remote classes. These tools have been found to greatly enhance local and remote offerings of a course on speech signal processing
