    Awk-Linux: A Lightweight Operating Systems Courseware
    (Institute of Electrical and Electronics Engineers (IEEE), 2008-11-01) Cheng, Yung-Pin; Lin, Janet Mei-Chuen
    Most well-known instructional operating systems are complex, particularly if their companion software is taken into account. It takes considerable time and effort to craft these systems, and their complexity may introduce maintenance and evolution problems. In this paper, a courseware called Awk-Linux is proposed. Awk-Linux can be crafted relatively more easily and it does not depend on any hardware simulator or platform. The basic hardware functions provided by Awk-Linux include timer interrupt and page-fault interrupt, which are simulated through program instrumentation over user programs. Course projects based on Awk-Linux provide source code extracted and simplified from a Linux kernel. Results of this study indicate that the projects helped students better to understand inner workings of operating systems.

    A Constrained and Guided Approach for Managing Software Engineering Course Projects
    (Institute of Electrical and Electronics Engineers (IEEE), 2010-08-01) Cheng, Yung-Pin; Lin, Janet Mei-Chuen
    This paper documents several years of experimentation with a new approach to organizing and managing projects in a software engineering course. The initial failure and subsequent refinements that the new approach has been through since 2004 are described herein. The “constrained and guided” approach, as it is called, has helped to reduce project failure rates, increase specification fulfillment rates, and improve the design quality of student projects. It has also enabled the instructor to evaluate student projects more objectively. The questionnaire survey conducted in this study also shows that students greatly appreciated the new approach because it enabled them to manage projects more effectively.
