We propose a web-based collaborative education system (named BRIDGE) that promotes the use of high-quality, open-source code examples as educational materials to connect theories and practices of software engineering and computer science. BRIDGE promotes an innovative approach to answer the educational challenges in software engineering. It is comprised of three integrated subsystems: a code annotation system that provides an effective way to share the understanding of opensource code examples; a collaborative educational material creation system that helps build educational modules capable of connecting theories with realworld examples; and a collaborative course management system that allows educators to construct innovative courses based on the educational modules. BRIDGE encourages participation and collaborative knowledge sharing of software engineering professionals, educators, and students. BRIDGE is driven by this participation. The system will help students learn both technical knowledge and nontechnical skills highly desired in modern software engineering practices.
