Design and Development of "Signals and Systems" Web Course System

The network-based teaching, of which the advantanges have been well recognized, has gained popularity in recent years. In this paper, we present an overview on the newly developed "Singals and Systems" courseware. Benefiting from its hybrid structure, the courseware facilitates asynchronous self-determination study, synchronous interactive study, and individualized learning. A wide range of topics relating to the structure and functionality of the courseware, including system-navigation, searching, problem discussion, testing, and the techniques employed for its implementation, such as multimedia technique, database technique, CCS and PHP etc., are described.
