Interactive solution sets as components of fully electronic signals and systems courseware
The use of computers in teaching signals and systems has evolved. In understanding algorithms, computers were used first as simulation environments and then as real-time implementation environments. In learning the theory of signals and systems, passive tutorial systems have become interactive. Now, software is becoming more and more of an integral part of textbooks and may eventually include the textbook. The paper discusses two interdependent fundamental components of fully electronic courseware-the development of interactive problems and examples, and the supporting software to evaluate student solutions and to explain steps in a correct solution.<<ETX>>
