MallardTM: an educational tool for digital signal processing

Mallard/sup TM/ is a World Wide Web-based interactive learning environment suitable for virtually any subject. We focus on its application as an educational tool for digital signal processing basics. Students are tested via interactive quizzes with instantaneous problem correction and grading. Intelligent grading programs not only assess the correctness of a response but also determine why an answer is incorrect. The student receives immediate feedback and can access online assistance if desired. The instructor benefits from a number of administrative utilities, the most important being automatic grading and maintenance of not only the gradebook but also detailed logfiles. Mallard/sup TM/ does this within a secure environment, using Netscape's Commerce Server. Access is restricted by password, and communication is encrypted.
