Web-based platform for problem-centered learning in DSP

In this paper we present a web-based tutoring system designed to enhance a student´s conceptual understanding by providing many concept-centered exercises. The system relies on a course textbook from an introductory Signal Processing course for knowledge representation, and also on a large database of relevant problems. We construct concept maps from the textbook to create meta-data for various textbook derived resources, as well as for tagging all the exercise questions. The system tracks each student´s comprehension of the course material by evaluating the student´s problem solving proficiency in terms of the concepts from the textbook..
