Web-based platform for problem-centered learning in DSP
Gregory A. Krudysz, James H. McClellan · 2011
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..
