Systems and signals online questions and grading

In this paper we present an e-learning solution, adapted for online generation of questions for students self study for the new systems and signals course. The systems and signals course was classically focused on electrical engineering but the Berkeley approach radically changed this view and produced a new course that spreads to different areas like mechanical or computer science engineering. We developed an original framework for this new course that consists of a set of more than 20 generic questions with more than 100 variations each. The students may freely use this framework for self study. For grading, the quizzes are sent to the student´s personal area and the grading is immediate and automatic. Results, from other courses where this framework is being used for automatic grading, show that it actually helps the students to follow the course along the semester rather than concentrating all the work on final exams
