longer, the Rice administration recommended that we split the
first-edition MOOC into two mini-MOOCs, each lasting five
weeks. The split was accomplished by breaking the original
course into one mini-course covering time-domain concepts and
one mini-course covering frequency-domain concepts.
Numerical examples
As discussed previously, we provide a variety of opportunities for students to explore the numerical/application side
of signal processing through 1) MATLAB examples interspersed in the lecture videos, 2) Office Hour videos, 3) case
studies, and 4) automatically graded MATLAB problems
in homework.
Personnel
Realizing the MOOC took a village, instructor Richard Baraniuk was assisted by Rice DSP research engineer Heather
Seeba, DSP consultant Matthew Moravec, graduate students
Raajen Patel (Office Hours) and Eva Dyer (case studies),
undergraduate student Tan Nguyen (MATLAB homework),
and six undergraduates (forum moderation).
Unique elements
Week 0
Because students come to the class with wildly varying
backgrounds, both editions of the course include an optional
one-week precourse refresher on the key prerequisites in mathematics (primarily complex arithmetic and linear algebra) and
programming (MATLAB). Students can test their preparedness with a pretest (for zero credit).
Integrated MATLAB
ELE301x was one of the first MOOCs to exploit a collaboration with MathWorks that made MATLAB freely available
to students. Through the edX platform, students can access,
within their web browser, a server running MATLAB and even
submit their code for autograding.
