Background: Just completed my PhD, have to teach one part of a graduate course in EE. Remaining course is taught by another senior prof. Course has two classes, totalling 3 hours per week, and one assignment every week which involves one or more of simulation (SPICE), some programming (MATLAB) and some hand-calculation / circuit design. The assignments are worth 40% of the course eval, the remaining being in-class exams.
How long should each assignment be? For instance, I can design the assignment such that it takes the average student (who has attended the lectures) X hours of effort. How do I choose X?
