Get Your Students Hired
To understand how pieces fit together, Subjective seems to almost always be the better option (at least in my courses). But it is not always time feasible to have multiple subjective evaluations, especially those that would show a spectrum of items learned. (Discussions tend to help fill the void in terms of Assessing comprehension, but I have found that in a design class like mine, an essay that accompanies and explains a project really covers the bases in terms of Evaluation.)
