Rubrics are a relatively well understood assessment instrument,
although it doesn't appear to be heavily used in CSE. "Learning
increases, even in its serendipitous aspects, when learners have a
sense of what they are setting out to learn, a statement of explicit
standards they must meet, and a way of seeing what they have
learned." [Loac86] "Assessment requires [faculty] to articulate...
explicit and public statements of criteria of performance. By doing
so, faculty refine their own understanding of expected abilities,
clarify for their colleagues the basis of their judgment, and enable
students to understand what performance is required."
