The discussion on test/retesting, scoring, and averaging turns on two disparate questions…
a. What information or skill has the student mastered?
b. How does the student routinely apply himself to his work?
I hear many employers wishing they could find employees who are strong in (b). If only they could hire people who will actually show up for work, apply themselves, and work, they can teach the necessary job skills, which may require some (a).
Somehow, our grading must include results showing (b). If not, we could well graduate students with all the (a) but still unemployable.
So, a big question is…are we satisfied to post grades that show what a student does know and can do(if he wants to) on a test? Or does the grading also include a factor showing what a student does do, routinely?
