Michael, using any form of assessment as a means to modify behavior is more a show of a lack of skills on by the instructor than anything positive that will come out of the student learning side. There are simply too many quality instructors that are able to get good results from their students without the use of this form of behavior modification. For those that feel using tests is an effective use of assessment tools I highly recommend you take some time to review the literature on this subject.
