Many of us will be leaving town for a long weekend and the Symposium will be in recess from July 4 to July 8. Do not expect responses from the authors or many of the participants during the recess. However, casual discussion and questions are acceptable. Please contact Professor O'Haver about Internet problems. The designers of the system under discussion are aware that students can easily trick the system, but I do not see any ameliorative aspects or procedures designed into their system for this problem.
Most students are undoubtedly honest, although all students are aware when cheating is possible.
If a system is designed where cheating is riskless and rewarded, a few dishonest students benefit unfairly and all students become unhappy. If the entire system is permeated with opportunities for cheating, previously honest students become cynical and cheating become commonplace. In my opinion, if computer programs are going to be used for assessment of individuals, security and veracity features need to be designed in. These aspects cannot be ignored or discounted by the proprietors. The easiest response is to say that, in the future, things will be different.
