9. The following appeared in a memorandum from a dean at Omega University.
"Fifteen years ago, Omega University implemented a new procedure that
encouraged students to evaluate the teaching effectiveness of all their
professors. Since that time, Omega professors have begun to assign higher
grades in their classes, and overall student grade averages at Omega have
risen by thirty percent. Potential employers apparently believe the grades
at Omega are inflated; this would explain why Omega graduates have not
been as successful at getting jobs as have graduates from nearby Alpha
University. To enable its graduates to secure better jobs, Omega
University should now terminate student evaluation of professors."

In the memorandum, the dean suggests terminating the evaluation of professors to secure its graduates better jobs , for he believe that it’s the professor evaluation that led to the so-called inflated grades, thus causing graduates from Omega University(O) less successful at getting jobs than graduates from Alpha University（A）. The dean’s p seems somewhat reasonable at the first glance; however, further analysis reveals several severe logical problems.
Citing that since the evaluation began O’s professors have begun to assign higher grades, the arguer assumes that it’s the desire for better evaluation that motivates professors to give students abnormal high grades. However, this assumption is a bit too harsh. Firstly, we cannot assert that it’s the evaluation that caused the grade increase which in the dean’s opinion is quite irregular just because the former happened before the latter. Nevertheless, many other factors might have caused the increase as well. Secondly, even if the evaluation do have contribute to the grade increase, that might not be that terrible as the dean believes, for it is highly possible that the evaluation procedure have helped screen away those not-so-good professors and motivate professors to improve their teaching abilities thus enhancing the whole education quality. If this is the case, the dean has just mistaken the effective evaluation.
Even if the dean’s indication is the
the case, a second thought about whether the grade growth is inflated at all is still needed, for without a comparison of grade growth with others we just cannot accuse O’s grade growth as anomalously high. Common sense tells me that the evaluation has been adopted by most colleges but not only O itself, thus professors in other colleges might also assign higher grades just like O’s professors have done.
Actually, the average growth of the whole might even be higher than O’s, if so, O’s grade has actually fallen. Or maybe, the average growth is just a bit lower than O’s. In either of these cases we just cannot accuse O’s grade growth is too high, let alone inflated.
Even assuming O’s grade is inflated, it might not be the main reason why O’s graduates are less successful than A’s. Perhaps, grade of A is also inflated, if so, we see no sense in charging the inflated grade as “job killer”. Moreover, many other factors are more important in determining job condition of one college, such as the good-job majors, powerful alumnus and alumna, whether the college is famous at all, whether the college’s job hunting programs are effective, etc. It is highly possible that compared to O, A is more famous, or it has more good-job majors, or more effective measures to help its graduates find better jobs. In any of these cases, rather than canceling the evaluation O should firstly make up for those fallacies.
In sum, the dean lends little support to the proposal. To better support the statement, the arguer must provide more convincing evidences that evaluation has impelled an unjust grade increase and compared to the average the increase is indeed inflated and unacceptable. Moreover, more information about O and A is also needed to recognize whether the grade increase is the main cause for job hunting differences. To better evaluate the suggestion, we would also need a more thorough analysis of the gain and loss of terminating the evaluation. |
