In this memo, Omega University's dean recommends thatthe university should terminate its professor-evaluation procedure immediately in order to secure the better jobs for its graduates. To validate this recommendation, the dean points out that Omega encouraged its students, by carrying out a particular procedure, to evaluate the teaching effectiveness of all their professors during the past 15 years . The dean also cites the fact that Omega University's graduates have not been as successful at getting jobs as have graduates from nearby Alpha University, notwithstanding the overall grade average at Omega has risen by 30%. A close scrutiny of each of these evidences reveals, however, that none of them gives little credible support to the dean's recommendation, as discussed below.
To begin with, the dean falsely assumes that Omega's professors mendaciously assign higher grades in their classes for obtaining outstanding evaluations which consequently caused the grade's inflation at Omega. Lacking evidences to confirm this assumption, it is entirely possible that Omega's admission standards, during the past 15 years, has been elevated which has resulted in the grade's increase. Or, perhaps the fact that the quality of education has been ameliorated during this period should be responsible for this increase. Without accounting for these scenarios that might contribute to the grade's increase, the dean cannot justify the claim that the professor-evaluation procedure directly resulted in 30% increase of Omega's students’ overall grade averages.
Secondly, even assuming that the evaluation procedure breeds the grade's inflation at Omega, the dean's claim that Omega's graduates' inflated grades have resulted in their inferior position of finding employments is still untenable. The dean fails to consider other possible reasons for Omega's comparatively poor job-placement. For example, Omega's career services may be insufficient; or perhaps Omega has less job counselors than Alpha. Thus, without ruling out all these possibilities the dean cannot convince me that the inflated grades can hinder Omega's graduates from finding employments.
Finally, even if the dean can substantiate all of the foregoing assumptions, the dean also overlooks a myriad of other possible factors by which Omega can increase its job-placement record. For instance, Omega should improve its public relations or career-counseling services and hire additional job counselors to help its graduates with their resumes and interviewing skills, if by doing so, its graduates can find better jobs. In short, since the dean fails to take into account and rule out these possibilities, the dean's assertion that Omega might help its graduates, only by terminating its professor-evaluation procedure,to have better jobs offers from prospective employers is not persuasive.
In sum, the argument relies on certain doubtful assumptions that render it unconvincing as it stands. To bolster the recommendation the dean must provide clear evidence that Omega's professor-evaluation procedure has rendered the increase in grade average, and the fact that Omega's graduates are less successful in getting jobs than Alpha graduates is attributable to Omega's graduates' inflated grades. To evaluate the dean's recommendation more effectively, I would need more information about Omega's admission standards and quality of education during the past 15 years. I would also need to know what other methods are available to Omega for enabling its graduates to win better jobs. |
