不好意思我忘了写题目,谢谢啦!
Argument 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.'
outline
1. the dean unfairly assumes that the evaluation of the professor by students accounts for the improvement of the grades.
2.the dean confuses cause-and-effect relationship with a mere temporal sequence between the rise of the grades in Omega University and their graduates' inseccess of getting jobs when they are contracted with the Alpha University.
3. the dean assumes that terminating student evaluation of professor is the only available solution to help its graduates to get better jobs, but there is no sufficient evidence.

Argument 9
The dean concludes that to enable the graduates of Omega University to secure better jobs, they should now terminate students evaluation of professors. In support the conclusion the dean points out that the evaluation of the professor by student makes professors give higher grades and the inflation of the grades contribute to their graduates' insuccess of getting jobs contracted with nearby Alpha University. The Argument appears plausible, at the first glance, however, strict scrutiny reveals that it is unconvincing.
In the first places, the dean unfairly assumes that the evaluation of the professor by students accounts for the improvement of the grades. However, the dean provides no evidence to support that this is the case, nor does the dean establish a causal relationship between the evaluation of professor by students and the rise of the grades. It is highly possible that other factors might contribute to the rise. For instance, the improvement of the academic performances of Omega students, they indeed should obtain the deserved higher grades. Professor in the Omega University spend more time on the teaching or the quality of the teaching become better, and then students learn more form their teachers and perform well in their academic activities. It is likely that 15 years ago the professor give the lower grades to their students than other university, because some reasons they realize that they should give the students higher grades to enable their grades equal the students' in other university, which is responsible for the rise of grades in Omega University in the past 15 years.
Secondly, the dean confuses cause-and-effect relationship with a mere temporal sequence between the rise of the grades in Omega University and their graduates' inseccess of getting jobs when they are contracted with the Alpha University. A significant temporal relation between two events is one indication of a causal relationship between them. However, it per se does not suffice to prove such a relationship. It is possible that other factors might have caused the insuccess of getting jobs. Maybe Alpha University is a famous University, and its graduates consequentially and easily get jobs. It is likely that Alpha University implements some measure to help their graduates to perform well when job-hunting, for example, some course about job-hunting and skills of interview. There is no evidence that the professor in Alpha University give their students lower grades which contribute to their success in job-hunting. Unless the dean also consider and eliminates all other plausible causes of the graduates of Omega University insuccess of getting job, the argument is vulnerable to criticism.
Last but not least the dean assumes that terminating student evaluation of professor is the only available solution to help its graduates to get better jobs, but there is no sufficient evidence. As we all know getting better jobs is related to some factors such as the skills of interview, the information of job market and the ability of their graduates when they work. The dean does not persuade that terminating the evaluation of professor can bring the success of getting better jobs. Moreover the dean ignores the positive effect of the evaluation of professor by students. It is possible that evaluation of professor can promote their faculty to inspect themselves and improve their teaching work. If they terminate the evaluation of professor, they will lose the supervisory effect for teaching.
In conclusion, the argument is not persuasive as it stands. To bolster the dean would have to provide the evidence that (1) the evaluation of professor by students is responsible for students' rise of the grades (2) the inflate of grades in the Omega University accounts for their graduates' insuccess of getting jobs contracted with Alpha University (3)terminating the evaluation of professor by students can availably lead the better job-hunting of their graduates. |
