argument 9

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."

作者认为该终止评估系统。因为开始评估后，同学的分数都上升了30%，一些招聘人员认为这些分数很不真实，这也说明了我们的毕业生为什么没有附近的Alpha成功。

反驳：分数上升是有很多因素的，不一定是因为教授害怕被评价很差而故意给的高分来迎合学生，可能是因为学生的评价使老师意识到了自己的不足而改正，学生因此受益，自己的学习提高很多。
○1成绩上升不证明成绩虚假，教师可能改进教学方法。成绩在找工作中不占决定性因素：teamwork communication hard-working。
○2Omega应该和自己以前比，而不是跟Alpha比。样本差异。
○3没有提供切实解决办法，仅依赖于terminate。

(1) 作者没有根据地将评教和分数上涨归纳为一对因果关系。十五年的时间跨度太长，很有可能是其他原因，比如课程改革Curriculum Revolution
导致了分数上涨，或者是教学质量的提高导致了分数的上涨。

(2) 没有根据表明未来的雇主会认为这个分数会贬值，并且作者没有根据地将此归结为Omega毕业生找工作不如Alpha成功的原因。

(3)停止评教的建议是没有说服力的，通常来讲，评教是一种有效的教学评估和促进的手段。作者应该做Omega的评教系统做一个详细的调查，评估出评教和种种假设之间的相关性，否则仓促的计划将不利于学校的教育和学生的未来。

(1) The author fails to rule out other factors that may contribute to the situation that graduates from Omega University are not getting good jobs. For example, school fame, departments, location and so on.
(2) The student evaluation of professors and the rise of overall student grade averages are not causal relationship.
(3) It is not necessary for OU to terminate evaluation of professors in order to enable graduates to secure better jobs. Other factors may help students from OU find better jobs.
(4) The dean fails to mention the positive effects of the evaluation system.
