I am a student and I recently had an incident where one of my professors asked for a midterm evaluation. Although, the evaluation was anonymous, so no names were attached to it, somehow the professor was able to attributea number of critical comments I made in the 'anonymous' evaluation to me! I've checked with the I.T. support staff at my school and they've assured me that the evaluation was set to 'anonymous'. However, the only other way that the professors could have known it was me was by cross referencing my activity time with the time the evaluation was submitted.
It is a graduate seminar, and there is only about 15 persons in the class. We were given a couple of weeks to submit our evaluations and my thinking is that it was very easy for the professor to know who submitted which evaluation, by simply looking at the students activity log sheet and the time when the evaluation was submitted. The anonymit of evaluations really depends on the instructors acting in good faith by not cross referencing the two logs.
This is a serious flaw in the software and I was wondering if there is work being done to correct that (i.e. time-delayed submission times for evalautions)? I've brought this up to the I.T. staff at my school and I think there is a recognition that this is a problem, but they're a bit hesitant about taking this issue on.
