I work in education technology, and have full access to our web based course delivery system, which about 25% of our classes use to some degree or another (syllabus only to fully online).

I once had a student claim that she had logged in, taken several tests, and gotten scores/grading results, but the system didn't record it. I ended up sitting down with her, her instructor, and one of the registrars and teaching 'em how to read web server logs, using logs from the date in question. I showed them what the logs look like as someone goes thru the process of logging in, accessing a class, accessesing a test, viewing questions, saving answers, and getting a grade. I then pointed out that there was *nothing* having to do with her username during that period, and *nothing* coming from the specific lab she claimed to be in.

She then tried to convince the registrar that I was lying or (and these are her exact words) "little green men came and removed my lines from the files".

Turns out that she was in cahoots with the student employee who did check-in/out duties for the lab she claimed to have been in....
