[LAU] Exam Cheating investigation

I did not mean to send HTML.  Here is a plain text version.



Hello LAD/LAU members:

I teach introduction to western music courses at a local
community college, and one thing I have to deal with is
students cheating by using a smart phone during the
exam.  Sure, I am in the room and occasionally walk
down the aisles, but these enterprising students are still
often able to hide a smart phone from me.

The way these smart phone cheaters are usually caught
is when answering an essay question, they usually
look up the topic on Wikipedia and copy word for word
several sentences.

On these exams, there are a few audio identifications,
and recently one student did a surprising thing.
The audio example was from Pierrot Lunaire, and not only did
answer the question by writing down the title and composer but
she ALSO WROTE DOWN the title and composer of a track by Webern
which was on the original CD that I ripped the Schoenberg
from.

To summarize, from an mp3/ogg file that was put on-line
of one track from a CD, the student was able to identify
_other_ tracks from the CD that were not put on-line.

How did the student do this?  Here are links to the two sound
files that the students had access to:

https://www.dropbox.com/s/z17qoxey9ju4lei/07_20th-pilu_p03_15-18.ogg

Are there some tags embedded in these files?  How would I
be able to see these tags myself?

If there are no embedded tags, how did this student obtain
this information?

Thanks; Ivan
