inserting annotations into an audio file?

Hello all --

In my classes, students are often asked to write narrative responses to
questions (e.g. "explain why something-or-other is true"). I have a
dysgraphic student who, with my encouragement, is submitting audio files
rather than written responses to all narrative questions. (For this
particular student, word processing isn't an effective option. We've
tried it, and it seems that regardless of the writing medium, he simply
has trouble getting ideas from his brain into words. He is incredibly
expressive and clear when speaking, which is why we're trying oral
responses.)

So here's my dilemma. Say that the student has submitted a 2-minute
audio file that I want to annotate with comments. I'm struggling to find
a good way of doing this. Right now, I'm giving him written comments in
which I indicate a time code followed by the comment. For example:

"At 0:52, you claim that the survey contains both undercoverage and
voluntary response biases, but you only explain why undercoverage
exists. You also need to explain why you think there's a voluntary
response bias."

I find this method of annotating rather clumsy. Is there any way of
inserting an audio or written comment directly into an audio file? Right
now, we're using Audacity, simply because that's part of my school's
standard student laptop image (we're a 1:1 laptop school), but neither I
nor the student are wedded to that particular program.

Many thanks in advance for your advice and suggestions.

Sincerely,
Dave Wang

We are all agreed that your theory is crazy. The question that divides
us is whether it is crazy enough to have a chance of being correct.
