Vocal Marking


I'm about two thirds of the way through my audio marking of my CE317 students' Lua assignments. So far, it's going a lot better than I was expecting.

The students get feedback they might recognise as being feedback.
It turns out it's slightly quicker to comment verbally than to type up comments.
I don't feel obligated to fix the bugs I detect in the programs.
If I make a mistake (eg. say something isn't there when it is), the students will pick that up.
There's more detail in verbal comments, so the feedback is of higher quality.

It's killing my voice.
I can expect students to disseminate what I say to them, editing it to make it sound as if I'm a jerk and so on.
Sometimes I say things I wish I'd said a better way.
Laughing at bad code is probably not going to go down well.
I can't mark wherever I am, for example on the train for four hours tomorrow.
I have to figure out a way to get the .mp3 files to the students.
I can't tell the students what mark they have in the audio file because I haven't figured it out at that point.

So far, only one student has lost marks for mis-spelling "lose".

Next year, I think I may drop the slides on table.remove and table.insert from my lectures, to discourage students from designing bad data structures just to use them...
