Comment
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.
Pros:
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.
Cons:
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...
