I take my writing classes to a computer lab 4-5 times a semester. On these days we're researching, doing annotated bibliographies, composing some early paragraphs, and sharing them on a big screen in front of the lab.
It works great and it's become an absolutely integral part of my schedule.
I have 2 of these intro classes and they meet back to back on Tuesdays and Thursdays, 9-10:30 am and 10:45-12:15 pm. We have a ton of labs, and I've never had a problem finding time.
Our lab scheduling is done electronically and for Fall semester the online notice that we could begin entering our requests came to me on July 12th at 2 pm. By 2:30 that day I had all of my requested dates in. Here they are:
Sept 17: 9 am - 12:15 pm
Sept 24: 9 am - 12:15 pm
Oct 29: 9 am - 12:15 pm
Nov 12: 9 am - 12:15 pm
Nov 19: 9 am - 12:15 pm
Yesterday, more than a month after I submitted my request, here's the schedule I got - some of the days, you might note, if you're anal like me, are not Tuesdays or Thursdays...
Sept 17: 8:30 am - 11 am
Sept 25: 9:30 am - 1 pm
Oct 29: 9:30 am - 10 am & 12 pm - 1 pm
Nov 13: 11 am - 12 pm
Nov 19: 9 am - 11 am
I feel as if I'm being punk'd or something.
