As I wrote in my post on the perils of small classes, this past semester I used Google Forms to create a digital ballot for presentation competitions. The ballot worked well — students could hide their votes from other students, and tabulating the results only took a few seconds on my part.
The success of the ballot led me to adopt Google Forms for end-of-semester teammate evaluations. This turned out to be a much simpler method of incorporating individual accountability into collaborative projects than the worksheets I had used previously in a first-year seminar and a capstone course. No time wasted in class while students complete evaluation forms, and no entering of numerical data into a spreadsheet. I create one form for the whole class, which I send out by embedding the link in one email. Google does the rest for me.
Some students failed to follow directions, but that happens regardless of whether an evaluation is on paper or electronic. As stated on the forms I created, I just deleted those responses from the results.
