The first question I asked them was:

What is the best academic benefit of using Twitter?

Hearing what my peers think about issues 37%
Learning things I wouldn’t have otherwise 34%
Sharing historical resources 17%
Helping to draw connections between past and present 12%

My students, like most teenagers, enjoyed using Twitter for class, but would likely not use it if I had not introduced it in class. In an effort to dig more into this, I asked the following question:

What would make you use Twitter more?

Easier to see people ‘replying’ to me 31%
Better integration into Facebook 22%
Following more people/orgs who have similar interests to me 19%
Others using it more 19%
Better integration on my mobile device 10%

And then, just out of curiosity, I asked the following:

What ways do you use/follow Twitter?

Web interface (twitter.com) 93%
Tweetdeck 34%
I get emails telling me there’s been an update 10%
App on my mobile device 8%

I also had a couple of open ended questions:
Name one thing on Twitter you’d like to learn more about.
Ideas for 3rd quarter Twitter assignment?

I took these ideas and created our third quarter Twitter assignment.  In this assignment, I also added some appendices to help address the results from above.  For example, I created an appendix that walked students through three ways to see when people replied to them.  They seemed to like the tutorial on how to use a RSS feed email alert to see when people replied to them.

The sample size was 59, or about 90% of my US History students.  I used Google Docs to create a simple form for the students to fill out, it worked great.
