We use our classroom blog for sharing our learning experiences. An important part of the learning process involves reflecting on our learning. One way I get my students to reflect is to do self-assessments. It seems to me although many teachers are using web 2.0 tools for teaching and learning, not many are taking the many opportunities to use them for assessment.
Our most recent ICT venture of recording readers theater podcasts was posted on our blog so that we could share our work and get reflective feedback. As my students read blogs and comment on them as a reading task, it seemed a good place to embed a form that would serve as a reflective assessment.
Why I like using Google Forms rather than services like Polldaddy is that it is easy to set up and embed, but more importantly it sends all the poll data to a Google Spreadsheet in Google Docs. From there you can get your data presented in various chart or pie displays with a few button clicks. Of course you do need to sign up for a free Gmail account, but then in my opinion if you are not already using Gmail you should be.

Some other online poll and testing services are Yacapaca, Zoho, and Mystudiyo.
