99Polls is a quick and easy way to get information. In under five minutes I was able to create and post a poll to my blog about Twitter and Teachers. You sign up for free and get started. Your homepage collects all of the data from your poll. This is great if you have polls set up on your blog, school homepage and any other locations. I love to get feedback from my students about lessons that I have taught, but I always feel they hold back because they do not want to offend me. It is really important to assess your own lessons, but feedback from the students is something teachers should not shy away from. The harshest criticism can help create the best lessons.
Try using this simple site to gauge the learning of a particular lesson one day. You might be interested is the response you get from your students. This is just another great and easy way to make the classroom a better place.
