Valerie's students use post-it notes to add what they learned in class or took away from the lesson to the Tweet Board to be shared out with other students. After students add their post-its to the board, Valerie prompts students to explain their reflections further during a class discussion.
I always like the closure section in my lessons to be short and sweet, and, at one point, I was worried that my closures were ineffective. One of the other first grade ELA master teachers, Laura Quellhorst, showed me how she uses a Twitter poster in her closures. I had my amazing teacher's aide, Jessica Fitzgerald, make me both a Facebook and a Twitter poster so my class could "post" what they took away from our lessons.
Today, I decided we would tweet. We took our Twitter poster out, and I gave each of my students a post-it note. I said, "I want you to tweet about what we learned today and why you think using a timeline is important." I took a picture of some of their responses. This gives me a good idea of what my students took away from the lesson.
