How do you get kids to read during the summer?

When I come home from school and I am going about my daily business, I hear "Ding! Ding!" I get a G mail alert that a student has posted a new blog post(the first of several that day) about a book they are reading...at home! Wait a second...I don't give homework assignments, especially not in the summer. These kids are reading, at home, and I didn't tell them they had to? Mind officially blown! I need to figure out what the cause of this phenomenon is so I can repeat it.

Kids are very visual and I think having pictures and embedded links to additional information helps to make this a very interesting tool. We were reading "The Lightning Thief" in English, and learning about Ancient Greece in History when my middle school class was blogging. They enjoyed links to interactive maps, authors' websites, mythology pages, and quizzes to find out which Greek god was their parent. Again, I think that the teacher curating high interest and informative content within their blog posts affect how interested the students will be in the blogging. I also think it is important for the teacher to comment regularly, modeling scholarly talk and questioning. If you look at my class blog, the post titled "Blogging for Beginners: Growing the conversation with follow-up questions" and "Welcome to Kidblog" talk about blogging etiquette, but most of that teaching happens in class through mini lessons before writing, or through comments made by me on their posts, when I see a "teachable moment". I don't think kids would be that interested in reading a post about rules for blogging, unless maybe I could find a cool infographic, or an animated video on the topic. I'm still looking. Edutopia has a nice list of digital citizenship resources.

7 P.M. on a Friday of a 3 day weekend and I have gotten eight G mail notifications while writing this post because my students are at home talking to each other about books. Thank you, technology!
