Elisabeth Alkier give a presentation about the book review blog that she developed with her students and her school's librarian Dlo Duvall. The Bode Book Review is a blog authored by students in Elisabeth and Dlo's school. The purpose of the blog is to provide other students with short reviews to inspire them to read new books.
In Elisabeth's presentation she explained the ground rules that students had to follow in order to contribute to The Bode Book Review. Two ground rules that stood out to me were that students couldn't give spoilers in their reviews and that when it came to commenting students were not allowed to correct each other's grammar and spelling. Elisabeth also pointed out that she never corrects students grammar in comments. Instead she gives those corrections privately. Her explanation was that it can be discouraging for reluctant writers to see their work publicly corrected by the teacher. I thought that was an excellent point.
Take a look at The Bode Book Review as a good example of a student and teacher blog. If you want to learn to develop your own blog like it, grab a copy of my free guide to using Blogger in school (link opens a PDF).
This summer I am teaching a five week course all about using blogs and social media in school. There is an option for you to earn three graduate credits for completing the course.
