Another important element to consider about student blogging is how to assess their work. Student blogging shouldn't just be a fun add-on activity, it should be a core part of the reading & writing work done in class each week. Therefore, it is essential to develop a clear, concise rubric for blogging & commenting that will help develop your student writers and give them a platform for self-evaluation as well.
I have developed the rubric below for use with grades 3-5. It is primarily based upon Clarence Fisher's blogging rubric with additional credit to Sylvia Rosenthal Tolisano and the University of Wisconsin-Stout. I hope that you can adapt it for use in your classroom as well. Click here for the link if you would like to make a copy of the Google Doc to edit it for your classroom needs.
