The concept of literacy education has changed as technology has evolved. It is no longer enough to teach students how to read books and write on paper. This won’t adequately prepare them for their 21st century lives. Blogging is an authentic way to teach both traditional reading, writing, speaking and listening, as well as multi-modal 21st century skills. I think a class blog is an excellent way to set homework that is more relevant to what you are learning in class than a photocopied sheet of paper. Online conversations are far more valuable. Getting parents on board with the younger students or weaker readers is important but these students are not any better off with the traditional photocopied worksheet. There is also the option of posting or linking to teacher made video or audio explaining tasks or concepts.
