After reading this article titled, Students Speak Up in Class,Silently, Using Social Media, I am very curious who has tried this type of teaching in their classroom. Basically, a backchannel allows students to use their devices to carry on a discussion during the class by using texting to further engage the students in the topics. I was really surprised at the comments people posted at the end of this article. What are your thoughts? Have any of you used Twitter or a Moodle chat in your lessons?
