Technology evolves at a lightning pace in the 21st century. Not only does technology change, but the online spaces begin, morph, and disappear quickly, requiring teachers to be creative and flexible as they work to incorporate technology use into their pedagogy. Today's Tumblr may well be tomorrow's Myspace. As a high school teacher of many years, I enjoyed experimenting with new ideas, including using social media in my classes. I found Twitter to be one of the more useful and easy ways to implement popular social media tools into my English Language Arts classrooms. Using the affordances of smartphones and Twitter, I was able to increase student participation, provide individualized help, and include students in cooperative learning by letting the class experts help other students in a non-intimidating way. With appropriate boundaries for usage and intent, Twitter may offer a new twist for improved student engagement in high school classes that may, over time, lead to greater student achievement.
