The journal article summarizing the study and our findings is available online at: onlinelibrary.wiley.com Abstract Despite the widespread use of social media by students and its increased use by instructors, very little empirical evidence is available concerning the impact of social media use on student learning and engagement. This paper describes our semester-long experimental study to deter-mine if using Twitter -- the microblogging and social networking platform most amenable to ongoing, public dialogue -- for educationally relevant purposes can impact college student engagement and grades.
