           In this article they talk about a study that was done that showd a link between Twitter and student engagment and grade-piont average. They (The Journal of Computer assisted Learning) did the study on 125 college students. They found that the students that used Twitter got on average half a point higher and particpated in class more then the students that did not use Twitter.
            I found this article hard to believe at first. I myself have never had a twitter account and I don't know how exactly it works and most the people that I know that have a twitter account do not have that good of grades. But after I thought about it, I realized that the people that have twitter accounts usually like to know everything and would probably not be afraid to ask questions in class and like to learn new things and follow them.
