Getting students to stay on top of work and pay attention in class can be challenging. And with social media and laptops it's even more difficult, but it doesn't have to be. Rather than fight social media, some professors at Dakota State University decided to join Facebook.  Even students are surprised by all of the benefits. Having students on Facebook and Twitter during a class may sound like a nightmare for teachers.  But some are finding ways to make social media work in and out of the classroom. "About three semesters ago, I started using Facebook groups for my classes.  I use that to post events so students would know when homework, quizzes and tests were coming up and due, as well as communicate between students and myself," Assistant Professor at Dakota State University Chris Olsen said. Other professors also have profiles.
