...a c t The ubiquity of social media (e.g., Facebook, Twitter) is no more apparent than at the university. Social media are increasingly visible in higher education settings as instructors look to technology to mediate and enhance their instruction as well as promote active learning for students. Many scholars argue for the purposeful integration of social media as an educational tool. Empirical evidence, however, has lagged in supporting the claim. Most of the existing research on the utility and effectiveness of social media in the higher education class is limited to self-reported data (e.g., surveys, questionnaires) and content analyses. This paper summarizes the scholarly writings as well as reviews the findings of empirical investigations. Some limitations are discussed, and future areas of research are proposed. Ó 2013 Elsevier Ltd. All rights reserved. 1. Introduction The growth of social media and other Web 2.0 technologies is unprecedented (Lenhart, Purcell, Smith, & Zickuhr, 2010). Social media technology has become an essential part of personal life as users generate content, share photos, choose to ‘‘like’’, or interact in a game.

...Chapter 1 THE PROBLEM AND ITS BACKGROUND Introduction Social media had been a massive part in every household. Technology had given us a great deal and helped us with our tasks and made everything easy. We know that social media sites like (Google+, Twitter, Facebook and Yahoo) had introduced us in many methods that can connect people easier. Social media sites had been a popular means to connect with other people over the Internet. During the 1980's home computers were becoming more common in every household and social media sites were becoming more refined. According to Hendricks, (2013) The Internet relay chats, or IRCs, were first used in 1988 and were popularized into the '90s. The first popular social media site, Six Degrees, was created in 1997. The site enabled its users to upload a profile and make friends with the other users. By 2006, Facebook and Twitter both became available to users throughout the world. These sites still remain as the most popular social network on the Internet. After the success of these social media sites, other sites like Tumbler, Spotify, Foursquare and Pinterest began appearing to fill specific social network niches. Furthermore, Hendricks (2013) emphasized that, "there are a tremendous variety of social networking sites, and many of them can be linked to allow cross posting. This creates an environment where users can reach the maximum number of people without sacrificing the intimacy of person-to-person communication. We can only speculate...
