Social media – friend or foe? The answer is complicated and this volume – written by several of the experts in the field – is designed to provide some answers. With every new medium, questions arise about positive versus negative effects. So it is with social media. Topics covered include positive and negative aspects of social media, cyberbullying, sexting, conspiracy theories, media literacy, do social media contribute to ADHD, and should teachers "friend" their students. This is the third and last volume in the MASTERS OF MEDIA series, and like its predecessors, it is designed to provide at least a few answers to this issue and guidance to teachers, administrators, and parents who want and need answers.
