Slideshare was launched in 2006, allowing users to upload files of either PDF, PowerPoint or other types. The site contains millions of files that you can search and download whatever you want. All you have to do is entering the name of the field where you want to find files, such as networks, programming, e-marketing, etc. You can link your account to your account with LinkedIn and Facebook, you can also download the app on your mobile device, and browse all the files from your mobile. This site allows teachers and researchers to communicate through file sharing, presentations, modify them and make use of them according to the nature of their work. Therefore, this book aims to give the trainees skill of using this site and exchanging information among all the participants in the site for the great benefit of the process of learning and teaching for teachers.
