However, there is something that we get by in 21th century : Social Media. It is unique and only used via internet. Wikipedia says that social media refers to the means of interactions among people in which they create, share, and exchange information and ideas in virtual communities and networks. People are not only receivers any more, they are also users. They don't passively receive messages which is produced by sources such as media barons, governments, advertisers or associations. Receivers give feedback to source and that makes them a source, too. They have a reciprocal relationship and direct each other.
Every single person can use social media tools like Facebook, Twitter, websites of blogs, Pinterest, Flickr, Foursquare, Google+, Linkedln, Myspace, etc. Most known and used social media websites are Facebook and Twitter. Twitter is kind of a micro blog website, in which people share anything they want, interact with another people and write down what they feel or think. Also, lots of companies or official associations and opinion leaders use these social media tools. This technology and incredible network turn the world into a village : The Global Village.
Education should be adapted to changes in the world. Technology takes an important part of these changes. Unless educators accept that innovations and reforms are important, they will be behind the time. The youth is very interested about social media. It can attract their attention to the lectures if it can be used affectively. It is up to the lecturers, who should be experts of media literacy. They should know what they can do with social media and should teach how to use it properly.
People should always be well-educated in subjects they teach other people. That is the key of success. Without this, it would all be useless.
