We can't deny that the use of new technologies at school is a change, and every change can create a trauma due to the fact that it requires some effort, adaptation until we get used to it. Then, those changes become natural, a habit. We all have experienced a lot of changes regarding the Educational System in Spain, as well as in textbooks, which update every year.
So, new technologies allow us to extend the learning field (Facebook, web pages...). The next thing we have to take into consideration is the student; our students are creative because they 'create', share, etc. New technologies ease creating links between people and communication.
In my opinion, tehcnology is deeply important when teaching English, and not only with teenagers. Little children learn throughout Youtube links, films projections. Regarding Primary students love learning through songs with lyrics, powerpoint slides, online exercises and games at home, etc.
Nowadays, teenagers are used to communicate with each other through Social networks, Blogs and teachers have to take profit of it to make the learning more dynamic and interesting.
