Identidad digital en redes sociales

The dissertation paper is dedicated to a didactic project designed applying the project-based language learning methodology to work the linguistic and the digital competences. It is a result for a gap found during the internship periods, which was highlighted in the course of the global pandemic as educational institutions were compelled to adapt to online teaching. Generally speaking, academic institutions are integrating 21st century tools, however, not all staff was trained or prepared to teach online. This issue did not affect only educators, students too, especially these in difficult economic situations because they did not have basic conditions to connect to classes. The project aims to raise awareness about digital identity and social networking sites among teenagers of 1st of ESO course. The use of the internet creates an identity for each user, and if this is not protected, it might be damaged. This becomes a serious matter when it comes to the use of social media. Teenagers will be able to teach about online risks to younger generations, like role models.<br /
