What does it mean to be literate in the 21Stakeholders around the world are gradually embracing an expanded definition for literacy, going beyond the ability to write, read and understand words. Media and Information Literacy (MIL) emphasizes a critical approach to literacy. MIL recognizes that people are learning in the classroom as well as outside of the classroom through information, media and technological platforms. It enables people to question critically what they have read, heard and learned.As a composite concept proposed by UNESCO in 2007, MIL covers all competencies related to information literacy and media literacy that also include digital or technological literacy. Ms Irina Bokova, Director-General of UNESCO has reiterated significance of MIL in this media and information landscape: “Media and information literacy has never been so vital, to build trust in information and knowledge at a time when notions of ‘truth’ have been challenged.”MIL focuses on different and intersecting competencies to transform people’s interaction with information and learning environments online and offline. MIL includes competencies to search, critically evaluate, use and contribute information and media content wisely; knowledge of how to manage one’s rights online; understanding how to combat online hate speech and cyberbullying; understanding of the ethical issues surrounding the access and use of information; and engagement with media and ICTs to promote equality, free expression and tolerance, intercultural/interreligious dialogue, peace, etc. MIL is a nexus of human rights of which literacy is a primary right.Learning through social media In today’s 21The Policy Brief by UNESCO Institute for Information Technologies in Education, UNESCO MIL CLICKS - To think critically and click wiselyFor this reason, UNESCO initiated a social media innovation on Media and Information Literacy, MIL CLICKS is a way for people to acquire MIL competencies in their normal, day-to-day use of the Internet and social media.

A recent UNESCO publication described the high relevance of “Citizen's engagement in open development in connection with the SDGs are mediated by media and information providers including those on the Internet, as well as by their level of media and information literacy. It is on this basis that UNESCO, as part of its comprehensive MIL programme, has set up a MOOC on MIL,” says Alton Grizzle, UNESCO Programme Specialist. UNESCO’s comprehensive MIL programmeUNESCO has been continuously developing MIL programme that has many aspects. The first step on this road from policy to action is to increase the number of MIL teachers and educators in formal and non-formal educational setting. This is why UNESCO has prepared a model The mass media and information intermediaries can all assist in ensuring the permanence of MIL issues in the public. They can also highly contribute to all citizens in receiving information and media competencies.
