The role of Facebook in elementary school education

In National Curriculum Framework for pre-school education and general compulsory and secondary education (November, 2011) it has been suggested the usage of social networks with parent/teacher control in the first cycle (from the first until the fourth grade of the elementary school). Since informatics is optional in elementary school and it is most commonly held from fifth to eight grade, there are certain problems in the execution: should the first four grades primary school teacher actually teach informatics (in that case, they should be prequalified) or will it be held by the certified informatics teacher who is already teaching higher grades in elementary school, forced exposure of students from the age of 7 towards social networks, books which didn't cover security of social networks, the ethical question in the teacher - student relationship and finally the law concerning children using social networks. We live in the time where employers partly rely on the profiles from social networks during employment process and we give away personal information online without us knowing when and where it will be used against us which lead us to raise our awareness about the Internet in general starting from elementary school.
