This handbook prolongs the invitation to investigate and to question the media developed in other sections of this kit. It focuses on the Internet and navigation on the networks. It places the Internet in a media continuum, to which it brings an additional feature, interactivity. The Internet is an interactive environment of communication and information that provides access to different modalities of exchange and to an infinity of traditional print and audiovisual media. In media education, it has become essential for all to be capable of finding information–to search, retrieve and process data - and of providing information - to produce and circulate data. (Self)informing is part of (Self)educating. The handbook thus recombines the key-concepts, the repertoires of strategies and the suggestions of activities in the form of practical fact sheets. These are not recipes but ideas for further explorations, on-line and off-line.
