IT teachers and tutors joined the "Safer Internet Day" campaign aimed at promoting proper behavior among students when using the Internet. Each of us is responsible for what we do online and how we use it. Safe Internet Day (DBI) has been celebrated on the initiative of the European Commission since 2004 and this year was held on February 11, 2020 under the slogan "Safer Internet Day: Let's act together!". The event has been organized in Poland since 2005 by the Polish Safer Internet Program Center (PCPSI), which is made up of the NASK state research institute and the We Give Children Strength Foundation - the implementers of the EU program "Connecting Europe".
