Digitalisation and mediatisation,as important features of the present era,have penetrated into the life of young people in all aspects and at all levels,and have profoundly changed the way of life of young people today.Digitalisation and mediatisation are like a double-edged sword,and their impact on the healthy growth of adolescents is multifaceted and complex,with both positive and negative impediments.Families,schools and society should work together to fully understand the importance and urgency of this impact,and take effective measures to guide and cope with it.
