While teachers in Finland are required to teach media literacy, they have significant discretion over how to carry out lessons. Mrs. Martikka, the middle school teacher, said she tasked students with editing their own videos and photos to see how easy it was to manipulate information. A teacher in Helsinki, Anna Airas, said she and her students searched words like “vaccination” and discussed how search algorithms worked and why the first results might not always be the most reliable. Other teachers also said that in recent months, during the war in Ukraine, they had used Russian news sites and memes as the basis for a discussion about the effects of state-sponsored propaganda.
