I teach media literacy at a secondary school in a city on the south coast of Korea. My students are fourteen to seventeen, and they are quicker with a phone than I am. What they are not always quicker at is stopping. A photo comes in, it looks right, it goes out to forty people in a minute.
So I teach the stopping. In class we take a photo, ask where it came from and look for the small clues. We do not shame anyone who got it wrong, because every one of us has. The same method works at home, for a parent, and in a staff room, for a teacher who wants to teach it.
I post one short lesson every Wednesday. Each takes a few minutes, uses an ordinary example and ends with one thing to try. What I sell are the things I use in my own classroom: workbooks, worksheet packs, checklists, step cards and three video courses, one for each of the three groups I teach.
