Somewhere in my stash of useful links there was this old BBC pilot of the ‘Evidence Toolkit‘ – a piece of software for helping teens learn to spot fake news. The pilot has ended, but if you scroll down the page, you will find a rather useful set of materials: three ready-made lesson plans with activities about verifying sources, interpreting images and data (for example, Lesson 3 has a fun video about ‘Numbers and the tricks they play’) and other aspects of reading the news. There’s even an interactive game from Aardman (BBC iReporter) – I haven’t used it yet, but it looks very promising. As for the age and level, the text-based activities would probably work best for higher-level older teens: after all, they were not written with EFL learners in mind; the videos and games seem more universal. Just another resource that can really save teachers some time!
P.S. If you’re looking for more materials for critical thinking, you can find a useful test if you travel this way.
