A free course that equips students with the skills to spot falsehoods and manipulated media and to reflexively question what they see online. Aimed primarily at university students, it covers the essential concepts and processes of fact checking, source evaluation and critical thinking in the age of online conspiracies and generative AI. Presented by RMIT lecturer Sushi Das, the course is modelled on RMIT's Australian-first fact-checking "micro credential", which has been updated and made free to the public.
