WHO refers to infodemic as “an overabundance of information – some accurate and some not – that makes it hard for people to find trustworthy sources and reliable guidance when they need it.” Teaching students the skills to evaluate the reliability of online information and to exercise critical thinking is vital for survival in the infodemic era when misinformation is paramount. In this seminar, I will share the design and adaptation of different sources of material, particularly the Civic Online Reasoning curriculum, in teaching online reasoning and critical thinking in an academic English course for upper-intermediate level students, and tips for igniting students’ curiosity and engaging them in interactive communication.
