STEP 4: Choose the format
What are you good at and what do you like to do? Do you like to vlog or are you inspired by Louis Theroux? Then you may consider making some video recordings or taking an interview with a teacher in your host country who inspires you or makes you think.
Always trying to take the perfect pictures? Why not a photographic series about interesting teaching practices?
A born entertainer? Maybe you should think about an educational game where other students may learn from!
