I have told my students in the Hispanic Civilization course that anybody who refers to Latin America as “a country” or “a nation” on the final exam will get an automatic grade of zero irrespective of how good the rest of the exam is. I don’t care if they do it simply because of carelessness but I’ve had enough of this, folks. Maybe this will finally teach them how to pay attention.
If this seems too harsh to you, please consider that I spend half of the course explaining the differences between Spanish-speaking countries. I show them a map in every single class meeting. What more can I do?
