Last year, I was offered to teach a class called on grammar and structural linguistics, which I accepted with some hesitance because I considered it a bit outside of my comfort zone. I've taught sociolinguistics and communications courses before, but this is hardcore linguistics, requiring knowledge not just of grammar but also of how to analyze the syntactic structure of sentences using grammar trees. What made it even more intimidating was that these were four hour courses, and I had to make it interesting to the students. Games, then.
