I teach English to college students who don't want to learn English. I teach Freshman Composition. It is a required course, which means all students have to take it, whether they are majoring in math, science, computer engineering, architecture, medicine, or underwater basketweaving. Very few are majoring in English. Very few want to be in the room. Very few see any point in taking English AGAIN. They've taken it every year they've been in school. They speak (at least most of them) English (I do get some non-native speakers sometimes), or some variation of it, so enough already. My classroom is the last place they want to be.
My son and daughter-in-law had been after me for years to move from upstate New York to North Carolina. "It's so cold up there," they said. "Things are hopping down here," they said. "You'd find a job in no time, and you'd love the winters."
For the last 34 years, I've attempted to teach English to students who, for the most part, do not want to learn English. Have you ever tried to teach a puppy to sit? The puppy has no desire to sit. The puppy wants to frolic, run, play with toys. The last thing a puppy wants to do is sit. It's pretty much the same trying to teach students English.
