I admit...sometimes I also get frustrated teaching ESL.
Whenever I correct a student's bad habit in learning ESL, often, I get this reply: "But Teacher, this is how we learn English in our country."
I often tell my students that English is not a very difficult language to learn. These students, who first had their English lessons in their own countries, just make learning ESL very difficult by memorizing all grammar rules there are in their books, and by memozing all the definitions of words. Well... they were trained that way.
I guess the number one hindrance that these students have to overcome is their unwillingness to try another method of learning English. They often insist on practicing the method they learned back home.
I often use this logic: Do you really expect to make another hole if you keep on digging the same hole? Do you really expect to produce a different result if you keep on doing the same method? If you insist on doing your own method in learning ESL, then what's the point in coming here to learn ESL?
