I believe students are human beings who deserve respect as individuals. Not every one can list five or six languages amog their academic accomplishments!
Like thousands of native English teachers, I believe in an open-ended, dialogic method in classes, person-to-person, or in small groups.
As I'm a writer and painter, and have taught courses on World Cinema, there is never enough time to end a class except at its organic closure. The clock in my class is a guide. Not acontrol!
Many former students return to my class for back-up sessions, and I have often flown abroad to take up supplementary tuition for students I hae known to be serious, but also good-humoured and playful. Language itself is gameplying, experiment, lunging in instead of being fearful or embarrassed. We all make mistakes even in our massive tongue. Communication is paramount. And so too is attention toward whomever happens to be speaking. If you have been frustrated in a class, then I'm sure you follow the spirit of my address on these matters.
Finally, I should say that I happen to believe that being on target in terms of the 'success' of individual learners is concerned, isn't half as conducive, playful, amusing and satisfying to instructor and students alike as is what good classes can affect in the course of a few weeks of English language tutelage, for both students and tutor!
All my students appreciate the bond that unites the professor and each and every student. Result? Cooperation = success.
