Student: Excuse me, Mr. Ma, I am doing a survey for a social study of English Teachers in our school. Would you mind answering a few questions?
Mr. Ma: No, not at all. What do you want to know?
Student: How long have you been teaching English?
Mr. Ma: 20 years.
Student: Wwa! 20 years! That’s almost as old as I am! What kind of mining have you had?
Mr. Ma: I graduated from a four-year-teacher’s college about 20 years ago. I learned both English and pedagogy during my college years.
Student: Have you been to an English speaking country?
Mr. Ma: Yes. Last summer I was awarded a study-abroad scholarship in Canada.
Student: What did you do in Canada?
Mr. Ma: A Canadian college ran a teacher’s training program for us Chinese teachers. We learned how to organize English classes. The program was very successful.
Student: What is your most significant accomplishment in teaching English?
Mr. Ma: One of my students won first prize in National Competition of English Skills five years ago.
Student: Competition of English Skills? What was that?
Mr. Ma: It was a competition that included speaking, listening, creating an English web page and writing English subtitles for drawings.
Student: That must have been very challenging.
Mr. Ma: Yes, I was very proud of my students. And I was very proud of myself.
Student: Are you bothered by any problems in your teaching?
Mr. Ma: Yes, of course, I am sometimes frustrated when I see the poor scores of my students in a class quiz or examination. Sometimes I don’t know how to help them move forward in their studies.
Student: What is your plan to help your students get better scores in the future?
Mr. Ma: I hope to try some new interactive ways of teaching in my next term.
Student: Thank you very much for answering my questions. I have learned a lot from this interview.
