摘要：The purpose of this study was to investigate whether self-concept of EFL teachers influenced their effectiveness in teaching English as a foreign language, as perceived by both teachers and students. The study involved 275 EFL teachers and 88 senior high school students in South Sumatra. Variables of education, teaching experience, and age were analyzed using multiple regression analysis, and specific hypotheses were tested to see whether the addition of the other independent variables could add to the effectiveness of the teacher. The results showed significant relationships between self-concept and all the four factors used to define teacher effectiveness. The combination of self-concept and experience serves as the first salient factor influencing the four factors of teacher effectiveness in addition to self-concept alone. Education was also found to be a factor which influenced teacher effectiveness.
