Teachers have the power to change their students' lives for the better, therefore teachers should be armed with some skills to be effective. Reflective teaching as one of these skills empowers teachers to observe and evaluate themselves. Although research on reflective teaching has a long tradition, little is known about whether it could be a significant predictor of language teacher immunity and work motivation as two important factors determining the success or failure of teachers, particularly in English as a Foreign Language (EFL) context. Thus, the present study aimed at examining the possible association among reflective teaching, language teacher immunity, and work motivation through path analysis. To this end, English Language Teacher Reflective Inventory (ELTRI), Language Teacher Immunity Instrument (LTII), and Multidimensional Work Motivation Scale (MWMS) were administered to 320 Iranian EFL teachers. Data analysis revealed that teachers with higher reflective teaching practices are more immunized and motivated. Moreover, the significant role of language teacher immunity on work motivation was discovered. The implications of the present study may shed new light on the significance of incorporating reflective approach into teacher development programs as a core subject.
