Novice English as a foreign language (EFL) or second language (ESL) teachers' self-perception is highly affected by their belief of their language ability. This belief directly affects their self-efficacy as teachers, which in turn, has a negative effect on their teaching ability. This study explored the use of self-translation as a process that enables novice teachers to get a new sense of their language ability through bilingual experiences. Identifying oneself as bilingual has a positive influence on the teacher's self-perception, leading to a positive impact on their self-efficacy and confidence. Three groups of 30, third and fourth year EFL majors, experienced self-translation via narratives of personal experience during a one semester course and analyzed their language ability through these narratives. A mixed method approach was used for data collection. Quantitative data show a correlation between the participants' beliefs of bilingual teachers' abilities and their perception of their own teaching ability. Furthermore, a significant positive change was noticed in self-perception, bilingual identity, and self-efficacy. Qualitative data support this and indicate a higher comfort level as well as more confidence with language abilities after the self-translation experience, leading to a more positive self-perception of teaching ability and thus increasing self-efficacy.
