Abstract
Feasibility of maintaining an educational sustainable development (ESD) depends on exploring teachers’ concepts on their common practices in classroom settings. Speakers in multilingual contexts commonly switch their codes, languages, during their numerous social interactions. Nowadays, the phenomena, code switching, has expanded to cover any situation in which speakers switch from one accepted code into another. Through this perspective, various studies have been conducted to investigate different aspects of code-switching in EFL classrooms. The present study qualitatively investigated teachers’ perceptions on code-switching in their classrooms addressing two research questions, namely what types of code-switching EFL teachers were practicing in EFL classrooms and what were their perceptions on their code-switching. Four EFL teachers participated in the study. The analysis of the data collected through manual and electronic observations as well as structured interviews, indicated that intra-sentential and inter-sentential types of code-switching were practised throughout the classroom teaching processes. The main motives for resorting to code-switching were found to be EFL students’ lack of linguistic proficiency, keeping solidarity with the students and managing the classrooms.
