In literature on bilingual teaching, different perspectives exist for and against the use of first language (L1) in English as a Foreign Language (EFL) classrooms. There is a continuing matter of debate on whether L1 contributes to or precludes the learning of a second language (L2). Numerous studies have been conducted on this topic, but no clear consensus exists on whether L1 should be banned or its inclusion in EFL classrooms should be allowed. A significant body of literature has explored this phenomenon from teachers' perspectives, and an adequate number of studies have explored the phenomenon from the students' perspectives. However, few studies have identified the reasons for which students need such an inclusion. More importantly, no studies seem to have considered demographic variables that may directly influence students' perceptions of the use of L1 in their (L2) classrooms, that is; educational background and their language proficiency level. This study primarily investigated whether students' educational background and their L2 proficiency influenced their perceptions of the use of Turkish in their L2 classrooms as well as their perceptions and needs for the use of L1 in their classrooms. The study was conducted on a sample of 303 Turkish learners of EFL at English Preparatory School of European University of Lefke in Northern Cyprus. Data were collected using a questionnaire. Analysis of the data indicated that EFL students had high positive perceptions toward the inclusion of L1 in their L2 classes and that their perceptions were affected by their demographic characteristics. Students with lower level of L2 proficiency were also found to have more positive perceptions toward the use of L1. Furthermore, the particular issues where students needed L1 were also identified. Implications for language teachers and policy makers are discussed.
