One of the most controversial issues in foreign language teaching and learning over many years has been the role of the students’ L1 in L2 target language education. While a monolingual approach prohibited the use of the target language in L2 classroom, researchers have reexamined the issues related to the use of students’ L1 through code switching in the L2 classroom since the 1990s. The results of these studies have shown that the L1, if used properly and judiciously, may serve important functions for the learning process and social environment of the classroom. The purpose of this study was a systematic literature review of this research for the preparation of a guidebook as to the functions, manner, reasons, and contributions of code switching as a part of 2L English language teaching.
