Abstract. The usefulness of code-switching as a teaching strategy in bilingual foreign language instruction is examined in this article. In order to improve comprehension, make difficult topics easier to understand, and foster a positive learning environment, it examines how teachers deliberately switch between the target language and the students' mother tongue. The usage of code-switching by students at primary, secondary, and high school levels is examined in this study. Additionally, it emphasizes the benefits and possible disadvantages of this method for learning a language. According to the research, code-switching can improve overall learning results, lessen anxiety, and increase students' comprehension when applied properly. However, the development of communicative competence in the target language may be hampered by an over-reliance on the original tongue. Therefore, the article recommends a balanced and purposeful use of code-switching in bilingual classrooms.
