Therefore, teachers must remain vigilant in how they use language. Bilingual teachers may often choose to alternate languages ​​for particular reasons or do so unconsciously. There are teachers who believe that code-switching should be avoided in English language teaching, while others perceive code-switching as a useful teaching strategy for understanding components of the target language which is sometimes English. Regardless of teachers' opinions on which aspect should be favored, it is crucial to study the reasons that influence code-switching by teachers in English language learning classrooms. This will help other educators better decide whether to include or exclude code-switching in the language teaching process.
