This study describes, explores, and analyzes both Algerian secondary school learners and teachers’ use of Algerian Arabic in EFL classroom. It also aims at detecting the different situations that necessitated and still necessitate the implementation of the learners’ mother tongue in two public secondary schools in Algiers (Mohamed Hajress and Rabah Bittat secondary schools). The findings revealed that the language learners and teachers favor the use of L1 in ‘handful’ situations and believe it to be an aid for comprehending difficulties, checking learners’ understanding and clarifying ambiguities. They all wish it not to be used in giving instructions or explaining grammar. The findings also indicate that both foreign language learners and teachers agree that learners’ mother tongue should not be completely excluded from the language classroom.
