Introduction:Recently, the concept of motivating students to learn has attracted greater concern from teachers of second and foreign language learning. They constantly seek to understand why some learners always go beyond what is expected of them, while others have difficulty achieving little of what is expected of them. Less motivated students who have psychological barriers feel that the task is too difficult, too hard and frustrating. Many researchers in the field of second language acquisition are interested in studying appropriate learning/teaching strategies to create an effective learning environment for successful and supportive language acquisition. Classroom interaction is therefore considered necessary and useful as a teaching strategy to improve learner motivation. The concept of classroom interaction plays an important role in learning a second language and improving learners' motivation. In fact, the considerable interest in classroom interaction has become an important factor for researchers in the field, as it provides the opportunity for the classroom community to develop its knowledge and for the teacher to focus more on its motivation. Understanding the role of classroom interaction in improving students' motivation to succeed in learning comes from a better understanding of its main types: teacher-learner interaction and learner-learner interaction, where are put forward the negotiation of meaning, the carrying out of activities, the exchange of ideas and the provision of feedback. Classroom interaction therefore requires the teacher to take into account that the learner must do most of the talking.
