Studies on nonverbal behavior that accompanies speech are common; however, conversation-analytical studies focusing on nonverbal phenomena that can initiate repair on their own is very rare and most of them do not focus on the observations in this study, which are leaning forward and cupping the hand behind the ear. Accordingly, the focus of this study is leaning forward that can initiate repair without any verbal prompts to contribute to the gap in the literature. The data comes from Newcastle University Corpus of Academic Spoken English (NUCASE) data, specifically language learning classrooms which were analyzed in a qualitative and descriptive way from a conversational-analytical perspective. The observations showed that teachers and students created and oriented to the nonverbal moves as an initiator of repair. Also, the analysis of the data indicated that both leaning forward and cupping the hand behind the ear were observed to indicate a hearing problem. Leaning forward can engender repair initiation alone while cupping the hand behind the ear accompanies verbal moves and leaning forward. As for the sequential position, they follow a students' problematic turn but after a silence of a few seconds. So, the student produces a problematic turn, a few seconds lapse and then the teacher uses one of these nonverbal phenomena to indicate that there is a problem.
