摘要:This study explored whether there was a relationship between the level of language proficiency and repairing conversation in English classes. For this purpose, sixty participants learning English as foreign language were divided into four coed classes, i.e., two intermediate and two advanced classes, and two sessions of each class were recorded during an academic term offered in a private language school in Mashhad, Iran. The cases of repair in the conversations of these learners were identified and transcribed separately for both groups during the term. They were then categorized based on the place of repair initiation and the type of repair completion. The frequencies of cases were then subjected to statistical tests conducted via the S-PLUS program. The results showed that both intermediate and advanced learners prefer self-repair over other repair. It was also found that they differ significantly from each other not only in the number of times they allow self-and-other repairs to occur but also in the frequency with which repair-initiations and repair-completions are combined. The findings are discussed within a foreign language context.
