Abstract
In the conversation, elementary level learners often use strategy of "Moo Ichido Ittekudasai" to make the other person to repeat phrases or sentences, when they didn't get what he/she have said. This presentation shows that, through analysis of phone conversations between elementary level learners and native Japanese speakers, this strategy might be less effective for extracting some appropriate assistance from conversational partners than learners expect, despite high reliance by them, and also discusses the necessary conditions under which this strategy works effectively for carrying out smooth communication.
