The teachers' and students' conversations were collected by means of audiotapes, observer comments, interviews, and fieldnotes. The results of this study indicate that the two ESL teachers did make considerable efforts to build a sense of community and trust with the other class members. For instance, teacher-fronted physical layout and power mismatch social structure in the traditional classroom have been adapted to cater for the students' affective state to reduce the threat of the learning situations and facilitate the students' language learning. However, the two ESL teachers differed in the degree of the positive-politeness strategies being employed, depending on their perception of the appropriate social distance in the classroom.禮貌策略社會距離英語教學語言使用內聚力Politeness StrategySocial DistanceEnglish TeachingLanguage UseSolidarity
