Many studies claimed that teachers are influential in classroom from the perspective; the human beings present in the classroom interact in a complex context to which students are susceptible in many aspects of learning. Especially in language classrooms, teachers are assumed to be more important and influential, which means that a teacher can play a greater part in helping the students to learn the language. Thus, it is worthwhile to focus on teachers in the classroom. The purpose of this study is to explore what two effective ESL teachers do in the classroom. Three different qualitative techniques were used and some salient findings emerging were used as themes. For data, the teachers" teaching was observed in class and they were interviewed outside of class. Students" responses to the teachers" behavior through written diaries and interviews were gathered to triangulate the data, which helped to yield more valid and comprehensive viewpoints. This in-depth examination of the two teachers allows us to better understand teacher roles in terms of encouraging students" better learning behavior in the classroom. It was found that, besides the two teachers" technical attention to teaching purposefulness, their attention to affective factor seems to be also effective.

Frequent interactions between teachers and learners take place in cyber education. It was found that tutors in cyber education play important roles in interactions. This is to acknowledge the characteristics of cyber education by watching and analyzing the interactions between learners and tutors that performed in the course of “cyber English writing class” of a cyber university. The main tools of interactions, e-bulletin board and e-writing assignment board have been quantitatively and qualitatively analyzed. In order to learn whether the degree of the learners’ participation influences the degree of the learners’ achievement, a correlation analysis between the two variables was conducted. A questionnaire was also conducted to learn how the learners respond to tutors’ feedback in their interactions. This study also investigated any differences of the attitude and satisfaction degree in a cyber writing class according to the learners’ participation degree. It was found that the degree of the learners’ achievement and the learners’ participation are most correlated especially when the learners are in the medium level of the academic ability. Also, the learners generally think the tutors’ feedback gives to them positive influences.
