Teachers' conceptions about teaching are important driving and also interfering forces which might affect their actual practice and training. This research explores preservice mathematics teachers' conceptions of teacher discourse, through tasks analyzing and evaluating teachers' moment-to-moment discourse moves which occur in authoritative and dialogical classroom discourse. Some facets of the preservice teachers' conceptions were congruent with dialogical discourse: they criticized teacher's one-way communication and ignoring students' voices; they supported teacher's questions probing students' thinking and receptive attitude to ward students' wrong answers. However, some deep and subtle facets of their conceptions were more congruent with authoritative discourse rather than dialogical discourse: they positively perceived teacher's closed, information seeking questions that funnel students' thinking to the predetermined procedure; they emotionally resisted teacher's questions which might facilitate dialogical engagement by allowing students to judge mathematical correctness of ideas from their peers. Preservice teachers' conceptions of teacher discourse explored in this research provide useful foundations on which to build continuous and coherent teacher professional development programs about classroom discourse.

The purpose of this study is to specify the quality of I-R-E pattern and question-answer affiliation between students and teacher, depending on teacher's career. This study analyzes 6 classroom discourse texts of 6th grade science class. The results of this study are as follows. First, in the case of a newly appointed teacher, I-R-E pattern is appeared repeatedly. Second, in the case of experienced teachers, expended I-R-E pattern is appeared compare with a newly appointed teacher. Third, in the case of a newly appointed teacher, independence relational structure is appeared more repeatedly than other structures. But, in the case of experienced teachers, all kinds of question-answer structures - independence, parallel, insertion, and reorganization relational structure - are appeared more evenly.

Mathematical communication has been emphasized not only as the process of learning mathematics but also as the objective of mathematics education. However, little studies have been conducted with regard to what to consider and how to implement in the actual classroom for promoting mathematical communication. Given this background, this paper implemented a mathematics instruction in each of 2nd, 4th, and 6th grade classrooms in which specific learning objectives were considered to promote discourse-based mathematical communication. It then analyzed the degree by which such learning objectives were achieved and the linguistic interactions between the teacher and students in each classroom. This paper finally provided issues and suggestions for effective discourse-based instruction in mathematics classroom by analyzing similarities and differences among the three classrooms.

The purpose of this study was to investigate the epistemic process in elementary science classrooms by analyzing classroom discourse as a epistemic practice. Data came from four elementary teachers in the form of video-recordings. A total of 12 elementary science lessons were examined to reveal the discursive modes and sequences in which the teacher and students participated when they constructed and developed scientific knowledge during the lessons. Three representative discursive patterns were found in the elementary science lessons explored: (i) 'Retrieving-Retrieving-${\cdots}$' by which well-established scientific knowledge was retrieved repeatedly, (ii) 'Exploring-Building on the Shared' which allowed introducing new scientific knowledge based on the scientific phenomena explored by the teacher and students together through practical work, and (iii) 'Retrieving-Elaborating/Reformulating/Narrating' or 'Building on the Shared-Elaborating/Reformulating/Narrating' which expanded and strengthened scientific knowledge already learned. These discursive patterns were suggested as discursive-epistemic mechanisms employed frequently in the epistemic process in elementary science lessons and as a basis for defining epistemic cultures of science classrooms.

The language socialization approach states that novices are socialized into cultural norms through participating in routine, repeated interactional acts and sequences (e.g., Ochs & Schieffelin, 1984; Ochs, 1988; Schieffelin & Ochs, 1986a; 1986b; Watson-Gegeo & Gegeo, 1986). One of the cultural norms or dominant epistemological orientations in American culture is the tendency to avoid the overt display of power asymmetry in novice-expert relationship (Ochs & Schieffelin, 1984). This study examines how this cultural preference is reflected and encoded in ESL teachers' use of routine discourse patterns in corrective sequences. Eight hours of ESL classes taught by three Caucasian teachers born and educated in the U.S. were analyzed for the study. The analysis showed that the cultural tendency in question is keyed and indexed in the teacher's routine corrective discourse patterns in the form of various questioning, elicitation, and mitigation practices. Findings support that teachers' routine classroom discourse practices represent their cultural ideologies and transfer these cultural predispositions to second language learners and that they possibly socialize the learners into the target language-oriented beliefs.

Since there are differences in the content, structure and functions of interpersonal communication during the practice of school science classes, it needs to articulate the difference of the modality of pedagogical practice in order to understand science teaching in detail. These characteristics of science teaching can be investigated by further insightful analysis on language in the science classroom. In this study, classroom discourse language codes using Bernstein's code theory were analyzed in the case of a middle school science class on the unit of minerals. The discourse language code was identified by the value of classification, which revealed power relations to the contexts of discourse and participants of discourse. It was also identified by the value of framing, which showed hierarchical relation between teacher and students as discourse subjects, and discursive control on the initiative of discourse. The results addressed that six types of discourse language codes were constructed and that those language codes reflected diverse modalities of science teaching from student-centered instruction to teacher-centered instruction in relation to classroom discourse. The modality of science teaching according to the transition tendencies of discourse language code showed dynamic variations of 'controlled student-centeredness inducing teaching' - 'positional student-centeredness permissive teaching' - 'controlled students' participation permissive teaching' - 'controlled student-centeredness facilitative teaching' - 'student-centeredness enhancing teaching'. In addition, results released that discursively and hierarchically weak control of discourse is necessary for enhancing student-centeredness of science teaching. Moreover, teaching practice enhancing student-centeredness can be accomplished by the harmony of a teacher's perception of discourse language code and his/her orientation to constructivist teaching and student-centered teaching.

The purpose of this study was to examine the relations among mathematics teachers' beliefs, classroom norms and discourse, and equity issues in mathematics classrooms. In order to achieve this purpose, three teachers who work in the same school were analyzed. The analysis revealed that the participating teachers' beliefs about mathematics teaching and learning and about their students' abilities and motivation influenced the establishment of classroom norms and discourses that defined what students needed to do to be successful mathematics learners. Also, classroom norms and discourse affected the development of students' identity and power and the level of equity in the classroom.

This study aimed to analyze the characteristics of good science teachings regarded by preservice elementary school teachers. It also aimed to suggest a direction of peer teaching practice to help preservice teachers' professional development. Adjacency pairs were adopted to analyze the characteristics of good science teachings. The results showed that pre-service elementary teachers were accustomed to adjacency pairs. Almost of their discourse were organized by adjacency pairs. 'Question-Answer' and 'Request-Accept' were mainly used in science classes by pre-service elementary teachers. Based on the findings, the study suggested science teacher educators to provide chances to analyze exemplary science teachers' science class or chances to analyze their science teachings in terms of competence of science classroom discourse.

In this paper I attempt to survey on the theories of observation and analysis of mathematics classroom discourse. In order to discuss applicability of the theories I look at preservice teachers' observation of mathe-matics classroom and teachers' conception of mathematics lesson. In examining reports from preservice teachers' I identify how they understand mathematics lesson and how the theories can enhance their understanding. Not surprisingly, there are lots of obstacles for teachers to practice mathe-matics educational theories. 1 find some features of their efforts or attempts to overcome the obstacles in an attempt to gain insights into alternative ways of concep-tualizing the methods of observation and analysis through the interview and the discussion with teachers.

This study investigates English medium instruction (EMI) in an institution of higher education in Seoul, Korea to see whether this course creates cultural correction (reproduction of inequitable relations of power in EMI settings) or cultural continuity (opportunities for transporting students into a third space and enabling them to explore cultural diversity and to create new knowledge for themselves). A single site where EMI is carried out, a class on fairy tales and child education taught by a native English speaking professor, was chosen because it was hypothesized that the professor would display some of her unconscious dominant cultural orientation. The results of the study show that there more cases of cultural correction than there were of cultural continuity. Cases of cultural correction included lack of knowledge about the local context, fixing Korean classroom discourse as if it were American classroom discourse, and reproducing orientalism in the local educational setting. Cases of cultural continuity included using comparison to consider the cultural reality of the milieu, creating new knowledge for the local milieu, and learning as a dynamic ongoing process. Implications of this research are discussed including the important realization that EMI should be managed by subject specialists who are trained in language education and have knowledge of the students' needs and discourse in the L1 and in the local context.
