After pre-service teachers become teachers, traditional patterns of classroom discourse which they had experienced as students affect their classroom discourse implicitly. For this reason, it is needed to get a new insight for evaluating and reflecting a teacher's classroom discourse. In this study, I analyzed the information flow of science classes of pre-service elementary school teachers. The finding showed that teachers' organizational skills for students' information made advanced science classes by maintaining discourse cohesions. And the findings also showed a way how to analyze, evaluate or reflect science classroom discourse. This trial could contribute to find out the characteristics of teachers' science classroom discourse and show the directions to them how to change their classes beyond impressionable evaluations for their science classes.

This study explored how teachers and students in different countries discursively interact to build 'Classroom Science Knowledge' (CSK) - the knowledge generated situatedly in the context of the science classroom. Data came from publicly released $8^{th}$ grade science classroom videos of five nations who participated in the Third TIMSS (Trend in International Mathematics and Science Study) video study. A total of ten video-recorded science lessons and their verbatim transcripts were selected and analyzed using a framework developed by the researchers of the study. It was revealed that a range of discourse modes were utilized and these modes were often sequentially connected to build CSK in the science classrooms. Although dominant discourse modes and their sequences varied among different lessons or different countries, the study identified three salient patterns of science classroom discourse: teacher-guided negotiation and the sequences of exploring - building on the shared and retrieving - elaborating. These patterns were found to be different from the discursive features commonly witnessed in the community of professional scientists and interpreted as implying the existence of unique epistemic cultures shared in science classrooms of different countries. Further studies are suggested to reveal detailed characteristics of these epistemic cultures of science classrooms, as well as to confirm whether any cultural traits inherently shape the differences in science classroom discourse among different nations.

This study aims to provide a cornerstone for 'Pedagogical Discourse Analysis' by connecting linguistic theory to science education practice. Pedagogical Discourse Analysis (PDA) focuses its attention on finding educational implications beyond description on classroom language. This study is specially aimed at PDA in terms of the textual aspect, which has not sparked interest in science classroom discourse. For this, we supposed that the framework of PDA composed of two axes: 'thematic flow' and 'information flow'. We presented a case of science classroom discourse in terms of PDA to investigate opportunities in its potential and utilities. This trial crosses the line of traditional science classroom discourse analysis, which has been inclined to linguistics theory. It will also suggest a new horizon for science classroom discourse in an educational context.

This is a descriptive study to identify patterns of teacher questioning discourse. Transcripts from Korean secondary science classrooms were examined while extensive review of literature on classroom discourse was carried out. When it is assumed that teacher questioning discourse can be categorized into different patterns by considering together the apparent exchange structures and pedagogical functions, various patterns of teacher questioning discourse were revealed. Although most patterns found illustrate the centrality of the teacher, a few of them are considered alternatives to the typical IRE discourse. A framework for classifying teacher questioning discourse is suggested and its implications for science teacher education and future research discussed.

This study engages in the features of interaction in elementary school mathematics lessons as reflected in the class discourse. 28 pre-service teachers documented the discourse during observation of their tutor-teachers' lessons. Mapping the interaction patterns was performed by a unique graphic model developed for that purpose and enabled providing a spatial picture of the discourse conducted in the lesson. The research findings present the known discourse pattern "initiation-response-evaluation / feedback" (IRE/F) which is recurrent in all the lessons and the teacher's exclusive control over the class discourse patterns. Hence, the remaining time of the lesson for the pupils' discourse is short and meaningless.

The purpose of this article was to a) identify how preservice teachers conceive feedbacks and subsequent classroom discourses, and b) compare them with those in reform-oriented mathematics classroom video for mathematics teachers' professional development about classroom discourse. This article analyzes feedback patterns and subsequent classroom discourses in preservice teachers' imaginary classroom scripts (lesson plays) and compares them with those in the reform-oriented classroom video dealing with the same teaching situation. Most of the preservice teachers' feedbacks focused the evaluation of students' responses and transmission of meaning (univocal function), whereas the teacher's feedback in the reform-oriented classroom allowed the whole class to validate or challenge the answers, thereby facilitating students' generation of meaning (dialogic function). The comparison analysis between the univocal discourse in a preservice teacher's lesson play and the dialogical discourse in the reform-oriented classroom video shows that teacher feedback serves as an important indicator for the main function of classroom discourse and the levels of students' cognitive participation, and also as a variable that determines and changes them. This case study suggests that to improve the quality of classroom discourse, preservice and in-service teachers need experience of perceiving the variety of feedback patterns available in specific teaching contexts and exploring ways to balance the univocal and dialogical functioning in their feedback move during the teacher training courses.

The purpose of this study is to analyze classroom discourse in the math classroom of middle school in China, which has a unique math classroom background of entrance examination for high school. To this end, this study analyzed teacher question statistics and episodes by teacher question type as starting speech in mathematics classroom discourse, and five IRF subtypes were especially identified by class discourse structure analysis. The data were analyzed focusing on a total of 15 transcripts of math classes recorded by three math teachers at H School in Guiyang, Guizhou Province, China, and written interviews of teachers. According to the results of this study, an average of 20 teacher questions were observed for each class, and the teacher question type was classified into confirmation question (understanding confirmation question, explanation request question, and double check question) and information question (information presentation question). In addition, according to classroom discourse analysis, the IRF discourse structure was divided into fragmentary evaluation, evaluation+reason, evidence of explanation, evaluation+student response re-statement, guidance on other thoughts or solutions, and student answer correction or teacher opinion presentation.

The present study aims to examine how the roles of teacher and learners affect the repair patterns of both teacher's and learner's utterances in English as a second language (ESL) classroom discourse. The study analyzed beginning ESL classroom discourse and found that the structure of repair seems to be greatly influenced by the roles of participants in a second language classroom. The teacher's repair work was mainly characterized by self-repair. In contrast, learners' repair sequences were predominantly characterized by other-repair. More specifically, self-initiation by the learner of the trouble source was cooperatively completed by the teacher and the other learners. Other-initiated and other-completed repair was the most prevalent form in the current classroom data, which was carried out by the teacher in both modulated and unmodulated manners. When the trouble sources were mostly concerned with the learners' problems with linguistic competence and information presented in the textbook, other-repair took place in a modulated manner (i.e., recasting and prompting). On the other hand, when dealing with learners' errors with factual knowledge, other-repair was conducted in an unmodulated way (i.e., 'no' plus correction).

This paper, based on a qualitative ethnographic study among college of education students, examines the online interactional processes surrounding academic discourse socialization. Data for this paper come from a larger study of an academic classroom community of graduate students and their instructor. In this study, I looked into the ways computer-mediated communication (CMC) contexts factor into graduate students' academic literacy experience in a graduate classroom, therein enculturating them into their new academic community. I focus on cases of nonnative graduate students in a content course in the department of educational psychology at a large southwestern university in the U.S. I explore the agency of the focal participants in terms of the roles they played in the classroom discourse highlighting the dialectical and interactional perspective of academic discourse socialization. This paper focused on the construction of varied participant roles of the focal students. It further examines student reactions and responses to these constructions during synchronous CMC activity.

This study analyzed the classroom discourse between teacher and students based on the Mehan(1979a)'s theory to examine the characteristics of the classroom discourse between teacher and students in high school statistics class. The results of this study on the structure of class showed that the statistics class in this study adopted knowledge transmission-oriented teacher-led class in which the framework of introductiondevelopment- arrangement, which is Mehan's basic 3 stages, is clearly represented. The results of examining I-R-E sequence showed that $I_T-R_T$ structure, in which the teacher asks questions and the teacher talks about the answer, frequently appeared. And the statistics class in this study was monological class in which students hardly participated. Through these results of this study, it was found that teacher should form the statistical context, in which students can participate in discourse, and build discourse learning community and induce argumentational discourse through metaprocess elicitation.
