Argumentation is a social and collaborative dialogic process. A large number of researchers have focused on analyzing the structure of students' argumentation occurring in the scientific inquiry context, using the Toulmin's model of argument. Since SSI dialogic argumentation often presents distinctive features (e.g. interdisciplinary, controversial, value-laden, etc.), Toulmin's model would not fit into the context. Therefore, we attempted to develop an analytical framework for SSI dialogic argumentation by addressing the concepts of 'discourse clusters' and 'discourse schemes.' Discourse clusters indicated a series of utterances created for a similar dialogical purpose in the SSI contexts. Discourse schemes denoted meaningful discourse units that well represented the features of SSI reasoning. In this study, we presented six types of discourse clusters and 19 discourse schemes. We applied the framework to the data of students' group discourse on SSIs (e.g. euthanasia, nuclear energy, etc.) in order to verify its validity and applicability. The results indicate that the framework well explained the overall flow, dynamics, and features of students' discourse on SSI.

The purpose of this study is to develop the workshop to improve teachers' questions considering the context of discourse. Four pre-service science teachers in the fourth grade participated in the study. Pre-service science teachers participated in the workshop. The characteristics of their reflection on the question considering the context of discourse were analyzed. Pre-service science teachers considered the types of questions they learned in the workshop during the reflection. But the affective domains of students were rarely considered. Whether the students respond was considered as an important factor of reflection. The questions were evaluated based on the frequencies. A single question without context was reflected on. Various PCK elements were not considered comprehensively. Based on the results, the practical implications to develop a program for improving teacher expertise related to the questions considering the context of discourse were discussed.

This study aimed to explore the patterns of college students' dialogic argumentation in the context of nanotechnology issues, and to compare these patterns based on their idiocentrism and allocentrism. Nanotechnology represents the characteristics of socioscientific issues in that it is widely used in various fields, but at the same time, it includes the likelihood of negative effects. 33 college students who enrolled in science-related course participated in this study. Participants were divided into idiocentric groups and allocentric groups based on the INDCOL scores, and they participated in group discussions on nanotechnology. All discussions were audiotaped and analyzed using the framework of discourse clusters and schemes. Results showed that participating students engaged in dialogic argumentation with the process of exchanging of individual perspectives, exploration of different perspectives, and coordination and negotiation; specifically, they spent most of their time in exploring different values and perspectives regarding nanotechnology. Results also indicated the differences in discourse clusters and discourse schemes between idiocentric and allocentric groups. Allocentric groups more often negotiated to settle on a group decision than idiocentric groups did, and discourse schemes in their negotiation process were slightly different from the ones in idiocentric groups.

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.

본 연구의 목적은 한국 현대시 텍스트가 독자에게 전달하는 시적 효과를 담화 텍스트 언어학 및 인지적 화용론의 관점에서 분석하는 것이다. 담화 텍스트 언어학은 텍스트의 언어 자료 자체보다는 이를 생산하고 수용하는 인지 과정에 주목하는 인지과학의 한 분야이며, 적합성 원리로 되는 인지적 화용론은 텍스트 언어학에서 규명하는 바 여러 인지적 조작 절차들의 심리학적 근거가 된다. 많은 인지적 책략 및 조작 절차들이 집약되어 있는 한국 현대시 텍스트를 인지 화용론적 관점에서 분석한 결과, 이제까지 모호하게 개진되어 오던 많은 시적 효과가 텍스트 언어학 및 인지적 화용론의 분석 장치들에 의해서 명쾌하게 설명될 수 있음이 밝혀졌다. 즉, 정보성의 격상 및 격하, 각별한 결속구조의 사용 및 그 수용 과정, 작가의 상황점검과 상황관리 과정에 의한 전국적 인지 패턴의 활성화 및 수정 등의 인지적 절차를 통해서 독자의 맥락이 수정, 확장되는 효과가 일어나고 바로 이것이 궁극적으로는 시적 효과를 낳는다는 점을 설명할 수 있다.

The purpose of this study is to examine the presentation of Korean grammar on the Korean grammar textbooks for foreigners. Through the results, this study suggests some examples of grammar based on the discourse and context. Since the communicative approach received much attention, some Korean language forms have been researched in the discourse and context. In that sense, we need to survey the grammars presented in the grammar textbooks. The expressions of Korean epistemic modality and discourse function, ('-지요, -잖아(요), -군요', '-기는 하다') in the grammar textbooks have been analyzed. These expressions need to be described with much contextual and situational information and presented in the discourse. However it is a little insufficient to supply a proper amount of information for Korean language learners. To overcome the deficiency, this study presents some situational and contextual information of certain language forms.

This study aims to look into the characteristics of argumentation in the task context of 'Monty Hall problem' at a high school probability class. As a result of an analysis of classroom discourses on the argumentation between teachers and second-year students in one upper level class in high school using Toulmin's argument pattern, it was found that it would be important to create a task context and a safe classroom culture in which the students could ask questions and refute them in order to make it an argument-centered discourse community. In addition, through the argumentation of solving complex problems together, the students could be further engaged in the class, and the actual empirical context enriched the understanding of concepts. However, reasoning in argumentation was mostly not a statistical one, but a mathematical one centered around probability problem-solving. Through these results of the study, it was noted that the teachers should help the students actively participate in argumentation through the task context and question, and an understanding of a statistical reasoning of interpreting the context would be necessary in order to induce their thinking and reasoning about probability and statistics.

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.

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 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.
