  • 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.

  • 비형식교육의 장인 과학관은 전시물과 그 전시물을 설명한 판넬 등을 통하여 교육적 기능을 담당한다. 비형식 교육의 중요성 때문에, 과학관 전시는 전시물과 내용이 관람자와 교감하고 상호작용해야 할 뿐만 아니라 관람자에게 설득적으로 구성될 필요가 있으며, 하나의 공간에서 학습과 휴식이 어우러지면서 즐거움을 제공할 수 있어야한다. 이러한 과학관 전시의 요구사항을 충족시키기 위하여 가장 우선적으로 도입할 수 있는 방법이 스토리텔링이다. 스토리텔링은 '이야기하다'로서 관람객들에게 흥미 유발의 기능을 가지며, 그 효과가 단순 나열식보다 훨씬 크다. 하지만 스토리텔링기법에도 지식과 정보량에 있어서는 단점이 있다. 이것을 보완하기 위한 한 방법으로 전시물 설명에 논증 기법의 도입이 대두되고 있다. 즉, 거시적인 관점에서는 스토리텔링을 이용한 하나의 스토리를 도입하는 한편, 미시적인 관점에서는 논증의 구조를 따른 설명문을 이용한다면, 관람객들에게 흥미와 함께 지식과 정보를 모두 줄 수 있다. 이 연구에서는 논증과 스토리텔링의 조화된 결합을 통해 과학관의 전시를 재배열하는 작업을 수행하였다. 거시적인 관점과 미시적인 관점에서의 점검기준으로 영국의 자연사 박물관과 국립과천과학관 자연사관 우주와 지구관의 전시물의 구조를 분석 하였다. 그 결과 영국의 자연사 박물관과는 달리 국립과천과학관의 전시물은 스토리 내용, 설명문의 내용, 체험위주의 전시물이 부족하였다. 따라서 현 과천과학관의 전시물에 대해 스토리텔링과 Booth 등(2008)과 Lawson(2003)의 논증과의 조화를 도입하는 것이 바람직하다.

  • The research reported in this study focused on an analysis of argumentation in the inquiry discourse among pre-service science teachers. For about 3 months, 7 groups of 24 pre-service science teachers participated in an open-ended inquiry and performed 10 inquiry discourses. All discourses were collected by video-recording and transcribed. To analyze features of argumentation discourse, analytic tools derived from Toulmin's argument pattern and cognitive argumentation scheme were applied to discussion transcripts. The results were as follows: First, the order of frequency in the analysis of 'meaning unit' was 'claim-warrant-data-rebuttal-backing.' Second, the order of frequency in the analysis of 'dialogue unit' was 'CW-CD-CDW-CWR-CR'. Third, more rebuttals were found than other discussions. Fourth, the second argumentative discussion showed a higher level than the first.

  • The purpose of this study was to investigate how the argumentations were affected by the students' characteristics in the small groups. The level of self-concept and science related attitude were examined to the eleventh grade high school students in Daejeon city, and the twelve students were participated for this study. The participants were divided into homogeneous groups and heterogeneous groups. The argumentations under the condition of the interpretations about the experimental results in each small group were recorded by VCR. The recorded data were transcribed, then argumentation levels from transcripts in each small group were analyzed through Mitchell's parameters of argumentation. The results of this study were that the group which had higher level of both self-concept and science related attitudes achieved higher level of argumentation. Therefore, it is necessary for teachers to induce students to ask questions and present activities appropriately in order for those who have low self concept and science related attitudes to participate in argumentation.

  • The science education reforms put the emphasis of scientific literacy, so that students can understand how scientific knowledge is constructed through scientific inquiry at schools. However, scientific inquiry at schools has a problem as a cookbook system without the opportunity of developing argumentation, where students could understand how they use evidence to support their theory or vice versa. Teachers are supposed to understand the basic elements, purpose, and definition of scientific inquiry to implement authentic scientific inquiry at schools, then develop the instructional strategies of providing the opportunity of scientific argumentation to meet its needs.

  • We agree with Hanna and Jahnke's assertion on the use of arguments from physics in mathematical proofs and analyze their educational example of the use of arguments from physics in the proof of the center of gravity of a triangle. Moreover, we suggest practical models for the center of gravity of a triangle for the demonstration in a classroom. Comparing with the traditional mathematical arguments, the role of concepts and models from physics in arguments from physics will be clearly pointed out. Also, the necessity for arguments from physics in the classroom will be discussed in this paper.

  • The purpose of this study was to analyze the level of evidence used in gifted elementary students' argumentation. The subjects were 15, 5th and 6th grade students selected in the Science Education Institute for Gifted Youth in K University. After the argumentation task was given to students 2 weeks ago, the students grouped themselves in the affirmative and negative and took part in a debate for 2 hours. Their argumentation process was observed, recorded and transcribed for analysis. Transcribed data was given a Protocol Number according to priority and was examined to find out what were the characteristics when students participated in the task. The evidence used in argumentation was graded from level 1 to level 6 according to Perella's Hierarchy of Evidence and the rate of frequency classified by the level was expressed in graph. Students used Level 1- Level 2 evidence above 50% without for or against task. They had weak argumentation making use of low-level evidence such as individual experience, opinion and another person's experience rather than objective evidences. On the other hand, students commented on the lack of opponent's evidence when they could not trust an opponent's evidence. If one team asked the other to present more evidence but could not, they disregarded the question and turned to another topic. And in cases where the opponent team refuted with evidences of high level, the other team just repeated their claim or evaded the rebuttal. The students tended to complete the argument without the same conclusions with some interruptions. The results show that we need an educational programs including scientific argumentation for science-gifted elementary school students.

  • study was to explore the patterns and the characteristics of students' interactive argumentation in the middle school science classes. The data were collected by observing and audiotaping the small-group discussions and the transcribed data were analyzed through the lens of Toulmin's argument frame. As the results, the three argumentation patterns, which could be combined different ideas with or without their warrants, were presented. In the first pattern, the argumentation including the claim and its warrant without any different ideas, the students argumentation did not have any conflict with each other in the discussions. In the second, the argumentation of different ideas without their warrants, the different ideas did not affect the claim. In the last, the argumentation of different ideas with their warrants, the students elaborated the claim through collaborative argumentation in search for the warrant. To understand and improve student discussions in the science classrooms, conclusion and implications were discussed based on the results.

  • In this study, we analyzed the types of rebuttals in the argument structure of learning contents in lesson plans constructed by Earth science preservice teachers, and then we explored examples of how they responded to resolving the rebuttal. As a result of analyzing preservice teachers' assignments, discussions, and interviews collected during a total of 20 hours of classes and group discussions for 5 weeks, all 5 types of rebuttals suggested by Verheij (2005) were identified. Through the data analysis, a total of 18 rebuttal cases derived, and these cases were classified into 3 types according to how preservice teachers solve the rebuttals in class. The conclusions and implications based on the results are as follows: First, this study provided empirical data that the thinking process of validating core elements of argumentation and processes of argumentation is actively taking place in preservice teachers' lesson planning using the argument structure, and expanded the scope of application of argumentation in science education research. Second, the argument structure of learning contents should be used to help teachers to come up with strategies to induce students' curiosity and devotion to learn science contents. Third, preservice teachers should have the opportunity to think about the nature of science, including the variability and uncertainty of scientific knowledge when they discover rebuttals and develop solutions to them. Based on these conclusions, implications and suggestions for science education and further research were suggested.
