The purpose of this study was to investigate the argumentation of middle school students during the argument-based inquiry. A total of sixty eight 8th grade middle school students participated in this study and they performed six argument-based inquiry programs. Data were collected from two of the latest programs by audio-recording and transcription of each group engaging in argumentation. The study findings showed that; first, the most frequent element of argumentation in the all of stages of the two programs was following order: 'claim' and 'request and response' and 'simple agreement'. The most active argumentation was showed at the designing experiments stage and the most inactive was showed at the generating questions stage. Second, as a result of analyzing the argumentation level for each stage of the argument-based inquiry, a high level of argumentation was shown at the claim and evidence stage, and a low level of argumentation was shown at the generating questions stage in the argumentation structure. As a result of the validity of argumentation, the validity of argumentation was the highest level in the claim and evidence stage.

The purpose of this study was to develop analytic framework for dialogic argumentation to show the context and flow visualizing interactions of argumentation, to be able to present quality of argumentation specifically. For this, we formulated a method of the argumentation diagram using feature of diagram simple and structurally visualizing interrelation between argument components, and then quantified quality of argumentation to argument level score on this basis. We have developed the learning material for argumentation about a vertical circular motion and used the obtained translations from applying it in developing the framework. We chose argument statements among full transcript and then coded as Toulmin's argument components, and these codes was effectively arranged and linked to show argumentation diagram. Results by argumentation diagram could be useful understanding of interactive argumentation context and the flow and present frequency, the combination of argument elements, rough qualitative level of argumentation. To quantify argumentation quality, we gave different scores to different link lines reflecting indication of argumentation quality like that diversity of argument component, justification, presence or absence of rebuttals. The process of identification of argument level is very simple, qualitative level of argumentation represented as concrete score could present various and concrete argument level. Developed analytic framework might contribute to argumentation research field, because it can present effectively dialogic argumentation result. Also, various analysis cases might guide designing an effective argumentation practice and circular motion learning.

The purpose of this study was to investigate middle school students' processes of argumentation in science lessons and to compare students' argumentation in different contexts (socioscientific context/scientific context). An argumentation-based teaching-learning strategy was used to enhance quality in students' arguments in science lessons. Data were collected from five lessons by video- and audio-recording eight groups of four students each engaging in argumentation. The quality and frequency of students' argumentation was analyzed using an assessment framework based on the work of Toulmin. The findings showed that: (a) there was improvement in the quality of students' argumentation; (b) there were no differences in the structure of argumentation and percentage of explanatory argumentation components as well as dialogic argumentation components in different argumentation contexts. The results of this study showed that students' argumentation can be enhanced with strategic argumentation teaching-learning.

This paper aims to theoretically discuss the re-conceptualization of the school geography curriculum towards global citizenship education. To achieve this goal, post-structural global citizenship is introduced as an alternative notion of global citizenship by revealing some limits of the existing postcolonial global citizenship studies for global justice. Based upon Carr's(1996) idea of curriculum typology, three major curriculum perspectives are theoretically evaluated to see if they implicitly or explicitly undermine the citizenship of global 'others' ethically and politically. Post-structuralist ideas are then suggested as an alternative approach. With reference to this standpoint, this paper concludes by providing practical implications for a more just school geography curriculum towards global citizenship.

This study examined the curriculum deliberation in the home economics historical literature of United State. Out of 13 literature, 9 were carried by academic federation or association and 4 were carried by individual authors. Starting from Catharine Beacher's Treatise on Domestic Economy to NASAFACS's National Standards for Family and Consumer Standards, the background of each document was introduced, curriculum contents organization was examined, and its implication was discussed. The results showed that home economics curriculum has been suggested being organised around key concepts in typical home economics areas throughout the history until the practical problem-focused curriculum organization based on critical science suggested by Majorie M. Brown in 1978. Regardless of the patterns of organization of curriculum contents, home economics pursue the common mission and aims of home economics. Another finding was that curriculum deliberation on the integration of curriculum contents was sought throughout the history.

The purpose of this study is to investigate the impact of argument-based modeling strategy using scientific writing on student's modeling ability. For this study, 66 students (three classes) from the 7th grade were selected and of these, 43 students (two classes) were assigned to two experimental groups while the other 23 students (one class) were assigned to comparative group. In the experimental groups, one group (22 students) was Argument-based multimodal Representation and Modeling (AbRM), and the other group (21 students) was Argument-based Modeling (AbM). Modeling ability consisted of identifying the problem, structuring of scientific concepts, adequacy of claim and evidence and index of multimodal representation. As for the modeling ability, AbRM group scored significantly higher than the other groups, AbM group was significantly higher than comparative group. The four sub-elements of modeling ability in the AbRM group was significantly higher than the other groups statistically and AbM group scored significantly higher than comparative group. From these results, the argument-based modeling strategy using scientific writing was effective on students' modeling ability. Students organized or expressed the model and evaluated or modified it through the process of argument-based modeling using scientific writing and the exchange of opinions with others by scientific language as argument and writing.

This study analyzed the relationship among the construct level of analogical reasoning, prediction and uncertainty, and the construction of an explanatory model that were produced during small group discussions for scientific problem solving. This study was participated in by 8 students of K University divided into 2 teams conducting scientific problem solving. The participants took part in discussions in groups after achieving scientific problem solving individually. Through individual interviews afterwards, changes in their thinking through discussion activities were looked into. The results are as follows: The analogy at the Entities/Attributes level was used to make people clearly understand the characteristics of certain objects or entities in the discussions. The analogy at the Configuration/Motion level that was produced during the discussions ensured other participants to predict the results of problem solving. The analogy at the Mechanism/Causation level changed the structure of problem situations either to help other participants to reconstruct the explanatory model or to come up with a new situation that was never been through before to justify the created mechanism and through this, the case of creating Thought Experiments during the discussions were observed. if looking into the changes of analogies, each individual's analogic paradigm during the discussions were shown as production paradigm, reception-production paradigm, production-reception paradigm, and reception paradigm. The construction and reconstruction of the explanatory model were shown in analogic production paradigm, and in the reception paradigm of an analogy, participants changed their predictions or their certainty.
