This study aims to examine the development and learning process of the argumentative abilities in elementary school students with regards to learning science. Toward this end, the SSI argumentation education program was implemented in conjunction with the science curriculum for sixth-grade students across 10 months. In this process, the scoring criteria in terms of formal and content aspects were developed and used to assess their argumentative text analysis and expression abilities. The results were as follows: First, the type of SSI influenced their ability to analyze argumentative texts. However, their formal and content aspects improved as learning progressed. Second, with regards to the formal aspect associated with the ability to express argumentative texts, reasons were initially most frequently cited. Over time, incorporating evidence to support these reasons and the use of rebuttal also increased. Third, in terms of content aspect, the level of use of all elements increased as learning progressed; however, level of acknowledgments and rebuttal elements exhibited a relatively slower progress. In summary, ability of the students to analyze and express argumentative texts improved as they increasingly gained experience in learning about argumentation. The study deduced that elementary school students can develop their argumentative abilities through appropriate learning support, such as teacher feedback, along with implementation of the SSI argumentation education program over an extended period. Based on these results, the study proposes the development of SSI materials and incorporation of SSI argumentative writing in the science curriculum.

The cultivation of scientific literacy in recent science education can be improved by experiencing and understanding scientific inquiry by which scientific knowledge is formed. The National Research Council(NRC) released the Next Generation Science Standards (NGSS) including 8 practices of science that help students experience scientists' inquiry and subdividing achievement standards to perform 8 practices of science into by grade clusters. This study was intended to examine science inquiry activities included in 4 high school chemistry II textbooks developed by the 2009 revised curriculum using the 8 scientific practices and their achievement standards for 9th-12th grade. The science inquiry activities and the science practices included in the 4 textbooks were 173 and 678. The science practices included in the inquiry activities of 4 textbooks included the most ‘analyzing and interpreting data.’ The ‘engaging in argument from evidence’, ‘Obtaining, Evaluating, and Communicating Information’ were less than other practices. The ‘asking questions and defining problem’ and ‘developing and using models’ were not nearly included in the 4 high school chemistry II textbooks.

The purpose of this study was to develop instructional strategy for newspaper-based science writing and to examine the effect of its application. The target unit was 'change of weather' and 'a variety of gas' in the sixth grade of elementary school, and the teaching strategy was composed of 3 stages-writing including realistic, interpretative and comprehensive writing. The result of applying this strategy into actual classrooms was as follows. First, it was proven that the science writing strategy using newspaper articles actually helped improving science process skills of learners, in particular, integrated process skills. Second, this strategy for science writing changed the scientific attitude of learners positively. While they read the newspaper articles, their thinking became more elaborate and systemized, which seemed to serve to foster their openness, criticism, and perseverance. Third, the science writing strategy did not contribute to the improvement of learners' science study achievement. To improve the understanding of scientific concepts and principles of learners, it is needed that teaching program combines with argument-based activity organically. The above-mentioned findings show that this instructional strategy using newspaper articles can be applicable as one of effective methods in science writing.

The purpose of this study was to classify the types of scientific concepts by theoretical concepts and empirical concepts in physics, and to create cognitive conflict in students with logical statements and demonstrations, and to investigate conceptual changes. It seems that mechanics has much to do with the empirical concepts, and electromagnetics has much to do with the theoretical concepts. The condition of the instrument is intellegible, plausible, fruitful, and able to state and demonstrate. The instrument appropriate for these conditions was developed, which consisted of 6 items in mechanics and 6 items in electromagnetics, and conceptual changes were investigated. Structured interviews were conducted with 32 high school students to create cognitive conflict. We have elicited their ideas three times : pretest, posttest and delayed posttest. As the results of this study, demonstration method was more effective for conceptual change than logical argument method. In case of content areas, the misconceptions on mechanics concepts were changed more easily than those on electromagnetics concepts. In addition, the results of the study showed that the more cognitive conflict, the more the conceptual change was occurred.

The purpose of this study is to examine the effects which applies teaching program that search solution to prevent global warming in middle school gifted class. This program of total 10 class was theoretical and experimental class and the students presented after collecting the synthetic data about climate-change and roleplayed what they debated to firm their country's opinion about Kyoto Protocol. Finally, students as policymaker made mock Kyoto Protocol by discussion. Impression papers and images about climate-changes was made by students in last class. In discussion of making up mock Kyoto Protocol, developed and developing nations had an argument about carbon dioxide emissions because of their economic benefits. In the course of allocating mutual $CO_2$ reduction, they needed yield and negotiation among nations. Although they mainly took passive position about $CO_2$ reduction, atmosphere that all the country make greater effort for the future global environment was formed. Like this, students had more concepts over climate change by making mock Kyoto Protocol. And they could equipped global scientific literacy and responsibility by participating in social decision making process of solving global environmental issues.

The purpose of this study was to investigate the relation between the levels of cognitive conflict and students' conceptual change. In this study, 30 Korean high school students were selected from 450 10th graders by examining the pretest results. Two different strategies were used to induce cognitive conflicts in students, an anomalous or conflict situations; demonstrations and logical arguments against students' preconception. After arousing the students' cognitive conflict, the level of cognitive conflict was rated. Pretest, post-test and delayed post-test were administered to check the conceptual change. The tests consisted of 5 items in mechanics and electricity, respectively. Therefore, the demonstration method showed effective conceptual change, more than the logical argument method did. Students changed their conceptions more easily and frequently in the area of mechanics than in electricity. Students who showed higher levels of cognitive conflict indicated more positive conceptual change than those who showed lower conflict levels. 59 cases (56%) out of 105 who experienced high levels of cognitive conflict were changed into scientific conceptions one month later; however only 16 cases (35%) out of 46 who experienced low levels of cognitive conflict changed into scientific conceptions. Students who experienced higher levels of cognitive conflict showed higher rates of conceptual change. It could be concluded that designing instruction to induce cognitive conflict is a useful strategy to promote conceptual change.

The purpose of this research was to investigate the relationship between the change of beginning teachers' beliefs about a lesson and that of teaching practice and argument-based inquiry using science writing. Participants were three science teachers (A, B, and C) from different middle schools. Classroom observation and interview data were collected and transcribed for analysis. A Summary Writing test was also administered to examine whether there was an improvement in students' learning. The results indicated that the interaction between the teachers and their students developed, which is concluded as an improvement in the teaching practice. Teacher A and B also reported that teacher-student interaction had improved. Teacher A and C came to understand that argument-based inquiry using science writing classes constituted learner-centered instruction. The result from the Summary Writing Test showed the impact of the changes in teaching practice and in teachers' awareness of students' learning as well as produced meaningfully higher scores than compared groups on the rhetorical structure of all the specific areas in teacher A's school and on the scientific concept at B and C's schools.

This study is conducted to examine how epistemic reasoning and argument structures of students vary according to data sources used in the process of argumentation implemented in the context of inquiry. To this end, three argument tasks using first-hand data and three argument tasks using second-hand data were developed and applied to the unit on 'Nutrition of Plants' for first year middle school students. According to the results of this study, epistemic reasoning of students manifested during the process of argumentation and varied according to data sources. While most students composed explanations with phenomenon-based or relation-based reasoning in argumentation using first-hand data, all the small groups composed explanations that included model-based reasoning in argumentation using second-hand data. In the case of arguments including phenomenon-based or relation-based reasoning, students described only observable characteristics, with warrants omitted from arguments in many cases. On the other hand, in the case of arguments that included model-based reasoning, explanations were composed by combining the results of observations with theoretical knowledge, with warrants more apparent in their arguments.

School science practical work is often criticized as lacking key elements of authentic science, such as peer argumentation or debate through which social consensus is obtained. The purpose of this paper is to review the recent studies about the argumentation and to explore the conditions and the model of argumentative scientific inquiry, which is specially designed open inquiry in order to facilitate students' peer argumentation. For this purpose, a theoretical discussion for the argumentative scientific inquiry as the way of authentic inquiry in schools was developed. The conditions for argumentative scientific inquiry were found to be the following: multiple arguments, students' own claims, opportunities for oral and written argumentation, equal status of debaters, and community of cooperative competition. For these conditions, the argumentative scientific inquiry was organized into experiment activities and argumentation activities. During argumentation activity, students should be guided to advance written argumentation through writing a group report for peer review and oral argumentation through a critical discussion. Through the argumentation between groups and in group, the students' arguments would be elaborated repeatedly. The feedback from argumentation links experiment activities to argumentation activities. Hence, the whole process of this inquiry model is circular.

The argument about enlarging or limiting the function of the Korea Maritime Police. Agency (KMPA) has been and will be repeated. In this paper, the author highlights the internal and external issues facing KMPA, stemming partly from deficiencies of its struggles for advancement of the organization and partly from shortcomings of political support far it. And he urges KMPA to change the organizational culture for maintaining its identity and characteristics as a lead maritime agency by practising a scientific management system for maximizing cost-effectiveness of its administrative resources. In addition, he also suggests that KMPA adopt the Total Quality Management System for quality improvements in services and greater efficiency in its organizational structure to meet the future competition in the changing political and legal environment. he concludes by providing a 6-point vision statement for KMPA from the standpoint of favoring enlarging the function of KMPA.
