A convective circulation box was redesigned after analyzing reasons why adolescent elementary school students could not derive a convective circulation concept from the convection circulation box experiments. Even though students were in the formal operational period of Piaget, the adolescents felt difficult to understand a concept of the natural phenomena they have never seen before. Thus, we designed a method to help students increase their scientific understandings about the concept through developing a miniature convective circulation box. Findings indicated that an application of redesigned convective circulation box in the classroom experiment significantly increased the students' understanding about the convective circulations of land and sea breezes, and as well as their participation in the activities. In addition, the redesigned convective circulation box motivated students to develop their scientific thinking skills by allowing them to decide where to put visible incenses inside the box and to directly observe the smoke currents circulation formed accordingly. Redesigning and using a convective circulationbox as a miniature of natural phenomenon helps students avoid having misconceptions. The biggest merits of the box are that it is observable in all directions, it provides much clearer convective circulations comparing to the extant box, and it requires low production costs.

The purpose of this study was to provide useful information for teachers by analyzing mathematical communication emphasized through 'exploratory activity' and 'story corner' in elementary textbooks based on the revised curriculum. Two classrooms from the first grade and second grade respectively were observed and videotaped. Mathematical communication of each classroom was analyzed in terms of questioning, explaining, and the sources of mathematical ideas. The results showed that only one classroom focused on students' thinking processes and explored their ideas, whereas the other classrooms focused mainly on finding answer. Particularly, this tendency often appeared when implementing 'story corner' than 'exploratory activity'. The reason for this was inferred that teachers were not familiar with teaching mathematics in stories and that teachers' manual did not include concrete questions and students' expected responses. This paper included implications on how to promote mathematical communication specifically in lower grades in elementary school.

In this study, we investigated students' behavioral characteristics in the process of and their responses to scientific creativity activities developed based on the three steps of learning model (Park, Park, & Lee, 2008) and scientific creativity model (Park, 2004). Students' responses were obtained by questionnaire, effectiveness of learning materials was explored by comparing students activities before and after the second step, 'Guide', and various characteristic behaviors were obtained through video-recording of their activities. As results, students answered that even though the activities were a little difficult, the activities were nonetheless interesting to them, and they wanted to do the activities more completely, and wanted them in future courses. It was also found that the second step activity was helpful in improving students' divergent thinking. Finally, from the findings about various students' behavioral characteristics, some practical recommendations for more effective teaching of scientific creativity were suggested.

STEAM is a multidisciplinary education program which intended to promote creative thinking by combining studies in the arts and STEM(Science, Technology, Engineer, Mathematics) fields. STEAM education can bring out creativities in students through educational activities of integrating and combining diverse studies. In this research, we integrated the educational elements of science, technology, engineering, mathematics, and arts using robots and then developed an educational program that raises the creative and character (focused on collaboration and communication) of students in a more fun and effective way. Using our developed educational program, we taught 6th grade students of an elementary school located in Seoul. As the result, most of students were found to be enhanced in their creativity and character after participating in the STEAM-based programming education course.

I conducted a pretest on the students' preference before I incorporated Cooperative learning in five classes of second grade students, at a girl's middle school which is located in Gimje city. After ten weeks of Cooperative school work, the students took a post test with the same questions as the pretest. The result of this method greatly impacted on the change of students' scientific preference. It means that the students showed their positive awareness of and the participation in the science class in comparison with the classes before they were taught this new style of education. However it is difficult to distinguish the differences of their scientific attitude on the recognition about the scientists and the habit which they think scientifically. This resulted from a short period of ten weeks of learning which is not sufficient to carry out the study strategy effectively. Surveys of the students on Cooperative learning indicates that the middle level students prefer this method unlike the higher or lower level. I am convinced that they can learn from the students of higher level and are able to help the lower level with the interaction through Cooperative learning.

The purpose of this study is to explore teachers' responsive moves that affect students' argumentation practices, and to propose responsive teaching strategies in argumentation-based science classroom. Two teachers, who have not implemented argumentation in their classes, and 57 students, participated in this study. We recorded and transcribed their classes and interviews for the analysis. According to grounded theory approach, we categorized the teachers' responsive moves as focused on either structural or dialogical aspects of argumentation, and qualitatively analyzed their responsive teaching practices in classes. We discovered that the teachers mostly responded to structural rather than dialogical aspects of argumentation, particularly during the students' small-group discussions. This was mainly due to their instructional goals, which focused on the structural aspect of argumentation, and the limited time available for supporting small-groups. Regarding the structural aspects, those responsive moves that explored the students' thinking or facilitated their reasoning helped them to share their thinking and justify their arguments further with recognition of learning goals in the argumentation activities. Regarding the dialogical aspects, which were seen mostly in whole-class discussions, the moves that underlined similarities and differences between arguments, facilitated the sharing of a small-group's arguments with the entire class, or asked a specific student to evaluate the arguments were notable. These moves supported clarification of various small-groups' arguments, which led to reconstruction of coherent argument through evaluation and rebuttal of these arguments, consequentially facilitating dialogical interactions. Based on these results, we proposed responsive teaching strategies in an argumentation-based science classroom.

학생들이 실세계와 수학적 세계사이를 연관시켜 사고하고 해석하는 방법 및 실제 문제를 해결하는 일반적인 전략의 방법론의 하나가 수학적 모델링(Mathematical modelling)이라고 볼 수 있다. 한편, 수학 교수 ${\cdot}$ 학습 과정에서 구체적인 조작 활동을 통하여 학생 스스로가 지식을 ‘구성(construction)’ 할 수 있도록 해 주어야 한다는 구성주의적 사조가 대두되고 있는데, 본 논문에서는 구성주의적 관점에서 수학적 모델링을 통한 수학 교수 ${\cdot}$ 지도를 위한 활용 방안을 한 예시를 통해서 고찰해 보고자 한다.

In this study, we developed tasks including cognitive scaffolding for students to explain scientific phenomena using valid evidences in science classroom and sought to investigate how tasks influence the development of small group scientific argumentation. Heterogeneous small groups in gender and achievement were organized in one classroom and the tasks were applied to the class. Students were asked to write down their own ideas, share individual ideas, and then choose the most plausible opinion in a group. One group was chosen for investigating the effect of tasks on the development of small group argumentation through the analysis of discourse transcripts of the group in 10 lessons, students' semi-structured interview, field note, and students' pre- and post argument tests. The discrepant argument examples were included in the tasks for students to refute an argument presenting evidences. Moreover, comparing opinion within the group and persuading others were included in the tasks to prompt small group argumentation. As a result, students' post-argument test grades were increased than pre-test grades, and they argued involving evidences and reasoning. The high level of arguments has appeared with high ratio of advanced utterances and lengthening of reasoning chain as lessons went on. Students had elaborate claims involving valid evidences and reasoning by reflective and critical thinking while discussing about the tasks. In addition, tasks which could have various warrants based on the data led to students' spontaneous participation. Therefore, this study has significance in understanding the context of developing small group argumentation, providing information about teaching and learning context prompting students to construct arguments in science inquiry lessons in middle school.
