The experimental evidence evaluation of the 11th grade students(N:91) was investigated. Specially, the influence of students' ideas about optical phenomena and presented evidence types on their evidence evaluation, and the influence of students' ideas on their causal inference modes were investigated. After eliciting the students' ideas about shadow phenomena and conformity of their idea, the experimental results with a binary outcome were presented as the evidence. Then the students were asked to evaluate the evidence. Again students' ideas were elicited. Most of students had causal ideas such that the shape of object(96%) and the inclination of screen(75%) were causes of shadow shape, not the shape(70%) and color(92%) of light source. In the case of the shape of object and the color of light source, most students(70%) believed strongly their ideas. Most responses(80%) in the evidence were evidence-based, and 12% of them were theory-based. There was no significant difference of reponses types between students with causal ideas(81%) and students with non-causal ideas(78%), between covariable and non-covariable evidence. But in the case of non-causal ideas, covariable evidence was more likely to yield evidence-based reponses than non-covariable evidence. If students had preconcepts inconsistent(84%) with the evidence, they were more likely to make evidence-based responses than the students with consistent ideas (75%) with the evidence. Especially in the case perceptually biased evidence, this tendency was marked. In the case of covariable evidence, many students made inclusion inferences(40%) rather than uncertainty inferences(32%). In the case of uncertainty inferences(94%), students more likely to make evidence-based reponses than inclusion inferences(83%) and exclusion infernces(88%). In the case of inclusion inferences and exclusion infernces, students tended to make idea-based responses and distort the evidences. In conclusion, when the students evaluate the experimental evidences, their ideas influence the causal inference modes. Especially, according to the conformity of the preconcepts and logical relation of evidences, the inference modes are more strongly depended upon the preconcepts rather than evidences.

An enhanced understanding of the nature of scientific knowledge-what counts as a scientific argument and how scientists justify their claims with evidence-has been central in Korean science instruction. However, despite its importance, scholars are generally concerned about the difficulty of both addressing and improving students' epistemic understanding, especially for students of a young age. This study investigated Korean middle school students' epistemic ideas about claim, data, evidence, and argument when they engage in reading both text-based and data-inscription arguments. Compared to previous studies, Korean middle school students show a sophisticated understanding of the role of claim and evidence. Yet, these students think that there is only a single way of interpreting data. When comparing students' ideas from text-based and data-inscription arguments, the majority of Korean students barely perceive text description as evidence and recognize only measured data as evidence.

The purpose of this study was to investigate the effect of scientific argumentation on argument tasks with incorrect alternative ideas in elementary science classes. The subjects were 41 fourth graders of 2 classes in an elementary school. In the experimental group, argument tasks with pictures including incorrect alternative ideas were suggested in order to facilitate argumentation. Students were asked to perform argumentation with the component of claim, evidence, and reasoning. In the control group, textbook-based traditional instruction was used. The results showed that scientific argumentation activities on argument tasks with incorrect alternative ideas had positive effects on students' science achievement and science-related affective domains. The analyses of students' argumentation revealed that argument tasks with incorrect alternative ideas could facilitate students' participation and exposure of their preconceptions. It also led students to find and connect evidence to support their claims. In some cases, students had difficulty in making appropriate argumentation because of unclear experimental data and/or invalid reasoning. Educational implications were discussed.

For effective conceptual teaching (or teaming) of physics, it needs to know more information about students＇ ideas related to specific topics. The purpose of this study was to investigate 6th grade students＇ various ideas about the actions of force, especially＇ the situation where force is being acted＇, and＇ the situation where force is not being acted＇, through the analysis of their ＇Typically-Perceived-Situation (TPS)＇. The TPSs of 152 6th grade students were collected with a drawing-and-explanation type questionnaire, and their TPSs about the action of force were categorized by the background, the subject, the object, the action, and the result of action, etc. It was found that most of students＇ ideas about ＇force is being acted＇ were related to the situation where the impact by or on human body caused to the change of position in familiar everyday life scene. Thus their ideas were strong related to human body, including sensual factors such as ＇pain＇. And it also was found that most of students＇ ideas about ＇force is not being acted＇ were in a strong relation to familiar everyday life situations there is no change of position because force was not given by a human body, or energy was not supplied. Most students thought that force is similar to energy which should be supplied from outside or generated by itself. These results suggest that the teaching strategies focused on familiar everyday life background including sensual factors and human body need to be explored in conceptual loaming of physics.

Cultivating creativity is one of the goals in science education. Previous studies report that students use visualization while they solve the creative science problem and it looks helpful to make them think more. For this study three $6^{th}$ grade students were selected in the consideration of pre-test through the qualitative think-aloud method. The results show that even though students have many ideas in planning stage in problem solving, they appeared to visualize familiar and empirical ideas at first. So if teachers want to watch another creative ideas, they tended to give enough time to visualize many ideas. Students drew lines, circles, "X"marks to select or remove information during their problem solving works. They said these marks seem to be useful to understand question. However, removal marks sometimes turn out to block another chance to re-think. Also students did not have a chance to reflect what they did. It means that they lose the chance to do convergent thinking. The implications of this study include the importance of students' visualization works to facilitate their creative ideas and support their problem solving strategies. In this study, we discuss the meaningful messages for teachers who construct science classroom for creativity.

When modeling students' conceptual understanding, there are several different frameworks, among which are the alternative conception framework and the mental model framework, which converge to suggest a form of knowledge representation. However, little research has explained how they are different from each other and from memory. The purpose of this study was to develop a new mental model theory that integrates the different terminologies and their background theories, which refer to students' ideas not only in science education, but also in other research areas. For this purpose, at first, we compared different terminologies including alternative conception, p-prim, and mental models, and the underlying theories used for representing students' ideas in learning science. Through such comparison, we tried to find the relationship among them. We reviewed related literature and synthesized the results from both cognitive science (related research areas) and science education approaches, especially, Vosniadou's mental model theory. Based on reviewing previous studies, we have developed a preliminary mental model theory 'an integrated theoretical structure of mental models'. We applied the new mental model theory to interpret data on students' ideas about circular motion from our previous research. We expect our new mental model theory will help us understand how students form their own ideas in science from an integrated perspective.

실험활동은 과학교육에서 중요한 요소로서, 그 목적과 효과에 대해 많은 논의가 있어왔다. 그러나 이에 관한 연구결과는 회의적이며 그 이유 중 하나는 하나의 실험은 동시에 다양한 목적을 성취할 수 없으며, 교사와 학생들이 실험의 목적에 대해 인식하고 있지 않기 때문이라는 것이다. 그러므로 본 연구에서는 시험의 목적에 대한 중학생들의 인식을 조사하였다. 실험의 목적에 대한 중학생들의 인식을 알아보기 위해 '과학자들의 실험'과 '학교실험'의 두 가지 상황에 대해 서울 소재 중학교 1학년생 147명을 대상으로 실험의 목적에 대해 서술형으로 응답하도록 하였다. 응답을 분석한 결과, 학생들의 56.8%가 과학자들이 새로운 것을 발견하거나 발명하기 위해 시험을 하는 것으로 응답하였으며, 학교실험에 대해서는 82.9%의 학생들이 인지적 영역, 즉 교과서에서 배운 것을 이해하거나 암기하기 위한 것이라고 응답하였다. 성별과 성취도에 따른 응답비율의 차이를 조사한 결과 남학생들의 경우에는 사회적 유용성을, 여학생의 경우에는 개인적 즐거움을 더 많이 응답하였다. 과학자의 시험과 학교실험에 대한 인식의 상화관련을 조사한 결과, 과학자들의 실험이 이론을 증명하는 것이라고 생각하는 학생은 학교 시험의 기능도 유사하게 생각하였다. 마지막으로 학생들의 응답을 정성적으로 분석하였으며, 결론적으로 학생들은 실험에 대해 다양하고 적절한 인식을 가지고 있지 못하며, 학교실험에 대해 회의적인 태도를 보이기도 하였다. 이를 개선하기 위해서 교사는 시험의 다양한 목적에 대해 학생들에게 알려주고, 매 시험마다 그 실험의 목적에 대해 명확히 밝혀야 할 것이다.

This study aims to develop a scientific creativity task which science-gifted elementary students can conduct on a field trip to a botanical garden, and to analyze the results from conducting the task. For this, 38 science-gifted fifth-graders from the Science-Gifted Education Center, located at the Office of Education, participated in a field trip to a botanical garden, as a part of their program. Prior to the program, researchers developed a scientific creativity task for outdoor education program, along with science education specialists and teachers. The tasks were to observe plants, and to create something new and useful, or, in other words, scientifically creative, based on the plants' characteristics. The students could submit at most three ideas. Also, they assessed their own ideas, and selected an idea that they thought was the most creative. The results were analyzed by using the scientific creativity formula. The main findings from this study are as follows. First, it was found that the scientific creativity formula had an upward bias in assessing originality. Second, the students tended to assess the usefulness of their own ideas more generously. Third, the correlation between self-assessment results and scores from the scientific creativity formula for originality was r=.43. Fourth, in formula-based assessments, the correlation between originality scores and usefulness scores was relatively high, at r=.56. Fifth, the correlation between a student's scientific creativity score and the number of his or her ideas was very low, at r=.23. Sixth, when the ideas chosen as the most creative by students were compared with the ideas that had the highest scores in formula-based assessments, it was shown that 8 out of 19 students (42.1%) did not choose the idea that appeared to be the most creative when graded by the formula. This study is concluded by discussing the lessons from the scientific creativity task analysis for primary science education and gifted education.

Students' argumentation during science inquiry should be regarded important as it could help students to make meaningful connections between theories and experiments and to make scientific claims based on evidences. In this study, elementary science-gifted students' argumentation during small group inquiry was analyzed according to inquiry process. There were three stages of argumentation during students' inquiry. The first argumentation was to predict what would happen(Prediction stage). In this stage, the scientific problem was presented by concept cartoon as a way to start and to facilitate students' argumentation. The second argumentation was to design an experiment to solve the problem(Planning stage) and the third was to interpret the result of experiment(Interpretation stage). The discourse move, level of grounds and their relationship were analyzed to find the characteristics of argumentation during science inquiry. In terms of discourse move, 'Asking for opinion' was the most frequent whereas 'Claim' or 'Rebuttal' were rare. Students tended to listen to or ask others' opinion rather than provide their own claims or critics on others' opinion. 'Rebuttal' was shown a few times only during prediction and planning stage. There was no single 'Rebuttal' during interpretation stage. Students tended to easily accept or agree other student's interpretation of data instead of arguing their own ideas. In terms of level of grounds, students mostly provided their ideas without any attempt to justify their position. Especially during planning stage, students tended to suggest or decide ways of measuring or controlling variables without any grounds. They used evidences only a few times during prediction stage. In terms of relation between discourse move and level of grounds, students provided grounds most frequently when they dispute others' claims. The level of grounds were higher when they advocate or clarify their own or others' ideas than when they claim their ideas. The result of this study showed that the quality of elementary science-gifted students' argumentation during science inquiry was undesirable in many ways. Implications for scaffolding and facilitating argumentation during science inquiry were discussed.

This study explores factors that influence the development of creative ideas among apparel design students. This research is to understand how past experience (especially in art and design), influences the development of creative ideas in apparel design. The interaction between two related elements of student experience and work process is explored. A design process model based on Wallas's (1926) creative problem-solving process and Koberg and Bagnall's (1974) design process was used in the context of a beginning-level apparel design course comprised of Korean and Chinese students at a university in Seoul, South Korea. The results show that students with past experience in art and/or design performed differently than inexperienced students when faced with the same stimulation. Significant differences were also observed between experienced and inexperienced students in the development of creative ideas.
