The subjects of this study were 180 elementary school students from multi-cultural families and general families. The purpose of this study was to examine the differences in self-concept and career development within two groups and the correlations between self-concept and career development. Also, it was to investigate the self-concept's effects on career development. The results were as follows: First, the children from general families showed higher academic-occupational exploration than those in multi-cultural families. Second, the self-concept had significant correlations with career development in both groups. And there were stronger correlations in children from multi-cultural families. Third, the regression analyses of two groups showed that academic self-concept had significant effects on career development in both groups, but there were higher effects in children from multi-cultural families.

The purpose of this study was to identify whether the elementary school students force conceptions may influence on designing tools experiments. Four questions with multiple choices and reasons for those choices were asked to identify scientific/alternative force conception. Also four tasks for tools experiments matched to each force conceptions were developed into open questions in hypothesizing. controlling variables and methods of experiments. Forty elementary students were selected from 4 classes in sixth grade of a school in Daegu city. The major findings of this study were that the types of force conceptions can be classified into scientific and alternative conceptions. The patterns of designing experiments could be identified with types of hypothesis, controlling variables and methods of experiments in each four tools experiments. But students those who had scientific force conception did not better in hypothesis, methods of controlling variables and results for simple experiment than those who had alternative force conceptions. These results imply that students' force conception did not influence on designing tools experiments. The assumption that scientific conception could improve designing experiments was not guaranteed by this results.

The purpose of this study is to investigate gifted students in elementary mathematics how they understand of situations involving multiplication and concepts of multiplication. For this purpose, first, this study analyzed the teacher's guidebooks about introducing the concept of multiplication in elementary school. Second, we analyzed multiplication problems that gifted students posed. Third, we interviewed gifted students to research how they understand the concepts of multiplication. The result of this study can be summarized as follows: First, the concept of multiplication was introduced by repeated addition and times idea in elementary school. Since the 2007 revised curriculum, it was introduced based on times idea. Second, gifted students mainly posed situations of repeated addition. Also many gifted students understand the multiplication as only repeated addition and have poor understanding about times idea and pairs set.

The purpose of this study is to analyze elementary students' conceptual metaphor forms of light through their image schema of light. The participants were 162 $6^{th}$ grade students from G city, Gyeongsangnam-do. For this study, the analysis framework was developed as image schema analysis and systemic functional grammar analysis. Then, students' metaphorical expressions of light concepts were analyzed by the framework(image schema analysis and systemic functional grammar analysis). The findings are as follows. First, in the understanding of source of light, students had two structures of light. (a)Light comes out from a light source and goes straight in space. (b)Light is dispersed around a light source. Second, in the understanding of the process to see a material, students had five structures including scientific concept as light came out from a light source approaches the material and reflects off the material, then the light goes into the person's eyes. Third, in the understanding of reflection of light, students had four structures including scientific concept as light came out from a light source approaches the mirror and is reflected from the mirror.

In this study, we analyzed pre-service teachers' levels of pedagogical reasoning while watching video clips of elementary school students' discussions of their conceptions of solution and dissolution. 81 pre-service teachers participated in the study. It was found that many pre-service teachers had scientific conceptions, and pre-service teachers who had non-scientific conceptions showed misconceptions similar to those of elementary school students. In both conceptions, pre-service teachers partially or comprehensively interpreted the students' misconceptions with reference to the evidence. However, the rates of pre-service teachers who misinterpreted or simply restated the students' utterances were quite high. Many pre-service teachers suggested only one factor related to levels of reasoning about causes of misconceptions, and most suggested factors were related to the student factor. The level of reasoning about instructional decisions differed according to dissolution and solution conceptions. Actions linked to students' thinking were more closely related to students' specific thinking than to their generic thinking, and among these, student-centered action was seen. From the above results, we sought ways of improving pre-service teachers' pedagogical reasoning.

This study was to investigate the preconception and phases of children's conceptual change about season through an instruction on the concept. Participants in the study were seventy-eight fifth graders in two classrooms of an elementary school located in Incheon city. Children's preconception was examined using a questionnaire, consisted of a drawing and literal explanation. The questionnaire also was used at the midterm-test, post-test, and one-week delayed-test. The results shows several findings as follows: some children (a) change their synthetic conceptions to form another synthetic conceptions through the instruction; (b) exhibit that their conceptions are unstable; and (c) are mainly influenced by distance and heating effect on the seasonal spatial distribution between the Earth and the Sun, and by the Earth's rotation on the seasonal change of constellations in acquiring the scientific concepts.

The purpose of this study is to examine the misconception profiles of the scientifically-gifted and non-gifted children in terms of basic physics concepts and to compare them in terms of the types of differences in misconception as well as in their understanding of the concepts themselves. The subjects of this study were 75 scientifically-gifted children attending the Educational Center of Gifted Children in DNUE and 148 non-gifted children in elementary schools in Daegu city. For the purposes of this study, the basic concepts of physics (heat, electromagnetism, force, and light) which should be learned in an elementary school were selected with a review of related previous research and with an analysis of the 7th science curriculum. Next, a questionnaire was made which was made up of 20 multiple choice statement based items. Analysis of the results of the statement sections in the test, it was hoped, would reveal the difference between the scientifically-gifted and the non-gifted children's understanding, while the responses in the multiple choice items would suggest the differences between the two groups in terms of the misconceptions regarding physics concepts. The results of this study are as follows: First, although both the gifted and non-gifted children showed a low level of understanding of the concepts of heat, electromagnetism, force, and light, the gifted children' level of understanding of those physics concepts was proved to be significantly higher than the non-gifted, so it seems that the scientifically-gifted children have fundamentally understood the concepts in physics and have a higher level of understanding of them. Additionally, both the scientifically-gifted and non-gifted children' level of understanding of all the concepts was lower in the order of electromagnetism, heat, force, and light. This shows that both the scientifically-gifted and the non-gifted children have no difference in the level of understanding of any specific physics concept, but have similar levels of difficulty in every concept. Second, both the scientifically-gifted and non-gifted children showed similar types of misconceptions. However, the scientifically-gifted children had fewer misconceptions than the non-gifted. We suggest that scientifically-gifted children's misconceptions were not fixed yet, so there remained a possibility of them being corrected easily with appropriate instruction.
