This study analyzes the factors influencing academic achievement on mathematic and scientific subject and its change in Korean youth by using a sample from KYPS(Korea Youth Panel Survey) data. The results are as follows: First, academic achievement on mathematic and scientific subject of Korean youth shows quadratic curve that their interrelationship between intercept and slope of academic achievement are negative which is statistically significant. Second, analysis of Latent Growth Models shows that parents, teacher, peer group, self esteem, income of family, high school tracks are found to be a statistically significant factor on mathematic. And scientific subject is affected by parents, teacher, peer group, self esteem, income of family, high school tracks. Also, Interesting finding is that father's job is not significant to dependent variables. These findings show that academic achievement on mathematic and scientific subject of the Korean youth are the quadratic curve and influenced by parents, teacher, peer group, self esteem, income of family, high school tracks. To improve youth's mathematic and scientific, Korea educational fields and educators should have policy to care youth's relationship with parents, teachers and self esteem.

In the previous study on the effectiveness of SW education, the educational goals were mainly focused on developing computational thinking ability and researching changes in computational thinking ability. But the word "computational thinking" is difficult to the public. Also the definition of computational thinking is varies from scholar to scholar. Therefore, this study aims to inform the public of the excellence and effectiveness of SW education through the change of "writing ability" which is more familiar to us. To achieve this goal, 10 lectures of SW training materials were produced and conducted in elementary science gifted class. As a result, significant changes have been made in the fluency and quality of writing skills, proving that SW training improves students' writing skills. Through this, we confirmed the visible results through SW education, which can be called justification of SW education. Furthermore, it is expected that various educational attempts will be developed using SW in other subjects.

The purpose of this study was to investigate elementary gifted students' characteristics of observing and inferring in the inquiry activities. For this study, 40 students of the 4th and 5th grades participated in inquiry activities where the strata were developed well, Haenam Uhangri province. And we analyzed the outcomes of students' inquiry activities. The results are as follows. First, 119 units as observing results were obtained, but most of them showed that they were not focused on the portion of stratus, but that they were implicated in whole stratus as observing object. Second, 90 units were collected with reasoning results, but 4 units of them were wrong in constructing of inferring. Based on outcomes of students' inferring, elementary students preferred to apply deductive inferring method rather than use abductive inferring. Third, only 39 of 119 units acquired from observing were used for constructing inferring and 80 which were discovered from observing activities were discarded without applying of inquiry activities. Fourth, about 42% of students' inferring results were in accord with them of the geologists. But 58% views which didn't agree with geologists showed that they were applied to misconceptions among constructing inferring.

The purpose of this study was to investigate the relationship between instructional strategies applied to engineering courses and students' learning strategies. As a result, students perceived that the application principle was the most applied and then the problem-centered principle was applied to engineering courses. In addition, the students showed that rehearsal strategies are the most used in courses. The most important instructional principle in this study was the problem-centered principle, and the higher the degree of application of problem-centered principle in engineering course, the students were likely to use more deep learning strategies such as elaboration and organization strategy, critical thinking strategy, and metacognitive strategy.

The purpose of this study is to investigate the trends of character-related research in science education by analyzing science education research literatures in South Korea. To this end, literatures on character were extracted from the KCI-listed journals and theses from 1990 to December 2016, and analyzed according to the criteria such as terms relating to character, year of publication, research design and method, and research content. A total of 54 KCI-listed papers and 67 theses were extracted. As a result, 46%, 49%, and 5% of the researches include the terms like character, ethic, and moral in their titles. According to the year of publication, it was found that the number of research papers related to character increased rapidly by more than two times in 2012 as compared to the past years. According to research objects, researches about gifted students were the most common, and when considering the ratio of gifted students to general students, many studies related to character concentrated on gifted students. Starting 2009, research papers on qualitative and hybrid research design begin to advance as compared the number of papers in quantitative research design. With regards to research methods used, seven methods were classified; five of them ranged from 16% to 19% while interpretive research method was 12% and test tool validity study was the lowest at 2%. By extracting 30 representative keywords so as to analyze the contents of character-related researches, we found various implications to character in relation to nature and researches about SSI, etc. As time passed by, the contents of character-related research in science education became more diversified and the number of researches increased. New research contents appeared due to the needs of the times.

The study aimed to analyze middle school students construction of physics inquiry problems for open inquiry from the viewpoint of variable isolation and clarification, and investigate students' difficulties during the processes of variable isolation and clarification to get implications for teaching and learning strategies for small group open inquiry activities which have been included in the 2007 national curriculum. The participants were 4 students who had attended an outreach program for the science gifted run by a university institution located in Seoul area. They performed an open inquiry on egg drop for 13 lessons for 30 hours. Level descriptions for variable isolation and clarification have been developed and applied to analyze students' inquiry problems and variables included by the problems. Students iterated inquiry processed 5 times and the inquiry problem showed progress gradually. Dependent variables have been isolated ahead and the levels of variable isolation and clarification showed higher than the independent variables. Many kinds of independent variables isolated extensively and the independent variables and control variables have been mingled. One of the reasons why students had some difficulties in isolation of independent variables could be the absence of theoretical models. The realities of school lab could restrict the variable isolation and clarification as well as topic selections. Some sensory or extensive variables such as broken eggs and drop height seem to be salient to be focused on as core variables. Lack of background knowledges could be one of the reasons for students' difficulties in variable clarification, such as theoretical definitions and operational definitions. As a result of lacking background knowledges, students could not construct theoretical models even though they could isolate and clarify variables as scientific lexical definitions. Some perceptions of inquiry as trial and error or reckless establishment of causal relations between variables could be accounted as one reason.

The purpose of this study is to understand the decision-making behavior of a mathematics teacher in science academy of Korea by applying the framework of class analysis through the theory of goal-oriented decision-making. To this end, we selected as the participant a mathematics teacher in charge of the class of basic calculus of science high school for the gifted in the metropolitan area, and observed the teacher's lesson. Based on a questionnaire derived from previous studies, we analyzed goals, orientations and resources of the teacher. Research results show that there are certain teaching routines by analyzing the behavior patterns that appear repeatedly in the teacher's lesson. Also we understand that it can be used on goals, orientations and resources of the teacher to adequately explain his teaching routine. In the present study, in particular, it was found to have a similar but partially different routines to the teaching routines shown in the study of Schoenfeld. From these findings, We can derive the implications that the theory of goal-oriented decision making can be suitably used as analytical tool for understanding the behavior of the teacher who pursue a productive interaction in mathematics lesson in Korea.

The purposes of this study are to investigate the school science high achievers' achievements in enrichment physics, logical thinking level, and to analyze the relationship between logical thinking level and the achievement in enrichment physics of high achievers in science. The subjects were 357th and 8th graders who achieved highly in school science. To assess their achievements in enrichment physics, we developed a new test consisting of descriptive problems which were based on middle school curriculum. Those problems require one or two steps of thinking process, not simple knowledge of science. To assess logical thinking level, we used the instrument called GALT(Group Assessment of Logical Thinking) developed by Roadranka et al. The results showed that the school science high achievers' average achievement in enrichment physics was low, 56.3 out of 150, which indicated that they had not done much of enrichment learning beyond middle school science curriculum. Just only 54% of the school science high achievers are in formal logical thinking level. From the analysis of relationship between their logical thinking level and the achievement in enrichment physics, the value of the correlation coefficient was 0.174, which means that they are not almost correlated. Therefore, it is not desirable to judge science gifted children just from achievement in school science or enrichment physics, so both(logical thinking and the achievement in enrichment physics) tests should be taken for selecting gifted student.

This study aims to analyze the influence of parents' nurturing attitude on the children's self-esteem by comparing and analyzing the self-esteem of target children of gifted and talented education (GATE) and nongifted children with parents' nurturing attitude. The targets of this study are total 656 children in total. This study can be summarized as below. First, the self-esteem of target children of GATE turned out to be higher than that of nongifted children in overall, social, domestic and school life. Second, the nurturing attitude of parents felt by the target children of GATE is, from both father and mother, more affectionate, autonomous, achievement-oriented and rational. The parents of target children of GATE are more free in communication and fathers are aggressively in education; compared to parents of nongifted children, they put more importance on the course of achievement and help their children's achievement with actual way compared to the parents of nongifted children. Third, the relevance between self-esteem and parents' nurturing attitude is different in sub-areas. The self-esteem at home is the most relevant with parents' nurturing attitude, and the self-esteem at school is more affected by other factors than by the parents' nurturing attitude.

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.
