A Discourse Analysis tool has been developed and has been applied in the cooperative group inquiry activities in order to derive the characteristics of elementary gifted students in science. We recorded and videotaped the whole group problem-solving processes where 4 elementary students worked together to solve given problems as a group for one year in a gifted education center attached to a university in Seoul. We analyzed recorded discourses using systemic functional linguistics with a focus on the structure of information and topic. The discourse analysis tool was developed with the cooperation of science education and gifted education experts. In discourse analysis, we focused on meaning development processes rather than grammatical analysis. Through application of newly developed discourse analysis tool, we confirmed that the tool is useful in understanding the characteristics of science-gifted elementary students. We also founded that the interaction between students has significant effects on problem-solving processes by comparing two students who showed contradictory features in the share of dialogue. In addition, the result suggested that we need to provide students with proper training for ways to communicate with others for effective science-gifted instruction.

This study analyzed the characteristics of National Science Curricula in the UK, Australia, New Zealand, Canada, Singapore, and Korea with respect to core competencies. In the case of overseas countries, literature review on their curricula was conducted, and four common features were extracted: 'association of cross-curricular competencies with science-specific competencies', 'a combination of science contents and scientific practices', 'an emphasis on communication skills', and 'representation of an achievement level of competency'. In addition, the common core competencies of science education were 'critical thinking', 'creative thinking', 'problem solving', 'inquiry skills', 'communication skills', 'cultural literacy', 'ability to integrate discipline', 'application skills', and 'personal/social competency'. In relation to these features, this study also investigated Korean science teachers' perceptions of core competencies in science education. A survey was conducted on 135 teachers in elementary, middle, and high school in Korea. Teachers were not well aware of what core competencies are, and after introduction, they thought that they wanted to and needed to teach core competencies to their students. Teachers claimed that critical core competencies in science education are 'creative thinking', 'problem solving', and 'inquiry skills'. Teachers thought that core competencies-based science class would help develop students' scientific literacy and communication skills. However, they have difficulties in conducting core competencies-based science class because they are not familiar with how to conduct the class and they expect that it will take a long time to prepare such a class.

Recently KISTEP(Korea Institute of Science and Technology Evaluation and Planning) held an open forum for examining 'the Manuscript of National Science and Technology Standard Taxonomic System'. I submitted my opinion letter to the forum because I thought that the matter of setting the standard taxonomic system for Science and Technology is so closely related to the research concern of STS that it needs checking from the viewpoint of STS. This paper primarily focuses on making a criticism of and constructing an alternative to the mamuscript, but it goes so far as to ground the matter upon the STS viewpoint. I propose that we interpret an open forum related to science and technology as an example case of the community of inquiry. Further I try, standing in the context of learning to form a model of doing STS interdisciplinary research. In the context of decision I point out the problem with the 'scale' principle involved in categrizing criteria of the taxonomic system and argue that the problem leads to omitting STS from National Science and Technology Standard Taxonomic System although STS takes up science and technology themselves as its research concern proper. In the context or teaming I seek to set up a typical case study or STS. One of the typical STS research tasks is trying to construct a positive alternative to as well as make a criticism of a given suggestion, for clearer alternatives will, in him, provoke sharper criticisms or safer acceptances. I hope that the model in this paper will exemplify such an alternating procedure of criticism and acceptance.

The purposes of this study were to develop teaching strategy enhancing the activity to explore variables and to examine the instructional influences on students' creative thinking skills and critical thinking skills. In this study, a model using listing-excluding-controlling variables (DPAS model) was designed and applied to the existing 'Teaching model for the enhancement of the creative problem solving skills'. And it was implemented to preservice science teachers for the one semester. Results indicated that the experimental group presented statistically meaningful improvement in creative thinking skills, especially in recognizing problems, making hypothesis, controlling of variables and interpreting & transforming of data (p<.05). In addition, the strategy contributed to improve critical thinking skills, especially in making hypothesis and making conclusion & generalization (p<.05).

This study was performed to survey the achievements in problem solving by the inquiring experiment, which was done by the superior group in the traditional cocepts-centered written tests. The purpose of this study was to identify characteristics of inquiring experimental assessment by analyzing differences between concepts-centered written and inquiring experimental tests. The subjects of this study was 211 applicants. They are the superior group of the 9th grade students, and score in the top 1% of total achievements percentage in school. They also have passed the primary entrance examination. The inquiring experimental test was developed according to the curriculum in school, and is composed of 5 subcategories: problem-perception and formulating hypothesis, designing an experiment, carring out an experiment, recording data and drawing conculsion, and generalizing conculsions and communicaton. The checklists of each subcategory were made and testing methods were divided into observation and report. The major results of this study are as follows: 1. The achievements in each subcategory of inquiring experimental performance were very low in the superior group who took the concepts-centered written tests. 2. The results of factor and correlation analyses in this study confirmed the abilities measured by inquiring experimental assessment differed from abilities measured by existing tests. These results indicated that even students who achieved high in scientific knowledge, these abilities were not automatically transformed inquiry process which many other abilities were integrated into. Therefore, problem solving ability requires integrated abilities which are fostered by inquiring experimental tasks. This suggests that new instrument for assessment must be developed to measure integrating ability especially where scientifically gifted students are selected, or where entrance examinations to the science schools are administered.

As an exploratory inquiry prior to developing a measure to assess Korean families with adolescents' family resilience, this study examined the construct validity of the family resilience measures that were developed in the U. S. Iowa Youth and Families Project(Conger & Elder, 1994): emotional support between spouses, problem solving style between spouses, and parenting behavior. The participants were 277 pairs of middle aged, middle class husbands and wives (554 individuals) who were the parents of first graders in middle schools in the metropolitan areas around Seoul. The results of exploratory and confirmatory factor analysis supported the construct validity, indicating that emotional support, problem solving style, and parenting behavior may be used as measures to assess Korean family resilience. However, further tests of convergent validity using various assessment methods and analytical procedures are needed to ensure the construct validity of family resilience measures.

This study was investigated to examine the effects of writing activities based on Polya's Problem Solving Stages on Learning Accomplishment and Attitudes. A total of 54 students were selected from two Grade 6 classes of P Elementary School in G City to form an experimental group(n=27) and a control group (n=27). The experimental group was applied to a class which was creating writing activities according to Polya's Problem Solving Stages to problem solving and inquiry activities. The control group was taught by the traditional method to the same activities. The five questions for each area were selected as a descriptive assessment of the second semester of Grade 5 in the area of the Academic Achievement pre-test, developed by the G Education and Science Research. The post-test was selected by a descriptive assessment of the content of the first semester in Grade 6. The same questions were posed for both the pre-test and the post-test of the Mathematical Attitudes assessment. We examined the pre-test at the beginning of the school term, then the students were re-examined after one semester, using the same questions as the pre-test. This research showed that there was a meaningful difference in Learning Accomplishment as a result of T-test in the 5% level of significance. Secondly, there was a meaningful difference in the Mathematical Attitudes as a result of T-tests. It shows that writing activities based on Polya's Problem Solving Stages have an influence on improving Learning Accomplishment and Attitudes.

The purpose of this study is to analyze the 2015 revised Science Curriculum and Environment Curriculum, and to provide implications for the correlation and complementarity between the two standards. For the analysis of the curriculum, the contents system of the two standards was reorganized based on the four categories of knowledge, attitude, inquiry, participation and practice, which are common literacy elements of science and environment, based on previous studies. Content Analysis was performed on content elements and detailed performance expectation. As a result of this study, there was a difference in terms of the core competencies and goals. The Environment Curriculum emphasized sustainable development and social participation while the Science Curriculum emphasized scientific inquiry and literacy. The contents system analysis results according to the four literacy factors are as follows. First, in terms of attitude, both standards deal with research ethics in common. However Environment Curriculum values learners' values and views on the environment more than Science Curriculum which emphasizes the science attitude as science investigators. Second, there was a serious problem in the knowledge linkage between two standards. In same grade groups, the level of content knowledge dealt in two standards was not consistent. Third, in the inquiry aspect, the Environment Curriculum deals with interdisciplinary topics in the purposefully designed inquiry unit, whereas the Science Curriculum presents various research activities based on related science concepts in every unit. Fourth, in the participation and practice aspect, the Environment Curriculum focused on participation and practice while the Science Curriculum focused on sustainable science and technology development and improvement, scientific interest and decision-making ability. This study provide implications for education for sustainable development(ESD) by providing the complementary potentials between Science Curriculum and Environment Curriculum.
