The Gifted need the constructivist loaming environments that reflect his or her cognitive and affective characteristics and needs to exert their potential fully. 'Structural Communication'was designed to encourage creative thinking in learners, allowing them to create an understanding of a topic, not simply memorize facts. It is considered in line with constructivist philosophy and cognitive paradigms. The major purpose of this study is to explore 'Web-Based Structural Communication'program to embody the collaborative loaming based on constructivism. It was applied on high school $2\times2$ matrix teaming for the gifted students. Recently developed computer technology, emerging network facilities, and internet enable us to extend the usefulness and efficiency of 'Structural Communication’Especially web provides not only the discussion environment that is free from space and time constraints and characteristics of leasers, but also the experiences of knowledge construction through the collaborative learning. Through the 'Web-based Structural Communication', the gifted will be able to argue, persuade and share their unique ideas and gradually elaborated ill-structured ideas. The gifted will escape from the tunnel vision of the early time and have multiple perspectives that are more objective and logical. As the result, the gifted are expected to acquire the effect of 'the Zone of Proximal Development'that Vygotsky advocated.

This study compared levels of mathematically talented students' statistical thinking with those of non-talented students in statistical modeling and sampling distribution understanding. t tests were conducted to test for statistically significant differences between mathematically gifted students and non-gifted students. In case of statistical modeling, for both of elementary and middle school graders, the t tests show that there is a statistically significant difference between mathematically gifted students and non-gifted students. Table of frequencies of each level, however, shows that levels of mathematically gifted students' thinking were not distributed at the high levels but were overlapped with those of non-gifted students. A similar tendency is also present in sampling distribution understanding. These results are thought-provoking results in statistics instruction for mathematically talented students.

Previous studies reported that gifted students' capacity on mathematics had high correlations with results of the performance assessment. However, there have been few studies that develop recommending tools through the assessment that can be used to identify mathematically gifted students or analyse their applications. Then it is difficult to use them to identify mathematically gifted students practically. Therefore, this study developed the tasks and evaluation tables for the tools. And one of them was applied for four students in Grade 1 of a middle school to simulate the assessment and characteristics assessment teachers showed were analysed. As the results, the extensive and specific information on the giftedness of the students was obtained through using the tool. The gifted capacity grasped from the order, speed, and attitudes of problem-solving was identified as observing the process of solving the task.

This study aims to show how scientifically gifted students think in terms of Thinking Style Inventory based on Sternberg's theory of mental self-government and to examine the relationships between their thinking styles, intelligence and creativity. Two hundred and sixty-six middle school students (169 boys, 97 girls) who enrolled in a gifted education program participated in this study. Results indicated that scientifically gifted students prefer legislative, liberal, judical thinking styles, in comparison to general students, known to be related to creative and critical thinking rather than executive and conventional styles. There was no significant correlation between any of thinking style sub measures and Raven' Matrices and Scientific Aptitude Test, but some correlations were found among the sub measures of thinking style and TTCT. Whereas liberal students gained high originality scores, conventional students gained low fluency scores. Also, judical thinking style showed significant correlations with originality and flexibility TTCT sub scores. In sum, this study showed the characteristics of thinking styles of scientifically gifted students and provided implications for gifted education based on the findings presented.

The observation and recommendation system was recently introduced for selecting gifted-students in science, and it has required to arrange the reliable and valid selection criteria that could identify the high potential competency of them. In this study, we explored the competencies that could help to discriminate gifted-students' inner properties, and also developed the dictionary based on them. The competencies were extracted from the proven previous competency dictionaries/models and examined by the structured survey and the focus group interview in order to ascertain the competencies of the science-gifted students. The results revealed that there were two competency clusters such as cognitive and affective domains. The cognitive cluster consisted of 6 competencies as follows: goal suggestion, planning, information collection and analysis, problem solving, higher-order thinking, and expertise and self-development competency. The affective cluster consisted of 3 competencies: confidence, achievement orientation, and curiosity competency. The dictionary categorized by the names, definitions, key elements, and behavioral indicators and their levels of the derived competencies was developed. Findings were expected to provide the implications on the selection criteria of the potential science-gifted students through the observation and recommendation system.

A good understanding of how gifted science students understand physics is important to developing and delivering effective curriculum for gifted science students. This dissertation reports on a systematic investigation of gifted science students' reasoning model in learning physics. An analysis of videotaped class work, written work and interviews indicate that I will discuss the framework to characterize student reasoning. There are three main groups of students. The first group of gifted science students holds several different understandings of a single concept and apply them inconsistently to the tasks related to that concept. Most of these students hold the Aristotelian Model about Newton's second law. In this case, I define this reasoning model as the manifold model. The second group of gifted science students hold a unitary understanding of a single concept and apply it consistently to several tasks. Most of these students hold a Newtonian Model about Newton's second law. In this case, I define this reasoning model as the coherence model. Finally, some gifted science students have a manifold model with several different perceptions of a single concept and apply them inconsistently to tasks related to the concept. Most of these students hold the Aristotelian Model about Newton's second law. In this case, I define this reasoning model as the coherence model.

The purpose of this study is to survey its characteristics through analyzing brain-wave activity in the scientifically-gifted and general children in the problem-solving process. The subjects of this study were 6 elementary school students, who are attending the institute of education for the gifted belonging to the regional office of education and 6 general children in the same region. The analysis was performed targeting total 12 people. As the task for measuring brain wave is Hanio tower, it is the effective task of researching into the problem-solving process. As the equipment of measuring brain wave is EEG System, it used equipment that was developed in Australia. The analysis of data was minimized noise. As a result of research, the gifted children are excellent in stable level compared to general people in a stable situation with opening the eyes, thereby being able to be known to be high in preparatory level for learning. This can be seen to be indicated as a result that the effect of learning is excellent due to being high in preparatory level for solving problem. Also, even in the process of performing task, the brain-activity level in the gifted children is high, thereby having been able to know that ${\alpha}-wave$ is formed that is significantly high in the regions of frontal lobe and occipital lobe. Accordingly, given developing task that is high in brain activity level of the gifted children, the higher educational effect will be able to be expected.

The purpose of this research project is to explain why high-achieving high school students in our country do or do not choose a science major and to explore gender differences. First-year students attending science high schools and international high school participated, responding to open-ended questions on science activities, self-concept of strengths for science learning, and rationales for choosing or not choosing a science major. For high- achieving students, it is shown that intrinsic interest has the greatest correlation with choosing a science major, with the next important influence being self-efficacy. On the other hand, in not choosing a science major, the lack of self-efficacy has a greater correlation than the lack of intrinsic interest. Self-concept in science-learning and science activities occurring outside of school classes are also compared and analyzed, and implications are discussed from educational and policy viewpoints.

This study investigated the analysis of examples that gifted students' realizing the learning objectives through teaching method of the teacher's questions and advice. 6 gifted students were selected to be examined with 'magic square' in class. The teacher emphasized the learning objectives without directly proposing. Whereas, the teacher proposed the learning objectives by questioning and giving advice to students. After the class, the 6 gifted students were surveyed to answer about realizing the learning objectives of mathematics (about contents, process, and attitude in mathematics learning objectives). Mathematical gifted students thought about the process that consists of deductive thinking, analogic thinking, extensive thinking, creative thinking, and critical thinking. But, they underestimated the deductive thinking. So the teacher should develop the questions and advice to teach the mathematical gifted students according to the level of them. The high level of mathematical gifted students were able to realize the value and the importance of the mathematical attitude, while the low level of mathematical gifted students were able to realize them little. For this reason, the teacher should apprehend the level of the students, and propose materials and contents of the learning. The teacher should also make the gifted students realize value, will, and personality of mathematics by questions and advice. Lastly, like it is needed in general classes, there should be a constant researches and improvements about questions of the teacher that are appropriate to each student's learning abilities and cognition ability.

The aims of this study are to investigate how Kepler found a scientific problem for the retinal image theory and to investigate how the science high-school students respond when the same situation is applied to them. And their results was compared with general high-school students' results. Kepler found the scientific problem in the eye vision through the critical analysis of contemporary theories of vision, based on his relevant knowledge of optics. When we applied the same situation to the Korean science high school and general high-school students, only a few of science high-school students found the scientific problem as same as Kepler's finding. From the results, it is suggested that in development of creativity teaching material, the situations like Kepler's problem finding need to be included in the programs.
