The purpose of this study was threefold: (1) to select the components of spatial ability that could be associated with the implementation of a polycube task, embody the selected components of spatial ability as learning elements and develop the prototype of polycube teaching-learning materials applicable to gifted education, (2) to make a close analysis of the development process of the teaching-learning materials to ensure the applicability of the prototype, (3) to give some suggestions on the development of teaching-learning materials geared toward mathematically gifted classes. The findings of the study were as follows: As for the first purpose of the study, relevant literature was reviewed to make an accurate definition of spatial ability, on which there wasn't yet any clear-cut explanation, and to find out what made up spatial ability. After 13 components of spatial ability that were linked to a polycube task were selected, the prototype of teaching-learning materials for gifted education in mathematics was developed by including nine components in consideration of children's grade and level. Concerning the second purpose of the study, materials for teachers and students were separately developed based on the prototype, and the materials were modified and finalized in light of when selected students exerted their spatial ability well or didn't in case of utilizing the developed materials in class. And then the materials were finalized after being finetuned two times by regulating the learning type, sequence and degree of learning difficulty. Regarding the third purpose of the study, the polycube task performed in this study might not be generalizable, but there are seven suggestions on the development process of teaching-learning materials.

In this study, we investigated the effects of coteaching science instruction in elementary science-gifted education upon students' concept application ability and their perception of the instruction. Fifth graders (N=37) from two science-gifted classes in two elementary schools were selected and assigned to control (n=19) and coteaching instruction (CI, n=18) groups. Two teachers prepared, executed, and evaluated together the instructions for science-gifted elementary students during twelve classes in the CI group, and so did one teacher with the same programs in the control group. After the instructions, the students in the two groups were administered with a test of concept application ability. All students in the CI group were also administered with a questionnaire on the perception of the instruction and were deeply interviewed. The results revealed that the scores of those in the CI group were significantly higher than those in the control group in the test on concept application ability. Many students in the CI group perceived the coteaching science instruction positively upon verbal interaction, class management, and cognitive/affective aspects. However, some of them also pointed a few disadvantages of the instruction. Educational implications of these findings are discussed.

The purpose of this study is to analyze characteristics of problem solving in mathematics for gifted students through case study on solving the mathematical problem for gifted students, and to investigate what are relationships with the cognitive and affective characteristics. To this end, this study was to analyze the characteristics on the problem solving in mathematics by using qualitative research method after it selected two students who had specific education for brilliant students. As a result, this study has shown that it had high preference for question with clear answer, high preference for individual inquiry learning, high adhesion to answer for question, and high adhesion for assignment on characteristics of process of problem solving, but there was much difference in spirit of competition. As to the characteristics of thoughts in problem solving, this study has shown that it had high grasp capacity, intuitive insight, and capacity for visualization, but there were differences in capacity for generalization and adaptability. However, both two students had low values in deductive thought. In addition, as to the home environment and cognitive and affective characteristics, they were not related to the characteristics on problem solving directly, but it has shown that it affected each other indirectly. As to the conclusion of this study, this researcher thinks that it will be valuable documentation in order to improve curriculum, development of textbooks, and teaching method for special education for the gifted students and education for secondary mathematics.

The major purpose of this article is to examine what kind of gap exists between mathematically gifted students' probability knowledge and the reality actually applying that knowledge and then analyze the cause of the gap. To attain the goal, 23 elementary mathematically gifted students at the highest level from G region were provided with problem situations internalizing a probability and expectation, and the problems are in series in which conditions change one by one. The study task is in a gaming situation where there can be the most reasonable answer mathematically, but the choice may differ by how much they consider a certain condition. To collect data, the students' individual worksheets are collected, and all the class procedures are recorded with a camcorder, and the researcher writes a class observation report. The biggest reason why the students do not make a decision solely based on their own mathematical knowledge is because of 'impracticality', one of the properties of probability, that in reality, all things are not realized according to the mathematical calculation and are impossible to be anticipated and also their own psychological disposition to 'avoid loss' about their entry fee paid. In order to provide desirable probability education, we should not be limited to having learners master probability knowledge included in the textbook by solving the problems based on algorithmic knowledge but provide them with plenty of experience to apply probabilistic inference with which they should make their own choice in diverse situations having context.

The purpose of this study was to explore the problem solving strategy for Goldberg machine tasks of the gifted students in elementary science depending on the cognitive style(tendency to field-dependent and field independent). It was aimed to provide suggestions for the features and differences of the problem solving strategies of the gifted students in elementary science according to their cognitive styles. A total of 16 students, from the gifted class of P elementary school in Hwaseong were sampled for the research, cognitive styles Test was conducted to divide the students in teams, and the teams were classified according to cognitive style tendencies to five groups of field-dependent group, weak field-dependent group, mixed group, weak field-independent group and field-independent group. The Goldberg device task given was to make a Goldberg device within the angle framework of (Figure) 1, for a bead to start from the starting point and to reach the final point the last. The results are as follows: First, regarding the plan for producing the device, the stronger the field-independent tendency, they established more specific strategy-reflected plan; the stronger the field-dependent tendency, they established less specific strategy-reflected plan. Second, all cognitive style groups took a limited period of time into consideration, to fabricate the devices for the ball to arrive the last using a fine adjustment rather than many devices. Third, the field-independent group used a lot of logical reasoning; the field-dependent group used a lot of intuitive thinking. Fourth, the field independent group properly utilized strategies such as cooperation and role allocation; the field-dependent group tried to solve the task personally rather than cooperatively with poor role allocation. Fifth, the intermediate mixed group solved the problem better than the inclined groups such as field-dependent or field-independent groups.

This study try to analyze the effect that personal and social factors affects the interactions among science gifted students. For this, I analyze the interacting role of science gifted students in social co-construction and scientific model constructing class for phase change and rising-sinking time of moon and categorize according to type. I analyze aspects of interaction and association of each elements in the students after I understand character type self conception friendship a parents-children relationship relation with teachers derived from advanced research through questionnaire and depth interview. After analyzing, I find the following-close friendship form or not and usual school class participation appear important factors that have strong connection with the aspect of the interactions. Also, character type, self conception and relation of parents affect the interactions relatively lower. Through this study, We identify two things. Firstly, We must consider individual's inside factors for making animatedly the interaction among the students. Secondly, We get considering factors that devise the strategies for making the interaction animatedly.

The Korean Ministry of Education has emphasized the convergent ability for human resource cultivating the development of science and technology in the future. Based on this, Korean STEAM education aims to enhance students' interest and their understanding of science and technology as well as to develop students' convergence thinking and problem-solving skills. Through the camp for gifted students, students are generally introduced to produce self-directed outputs in order to solve the problem in everyday life. In this study, the author aims to find out whether the gifted high school students' creative leader competency and STEAM literacy changed after they experienced STEAM-based camp. 517 gifted students from 52 high schools in the Metropolitan city region join the camp, which is focused on generating student-centered outputs for problem-solving in daily life context. Before and after the camp, the creative leader competency and the STEAM literacy of participants were tested and compared. From the result, we found that the gifted high school students' creative leader competency and STEAM literacy improved after participating in the STEAM camp. In particular, all the sub-factors except for the social value pursuit domains in the social characteristic area of creative leader competency and the areas of creativity, respect, and communication in STEAM literacy increased. Educational implications will be discussed.

The purpose of this study is to develop the argumentation program to build scientific concepts on natural selection for science-gifted elementary students and to know how to implement this program. For this study, nine key concepts about natural selection such as the overproduction of offspring, limited resources, population stability, competition, variation, heredity of variation, differential survival, change of the population and speciation were selected through the literature study. The programs were developed by learning cycle instructional model. Argument writings and discourses have been collected, analyzed and compared before and after the program. Two questionnaires to compare pre and post concept change consist of multiple choice questionnaire and open-ended response question were developed and applied to 19 science-gifted elementary students. Sufficiency of the explanation and conceptual quality of the explanation were used to assess the quality of their arguments before and after the program. Discourse and visual models collected from the highest and lowest group about score improvement were compared. The scores of the gifted statistically improved significantly in multiple choice questionnaire. Students' alternative conceptions about natural selection at the beginning of the program decreased and changed scientifically after the program. Visual models drawn by the students supported the results as well. This study asserts that elementary science-gifted students are able to explain evolutionary perspectives about organism change and use the key concepts of natural selection. The study means that evolutionary perspective is possible to be reflected in elementary science curriculum for the gifted.

Nim games were divided into three stages : one file, two files and three files game, and inquiry activities were conducted for middle school mathematically gifted students. In the first stage, students easily found a winning strategy through deductive reasoning. In the second stage, students found a winning strategy with deductive reasoning or inductive reasoning, but found an error in inductive reasoning. In the third stage, no students found a winning strategy with deductive reasoning and errors were found in the induction reasoning process. It is found that the tendency to unconditionally generalize the pattern that is formed in the finite number of cases is the cause of the error. As a result of visually presenting the binary boxes to students, students were able to easily identify the pattern of victory and defeat, recognize the winning strategy through game activities, and some students could reach a stage of justifying the winning strategy.
