We investigated perceptions and image analysis on scientists studying small organisms reflected in elementary student's drawing using a modified version of the Drawing-A-Scientist-Test. The participants were 530 of fifth and sixth graders consisted of 449 ordinary students and 81 science gifted students. The data were collected from associated words, images and explanatory notes depicted by students engaged in questionnaires. The results indicated that a larger number of students reminded small sized animals and/or plants as words associated with small organisms. In addition, some students depicted anthropomorphic or abstract microorganisms. In this study, more stereotypes of scientists' appearance were exhibited at sixth graders and city region group. Most of the students depicted indicators such as lab coat, glasses, scientific instruments for observing, indoor, male and young, whereas only a few students depicted collaborative work. There was statistically significant difference between girls and boys, because boys perceived male scientists only, while half of girls depicted female. More frequent research instruments and scientific captions were used when science gifted students depicted scientists studying small organisms. These results could be contributed to education on microorganisms in elementary science.

Our study is composed of Arduino robot assembly, board connecting and collaborative programming learning, and it is to evaluate their effect on improving secondary mathematics-science gifted students' convergence capability. Research results show that interpersonal skills, information-scientific creativity and integrative thinking disposition are improved. Further, by analyzing the relationship between the sub-elements of each thinking element, persistence and imagination for solving problems, interest of scientific information, openness, sense of adventure, a logical attitude, communication, productive skepticism and so on are extracted as important factors in convergence learning. Thus, as the result of our study, we know that gifted students conducted various thinking activities in their learning process to solve the problem, and it can be seen that convergence competencies are also improved significantly.

The purpose of this study was to investigate teachers' perceptions of gender differences in students' mathematics and science learning ability. The sample included 289 elementary and secondary school gifted teachers. The teachers filled out the survey, asking their perceptions of gender differences in mathematics and science learning ability, as well as of the reasons of the differences. The results were as follows: 1) 65% of the teachers responded that gender differences existed in students' mathematics and science learning ability, 2) 63% of the teachers perceived that the differences began around higher elementary or middle school ages, 3) 57% of the teachers thought that gender differences existed in the high-achieving student group. Teachers perceived the reasons of differences were 1) differences in inborn ability, 2) the different expectation, and 3) the different ways of parental cares. Since teachers' perceptions of students' ability would impact teachers' attitudes on students, implications and suggestions were included in this article to provide teachers insights that promote students' better learning.

This study investigated the relationship between science high school teachers' beliefs of gifted education and classroom practices. The data of this case study were collected from three science teachers who worked in a science high school through qualitative research methods such as interviews and classroom observations. The other various data related to science high school management and the teachers' teaching were collected and analyzed using the constant comparative method. The results of the study are as follows: the teacher of long period in-service experience in science high school had teacher-centered belief, and his classroom practices were matched with his beliefs. The teacher of short period in-service experience in science high school had student-centered belief, and her classroom practices were matched with her beliefs, also. The teacher of medium period in-service experience in science high school had student-centered belief, but her teacher-centered classroom practices were mismatched with her beliefs. From the results, it could conclude that school culture affects on teachers' classroom practices stronger than beliefs. The longer career period of science high school changed easier teachers' beliefs into knowledge education for university entrance examination removed from gifted education. To solve these problems, we suggest the needs of teacher education programs for science high school teachers.

The purpose of this study is to investigate elementary school science gifted students' perceptions about Earth systems and environmental problems. A total of 28 students in the attached center for science gifted education to the university participated in this study. Through the survey, participating students were asked to respond to their self-reported knowledge level, the perceived danger levels, certainty, and tangibility of the selected 13 Earth environmental problems. The DAET (Draw-An-Earth Test)-Checklist were developed and used to analyze the images of the Earth drawn by students. Additional interviews were conducted to clarify the meanings and components of students' image. Results indicated that a total of 80 components regarding Earth systems, 11 components of Earth systems interaction, and 4 components related to Earth systems literacy were identified through the DAET-Checklist and additional interviews. Regarding the students' self-reported knowledge level, they reported that they were most knowledgeable about air pollution, global warming, and water pollution. and they also recognized global warming, air pollution, and water pollution as the most dangerous problem. Results indicated that participants were certain that acid rain, air pollution, and water pollution were problematic, and that acid rain, air pollution, and forest desertification were tangible issues. It is anticipated that this study contributes to understanding the elementary school science gifted students' perceptions toward the selected Earth systems and environmental problems.

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.

In this study, we developed analogical experimental activities to foster scientific creativity in inquiry learning and applied them to 7th grade science-gifted students. The influences of inquiry learning-based analogical experiments were investigated with respect to the experimental design processes. We classified the patterns of experimental design processes by creative thinking processes and analyzed performance levels by the elements of experimental design processes. The students' experimental design processes were categorized into three kinds of patterns such as reinitiated motion, backward-divergent motion and stationary motion. Those belonging to the reinitiated motion performed precise experimental design from new perspectives by identifying the mapping in depth and considering the elements of experimental design processes. In the case of the backward-divergent motion, they shifted their positions to new directions, but the concreteness of experimental design was insufficient due to the lack of mapping or considering the elements. In the type of stationary motion, maintaining their previous positions, they showed less performance of experimental design without considering the elements sufficiently. Educational implication of these findings are discussed.

We investigated brain activity during the performance of the intelligence task by a science high school student group (n=8) and a foreign language high school student group (n=5). Both groups scored in the top 1% on intelligence tests (science high school group: RAPM mean score=34.0, WAIS mean IQ=139.6; foreign language high school group: RAPM mean score=33.8, WAIS mean IQ=147.2). Analysis of brain activity during the performance of the intelligence task showed that both groups had brain activity in certain areas, including the left and right prefrontal cortex, parietal cortex, and anterior cingulate. The science high school group showed the highest activity in the right parietal cortex, which is related to visuo-spatial working memory, whereas the foreign language high school group showed the highest activity in the left prefrontal cortex, which is related to verbal working memory. The foreign language high school group showed higher brain activity than the science high school group in the left precentral gyrus which is related to the motion of the tongue and lips. These results show that the science high school group utilized the visuo-spatial area, whereas the foreign language high school group utilized the verbal area during the performance of the intelligence task. This suggests that the major thinking process differs depending on the gifted students' primary field of study, although they are doing the same task.

In this study, we investigated how scientists and teachers engaged in mentoring program are conducting research ethics education and how they are creating an ethical educational environment. A questionnaire survey was given to 32 scientists and 44 teachers conducting mentoring programs for gifted high school students. In the content of research ethics education, most of the respondents opined that they should teach against falsification, plagiarism, and fabrication. Teachers were most likely to teach ethical decision-making in each step of the research process. Most of the scientists said that they should teach how to write research note. For the difficulties, the teachers pointed out the challenging system that focuses only on college entrance exams while the scientists answered that it was difficult to recognize research ethics as the problem of the students themselves. For the teachers, the most affective factor in creating an ethical research environment is the amount of time to teach research ethics while for the scientists, it is the ethics of the mentors. For creating an ethical research environment, the teachers responded with making an atmosphere wherein failure is tolerated, and the scientists responded with increasing the degrees of freedom in results. For the difficulties of creating an ethical research environment, the teachers were constrained by research time while the scientists were pressured about the results. These results provide implications for ways to teach research ethics and for ways to create an ethical research environment in the mentoring program for science-gifted students.

The purpose of this study is to categorize preconceived notions by elementary science gifted students about the reason why only one side of the moon is visible and develop an instructional module to correct these notions scientifically. The effectiveness of these modules will then be tested. The participants of this study were 15 (5th and 6th grade students) from Gwangju Metropolitan City and Chonnam Province who passed a gifted student assessment test developed by J university. The student's notions about the reason only one side of the moon is visible were assessed through questionnaires, interviews, and reenactments. Instructional modules to minimize these notions were developed and then improved upon by class reenactments. And then these modules were used to teach a real class with cameras recording the students. Protocols were analyzed using this footage, and emphasis was placed on how the developed class module changed student's misconceptions. The instructional module developed in this study was: student conception assessment writing materials exploration activity stage 1 (moon's orbit) exploration activity stage 2 (moon's rotation) - exploration activity stage 3 (moon's orbit and rotation) - exploration activity stage 4 (verbalizing the moon's orbit and rotation) - exploration activity stage 5 (thinking about moon movement considering earth's rotation - exploration activity stage 6 (relating the earth and moon's movement) and verifying student conception change. An important conclusion of this study was that all 15 students had misconceptions that could be divided into categories A, B, and C. Category A could be separated with more specifics into A-1 and A-2, and C into C-1 and C-2. After the instructional module was utilized, the student categories show positive change in the following stages: Category A at exploration activity stage 1 and 2, Category B at exploration activity stage 3, Category C-1 at exploration activity stage 4 and 5, and Category C-2 at exploration activity stage 6. Category C-1 students immediately changed to Category C-2 after going through a few stages, and their misconceptions were finally corrected after going through exploration activity stage 6. The misconceptions of students in all categories were corrected scientifically after completing stage 6 education. This study proposes that a combined education of reenactments, exploration materials development, and exploration activities by stages will effectively correct misconceptions about the Earth and moon's movement.
