With five gifted and nine average elementary school students, this study attempted to make a comparative analysis on the characteristics of their scientific writings for earth science-related topics. The analysis found that all of the gifted students showed higher scores than the average in the writing sections of scientific nature, logical nature and creativity. Compared to the average scores, their creativity scores were far higher. By comparing and analyzing the predicates in the writings two groups wrote, I found that the gifted students used more sentences per topic than the average students. Both groups wrote the most numbers of sentences for Volcano-related topics. In the meantime, the gifted children used the least numbers of sentences for the related topics to atmospheric pollution and the average students did so for the related topics to fossils. By the analysis on the patterns of predicate, it was observed that both groups used material predicates most and verbal predicates least. As far as the second most used predicates are concerned, the gifted children used relational predicates and the average students used mental predicates.

The purpose of this study is to use DARTs (Directed Activities Related to text) to foster inquiry problems while actively engaging accelerated gifted elementary students in the field of earth sciences. This study is continually evolving in the classroom on the proposition that accelerate the scientific thought whether inquiry problems show any change according to the extent of prior background knowledge through DARTs. Researchers appointed the accelerated gifted elementary students with 14 investigation problems and it was their duty to not only classify the inquiry problems, but to analyze using interviewing methods according to type classification framework. Many scientific terms were used concretely in the inquiry problems that were propose after DART. The students gave a direct effect to the inquiry problem to be proposed according to the level of the content that it is presented in the DARTs worksheet. As a result, the NP-IP type and the EC-IP, NC-IP inquiry problem type proposed above much as a whole in DARTs former and prior. Particularly, the EMC-IP type and etc. was variously proposed after the DARTs. And the students proposing the inquiry problem of above average proposed the inquiry problem of the EP-IP type much unlike the general average student after the DARTs. The EC-IP, NC-IP and NF-IP type were changed much after DARTs used. Particularly, the EC-IP and NC-IP type were changed much.

This research aims to look into the mathematically gifted 6th and 7th graders spatial visualization ability of solid figures. The subjects of the research was six male elementary school students in the 6th grade and one male middle school student in the 1th grade receiving special education for the mathematically gifted students supported by the government. The task used in this research was the problems that compares the side lengths and the angle sizes in 4 pictures of its two dimensional representation of a regular icosahedron. The data collected included the activity sheets of the students and in-depth interviews on the problem solving. Data analysis was made based on McGee's theory about spatial visualization ability with referring to Duval's and Del Grande's. According to the results of analysis of subjects' spatial visualization ability, the spatial visualization abilities mainly found in the students' problem-solving process were the ability to visualize a partial configuration of the whole object, the ability to manipulate an object in imagination, the ability to imagine the rotation of a depicted object and the ability to transform a depicted object into a different form. Though most subjects displayed excellent spatial visualization abilities carrying out the tasks in this research, but some of them had a little difficulty in mentally imagining three dimensional objects from its two dimensional representation of a solid figure.

The purpose of this study was to compare the career awareness and social contribution consciousness between the elementary science gifted students and the general students. For this, survey was taken by 201 gifted students and 216 general students. Methods used are Cronbach alpha, frequency, percentage, independent t-test and Pearson's correlation coefficient. The results are as follows : 1. The gifted students have higher career awareness than the general students. The gifted students recognize their own interests, aptitudes and talents which they are concerned. 2. The gifted students have higher social contribution consciousness than the another. This shows that the gifted students have desire to be respected and positive view of social contribution. 3. There is a positive correlation between career awareness and the social contribution consciousness. According to the past studies, students' household economic status affect their view or grade which they get.. Based on these results, we suggest that a development of educational program for career awareness and social contribution consciousness which can improve gifted students' social responsibility consciousness is necessary.

In this study, the reliability and validity of the retrospective pre-post test were analyzed in order to solve the problem of traditional pre-post test including response shift bias. Samples of the study were 162 elementary school students who are studying at the S university gifted education center in Seoul. Before completion of the field trip, we conducted pre test of science-related attitudes. After completion of the field trip, respondents were asked to compare their responses of pre and post science-related attitudes to quantitatively analyze the commonalities and differences of the two tests. To find out more characteristics, qualitative data such as daily records and interview were also gathered and analyzed. The major results of the study are as follows. First, for the paired t-test, there was no statistically significant difference between separate pre-test scores and retrospective pre-test. There was a very high correlation between the separate pre-test scores and the retrospective pre-test. Second, there were significant differences in all seven sub-factors of science-related attitudes between the retrospective pre-test and the post-test. Third, the separate pre-test scores showed a slightly higher tendency than the retrospective pre-test scores. This suggests that the response shift bias appears when it is performed the separate pre-test in affective domain. As a result of the interview, it was found that the evaluation standards of separate pre-test did not match with those of post-test. Forth, internal consistency reliability of the retrospective pre-test was higher than that of the separate pre-test. However, there were significant differences in six factors of science-related attitudes excluding the 'social implications of science' between the separate pre-test and the post-test. Based on these results, the retrospective pre-post test design provides simplicity and convenience to both respondents and investigators, as it is done with one test. The retrospective pre-post test design can be regarded as a valid design for the self-report measurement of affective domain on a single experimental group.

This study analyzes the epistemic considerations and the argumentation level revealed in the discourse of the key concept of natural selection for science-gifted elementary students. The paper analyzes and discusses the results of a three-student focus group, drawn from a cohort of twenty gifted sixth-grade elementary students. Nature, generality, justification, and audience were used to analyze epistemic consideration. Learning progression in scientific argumentation including argument construction and critique was used to analyze students' scientific argumentation level. The findings are as follows: First, Epistemic considerations in discourse varied between key concepts of natural selection discussed. The nature aspect of epistemic considerations is highly expressed in the discourse for all natural selection key concepts. But the level of generality, justification and audience was high or low, and the level was not revealed in the discourse. In the heredity of variation, which is highly expressed in terms of generality of knowledge, the linkage with various phenomena against the acquired character generated a variety of ideas. These ideas were used to facilitate engagement in argumentation, so that all three students showed the level of argumentation of suggestions of counter-critique. Second, students tried to explain the process of speciation by using concepts that were high in practical epistemic considerations level when explaining the concept of speciation, which is the final natural selection key concept. Conversely, the concept of low level of epistemic considerations was not included as an explanation factor. The results of this study suggest that students need to analyze specific factors to understand why epistemological decisions are made by students and how epistemological resources are used according to context through various epistemological resources. Analysis of various factors influencing epistemological decisions can be a mediator of the instructor who can improve the quality and level of the argumentation.

As research results, male schoolchildren were found to solve problems more easily in the area of basic process skills while female schoolchildren were found to solve problems in the area of integrated process skills. Schoolboys showed the high tendency to solve problems in a planning pattern by memory, or solving pattern in which they are fully aware of the contents of both questions and choices in answer sheets, or the pattern which they are fully aware of distracters in answer sheets; in contrast, schoolgirls showed a high tendency to get a good result by analyzing both questions & choices in answer sheets or analyzing a chart, graph and illustration, which explains that female schoolchildren tend to solve problems in more diverse ways than male schoolchildren. In case of a poor achiever, male schoolchildren tend to make a failure while trying to find answers in an inadequately understood state or trying to solve on mistaken memories while doing questions immediately while female schoolchildren showed a lot of solving patterns based on mistaken memories or wrong analyses of a chart, illustration, or graph. Such results are believed to offer the implications on the understanding of male/female schoolchildren in their problem-solving pattern of their exploratory ability in elementary science and on its subsequent program development.
