In Korea, pre-service teachers' negative attitude toward robots keep them from being applied in schools. To cope with these obstacles, this study examines the change of pre-service teachers' attitude toward robots after adopting robot programming. To prove the program's effect, pre-service teachers were divided into three groups, including each group taking pre-and post-tests. After analyzing the pre-tests, none of the groups showed any difference; however, they did show significant differences in the post-tests. A paired sample t-test was conducted in each group for investigating the change. Those who took ICT and programming education did not show a change. However, those who took robot programming education did show a statistically significant difference.

In this study, we investigate social preference of gifted students by analyzing their behaviors in social dilemma situations. We conducted an experimental study using ultimatum games and public goods games with 132 academically gifted middle school students who attended the Ewha-Seodaemun Center for gifted education from 2012 to 2016. We also experimented the same games with 87 regular students for comparative analysis. The result of ultimatum game experiment shows that there is no statistical difference in the proposed share of both groups. Their proposed share ranges from 37% to 38% as expected in other similar studies. However, the rejection rate of the respondents to the proposals with small share are significantly higher among gifted students than among their regular counterparts. This result implies that the gifted students show stronger negative reciprocity, meaning that they tend to punish selfish behaviors even when it takes some costs. In finitely repeated public goods game experiments, the results show that both groups' contribution rates decrease toward the end of the experiments. However, the gifted students show strategic cooperation by attempting to increase the other members' contribution rate within an experimental group. This implies that gifted students tend to care more about how to increase their own expected rewards by reciprocating other students' behaviors.

The purpose of this study is to investigate the effects of educational context variables on achievement and interest in mathematics in high and low achieving students in Korea. Students participated in TIMSS 2015 in Korea were divided into two groups according to their achievement in mathematics. And the effects of educational context variables on achievement and interest in mathematics were analyzed in each group using the Hierarchical Linear Model(HLM). Main findings of this study are as follows. First, variables which influence achievement also influence interest but any variables which influence interest don't influence achievement in upper-group students. Number of Books and Students' Perceived Mathematics Lessons have strong influence on achievement and interest in both fourth and eighth grade students. Second, variables which influence achievement or interest in mathematics in lower-group also influence achievement or interest in mathematics in upper-group students. But any variables which influence achievement or interest in upper-group students don't influence achievement or interest in lower-group students. For examples, Parents' Education, Students' Perceived Mathematics Lessons have effects on upper-group students' achievement. Number of Books, Home Learning Environment, and Numeracy Activities Before School have significant effects on the achievement of fourth grade students. Students' Perceived Mathematics Lessons is the variable that influence on the interest of both fourth grade and eighth grade students. This study suggests the ways to improve mathematics teaching and learning based on these results.

The purpose of this study is developing the manifestation process model of group creativity among mathematically gifted students. Therefore, I designed the manifestation process model of group creativity by researching the existing literatures on group creativity and mathematical creativity. The manifestation process model of group creativity was applied to mathematically gifted students' class. By analyzing students' response, the manifestation process model of group creativity was improved and concretized. In conclusion, the process of a combination of contributions was concretized and the major variables on group creativity such as a diversity, conflict, emotionally supportive environment and social comparison were verified. In addition, some reflective processes was discovered from a case study.

The purpose of this study is making the career education program related to the subject, Manual Training and Home Economics, to present the effective guidance and to improve career maturity of students about the unit, "Making a choice of career and Job ethics" of middle school senior's course. In order to estimate this program, 60 students of 2 classes were chosen as research subjects among middle school seniors and each of classes was divided into two groups, an experimental group and a control group. After the experimental group was trained the career education program related to Manual Training and Home Economics for 15 sessions, the effect was verified by comparing tests before and after program execution. In order to prove effects of the program. Each grade of both the experimental group and the control group was taken analysis of covariance (ANCOVA). Result of the program experiment is following. First, after executing the career education program related to Manual Training and Home Economics to the experimental group, participants showed that both attitude and ability for career maturity were improved in each sub-factor field of the career maturity as a result of tests before and after program execution. Second, in program satisfaction estimation, most of students had a positive attitude and in every time satisfaction, they made high estimation on the program, especially including the proper level of students and interesting activities. Finally, the final program was completed based on the result of effect analysis of the program.

The purpose of the present study was to analyse the effectiveness of a gifted education program. To analyse the effectiveness of an education program for the gifted affiliated with a university, the study carried out a quasi-experimental design to compare the 153 gifted students who enrolled in an education center for the gifted and the 131 potentially gifted students who were nominated by teachers for their high achievements and interests in science but without any education services for the gifted. These two groups of students were compared in the aspects of problem finding ability in science, motivation, self regulation, science-related attitudes, and science anxiety through the pre- and post-treatment settings. The results indicated that the gifted group showed a significant improvement in originality and elaboration of problem-finding ability, but the potentially gifted group showed significant decrease in most variables of problem finding. Related to motivation and self-regulated learning, gifted students showed an increase in cognitive strategy use and decrease in intrinsic value, but the potentially gifted students showed significant decreases in most variables related to motivation and self-regulation, except intrinsic value. Related to the scientific attitudes and science anxiety, there were no significant changes between pre- and post-tests in the gifted group, but significant decreases in most variables were found in the potentially gifted group. The results of paired t-test and Ancova indicate that significant differences between the gifted and the potentially gifted groups are mainly due to the significantly lowered performance in post tests in the potentially gifted group, rather than a significant increase in gifted group.

The purpose of this study was to develop and apply the elementary teacher training course for educational programming language based on TPACK in order to make elementary school teachers fully equipped with teaching efficacy for SW education. As a result, the informatics teaching efficacy of the teachers in the experimental group who participated in EPL training course developed based on TPACK was statistically more significant than the teachers in the control group(t=4.13, p<.001). The dependent sample t-test of the experimental group showed a statistically significant increase with t=4.57 (p< .001). It proved that TPACK-based teachers' training course is effective to improve teachers' informatics teaching efficacy. It is suggested that the development of SW education teacher training course should be systematically structured considering TPACK framework.

In this paper, we analyzed to find out the effects of phonological awareness game using teacher assisted robot on 5-year-old children's reading ability and reading interest. A total of 30 5-year-old children were equally divided into two groups: the experimental group and the control group. The experimental group conducted a total of 16 game activities using an educational robot twice a week for three weeks, the control group conducted the same 16 game activities without the robot during the same period. The results are as follows. Firstly, the experimental group was better in reading ability than that of the control group, especially total scores, word meaning, omission, and replacement. Secondly, the experimental group showed more interest in reading than the control group. From these findings, it can be suggested that phonological awareness games using the educational robot lay foundation to developing and enhancing on 5-year-old children's reading abilities and interest in reading.
