Human-Robot Interaction (HRI), based on already well-researched Human-Computer Interaction (HCI), has been under vigorous scrutiny since recent developments in robot technology. Robots may be more successful in establishing common ground in project-based education or foreign language learning for children than in traditional media. Backed by its strong IT environment and advances in robot technology, Korea has developed the world's first available e-Learning home robot. This has demonstrated the potential for robots to be used as a new educational media - robot-learning, referred to as 'r-Learning'. Robot technology is expected to become more interactive and user-friendly than computers. Also, robots can exhibit various forms of communication such as gestures, motions and facial expressions. This study compared the effects of non-computer based (NCB) media (using a book with audiotape) and Web-Based Instruction (WBI), with the effects of Home Robot-Assisted Learning (HRL) for children. The robot gestured and spoke in English, and children could touch its monitor if it did not recognize their voice command. Compared to other learning programs, the HRL was superior in promoting and improving children's concentration, interest, and academic achievement. In addition, the children felt that a home robot was friendlier than other types of instructional media. The HRL group had longer concentration spans than the other groups, and the p-value demonstrated a significant difference in concentration among the groups. In regard to the children's interest in learning, the HRL group showed the highest level of interest, the NCB group and the WBI group came next in order. Also, academic achievement was the highest in the HRL group, followed by the WBI group and the NCB group respectively. However, a significant difference was also found in the children's academic achievement among the groups. These results suggest that home robots are more effective as regards children's learning concentration, learning interest and academic achievement than other types of instructional media (such as: books with audiotape and WBI) for English as a foreign language.

This study examined the effects of Literature-based Mathematical Activities using scaffolding (LMS) on the mathematical achievement, interest, and vocabulary of day care children. The experimental group of 15 boys and 15 girls was exposed to both literature and teacher's scaffolding while the comparison group of 14boys and 16 girls had traditional mathematics curriculum. The experiment was carried out for 8 weeks. ANCOVA and T-test were employed for a statistical analysis. The results revealed statistically significant differences in mathematical achievement, interest, and vocabulary between an experimental and control groups. We can conclude, therefore, that LMS is more effective in developing children's mathematical thinking abilities than a traditional mathematical curriculum.

The study examined and compared relationships among self-esteem, self-efficacy, and academic achievement of children in poverty and the comparative groups. The subjects of this study were 97 elementary school students who had benefited from the free meal project and 97 students as the comparative group who did not receive the benefit. Descriptive statistics, Cronbach's ${\alpha}$ tests, and multiple regression analysis were employed to analyze the data. The results showed that academic scores of the comparative group were statistically higher than those of children in the poverty group in Korean language, mathematics, science, and sociology. Also, self-esteem of children in the poverty group was lower than that of the comparative group's in terms of leadership and popularity. The poverty group also showed lower self-efficacy in self-regulated efficacy tasks. Finally, multiple regression analysis demonstrated that different sub-factors of self-esteem and self-efficacy predicted the academic achievement of children in poverty group and the comparative groups.

This study examined different individual, family factors and classroom environment that affect children's perceived competency. For an analysis, achievement motivation, intrinsic locus of control and anxiety were included in individual variables. For family factors, parental support and marital conflict were examined. For classroom psycho-social environment, teacher support, peer relations, classroom involvement and teacher control were used. The sample consisted of 565 fifth and sixth grade children. Statistics and methods used for the data analysis were Cronbach's alpha, Factor analysis, frequency, percentage, t-test, Pearson's correlation, and Hierarchical Regression. Several major results were found from the analysis. First, boy's perceived academic competency was higher than girl's. And no sex difference was in children's social and athletic competency. Second, boy's and girl's perceived academic and social competency and boy's perceived athletic competency had a positive correlation with achievement motivation, intrinsic locus of control, parental support, teacher support, peer relations and classroom involvement. And girl's perceived athletic competency had a positive correlation with achievement motivation, intrinsic locus of control, parental support and peer relations. But boy's and girl's perceived academic and social competency and boy's perceived athletic competency had a negative correlation with anxiety and parental marital conflict. Third, the most important variable predicting boy's and girl's perceived academic competency was achievement motivation. The most important variable predicting boy's and girl's perceived social competency was peer relations. And the most important variable predicting boy's perceived athletic competency was peer relations. On the other hand, the most important variable predicting girl's perceived athletic competency was father's support.

The purpose of this study is to understand the school achievement of domestic adopted children in Korea and its related factors. Although the developmental outcomes of domestic adopted children were the focus of research interests, their school achievement has never been fully addressed in Korea. The subsample (9-17 years old) of 5th wave data of was used for the analysis. The results showed that the school achievement level of domestic adopted children was not significantly different from their non-adopted peers during elementary school years except the mathematics, but changed drastically after they entered the middle school, showing significantly lower level from their non-adopted peers. Factors related with the overall school achievement were the level of school, maternal education, age at adoption, child's self-esteem and school adjustment. For specific subject, however, significant factors were found to be somewhat different. Based on the results of the study, the practical guidelines to improve the school achievement of adopted children were suggested. Also, suggestions for the following studies were made.

The purpose of this study was to examine the effects of the environmental factors and the family structure on the academic achievements of their children. Among various environmental factors, the family income, the affective relationship between mother and child, and the mother's educational involvement are considered. Total of 164 mothers with children attending elementary school completed the structured questionnaires. The degree of educational involvement of single mothers was lower than that of mothers of both parents families. In order to analyze factors that affect children's academic achievement, the path regression was performed. The family income and the mother-child affective relationship were found to have indirect effects on the academic achievements of elementary school students through maternal involvement in their children's education.
