The test for the identification of verbally gifted children was administered to 323 gifted and average primary school children. Listening, reading, writing were analyzed by statistical methods, and speaking was videotaped for analysis of the interview and discussion process. Cronbach's ${\alpha}$ confirmed reliability of the test. There were significant correlations between item scores and total scores. Concurrent validity was indicated by correlations between total scores and language arts scores. The test showed differences between the gifted and average children in reading and writing scores for the 2nd and the 3rd graders, and in listening and reading scores for the 4th, 5th, and 6th graders. Analysis of speaking ability showed that the gifted children expressed their ideas more logically and creatively than the average children.

This study was conducted in order to model the relationship between children's ego strength and their school adjustment and life satisfaction levels. For this purpose, 4,765 4th-6th grade elementary school children were surveyed by means of a questionnaire. The collected data were analyzed by means of structural equation modeling. The results of this study may be summarized as follows. First, in all the grades, a significant and positive correlation was observed between the children's ego strength and their school adjustment and life satisfaction levels. Second, ego strength was found to be a variable that had a significant effect on life satisfaction indirectly through the medium of school adjustment. Third, the relation model between the variables differed according to grade. That is, the direct effect of ego strength on life satisfaction was stronger in the high grades, and the level of school relationship adjustment was found to have a significant effect on family relationship satisfaction as a factor of life satisfaction in 4th graders, whereas it did not in the case of 5th and 6th graders.

The study examined BMIs, physical strength, activities, and the attitudes and behavior toward weight control among 7,968 Korean students{2,435 5th graders from elementary schools(ESs), 2,524 2nd graders from middle schools(MSs), 2,739 2nd graders from high schools(HSs)} nationwide. Compared to the 1987 data, there were increases of height(3-6cm) and weight(3-8kg), but decreases of physical strength and exercise. Lack of 'regular exercise' among girls from MSs and HSs and higher proportion of time spent on watching TV and using a computer for elementary schoolers were particularly noticeable. Proportions of students who were satisfied with their body weight were 49% for ESs, 35% for MSs, and 29% for HSs. There was no relationship between subjective and objective evaluations of body weight. Diet rather than exercise was more frequently chosen as a method of weight control. Compared to boys, girls showed stronger association between the amount of exercise and the subjective body weight in MSs and HSs, however this association was not found for the subjects from HSs. Values for the 50th percentile of BMI of boys and girls were 18.4 and 17.7 for ESs, 19.9 and 20.1for MSs, and 21.4 and 20.6 for HSs. In MSs and HSs, boys with BMI between 15th to 85th percentiles were physically stronger than those whose BMIs were lower than 15th kor higher than 85th percentiles. For the other groups, there was a trend of a positive relationship between BMI and physical strength. Based on the analyses of BMI and physical strength, this study suggests 22 and 21 for upper grades in ESs, 24 and 23 for MSs, and 27 and 25 for HSs as the respective cut off points of BMI for weight control n boys and girls. A need for implementing nutrition education program focused on weight control is also suggested.

Objective: This study examined the effects of grandfathers' positive parenting behavior, and fathers' positive parenting behavior on school-age boys' school adjustment. Methods: A total of 217 5th and 6th grade male elementary school students (126 5th graders and 91 6th graders) and their fathers living in Seoul and Gyeongnam province participated in the study. The data were analyzed using correlations, and structural equation modeling. Results: Grandfathers' positive parenting behavior indirectly influenced boys' school adjustment through their fathers' positive parenting behavior. It means that fathers who perceived their fathers' parenting behavior as more positive showed a higher level of positive parenting behavior, which led to a more positive school adjustment for their sons. Conclusion/Implications: These results uncovered the pathways from grandfathers' positive parenting behavior to school-age boys' school adjustment through their fathers' positive parenting behavior in an aspect of the intergenerational transmission of parenting. In addition, these findings have implications for future research of developing intervention programs for school-age boys' school adjustment and parent education programs to facilitate fathers' positive parenting behavior for school-age children's school adjustment.

Purpose: The purpose of this study was to identify influences of child-rearing attitude and parent-school age communication on self-efficacy of 5th and 6th graders. Methods: Data were collected using questionnaires from 460 5th and 6th graders in S city. The data were analyzed using SPSS WIN program. Results: There were significant differences in child-rearing attitude according to gender, mother's level of education, perceived atmosphere and religion. Self-efficacy was significantly correlated with school record, family income, mother's level of education, father's level of education, and perceived atmosphere. There were significant differences in communication with father according to father's level of education, and perceived atmosphere. Communication with mother was significantly correlated with father's level of education, mother's level of education and perceived atmosphere. The relative influence toward the children's self-efficacy shown in the order of importance was as follows; child-rearing attitude, school record, communication with mother, communication with father, father's level of education, family income. Conclusion: From the study, self-efficacy appears to be influenced by multiple factors such as child-rearing attitude, school record, communication with mother, communication with father, father's level of education, and family income.

This study examined the development of children's perceptions of popular and unpopular peers. Subjects were 784 children in kindergarten, $2^{nd}$, $4^{th}$, and $6^{th}$ grades. Research findings were that : (1)socio-metric popularity and perceived popularity correlated positively with athletic ability, academic ability, and prosocial behavior. Whereas two subtypes of aggression(physical aggression and relational aggression) correlated negatively with sociometric popularity, perceived popularity correlated positively with relational aggression in 6th grade. (2)Social behaviors consistently emerged across developmental periods as predictors of popularity. (3)Academic ability was an important characteristic of popular children. (4)Teachers' praise and punishment affected popularity in kindergarten and $2^{nd}$grade children, but peer effect was more important for $4^{th}$ and $6^{th}$graders.

Programming education has the favorable influence on creative logical thinking and problem-solving ability of students. However programming has not been actively taught at the elementary schools. One of the causes is the lack of systematic curriculum. In this paper, we design the curriculum for 'Understanding of Information Processing' in revised ICT educational guidelines using the educational programming language Scratch. We propose curriculum that consists of 4 lessons for 1st and 2nd graders, 5 lessons for 3rd and 4th graders, and 6 lessons for 5th and 6th graders to lesson the cognitive load, and present the instruction plans. Selected group of experts verified our proposed curriculum and instruction plans. According to verification results, we can conclude that almost the area including the targets, educational factors, learning content, amount of learning, instruction plans are appropriate. The curriculum proposed in this paper can help the elementary students learn programming efficiently, and develop their logical thinking, problem-solving ability, creativity, and information processing ability.

The purpose of this study was to examine the differences between aggressive and nonaggressive boys with the use of a social information processing approach. The subjects were 80 3rd & 6th grade boys selected from a public elementary school in Seoul. The subjects were interviewed individually. Following the presentation of each story, five questions were asked. A 2 x 2 Analysis of Variance was performed for each of the 5 dependent measures. Results showed (1) Aggressive boys were more likely to attribute a hostile intention to the behavior of peer. (2) Aggressive boys predicted their own response as more hostile and aggressive. (3) The 6th graders generated more alternative solutions than the 3rd graders. (4) Non significant results are not reported in the abstract. (5) Aggressive boys were likely to choose an ineffective solution.

The psychometric properties of a preliminary version of the Friendship Quality Scale(FQS) were examined with data collected from 300 3rd and 5th grade children. Scores on the Self-Perception Scale were obtained to examine convergent validity. The FQS assesses friendship quality in 9 sub-scales, inclusive of 6 friendship functions. Factor analysis confirmed the 9 sudscale structure of the FQS for 5th graders, but 4 friendship functions instead of 6 were a better fit for 3rd graders. Except for one, the sub-scales showed relatively high internal consistency ; Cronbach ${\alpha}$ ranged from .70 to .93. Convergent validity was indicated by correlations between self-perception and sex differences in friendship functions. Friendship functions and satisfaction were related to self-perceptions in social acceptance, behavior, and global self-worth. Girls reported higher friendship functions and satisfaction in friendship than boys.
