This study investigated elementary students' (grade 4~6) learning progressions for water cycling drawn from iterative assessments using ordered multiple-choice (OMC) items. An assessment system, which consisted of construct map, item design, outcome space, and measurement model, was employed in this study to examine children's learning progressions. At the first stage of the assessment system, a construct map was designed on which children's conceptual understandings from naive to most sophisticated were represented. At the item design stage, 8 OMC items were drawn from the construct map. Each item option of the OMC items was scored from 0 to 3 according to its level of understanding at the stage of outcome space. As a measurement model, Rasch model, a branch of item response theory, was applied to interpreting the outcomes of the OMC items. This cycle of assessment system was furtherly implemented iteratively in order to elaborate on the first version of water cycling learning progression. In conclusion, children's understanding of water cycling could be described in two aspects: water distribution and water movement. We identified children's conjectural developmental pathways about water cycling existed from superficial and naive accounts to more complex and abstract accounts.

This study investigated the causality of the children's self-perceived competence and related variables(age, sex, socio-demographic variables, family structure, the number of brother, home environmental process variables and peer group environmental variables.) The subjects of this study were 842 children at age five, seven, nine, eleven and thirteen attending kindergartens. elementary schools and junior high schools and their mothers in Seoul. This study employed children's self-perceived competence scales(The Pictorial scales for 5, 7, Qestionnaire for 9, 11, 13) home environment scales and peer group enviornment scales(the Pictorial scales for 5, 7 Qestionnaire for 9, 11, 13) Freqencies one way-ANOVA Pearson's Cronbach's αmultiple regression and path analysis were used for data-analysis. Major findings were as follows: 1. The results of the analysis of causal model showed that the variables that affected cognitive self-perceived competence directly were age, sex, parent's education economic status of the home the number of brother and peer's emotional support 2. The results of the analysis of causal model showed that the variables that affected social self-perceived competence directly were sex, economic status of the home, peer's emotional support and common activity. 3. The results of the analysis of causal model showed that the variables that affected physical self-perceived competence directly were age, sex, peer's emotional support and common activity.

This study examines the relationship among children's smart device immersion tendency, children's self-regulation, and pro-social behavior as well as investigates the mediating effect of self-regulation between children's smart device immersion tendency and pro-social behavior. Participants were composed of 263 4-year-old children attending kindergarten in Incheon and Gyeonggi province. Data were analyzed by means of Pearson's correlation coefficients in SPSS, the structural equation model and bootstrapping in AMOS. The results are as follows. First, there is a statistically meaningful relationship among children's smart device immersion tendency, self-regulation, and pro-social behavior. There is a negative correlation between children's smart device immersion tendency and children's self-regulation as well as pro-social behavior; however, there is positive relationship between children's self-regulation and pro-social behavior. Second, children's smart device immersion tendency had a direct effect on children's self-regulation. In addition, children's self-regulation indicated a direct effect on children's pro-social behavior. Third, children's self-regulation was found sufficient to mediate the relationship between children's smart device immersion tendency and pro-social behavior. The results indicate that the effort to increase children's self-regulation may decrease the negative effect toward children's pro-social behavior caused by smart device immersion tendencies.

The main purpose of this study is to examine the effects of the fathering practice on children's sociality. The subjects of this research are 569 (grade 6) students who are from 4 elementary schools, and 511 (grade 3) students who are from 4 other middle schools in Seoul and Gyeonggi province. The data was collected using two kinds of questionnaires: Canfield's (1995) Fathering Practice Scale and Urn Guy-Sung's (1999) Children's Sociality Scale. The data was analyzed by frequency, mean, standard deviation, percentage, Cronbach's alpha, t-test, one-way ANOVA, Scheffe's post hoc test, and hierarchical regression. The major results of this research are summarized as follows: First, there were differences in children's sociality according to children's and fathers' perceptions of the fathering practices. I classified 1080 students into 4 groups by mean${\pm}$1/2standard deviation of the children's and fathers' perceptions of the fathering practices. The results showed that children's sociality tends to be higher when the children's perceptions of the fathering practice are at a high level (Group 1 and Group 2), compared to when the fathers' perceptions of the fathering practice are at a high level (Group 3 and Group 4). Second, hierarchical regression was divided into two models so as to know how the effects were different from the children's and fathers' perceptions of the fathering practice on children's sociality. In the first model, only the fathers' variables were inputted and fathers' perceptions on fathering practice has significant effects on children's sociality. In the second model, both the children and fathers' variables were inputted into analysis. The fathers' perceptions of the fathering practice were not influenced, but children's perceptions of the fathering practice had great effects on children's sociality. Third, as the result of hierarchical regression with age, mid-childhood has significant effects on children's perceptions of the fathering practice on children's sociality. In addition, early adolescence is an important variable in the effects of the fathers' perceptions of the fathering practice on children's sociality. As a result the fathers' perceptions of the fathering practice are important and influential variables on children's sociality. In the result of this study fathering practice is necessary in children's development.

Emotion is a central feature of social interactions. In this study, we examined age-related changes in emotion expressiveness and emotion knowledge and how young children's emotion expressiveness and knowledge were related. A total of 300 children attending a daycare center contributed data for the study. Observation and interview data relevant to measures of emotion expressiveness and knowledge were collected and analyzed. Both emotion knowledge and expressed positive affect increased with age. Older preschool children expressed positive affect more frequently than did younger preschoolers. Older preschool children also labeled, recognized, and provided plausible causes mores accurately than did younger preschool children. In addition, we tested whether children's errors on the free labeling component conform to the structural model previously suggested by Bullock and Russell (1986) and found that preschool children were using systematic strategies for labeling emotion states. Relations between emotion expressiveness and emotion knowledge generally were not significant, suggesting that emotional competence is only gradually constructed by the child over the preschool years.

The present study surveyed both the parents of 130 children with psychopathology and the parents of 240 normal children. children were between 2 and 12 years of age. No differences were found between parents in self-differentiation or in family function by type of disorder. Parents of children with psychopathology were lower than parents of normal children in self-differentiation; this was particularly evident in cognitive function-emotional function, and emotional cut-off. Patents of children with psychopathology were lower than parents of normal children in terms of family function. Multiple regression analyses indicated that parent's self-differentiation, children's psychopathology, and parent's education level had a significant influence on family function. The regression model explained 52% of the variance.

The purpose of this study was to investigate the mediating effect of self-efficacy on the relationship between fathers' child-rearing attitude and children's prosocial behavior. The participants were 410 children aged 3-6 years, who completed scales of the fathers' child-rearing attitude, children's prosocial behavior, and self-efficacy. The data were analyzed in terms of a hypothesized structural equation model using AMOS 7.0. The results were as following. Firstly, the fathers' child-rearing attitude was found to have a direct effect on children's prosocial behavior and self-efficacy. Secondly, children's self-efficacy was also found to affect children's prosocial behavior directly. Thirdly, children's self-esteem have a mediated effect on the relationship between fathers' child-rearing attitude and the children's prosocial behavior.

This research investigated the moderating effects of children's negative emotionality, activity and sociability on the relation between maternal parenting stress and children's behavior problems. Participants consisted of 1,667 preschool children from the fifth wave of the Panel Study on Korean Children. EAS was used to measure the children's temperament. Mothers reported parenting stress and children's behavior problems. The results revealed that the magnitude of association between relation between maternal parenting stress and children's behavior problems was greater for high levels of negative emotionality and activity as well as low levels of sociability. The results support a diathesis-stress model in which high negative emotionality, activity and low sociability confer vulnerability for preschool children in a high stress family.

This study was to investigate the relationships between stress coping strategies, emotion regulation ability and behavior problems with children from low-income families and middle-income families. Subjects were 171 children from low-income families and 228 children from middle-income families, 4th - 6th grade in elementary school. The major findings are followings: (1) The level of emotion regulation ability in children from low-income families was lower and active stress coping strategies were less than children from middle-income families. In the behavior problem, children from low-income families were higher than children from middle-income families. (2) The stress coping strategies(active/ social support) in children from low-income families were related with internal behavior problem(anxiety /withdrawal). And the emotion regulation ability was related to the children's behavior problem. (3) Regression analysis model showed that emotion-regulation ability was the most influential factor to the children's behavior problem, and children from low-income families with aggressive coping strategy showed hyperactive behavior problem. So, the education/therapy programs for children from low-income families have to be developed and practiced in schools, local children centers and so on.

Purpose: This structural model study was constructed and verified a hypothetical model to examine the effects of parenting stress, social resources, family resources, and positive coping on resilience among mothers of children with developmental disabilities. Methods: Data were collected using self-report structured questionnaires, from October 19 to October 30, 2018, with 214 mothers caring for children with developmental disabilities under the age of 20 years. Results: In the fitness test results of the hypothesis model, with the fit index 𝛘² (p) = 69.27 (< .001), and the normed fit indices (𝛘² = 1.87, GFI = .94, CFI = .97, NFI = .93, and TLI = .95, RMSEA = .06, SRMR = .06), this study satisfies the good fitness in standards. There are seven statistically significant paths among the 10 paths set in the hypothetical model. The explanatory power of parenting stress and social resources, which affects the family resources was 41.4%, the explanatory power of parenting stress, social resources, and family resources affecting the positive coping was 58.9%, and the explanatory power of parenting stress, social resources, family resources, and positive coping affecting resilience was 55.5%. Conclusion: Positive coping, family resources, and social resources of mothers of children with developmental disabilities directly affect their resilience, and parenting stress indirectly affects it. Therefore, to improve the resilience of mothers of children with developmental disabilities, it is necessary to develop a systematic nursing intervention that considers parenting stress, social resources, family resources, and positive coping.
