The purpose of this research is to find out if it is possible to apply the Waldorf School's mathematics education method to Korean alternative schools which are run under the national curriculum. To achieve this, the researcher conducted class on geometry for three weeks with ten 7th graders(four girls and six boys) from Apple Tree Waldorf alternative school in Busan, which has adopted Valdorf education courses. For the first two weeks, the class was about 'fundamental geometrical construction', and then it was evaluated. On the third week, the lesson was on plane figures, followed by a test with 9 plane figure questions that are based on general middle school mathematics curriculum. The result shows that most of the students understood 'fundamental geometrical construction'. When it comes to the test on 'plane figures', seven students got 8 out of 9 right, two students got 6 out of 9 right, and one of them had difficulty solving the questions. According to the results of this research, it is thought that there will be no problem for students to understand mathematical concept even if the Waldorf School's mathematics education method is applied to Korean alternative schools. Also, the Waldorf School's mathematics education method is considered to be a good teaching model for the Korean mathematics curriculum which places emphasis on 'mathematical creativity' in regard to the curriculum and contents.

This study examined how a Structured Reading Framework (SRF) is related to improving students' critical thinking ability in an argument-based inquiry approach, called the Science Writing Heuristic (SWH) approach. A total of 75 $8^{th}$ graders participated in the study, with 34 in the control group and 41 in the treatment group. The gains in critical thinking skills were compared between two groups, and relationships among the components of the reading framework and the critical thinking skills were explored at the group level. Result indicates that the treatment group who used the SRF had larger gains in critical thinking scores than control group who used the Original Reading Framework (ORF). In addition, results show that the correlations between Reading Framework (RF) components and critical thinking scores are statistically significant in the treatment group, while no correlations exist in the control group. It appears that using the SRF have an impact on developing students' critical thinking ability by providing a scaffold to assist argumentation practice.

This study investigated the relationships between parental marital conflict, attachment to parents and peer relationships. The mediating role of attachment to parents was also explored in the relationship between parental marital conflict and peer relationships. Two hundred eighty four 8th graders participated in this study. The participants answered questionnaires regarding parental marital conflict, attachment to parents, qualify of their friendship, and attachment to peers. The main results of the study are as follows: First, adolescents who perceived a higher level of parental marital conflict reported less positive feelings and more negative feelings toward their friends. They also reported lower peer attachment, and tended to perceive their friendship functions negative. Second, adolescents who showed stronger attachment to their parents reported more positive feelings and less negative feelings toward their friends. They reported higher peer attachment, and perceived friendship functions positively. Third, adolescents who perceived a higher level of parental marital conflict showed weaker attachment to their parents. Finally, attachment to fathers and mothers mediated the association between parental marital conflict and peer relationships. In other words, parental marital conflict had an indirect effect on peer relationships. The results suggest that attachment to fathers and mothers that resulted from parental marital conflict played an important role in determining peer relationships among adolescents, rather than the existence of the parental marital conflict itself.

The purpose of this study was to examine nutrition management conditions of lunch with the elementary schools and middle schools in the Changwon area. 292 students (5th and 6th graders) from three elementary schools and 330 students from three middle schools (boys, girls, and co-ed) participated in the aggregate selective plate waste measurement for 5 days. Planned menus, serving sizes and plate waste amount data were collected. Nutrient analyses for the planned, served and consumed menus at school lunches were performed by using CAN-PRO 3.0. Nutrient analyses of the planned, served and consumed menus were compared with nutrient management standard (former edition) for school lunch and 1/3 Korean Dietary Reference Intakes (KDRIs). Significant difference was found in the average consumption rate between the elementary schools (82.2%) and the middle schools (71.8%). Specifically, the consumption rates of steamed rice (p < 0.001), side dish 1 (p < 0.001), and Kimchi (p < 0.01) at the middle schools were significantly lower than those of the elementary schools. When the nutrient contents in the served menus were put into percentages to the nutrient contents in the planned menus, middle schools (92.3%) showed bigger serving loss than the elementary schools (95.4%). In the nutrient assessment comparied with nutrient management standard (former edition), middle school lunches showed comparatively less energy or less some nutrient contents against the standard than the elementary school lunches. Specifically, in case of boys in middle schools, Vitamin C was the only nutrient content that satisfied the standard in the planned menus, served menus and consumed menus. In the 1/3 KDRIs based assessment, middle schoolers were found not to be provided proper nutrients with school lunches. To improve nutrition management at middle school foodservices, dietitians should reinforce nutrient assessment for menu planning, and try to decrease serving loss and plate waste.

In this study, the influence of mothers' parenting behaviors on children's strategies and competence of emotional regulation was examined. Further, the mediating effects of children's active-social support seeking and aggressive strategies on the above relationship were explored. The participants were W mother-child pairs. The children were 5th and 6th graders at two elementary schools in Kyunggi province and Kwangju metropolitan area The data were analyzed with descriptive statistics, factor analysis, Cronbach's alpha, Pearson correlations, standard multiple regressions and structural equation modeling analysis by LISREL 8.3. The main results of this study were as follows: (1) The more the mothers coached children with affection and reasoning, the more adaptive emotional regulation the children had; whereas children tended to have maladaptive emotional regulation in response to the mothers' rejecting and forceful parenting behaviors. Also, when children were coached by mothers with love, reasoning and consistent restriction, they used more active-social support seeking strategies, whereas they used more aggressive strategies when the mothers coached children with rejecting and forceful parenting behaviors. The more the mothers were rejecting, forceful and intervening, the more the children used passive-avoidant strategies. (2) The more the children used active-social support seeking strategies and the less the children used aggressive strategies, the more likely they had adaptive emotional regulation. The more the children used aggressive strategies, the more likely they had maladaptive emotional regulation. (3) Children's active-social support seeking strategies played a partial mediating role between mothers' affectionate and reasoned coaching and children's adaptive emotional regulation. These strategies, on the other hand, played a full mediating role between mothers' consistent restriction and children's adaptive emotional regulation. Children's aggressive strategies played a partial mediating role between mothers' rejecting and forceful parenting behaviors and children's maladaptive emotional regulation. Mothers' non-intervention had an influence on neither the children's aggressive strategies nor their maladaptive emotional regulation.

This study aimed to examine the effect of parentification on the smartphone dependency of upper elementary school children in double-income families and to verify whether ambivalence over emotional expression and loneliness sequentially mediates the relationship between parentification and smartphone dependency. The participants were 311 upper-elementary school students (4th to 6th graders; 126 boys, 40.5%) in doubleincome households residing in Seoul, Gyeong-gi, and Incheon. The data were collected through an online self-report questionnaire completed by the participants and were analyzed using SPSS 26.0 and Mplus 8.7 software. The results can be summarized as follows. Firstly, the direct effect of parentification on the smartphone dependency of the children from double-income families was statistically insignificant. Secondly, ambivalence over emotional expression mediated the effect of parentification on smartphone dependency, while loneliness did not. Lastly, parentification influenced smartphone dependency through the sequential mediating channel of ambivalence over emotional expression and loneliness. In conclusion, these findings indicate that interventions for smartphone-overdependent children from double-income families should place emphasis on children's psychological difficulties attributed to parentification. Specifically, this study highlights the importance of alleviating the levels of ambivalence over emotional expression and loneliness to address the issue of children's smartphone dependency in double-income families, suggesting possible involvement and support at both household and societal levels.
