The purpose of this study is to analyze some Korean elementary pre-service teachers' Mathematical Knowledge for Teaching(MKT). For this purpose, we selected the MKT items on number and operations which were adapted for Korean in-service teachers by Lee(2011). The survey consisting of those items was administered to 76 Korean elementary pre-service teachers at Teachers College, J University. The results are the following: First, the respondents, elementary pre-service teachers, showed that the preference for the MKT items was very affirmative, but the percentages of correct answers to the MKT items weren't generally high. Second, the preference for the instructional consultation by experienced teachers was very affirmative. Third, the percentages of correct answers to KCS, SCK, CCK and KCT were 70.13%, 55.71%, 43.87% and 29.27%, respectively. Fourth, the percentages of correct answers to type 5, 6, and 7 were more than 60%, but those of correct answers to type 1, 2, 3, 4, and 8 were less than 60%. This means we need to strengthen type 1, 2, 3, 4, and 8 in education of elementary mathematics subject at Teachers College of J University.

Although social work values are stressed among social work educators as well as practitioners, empirical studies on values have been very scarce. The objective of this study is to validate a Korean Version of the Professional Opinion Scale(POS). The Korean version was validated with a sample of 325 social worker working in various types of social work agencies. A series of confirmatory factor analysis suggested that 8 items be removed, resulting in 32 items with 4 factors. The Korean version has the same factor structure as the original version of the POS reported by its developer. The Korean version of the POS are found to be a reliable and valid instrument for measuring social work values. However, validation with more representative samples is needed to improve the quality of the Korean version of the POS.

This study verified the reliability and validity of the Korean version of the Student Career Construct Inventory(K-SCCI) that was translated into Korean language from the Student Career Construct Inventory (SCCI) developed by Savickas et al.(2018). To achieve this, this study conducted item content analysis, exploratory factor analysis, confirmatory factor analysis, and criterion-related validity in 530 university students. As a result of item content analysis and exploratory factor analysis, it was found that 4 factor models and 18 items were the most appropriate in K-SCCI. The 4 factors were named as crystallizing a vocational self-concept, exploring to gather information about occupations, deciding to commit to an occupational choic, and preparing to implement that choice. As a result of confirmatory factor analysis to verify the goodness-of-fit of the 4 factor models, it appeared to be appropriate. As a result of analyzing the correlation with related measures to verify the criterion-related validity of measures, it was found that student career construct was negatively correlated with employment anxiety but positively correlated with career adaptability.

The purpose of this research is to find out whether children's self-efficacy can be improved by sensory activities devised to encourage spirituality. The survey involved 36 children aged 4 to 5. To measure the subjects' self-efficacy, Jeon Inok(1996)'s tool was used. The 18 members of the experimental group attended a program which was dedicated to promoting spirituality by using sensory activities. The program was administered three times a week for four weeks, totaling 12 sessions, each of which contained a type of activity and lasted about fifty minutes. To the 18 members of the control group, the standard child care curriculum was applied. The levels of the subjects' self-efficacy were measured twice, both in the same way, before and after the children participated in the program. The finding reveals that the program which was designed to boost children's spirituality through sensory activities has positive effect on children's self-efficiency - cognitively, socially, emotionally, and physically. The self-efficiency level in the experimental group significantly increased by t=7.17(df=34, p<.001) compared to the control group. So, it can be said that the program dedicated to improving spirituality using sensory activities is more effective than the standard child care curriculum.

The purpose of this study was to analyze epistemological beliefs in science as perceived by elementary school students and to examine the purpose of science, the nature of scientific knowledge, the source of scientific knowledge, and the role of experimentation. The subjects of this study were 99 elementary school students. As a tool for examining epistemological beliefs in science, we used adapted questionnaires comprising elements constituting epistemological beliefs, as proposed by Elder (1999). The results of the analysis are as follows: First, in terms of the purpose of science, sixth graders had the most modern beliefs compared to other grades. Second, a statistical significance was found between fourth graders and students in other grades based on the analysis of the nature of scientific knowledge. Third, there was no significant difference in each grade's beliefs concerning the source of scientific knowledge or the role of the experiment.

This study, the Fear of Missing Out Scale (FoMO Scale) developed by Przybylski et al. (2013) was adapted and validated to the Korean culture. 3-factors were constructed through EFA and item content analysis. In the CFA, 3 models were constructed to verify the fit of the model. Compared the goodness of fit, 3-factors model with 8 items proved to be the most appropriate. Sub-factors extracted through the characteristic context and rationale of Korean culture are 'belonging needs', 'extrinsic motivation', and 'relative deprivation'. K-FoMO scale and the reliability level of each sub-factor were good. Convergent validity was assessed by significant correlation the K-FoMO scores with life satisfaction, positive emotions, negative emotions, and SNS addiction proneness. Discriminant validity was assessed by low correlation with gratitude. At the end, limitation and suggestions for the future research were discussed.

This study was conducted in order to evaluate validity and reliability of the Korean version scale to measure maternal satisfaction in normal birth(KSMMS-normal birth). The SMMS-normal birth was administered to 205 postnatal women, together with the perception of birth experience scale. An exploratory factor analysis revealed six factors solution for the twenty three-item scale. Confirmatory factor analysis supported good convergent and discriminant validities, and factor correlations ranged from 0.11 to 0.57. The KSMMS-normal birth showed good concurrent validity with the perception of birth experience scale. The Cronbach alpha for the total scale was .91. It ranged between .80 to .90 for six subscales. The KSMMS-normal birth is reliable and valid instrument to measure maternal satisfaction. Therefore this scale can be used to assess maternal satisfaction in normal birth at hospital during the postpartum 2nd and 3rd day.

Self-Compassion(SCS) Scale is developed by Neff(2003a) and translated by Kim, Lee, Cho, Chae, Lee(2008). But, there is the limitation with validation SCS and Korean version Self-Compassion(K-SCS) performed in college students and the incoherence for the results of the scale's factor analysis in other countries. Therefore, this study examined the validity of factor structure in SCS based on data in 435 adult aged from 18 to 79. For this, we conducted exploratory factor analysis(EFA) and confirmatory factor analysis(CFA), and we examined the each adequacy of two-factor, tree-factor and six-factor model. The result of EFA supported six-factor and the result of CFA was the six factor model best as well.

There is more than one way to conduct scientific research. In addressing the concern for educating the gifted in science towards achieving objectives of fostering their research skill, its elements need be explored and discussed by first admitting that various methodologies and features coexist in the name of scientific research. This study explores the various features of research skill presented as scientific process skills focusing on the students' experimental designing. Of course, there are several other domains included facets of research skill, such as problem finding, scientific knowledge, and self-efficacy. A Diet Cola Test (DCT) (Fowler. 1990) for digging into science process skills as an elements of research skills was administered to 705 students from 3rd to 10th grade, who enrolled the gifted education centers in Korea. Date was interpreted and analyzed based on the focus of Science education perspectives and research methods related to creative thinking and problem-based learning. But I eschew establishing and generalizing fixed constitutes of research skill from this research.
