The present study tested a multivariate model of direct and indirect influences of family Socioeconomic Status (SES) on children's early reading skills at kindergarten entry. The data used here are from one of the largest national databases in the USA, the Early Childhood Longitudinal Study-Kindergarten cohort (ECLS-K). Utilizing structural equation modeling, the results revealed that a number of factors within parental characteristics, home practices, and SES come together to influence children's early reading skills. SES operated primarily indirectly through home literacy activities and also directly in influencing reading. In addition, parental beliefs about kindergarten readiness mediated the relation between SES and home literacy activities. Thus, SES influenced early reading directly and indirectly, through home literacy activities, and simultaneously, through parental beliefs, which in turn, were associated with home literacy activities that were directly associated with children's reading. The findings emphasized the multiple pathways through which SES is associated with children's reading and the need to search for other mediators of SES influence.

Motivated reasoning refers to biased reasoning that is affected by motivation to achieve a particular result or goal. In this study, we attempted a theoretical study on motivated reasoning that hinders the development of scientific thinking and empirical study on actual context of motivated reasoning in the research experiences of next-generation Korean researchers in the field of science and technology. To be specific, literature reviews were conducted to explore the psychological meaning of motivated reasoning and its negative impact on scientific thinking and science research. To understand the substantial meaning and context of motivated reasoning in the field of real science and technology research, we conducted in-depth interviews with eight graduate students and one young science and technology researcher. As a result of the literature reviews, we found out that motivated reasoning can interfere with the proper theory and data coordination, which is the core process of scientific thinking at the individual level. At the socio-cultural level, it can lead to cessation of constructing scientific knowledge and it can act as a mechanism in the process of using science for specific socio-cultural beliefs or purposes, thereby hindering the development of science and technology based on rationale and objective scientific thinking. Quantitative analysis with in-depth interview data showed that graduate students and the young researcher's experienced motivated reasoning results in trying to protect prior beliefs, make hasty conclusions, protecting socio-cultural belief or rationalizing decisions made by their community. Their motivated reasoning could become an obstacle in constructing valid science and technology knowledge through appropriate theory and evidence coordination. Based on these findings we discussed science education for improving scientific thinking.

Rapid growth of information and communication technology and changes in college student characteristics require for university instructors to diversify instructional improvement efforts. Technological Pedagogical Content Knowledge (TPACK) is a capacity that instructors need to build for making instructional design based on consolidated technology. Accordingly this study explores instructors' awareness of the importance and performance of TPACK and to inquire into their relationships with epistemological beliefs and social support as relevant factors through a survey carried out with 264 instructors. The study has shown that there is a significant difference between college instructors' awareness of the importance of TPACK and their awareness of its performance. Furthermore, it has shown that the awareness of importance and performance of TPACK is significantly related to the social support, and that among the sub-factors of the social support, significant influences are observed from the emotional support on their awareness of the importance of TPACK and from the informational support on their awareness of the performance of TPACK. These results provide fundamental data for measures to develop and support TPACK capacity of college instructors, suggesting that it requires a teaching support strategy to enhance social support for instructors above all things.

Objective: Research on children's death concepts requires an approach considering social and cultural context. A qualitative method is necessary to explore children's cognitive process of understanding death. Thus, this study, to overcome the limitations of the quantitative approach based on the deductive logic led by adult researchers, adopted a qualitative research method. Methods: The data collection, referring to the theories of Corr and Balk (2010) and Smilansky (1987), used Death Concept Questionnaire. Each structured question was followed by open follow-up questions to explore how children understood each concept of death. Results: The results showed that participant children were still lacking in the acquisition of death sub-concepts. The qualitative result from open interview showed how children can and can not acquire the concepts of death. Conclusion/Implications: The study could be used in future development of death education programs for children. Based on the results of this research, it is necessary to develop programs for children's death education, which would help them coping with death related anxiety and loss experiences.

This study examined the effects of constructivist educational beliefs and self-regulated learning skills of children on teacher professional development. The study was conducted by sampling 273 teachers. Three kinds of variables, which included constructivist educational beliefs, self-regulated learning ability, and professional development level were measured and analyzed for this study. The results were as follows. First, early childhood teachers beliefs of constructivist education, self-regulated learning ability and professional development were found to be higher than average. Second, the professional development of early childhood teachers is shown to be correlated with constructivist educational beliefs and self-regulated learning ability. When constructivist educational beliefs and self-regulated learning ability scores increases, the professional development score is high. Third, metacognitive strategies, cognitive strategies and constructivist educational beliefs are factors that predict the professional development of early childhood teachers. According to results of this study, it suggests that constructivist educational beliefs and self-regulated learning ability are important factors to be addressed.

The purposes of this study were (a) to ascertain early childhood teachers' beliefs and practices relative to the developmentally appropriate practices, and (b) to determine the relative differences of child care center teachers' beliefs and practices and kindergarten teachers' beliefs and practices. Although interest in obtaining information regarding teachers' beliefs and practices for developmentally appropriate practices in early childhood education is not new, it has commanded considerable attention recently, reflecting concern about growing fragmentation and discontinuity between the early childhood education and care services. A questionnaire measure of 4-and 5-year-old classroom teachers' beliefs and practices based on the guidelines for developmentally appropriate practices of the National Association for the education of Young children, which was consisted of the Teachers' Beliefs Scale(TBS) and the Instructional activities Scale(IAS), was administered to 215 child care center teachers and 215 kindergarten teachers. Positive correlations were found not only between teachers' beliefs and practices but also between developmentally appropriate belief and activities, and between developmentally inappropriate beliefs and activities. There was significant difference between child center and kindergarten teacher groups on the mean scores of each subscale, revealing that kindergarten group had a greater mean score on both TBS and IAS than child care center group. The results of this study implies that there is a great deal of teaching in either child care centers or kindergartens which is not congruent with developmentally appropriate practice. Also, the information obtained with the questionnaire has supported the contention that early childhood education and care services are need to be amalgamated based on the developmentally appropriate practices.

Different aspects of morality, namely, moral belief, moral judgement and moral behavior have been studied seperately. This study examined the development of these three aspects of morality in relation to internal attribution in one sample. A total of 371, third -and sixth- grade children from Masan city were responded to questionnaires on moral belief, moral judgement, and attibutional tendency. In addition, children's moral behavior was measured by the teachers' 5-item rating scale. As results, there were signigicant but low correlations among three components of morality. There were developmental differences in moral belief and moral judgement but there was no age difference in moral behavior. Compared to third graders, sixth graders were higher in moral judgement but lower in moral belief. Social experience as well as cognitive development on moral relativity could explain this paradoxical developmental trend in moral belief. There was a sex difference only on moral behavior : Girls were rated higher in moral behavior than boys. Internal attribution was significantly correlated with all three aspects of morality, .15 with moral belief, .45 with moral judgement, .14 with moral behavior, respectively. There was a significant developmental difference but no sex difference in attributional tendency: Sixth graders reported higher internal attribution than third graders. However, there was no developmental difference in correlations among internal attribution and three aspects of morality. Most importantly, internal attribution explained morality better than either age -or sex- variable. It was suggested that educational programs on morality need to focus on the internalization of it.

With the development of Internet and popularization of smartphones over recent years, social network services are experiencing rapid growth. On top of this, smartphone gaming market is showing a rapid growth and the use of mobile social games is on the significant rise. The occurrence of game data manipulation targeting these services and personal information leakage is highlighting the importance of social gaming security. This study is intended to propose development plans effective and efficient in social game services by figuring out factors putting effects on security dependent behavior of social game users in Korea and carrying out a practical study on the casual relationship between factors influencing security dependent behavior through recognized behavioral control and attitudes for privacy infringement of these factors. To do this, proposed was a study model in which the HBM(Health Belief Model) allowing the social game user to influence security dependent behavior was expanded and applied as a major variable. To verify the study model of this study practically, a survey was conducted among university students in Seoul-based K University and S University who had experienced using social game services. According to the study findings, firstly, the perceived seriousness turned out to provide positive influence to trust. But, the perceived seriousness turned out not to put positive effects on self-efficacy. Secondly, the perceived probability turned out not to put positive effects on self-efficacy and trust. Thirdly, the perceived gain turned out to put positive effects on self-efficacy and trust. Fourthly, the perceived disorder turned out not to put positive effects on self-efficacy and trust. Fifthly, self-efficacy turned out to put positive effects on trust. But, self-efficacy turned out not to put positive effects on security dependent behavior. Sixthly, trust turned out not to put positive effects on security dependent behavior. This study is intended to make a strategic proposal so that social game users can raise awareness of their level of security perception and security willingness through this.

This study was intended to determine PCK of the middle school science teachers on Mendelian genetics and factors influenced to form their PCKs. Two science teachers with biology major with a teaching experience over 5 years were chosen as the subject. Data were collected by class observation, semi-structured interview, teacher questionnaire survey, Content Representation and Pedagogical and Professional-experience Repertoire. The collected data were analyzed based on Magnusson's PCK for science teaching consisting of five components: (a) the orientation toward teaching science, (b) the knowledge of science curriculum, (c) the knowledge of students' understanding, (d) the knowledge of assessment, and (e) the knowledge and belief in the instructional strategies to teach science. Teachers could have the orientation toward teaching science served as an assisting role to support students' abilities. Both subject teachers seemed to focus on giving lectures. Their efforts to improve students' exploration methods and abilities were not expressed enough in their real classes and they found that students struggled to understand Mendelian genetics. Therefore, they should have explained them in an easier way and worked harder to make their students understood accurately and applied basic and advanced concepts of Mendelian genetics. They found students' preconception and misconception regarding Mendelian genetics and wished to enhance their learning effects by various teaching strategies such as correcting misconception, adding the history of science and simply assessing students' affirmative domains. It was also found that factors influenced to form PCK regarding Mendelian genetics by both teachers were as follows: teacher's personality and endeavor, textbooks and guidance books, schools and their circumstances, teaching experience, experience as a learner, interaction with their colleagues, and university curriculum. Both teachers said that it was important for teachers to make every efforts to give better classes.
