The TIMSS assessment is conducted every four years, and Korean fourth grade cohort in TIMSS 2011 participated in TIMSS 2015 again as eighth graders, which produced the first achievement data of the cohort group of elementary and middle schools. In this study, in order to investigate the causes of the decline in Korean students' science achievement with grade changes from the fourth to the eighth grade, we analyzed educational context variables such as characteristics of students, teachers, and classroom instructions of the top 5 achievement countries participated in both TIMSS 2011 and TIMSS 2015. According to the results, students' sense of school belonging increased, whereas students' positive attitudes toward science teaching decreased with the grade change from the fourth to the eighth. As for the teacher characteristics, the teacher's professional development activity increased, and the teacher's confidence in science teaching showed similar tendency to the international average. Regarding classroom instruction characteristics, the frequency of inquiry-related science activities was highest at the fourth grade, and lower than the international average at the eighth grade. Based the results, we suggested implications for science teaching and learning as well as further studies including development of differentiated strategy by the school level to improve students' achievement, the necessity of converting into more student-engaging science classes, and the necessity of in-depth study on the teacher related educational contextual variables.

This study aims to find out the determinants of male police officers' investigative behavior(active investigation vs. secondary victimization) of sexual violence. For this purpose, a hypothetical model which explains the relationships among the 5 variables (knowledge of law about the investigative role, perception of the protective & connective role, prejudice against the sexual violence, active investigation, and secondary victimization) was developed. Using the data collected from 354 male police officers of 3 cities in Gyeongnam area, the hypothetical model was tested. For data analysis, a structural equation modeling was used, and the final model was found(CFI=0.947, IFI=0.948, RMSEA=0.048). As a result of analyzing the model, the followings were found: (1) Active investigation was increased by knowledge of law about the investigative role, and perception of the protective & connective role, while decreased by prejudice against the sexual violence. (2) Secondary victimization was decreased by knowledge of law about the investigative role. (3) Prejudice against the sexual violence mediate the effects of knowledge of law about the investigative role, and perception of the protective & connective role on active investigation. (4) Prejudice against the sexual violence was found to have no significant effect on secondary victimization. Based on the findings, multi-educational programs, protocols on investigation of sexual violence, professionalization of the police, and changes in investigation environment as well as a system of collaboration and cooperation between police officer and social worker were suggested as a way to increase active investigation and to decrease secondary victimization.

The Minister of Education has officially announced that the Ministry of Education will promote the integration of early childhood education and care. The core of integration is the integration of kindergartens and child care centers, and it is necessary to develop the specific model, so this study was conducted. After the discussion of integration, the discussion has focused on the "Young Children School", and there were differences of opinion on specific issues. Therefore, this study was conducted to propose the specific model for the "Young Children School" after kindergartens and child care centers were integrated with the Ministry of Education. The research question is to find out what the model of the 0-5-year-old young children school model centered on the Ministry of Education. In this study, assuming that integration of early childhood education and care was realized, a plan for integrating early childhood education institutions by type of establishment was proposed. As a conclusion of this study, first, a model of a 0-5-year-old young children school centered the Ministry of Education under the government responsibility is required. Second, a detailed school model that reflects the characteristics of each type of establishment should be developed. Finally, specific measures such as the reform of the teacher training system, the after-school course operation model, and the integration plan with the office of education and local governments should be presented during the young children school system.

Math and Science Olympians participated in a study of the role of environmental influences in their talent development. The questions they got was about family and school factors contribute / or hinder to the development of their scientific talents, and the parents' child rearing styles. The questionnaires were originally developed by Campbell(1996) for cross-cultural studies. The major findings were as follows: ⑴ The professional job of the Olympians'father, the high SES, Their parents'discovering their child's talents were positive factors, ⑵ Their family support and learning environment were reported strong and positive, especially books and reading atmosphere, ⑶ The Olympians participated in the accelerated and enriched educational programs, ⑷ The quality of the class and the rigidity of the curriculum were hindering factors, ⑸ Their parents'rearing style were permissive, affective, and supportive.

To narrow the educational gap and balance the development of education, the Chinese Ministry of Education and various regional education offices are actively promoting government-funded normal education policies. In this study, the background, purpose, and main contents of government-funded normal education policy were identified through a literature review. Furthermore we tried to make an in-depth understanding of the motivation behind government-funded normal students' admission. The results of the analysis were classified as "unexpected motivation" at the individual level, "interim motivation" at the home and school level, and "mirror motivation" at the national policy and social level. "Parents and teachers' opinions" topped the list, followed by securing teaching positions, double-sided dailies (excluding tuition and dormitory fees, paying living allowances), teacher dominance and social status. Parents and teachers had a strong involvement in the admission of government-funded students. Economic factors are relatively more influential than the ideal job as a teacher, and it seems contrary to the original intention of the policy. In response, efforts should be made such as regarding the guidance of state-funded education policies and vocational identity education.

This study explores and compares Korean and U.S. elementary preservice teachers' analytic approaches of students' addition and subtraction computational strategies. Twenty-six Korean and twenty U.S. elementary preservice teachers participated in the study. Participants were asked to analyze mathematical approaches and errors from students' addition and subtraction operations. Preservice teachers' written documents were analyzed by applying open coding and inductive coding based on the grounded theory. As a result, the pattern of error analysis and interpretation of students' addition computations were similar for both Korean and U.S. preservice teachers whereas there were some differences in the analysis of students' subtraction computations. Both Korean and U.S. preservice teachers had difficulties identifying students' strategies and errors for a complicated and unconventional computational approach. Results also indicated that preservice teachers' noticing and interpretation of students' strategies and errors were influenced by their K-12 mathematics curriculum and teacher education program. This study suggests implications and future directions for teacher education, more contextualized teacher preparation programs and balanced connection to the K-12 curriculum.
