The purpose of this study was to analyze the characteristics of students' academic achievement of middle school science curriculum achievement standards in the 2009 revised national curriculum and to generate implications for curriculum improvement. Based on the results of the 2015-2018 National Assessment of Educational Achievement (NAEA), we analyzed middle school students' mastery of 84 curriculum achievement standards. In the analysis, we used representative item information by achievement level and correct answer rate and checked the validity of the determination of mastery. According to the results of the analysis, 15 of the 84 achievement standards could not determine the degree of achievement. In science, many achievement standards could be mastered only by above-average group students. By achievement level, there were six achievement standards that advanced achievement-level students did not achieve, 38 achievement standards judged to represent mastery by advanced achievement-level students, 23 achievement standards judged to represent mastery by proficient achievement-level students, and two achievement standards judged to represent mastery by basic achievement-level students. By content area, the number of achievement standards corresponding to advanced and proficient levels was similar in the areas of motion and energy and earth and space domains. In the material and life domains, there were more achievement standards corresponding to advanced levels. Accordingly, it is necessary to reinforce customized teaching and learning activities in relation to achievement standards that were under-achieved.

In this paper, I examine the impacts of father's education, a proxy for family wealth and income, on the individual's education, occupational choice and labor force status. I find that father's education influences the level of individual educational investment and occupational choices directly, whose findings are quite different from those of Blau and Duncan(l967) and Phang and Kim(2000). I also find that father's higher level of education induces an individual to withdraw from the labor force, which results in erosion of inequality among family. Therefore I argue that the inheritance of inequality in family wealth tends to persist, while the erosion of inequality proceeds, as well.

This paper analyzed the current level of the middle school academic achievement in Changwon City and explored the ways for improving academic achievement of the middle school in Changwon City. The data used in the analysis were the results of National Assessment of Educational Achievement of middle school students from 2013 to 2016 which was released on the school's information website(www.schoolinfo.go.kr) First, the analysis found that the academic achievement level of the middle school in Changwon City was not higher than those of Gwangju, Daejeon, and Ulsan, where the population size is similar. Second, the level of academic achievement among middle schools in Changwon City differed by year. Third, the level of academic achievement of middle school in Changwon City differed by district. Fourth, the educational achievement gap among middle schools in Changwon City existed by public and private school, as well as by male school, female school, and male and female Middle School. The paper suggested that schools with low ratio of proficient and above achievement levels should look for ways to raise the percentage of proficient and above achievement levels, and schools with higher rates of below basic achievement should make efforts to solve the problem.

The purpose of this study is to evaluate the status of youth overeducation and to analyze the impact on the wage system, before and after the financial crisis. In this study, we adapt the following method; first, we investigate the year 1996 (before financial crisis) and year 2000 (after financial crisis) data from "the Survey Report on the Wage structure", based on the data from "the Occupational Dictionary" by occupation group. So we could evaluate the difference between the youth over-educational status, before and after financial crisis. Second, we analyze the reason why the difference occurs, with financial crisis dummy variable and other variables such as sex, occupation, industry. Third, we try to find the difference between the impact of the overeducation on the wage rate, before and after financial crisis. The main findings are as follows; first, the degree of overeducation in year 2000 is more than in year 1996. So the financial crisis plays the important role in deepening the degree of overeducation. Second, the wage rate of the overeducated worker is higher than that of the required-educated worker. Also, the both wage rates are increased after financial crisis. However, the difference of both wage rates' has declined over the financial crisis. Such a finding means that even though the both wage rates of the overeducated and the required-educated worker are increased, the wage rate of the required-educated worker has increased much more than that of overeducated worker, after the financial crisis.

This investigation analyzed differences in sexual experiences between general and multi-cultural adolescents using the 7th data of youth health behavior online survey and examined effects of fathers' education and sex education on these differences. Specifically, sexual experiences were assigned as dependent variable, multi-cultural background as independent variable, and fathers' education and sex education as moderating variable. Effects of independent and moderating variables were examined using SPSS 20.0 to perform GLM (General Linear Model). As a result, a main effect of multi-cultural background was verified along with the regulation effects of fathers' education and sex education. Specifically, multi-cultural adolescents had more sexual experiences than general adolescents and the effects of fathers' education and sex education were more significant with multi-cultural adolescents than those with general adolescents. While fathers' education and sex education of general adolescents did not make a big difference in sexual experiences, multi-cultural adolescents whose fathers' education levels were low and those who were not taught sex education had more sexual experiences.

With the prolonged COVID-19, the existing academic gap is widening. The purpose of this study is to provide homeroom teachers with a visual confirmation of the academic achievement gap in grades and classrooms through academic achievement analysis, and to use this to help them design lessons and explore ways to improve the academic achievement gap. The data of students' Korean and math diagnostic evaluation scores at the beginning of the school year were visualized as clusters using the K-means algorithm, and as a result, it was confirmed that a meaningful clusters were formed. In addition, through the results of the teacher interview, it was confirmed that this system was meaningful in improving the academic achievement gap, such as checking the learning level and academic achievement of students, and designing classes such as individual supplementary instruction and level-specific learning. This means that this academic achievement data analysis system helps to improve the academic gap. This study provides practical help to homeroom teachers in exploring ways to improve the academic gap in grades and classes, and is expected to ultimately contribute to improving the academic gap.

In recent years, the problem of academic credential falsification is not simply the manipulation of certificates generated by educational institutions, but also the difficulty of trusting automated relationship verification and verification itself, such as falsely recording completion as graduation while still in school. This is due to the lack of sharing of educational background databases among university institutions and the establishment/operation of independent systems that make it difficult to track educational backgrounds. This study designs and implements an E-AV model for academic credential verification centered on university institutions. It summarizes and stores the linked information on the existing academic background in an encrypted database and implements it with web standard technology considering the compatibility and scalability of the existing system. The results of sample data verification show that it improves safety against forgery and complies with storage space and execution performance. This study aims to contribute to the improvement of online verification services such as academic records management in domestic universities.

기존의 학력인증 서비스는 학교에 직접 방문하거나, 온라인을 통해 종이 증명서를 발급받는다. 하지만 학력인증을 블록체인에 기록하여, 인증 서비스의 비용을 줄이고 절차를 간소화하고자 한다. 더불어, 디지털 증명서를 블록체인에 등록하여 발급해온 증명서의 진위 여부를 확인하는 체제가 잘 갖춰지지 않은 곳에서도 재확인이 필요 없는 서비스를 제공하고자 한다. 블록체인에 증명서를 등록하는 중요한 기능은 '스마트 컨트랙트'를 통해 이루어진다. 매년 졸업요건이 변경된다는 점을 고려하면 스마트 컨트랙트에서 블록체인에 학력인증이 등록되는 조건의 업데이트는 필수불가결이다. 하지만 새로운 스마트 컨트랙트를 배포하는 식의 컨트랙트 업데이트는 여러 문제점들이 있다. 이를 해결하고자 본 논문에서는 proxy contract를 이용한 학력인증 서비스 시스템의 설계를 다루고자 한다.
