Several studies regarding the effects of academic achievement on mental health problems have been conducted in adolescents but not in elementary school students. Therefore, the aim of the current study was to examine the effects of school achievement on depression in Korean elementary school students. The participants were 1,048, 5th to 6th elementary students in Seoul, Korea. The Spearman correlations between school achievement and depression were -0.31 for boys and -0.37 for girls (p<0.001 for both). After controlling for grader, the family economic status and self-esteem, higher achiever group showed a significantly low risk for depression in boys and girls. This study suggests that the lower school achievement is associated with a depressive mood in Korean elementary students. Therefore, students with lower academic performance are a risk group for depression.

The aim of this study is to elucidate the meaning of school dropout which teenager unmarried mothers have been experiencing. Thus, the researchers conducted in-depth interviews of 6 unmarried mothers to portray vividly their voices and the data were analyzed using a qualitative case study. Acording to the results, the meaning of school dropout of teenager unmarried mothers was redefined as the matter of "identity and status deprivation". Also, their school dropout expediences should be analyzed in the more extended perspective beyond the negative meaning of the existing studies. This meant " the one sided exclusion from academic community." This could be drawn with the implications that the exclusion acted as the inner mechanism of another social exclusion and their school dropout served as the bondages of their lifetime. That is, the problem of school dropout has the meaning of 'the present tense' and 'the future tense' simultaneously. Within this context, the phenomenon in which they experienced was acting as the foundation of a continuous exclusion and discrimination. Also, it was found that our society applied its standards to them unilaterally and they came to live as otherness through their pregnancy. Based on these results, this study has an important significance in that it overcame the limitations of previous research and investigated their subjective worlds.

This article analyzes the academic achievement of students who entered A university from 2011 to 2012 using grade point average (GPA). The purpose of this analysis is to find the relationship between admission factors and academic achievement. Contrary to our expectation, GPA of student selected from KSAT is higher than that of selected from CSAT. So, designing and running university entrance type, it is necessary to consider admission factors deliberately.

학습에 대한 적극적인 참여는 학업에서 중요한 행동이며 높은 학업 참여는 성공적인 학업성취와 밀접한 관계가 있다. 학업 참여는 학자들의 관점에 따라 행동적 참여, 정서적 참여, 인지적 참여로 구분된다. 행동적 참여는 학생들이 실제 학습활동과 과제 수행에 어떻게 참여하는가로 정의한다. 그러나 온라인 학습 환경에서는 학생들의 학습활동을 평가하는 데 어려움이 존재하여 관련된 연구의 필요성이 대두되고 있다. 본 논문에서는 영상 분석을 이용한 양방향 Convolutional LSTM 모델을 기반으로 온라인 수업 상에서 학습활동 중 하나인 손들기 행동을 인식하는 방법을 제안한다. 제안된 방법으로 학습활동 중 하나인 손들기 행동의 인식 정확도는 88%이다.

The purpose of this study is to analyze the effect of the parent's socioeconomic status to the academic achievement, together with the mediation effect of the private education expenditure. The structural equation modeling (SEM) method is used with the survey of private education expenditures data collected by Statistics Korea in 2011. In SEM, the multi-group effect is also analyzed for gender, region and school level. The analysis results show that the high socioeconomic status of parent tends to increase the private education expenditures but does not affect the academic achievement, and there are the significant multi-group effect for gender, region, and school level.

The purpose of this study was to inquire into the structural relations between teacher-student interactions, outcome expectancy, academic engagement which are perceived in a physical education class. To this end, this study selected a total of 442 copies of questionnaires as final valid samples using the convenience sampling method targeting middle school students at 4 schools in metropolitan area. For data processing, this study confirmed the goodness of fit test of the whole model using SPSS 20.0 and AMOS 20.0, and then did hypothesis testing; the study results are as follows: First, proximity, one of subfactor of teacher-student interactions, had significant effects on outcome expectancy and academic engagement whereas influence had no significant effects on it. Second, students' outcome expectancy had significant impacts on their academic engagement. Third, outcome expectancy had mediating effects on relations between teacher-student interactions (proximity) and academic engagement.

This study is to develop and validate the academic motivation scale for medical students(AMSMS) based on self-determination theory. After composing preliminary questions from 74 students, a preliminary and main survey were conducted with 148 and 300 students from September to November 2020. Factor analysis, reliability analysis, and correlation analysis were used. As a result of exploratory and confirmatory factor analysis, construct validity was verified. The fitness index of the five-factor model of amotivation, external regulation, introjected regulation, identified regulation, intrinsic motivation was good. The reliability of each factor was ranged from 0.760 to 0.933. The criterion validity of AMSMS was verified by showing a correlation with academic self-efficacy and school life satisfaction. This results show that the AMSMS is both valid and reliable, and it is expected to be used in research related to academic motivation of medical students in the future.

This study aims to examine the differences in the longitudinal relationship between academic stress, mathematics self-efficacy, and engagement in mathematics class according to the math achievement level. According to the results, academic stress, math self-efficacy, and math class engagement were stable over time for the high and low groups. Also, In the high group, math self-efficacy had a negative longitudinal mediation effect in the influence of academic stress to math class engagement. Whereas, in the low group math class engagement had a positive longitudinal mediation effect in the influence of academic stress to math self-efficacy. This means that the academic stress affects differently according to the math achievement level, and mathematics teachers should reflect these results in their teaching/learning strategies so that students can increase their mathematics self-efficacy along with their engagement in mathematics classes.

Since the characteristics of teachers that affect mathematics academic achievement are constantly changing and affecting mathematics achievement, longitudinal studies that can predict and analyze growth are needed. This study used data from middle and high school students from 2013(first year of middle school) to 2017(second year of high school) of the Seoul Education Longitudibal Study(SELS). By classifying the longitudinal changes in mathematics academic achievement into similar subgroups, the direct influence of teachers' characteristics(professionalism, expectations, academic feedback) perceived by students on the longitudinal changes in mathematics academic achievement was examined. As a result of the study, it was found that the characteristics of mathematics teachers(professional performance, expectation, and academic feedback) in group 1(343 students), which included the top 14.5% of students, did not directly affect longitudinal changes in mathematics academic achievement. Students in the middle 2nd group(745, 32.2%) had academic feedback from the mathematics teacher, and the 2nd group(1225 students) in the lower 53%, which included most of the students, showed that the expectations of the mathematics teacher were the longitudinal mathematics achievement. The change has been shown to have a direct effect. This suggests that support for teaching and learning should also reflect this, as the direct influence of teachers' professionalism, expectations, and academic feedback on longitudinal changes in mathematics academic achievement is different according to the characteristics and dispositions of students.
