The study examined how changes in time invested in private tutoring and academic achievement influenced each other through a multivariate latent growth model by using the data from the first to the third year presented in the KYPS. This study identifies not only how changes in the private tutoring experience exerted a direct influence on changes in academic achievement, but also measures what kind of changes in private tutoring and academic achievement had emerged over time. The detailed study results are as follows. First, the analysis of time invested in private tutoring showed that the higher the grades, the greater were the amount of time invested in private tutoring in the case of Korean language study. On the other hand, the results showed that in the case of English and mathematics, the higher the grades, the lesser was the amount of time invested in private tutoring. Second, private tutoring and academic achievement were all in a linear relationship. Third, it was shown that the time invested in private tutoring and academic achievement exerted a negative influence on each other according to the passage of time.

To explore effects on each friendship, family, romance, and community in sub-variables of loneliness on academic achievement in science for Y-middle school students, multiple regression analysis is carried out by stepwise method. As the results, I found the following facts. Academic achievement in science for the students was expressed by the following equation. Academic Achievement=48.765+4.012${\times}$[Family](t=2.082, p=.039)-3.957${\times}$[Romance](t=-3.147, p=.002)+5.281${\times}$[Community](t=2.965, p=.003). And each variable value of the explanatory power affecting academic achievement in science for the students is presented in order of community (12.0%), family (6.6%), and romance (6.3%). But the friendship variable is not significant in affecting academic achievement in science.

To analyze the relationships between self-control, thinking quality and mathematical academic achievement, 197 senior school students were asked to complete questionnaires called "self-control ability on mathematics for middle school students" and "thinking quality for senior school students." The results were as follows: (1) There was strongly positive relevance between self-control ability, thinking quality and mathematical academic achievement. (2) A model was presented in which self-control ability had a direct impact on mathematical academic achievement, meanwhile had indirectly influenced mathematical academic achievement by thinking quality which acted as the intermediate variable. Thinking quality had a direct impact on mathematical academic achievement, too. (3) There's no significant difference between the two groups of boys and girls on the structural weights.

This study used Hierarchical Linear Modeling analysis to investigate the effects of individual self-regulated cognitive strategies and public education on middle school students' academic achievement. Participants were 6389 (boys 3287, girls 3102) middle school students from the 2005 data of the Korea Education Longitudinal Study. Results were as follows : (1) there were significant differences among different schools in middle school students' academic achievement, i.e. 20% of variance in English achievement and 15% of variance in mathematics achievement were explained by school differences. (2) Students' elaboration and meta-cognitive strategy influenced academic achievement positively. (3) Predictor variables by ability grouping, supplementary class, and/or self-learning class had no significant effects on students' academic achievement.

This study aims to examine the effects of academic procrastination in middle school students on their academic achievement. It also analyzed the influences of stress level recognized by middle school students on their academic achievement. First, it examined theoretical and preceding studies and assumed that sub-factors of academic procrastination in middle school students such as behavioral, cognitive and emotional factors affected their academic achievement. It was assumed that the middle school students' stress had the direct mediating effects on their academic achievement. As a result of the research, it was found that sub-factors of academic procrastination in middle school students such as behavioral, cognitive and emotional factors had partially direct influence on their stress and academic achievement. It was shown that the analysis of mediating effects from middle school students' stress had no influence on the academic achievement. This study presented policy suggestions of academic achievement in middle school students as an alternative based on the research results.

Objective: The current study aimed at examining the mediation effects of children's self-esteem and self-control in learning between perceived academic achievement at $4^{th}$ grade and $6^{th}$ grade. This article proposes that perceived academic achievement boosts self-esteem and self-control in learning and both in turn, influence subsequent perceived academic achievement. We especially attempted to empirically prove that a serial multiple mediation of self-esteem and self-control in learning between the perceived academic achievement at two time points exists. Methods: We analyzed the longitudinal data of 1,881 children from the $4^{th}$ to the $6^{th}$ wave data of the '2010 Korea Children and Youth Panel Survey (KCYPS)' by means of a Hayes's PROCESS(2012) program. Results: The results revealed that perceived academic achievement at $4^{th}$ grade influenced children's self-esteem and self-control in learning at $5^{th}$ grade. Children' self-esteem and self-control in learning subsequently predicted perceived academic achievement at $6^{th}$ grade. Children's self-esteem significantly predicted self-control in learning supporting the hypothesis of serial multiple mediation. Conclusion/Implications: In conclusion, children's self-esteem and self-control in learning behaviors both mediated the association between perceived academic achievement at $4^{th}$ grade and at $6^{th}$ grade. The findings imply the importance of consideration of both psychosocial and behavioral aspects in understanding the academic performance during childhood.

This study examined the impact of academic achievement and maternal differential treatment on academic self-concept among adolescent siblings. The sample consisted of 438 students attending middle schools in Seoul (M = 15.2 yrs.), who had a sibling. Data were analyzed using Structural Equation Modeling. Academic achievement compared with a sibling and maternal differential treatment had direct effects on academic self-concept, indicating that children with higher academic achievement scores than their sibling and with perceived maternal differential treatment reported a significantly higher academic self-concept. Also, the relationship between academic achievement as compared with a sibling and academic self-concept was mediated by maternal differential treatment. These findings could be used in educational settings as a basis for improving the academic self-concept of early adolescents.

The purpose of the present study is to investigate the factors which affect academic achievements among gifted students' intellectual and personality characteristics. For this purposes, 125 science gifted students' learning ability test and NEO personality test data were collected and analyzed along with the school achievement scores. According to the results of this study, there are significant relationships between academic achievements and conscientiousness, executive function, and learning motivation. Based on the achievement level, there are positive correlation between academic achievement and conscientiousness in a high academic achievement group. For the middle academic achievement group, there are positive relationship with executive function and learning motivation attention but negative relationship with extraversion. For the low achievement group, concentration was the only factor highly correlated with academic achievement. For the high academic achievement group, conscientiousness is a significant predictors of academic achievement; for middle academic achievement group, executive function and learning motivation were the significant predictors; for low academic achievement group, concentration was the significant predictors of academic achievement. Results were discussed in terms of practical value of enhancing gifted students' academic achievement.
