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.

The purpose of this study is to comparatively analyze academic achievement and class satisfaction in college general mathematics between face-to-face classes and remote classes. For this study, we selected 97 first-year students from three departments of an engineering college at M University. Among the subjects of the study, 39 students in Department A and 36 students in Department B took remote classes using pre-recorded class videos, and 22 students in Department C took face-to-face classes. The subjects of this study were evaluated by one professor as the same type of problem with the same content for the same textbook. Among the subjects of the study, 35 students in department A, 34 students in department B, and 17 students in department C who entered through rolling admissions were collected and homogeneity tests were conducted. And then we analyzed the scores of these students' midterm and final exams for general mathematics in the first semester of 2021. Also, we compared and analyzed the academic achievement and class satisfaction of general mathematics subjects for face-to-face classes and remote classes for all study subjects. The results of this study are as follows. First, there is a significant difference in students' academic achievement of general mathematics between face-to-face classes and remote classes. Second, there is a significant difference in class satisfaction between face-to-face classes and non- face-to-face remote classes.

We investigated the relationship of brain dominance with mathematics and science achievement. The participants were 131 middle school students (male: 74, female: 57). It was found that the above average group in mathematics and science achievement had the highest frequency with left lower brain (LLB) (mathematics: 33.8%, science: 35.0%), whereas the below average group in mathematics and science achievement had the highest frequency with right lower brain (RLB) (mathematics: 38.7%, science: 36.1%). The LLB score showed a significant difference between the above average group and the below average group in science (p<.05). In the correlational analysis, the LLB scores had the highest correlation coefficients (mathematics: r=.28, science: r=.26). The LUB scores had the second highest correlation coefficients (mathematics: r=.18, science: r=.24). These results suggest that LLB and LUB are related to mathematics and science achievement. Therefore, we insist that the assessment of mathematics and science achievement should consider brain dominance.

This study examined the relationships between parenting styles, academic achievement, and behavioral adjustment of adolescents in Korea. Using a sample of 181 parents and their children (13-15 years old), parents completed the Parental Authority Questionnaire and adolescents filled out the Youth Behavior Checklist (CBCL) and provided their school grades. Factor analysis was conducted on the PAQ to confirm the psychometric properties. Hierarchical regression analysis was computed to determine the relationship between maternal and paternal parenting styles, academic performance, and children's internalizing and externalizing behaviors. Regression analysis revealed that mother's authoritative parenting style was positively related with adolescents' grades in English. However, father's permissive was negatively related with adolescents' grades in English, Mathematics, and Science. Mother's permissive parenting styles showed negative effects of internalizing and externalizing behavior problems whereas father's permissive parenting styles showed positive effects of internalizing and externalizing behavior problems.

This study concentrates on investigating teaching methods with which students of a commercial high school, located in a rural district, can improve their attitude toward mathematics. To begin with, this study examines the causes which make the students take negative views against it through a survey of their current attitude toward mathematics; offers a special class for them to develop a positive attitude toward it: and then, figure out how much they change their academic attitude within the class and how much they improve their academic achievement as well. The results can be summarized as follows: First, the experimental groups showed terribly negative attitudes toward mathematics, and their academic achievements were very low compared with students of academic high schools nearby, Second, thanks to the special class given to improve their attitude toward mathematics, the experimental groups ended up taking a meaningful positive attitude toward it and developing their academic achievements in the subject. On the other hand, the controlled groups without any chance to receive special lessons remained unchanged. Therefore, it is indicated that a special lesson, properly provided, would play an important role to improve students' positive attitude toward mathematics and develop their basic academic achievements.

This study set out to analyze the learning types that most students were engaged in after school, to review the efficiency of private education through academic institutions or tutoring, and to examine the directions in the after-school learning in math under the current system. It also aimed to analyze the impacts of those after-school learning activities on school classes and to suggest some plans to help public education get back on the track. In the study the after-school learning activities in the math subject were categorized into taking classes at academic institutions, tutoring, and autonomous learning. The grades of the subject students were compared and analyzed for three semesters to find the directions right for the school classes.

Recently in South Korea, various methods are followed in decreasing educational gap between region and social classes through school education. The National Assessment Educational Achievement(NAEA) intends to strengthen responsibility of school education and manage quality of curriculum. Besides, the NAEA intends to bridge achievement gap which is one of educational gaps by grasping the characteristics of academic ability to guarantee basic academic ability. There is not much research about the educational gap among regional scales. Therefore in this study, to examine the achievement characteristics among regional scales closely, we analyse the 2010, 2011 NAEA results in elementary mathematics subject and explore characteristics of items which have sharp differences between local population sizes. The results of the analysis has been showed that the educational gap between 'big-sized cities' and 'small and midium-sized cities' has been increased, but the overall educational gap among regional scales has been decreased.

The study examined and compared relationships among self-esteem, self-efficacy, and academic achievement of children in poverty and the comparative groups. The subjects of this study were 97 elementary school students who had benefited from the free meal project and 97 students as the comparative group who did not receive the benefit. Descriptive statistics, Cronbach's ${\alpha}$ tests, and multiple regression analysis were employed to analyze the data. The results showed that academic scores of the comparative group were statistically higher than those of children in the poverty group in Korean language, mathematics, science, and sociology. Also, self-esteem of children in the poverty group was lower than that of the comparative group's in terms of leadership and popularity. The poverty group also showed lower self-efficacy in self-regulated efficacy tasks. Finally, multiple regression analysis demonstrated that different sub-factors of self-esteem and self-efficacy predicted the academic achievement of children in poverty group and the comparative groups.

Background and Objectives: To assess the academic performance, communication skills, and psychosocial development of prelingual deaf children with cochlear implants (CIs) attending mainstream schools, and to evaluate the impact of auditory speech perception on their classroom performance. Subjects and Methods: As participant, 67 children with CI attending mainstream schools were included. A survey was conducted using a structured questionnaire on academic performance in the native language, second language, mathematics, social studies, science, art, communication skills, self-esteem, and social relations. Additionally, auditory and speech performances on the last follow-up were reviewed retrospectively. Results: Most implanted children attending mainstream school appeared to have positive self-esteem and confidence, and had little difficulty in conversing in a quiet classroom. Also, half of the implanted children (38/67) scored above average in general academic achievement. However, academic achievement in the second language (English), social studies, and science were usually poorer than general academic achievement. Furthermore, half of the implanted children had difficulty in understanding the class content (30/67) or conversing with peers in a noisy classroom (32/67). These difficulties were significantly associated with poor speech perception. Conclusions: Improving the listening environment for implanted children attending mainstream schools is necessary.
