The demand for private education in Korea is steadily increasing every year, and the participation rate of private education is increasing as the grade goes down. In order to empirically verify the effectiveness of private education, it is necessary to analyze through longitudinal data that has been mainly investigated over a long period of time. This study investigated the longitudinal changes in mathematics academic achievement and participation time in mathematics private education using longitudinal data from 2013 (4th grade in elementary school) to 2017 (2nd grade in middle school) of the Seoul Education Longitudinal Study. The students were divided into groups in which mathematics academic achievement changed similarly as the grade went up, and the effect of mathematics academic achievement was examined according to the change of participation time in private mathematics education for each group. As a result of the study, it was found that the participation time of private math education of all students continuously increased from the 5th grade of elementary school to the 2nd grade of middle school, and the participation time of private math education by group was different. In addition, the effect of private tutoring by group was different according to the group.

In the current study, answer sheets from 8007 students in 236 Korean schools were selected and analyzed to examine errors that emerge in the process of solving descriptive questions of the National Educational Achievement Assessment in mathematics. Questions used in the analysis were response assessment covering middle school mathematics topics: "mathematical symbols and equations" and "functions." The behavioral domain of the questions was that of "problem solving and computation," which requires establishing an equation for a word problem and allows the calculation of an answer that meets a certain condition. The analysis results revealed various errors in each stage of each question, from understanding to solving; the study attempts to conjecture causes for these errors and draw pedagogical implications.

The purpose of this study was to investigate the effects of using the play with multiplication activities based on Skemp's theory for mathematics achievements and attitudes toward mathematics of elementary school students. For this study, we rearranged Skemp's play activities according to our curriculum in the area of multiplication and applied them to the 2nd grade classes of an elementary school. The plays with multiplication activities were applied to the experimental group while traditional teaching method was used with the current mathematics textbook for the comparative group. We obtained the following conclusions: First, in terms of mathematics achievement, the experimental group who used the plays with multiplication activities based on Skemp's theory didn't show significant difference with the comparative group. Second, it proved that the plays with multiplication activities based on Skemp's theory was more effective for lower level of students than the higher level of students. Third, the plays with multiplication activities based on Skemp's theory have positive effects on improving students' attitudes toward mathematics. We need to use the plays with multiplication activities based on Skemp's theory in the classrooms and find problems with the applying the activities. In addition, we need to develop a more various activities based on Skemp's theory for a better teaching.

This paper aimed to understand current trends in online lectures for Korean SAT based on students' academic performances through a qualitative interview approach. In results, the highest academic performance group showed a good deal of interest and usage in online lectures. This group participants preferred private online lectures to public ones. However, the lowest academic group liked to use public online lectures. The middle academic groups who lived in an expensive area spent a lot of money for tutoring or attending private institutes rather than online lectures. Suggestions are: self-regulated learning is needed, public onilne lectures should have improved contents, and lastly, these online lectures are required to be connected with regular school curriculum.

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.

In this study we desire to deduce implications for mathematics curriculum, teaching- learning, and evaluation from the data of Nation Assessment of Educational Achievement. For this, first we extracted the items written by the same achievement standard over two years from 2010 to 2012. Next we investigated whether the items are the representative items of a certain proficiency level and classified into the case of the items of the same proficiency level and the case of the items of different proficiency levels. Based on these we analysed learning characteristic of the each proficiency level. From the results of the above, we proposed what should be changed in mathematics curriculum, what should be considered in teaching-learning, and what should be paid attention to test item development.

The benefits of teaching learning materials to others have been shown on learning achievement. Anxiety is one of the obstacles in learning and it has been shown that math anxiety is strongly associated with math achievement. Thus, the aim of this study was to investigate whether teaching others benefits math anxiety when university students learn statistics. 59 students who enrolled in statistics class participated and 30 students performed group assignment of teaching peer in a group and 29 students did not. Other than group assignments, the instructor, lectures, assignment of solving the problems, and exams were all the same. The results showed that the math anxiety of students who did group assignments of teaching was decreased at the end the semester. Increased math anxiety yielded negative attitudes toward learning statistics, resulting in poor learning performance. Furthermore, the relationship between math anxiety and the attitudes toward leaning statistics was moderated by teaching others. The results suggest that teaching others has an effect on reducing math anxiety and thus, possibly yield persistent learning gains.

Purpose: The purpose of this study was to investigate the correlation between non-strabismic binocular dysfunctions and academic achievement for primary school children. Methods: A total of 1,123 parents and their children aged 8-13 years responded to the College of Optometrists in Vision Development Quality of Life (COVD-QOL) questionnaire. Among the all participants, 123 children who have ${\geq}20$ of visual symptom scores, no amblyopia, no strabismus, no any ocular and systemic pathology, and no contact lenses wearing were chosen for this study finally. Binocular functions were evaluated for final subjects. Results: Of 123 primary school children who have criteria-eligible symptoms 93 had non-strabismic binocular dysfunctions. Accommodative dysfunction was significantly correlated to subjects of science and English, and vergence dysfunction was also significantly correlated to Korean, mathematics, social science, science and English in the final subjects. Conclusions: Correlations between academic achievement and accommodative/vergence dysfunctions were statistically significant. Therefore, accommodative/vergence dysfunctions may be factors to affect academic achievement.
