각 개인이 현재 취득한 외국어 성적을 고려한 상대평가지수 두 가지를 제안하였다. 하나는, 만점까지 남아있는 점수 대비 일정기간 동안 성취한 점수의 상대비로 정의하였고, 다른 하나는 일정기간 동안 점수가 향상된 경우는 단측 상대성취도지수와 동일하게 계산하고, 점수가 퇴보한 경우는 초기점수에서 최저점수를 뺀 값 대비 일정기간동안 감소한 점수의 상대비로 정의하였다. 전자를 단측 상대성취도지수(one-side relative achievement index), 후자를 양측 상대성취도지수(two-side relative achievement index)라 명명하였다. 대체로 음의 성취도에 크게 영향을 받는 단측성취도지수에 비해 양측성취도지수는 변동 폭이 좁고 지수의 값이 -1과 1 사이의 값을 가지므로 해석이 보다 용이하다. 그러나 두 지수 모두 매우 예외적인 경우를 제외하고 대체로 비슷한 결과를 제시하며 총점이나 최고 최저점이 서로 다른 시험들을 동일한 기준으로 비교하는 데 용이한 것을 확인하였다.

We conducted a survey related to study methods to identify the factors that have an influence on the academic achievement of university students and analyzed the results of this survey for correlation with students' GPA, which represents academic achievement. Test preparation and effective study habits were found to be the most important factors in overall student achievement. However, when divided by grade, maintaining health and satisfaction with school life are the most important factors for sophomores. Rather, in grades 3 and 4, time spent maintaining health is negatively reflected in improving academic achievement. Divided into gender, male students review or daily academic effort is an important factor in academic achievement, but in the case of female students, there is no difference in relative academic achievement because the amount of review and academic effort are small. For students who have experienced military service, review and test preparation are important to academic achievement, but for students who have not experienced military service, review has no effect on relative academic achievement.

일정기간동안 성취한 개인의 외국어능력 개별성취도지수로 균일성취도지수와 상대성취도지수를 제안하고 그 특성을 비교하였다. 두 지수 모두 -1 ${\sim}$1의값을 가지며 해석이 용이하다. 또한 최고와 최저 점수가 서로 다른 시험의 성취도를 동시에 비교할 수도 있다. 그러나 상태성취도지수는 각 사람의 초기 평가시점의 점수를 고려한다는 점에서 균일성취도지수보다 합리적인 평가지수이다. 본 연구 결과는 각 학생의 현재 능력을 고려하여 성취도를 측정 비교할 뿐 아니라, 서로 다른 종류의 외국어능력시험결과를 동시에 비교할 유용한 지표를 제시한다.

In order to define their relative influence, this study analyzed causal relationships between academic achievement of elementary school students and such related variables as self-esteem and the psychological and economic environment of the home, including clarification of other significant variables affecting academic achievement. Participants were a sample of 485 5th grade students from 8 elementary schools in Busan. Correlation, analysis of covariance structure modeling, and model-fitness tests were applied to the data. Results indicated that the psychological environment of the home has the most significant influence on the academic achievement of children, and the economic environment of the home and self-esteem have relatively low or indirect influence.

This study aims to investigate relationships among self-directed learning readiness [SDLR], prerequisite mathematics test score and achievement level in college mathematics. For this purpose, the adjusted SDLRS (self-directed learning readiness scale) of Guglielmino's model, the score of mathematics diagnostic assesment and first semester college mathematics score among 424 freshmen students of engineering department of D university in 2011 were used and analyzed. Research results are as follows: Firstly, freshmen of engineering department had average level of SDLR, though they showed relative low level of self-direction, passion and time control ability. Secondly, considering SDLR with the mathematics diagnostic assesment score (3 groups: high, middle, low), there were no statistically significant differences. Thirdly, concerning SDLR according to the achievement level in college mathematics, a group which acquired good achievement showed higher level of SDLR compared with middle or lowachievement group. Differences among three groups were statistically significant. Lastly, there were affirmative relationships between SDLR, mathematics diagnostic assesment score and achievement in college mathematics. Furthermore, mathematics diagnostic assesment score and achievement level in college mathematics were found to be the most closely related. Based on the results, we suggest strategies to elevate SDLR of engineering department students and improve their achievement in college mathematics.

The purpose of this study is to analyze the level of interest in the achievement evaluation system, under the assumption that the teacher is an important element of curriculum. For this study, surveys targeting the 150 middle school teachers from 6 schools in Pusan was conducted. A questionnaire based CBAM model was used as research tools. For data analysis, mean of relative strength by teacher's level of interest was calculated. And MANOVA was used to investigate the difference among level of interest according to teachers' background such as sex, age, career, job position, and the grade they taught. The results of the analysis are summarized as follows. First, the middle school teachers' overall interest for achievement evaluation system is low. Teachers showed a typical pattern appeared in the early stages of change. They have little interest in the achievement evaluation system. And they should try to fix and change the achievement evaluation system rather than cooperate it. Second, as a result of this analysis of the difference according to teachers' background, no significant differences were found in most of the variables. Significant differences were found only in age, career, and job position from step 0. In running the post hoc, teachers who have less careers, lower positions, and younger ages had less interest in achievement evaluation system.

This study aims to examine the effects of high school students' time management behaviors on their satisfaction with educational consumption and school life. Three hundred seventy-six high school students in Seoul participated in this investigation. The SPSS ver. 19.0 program was adopted for the descriptive analysis, factor analysis, Cronbach's ${\alpha}$, and multiple regression analysis. The results of the present study can be summarized as follows: first, the levels of time management behavior, satisfaction with educational consumption at school, and satisfaction with school life were relatively high. Second, an analysis of the relative influence on satisfaction with educational consumption revealed that the students' time management behavior was the most influential factor, followed by academic achievement. As the levels of time management behavior and academic achievement were high, the level of satisfaction with educational consumption was high. Finally, an analysis of the relative influence of satisfaction with school life also revealed that the students' time management behavior was the most influential factor, followed by academic achievement. Based on the findings, that is, the effects of high school students' time management behavior and other involved variables on their satisfaction with educational consumption and school life, a future study can present specific ways to enhance the level of satisfaction with educational consumption and school life.
