The purposes of this study were 1) to investigate high school girls' overall clothing satisfac-tion and self concepts, 2) to clarify the relationship between clothing satisfaction and self concept in terms of body cathexis, school achievement and social self-esteem, and 3) to find out the social self-esteem differences among the groups related to the high and low levels of clothing satisfaction, body cathexis as well as school achievement. Body Cathexis was measured by the Secord and Jofrard's Body Cathexis Scale. School achievement and social self-esteem were assessed with the modified questionnaires based on the previous researches. Clothing satisfaction which included 3 aspects was measured by the questionnaires developed for this study. The questionnaire was administered to 464 high school students in Seoul, and the data were aiialyzed by frequency, 1-test, one-way·ANOVA and SNK test, Pearson's product moment correlation and factor analysis. The results of this study were as follows: 1) High-school girls 'body' cathexis showed low levels of mean and distribution, wheareas school achievement and social self-esteem showed high levels of those.2) There werf significant positive correlation between clothing satisfaction and all of the self concept variables. In addition, positive correlation were found among the three self concept variables. 3) Three clothing satisfaction factors were emerged and named as clothing possession, clothing selection ability and parent's clothing restriction. Clothing posses- sion and parent's clothing restriction were generally satisfied. 4) School achievement was the most influencial variable for the level of serial self-esteem. It was thought that body dissatisfac-tion would be relieved by the high clothing satisfaction.

The purpose of this study was to apply the instructional strategies for conceptual change prescribed by Posner et al(1982) to the astronomic content domain taught in the elementary and middle school and to analyze the characteristics of students' knowledge revealed in the test before, during and after the instruction. Also, it was to investigate the intercorrelation of cognitive levels, spatial ability and science achievement. The major findings of this study are as follows: 1. Students had a great variety of misconceptions related to the motion of the moon before the instruction, that is, the phases, the names of phases and the cause of changing phases by the moon's orbit about the earth, the moon's appearance and location at the given time, the relative positions of earth, moon and sun during a lunar eclipse, the cause that a full moon is not at the line of node once a month. In the analysis of students' responses concerning the cause of changing phases of the moon and a lunar eclipse, the results indicate that the great majority of students had rote learning rather than meaningful learning in the middle school. 2. Students' reponses during the instruction concerning the changing phases of the moon and the predictive knowledge about the motions of the earth and the moon were analyzed. 1) According to the results of the test given before and after experiment, after discussion, achievement score of the whole of subjects and groups in both preformal and formal cognitive levels appeared to increase linearly. 2) There was no statistically significant differences of achievement scores before and after experiment, after discussion between preformal group and formal group in cognitive levels. 3. Distribution of achievement scores according to the whole of subjects and groups in preformal and formal cognitive levels shows that there was a statistically significant difference between pretest and posttest. 4. Types of conceptual changes concerning the cause of changing phases of the moon that occurred from pretest to posttest were classified as accommodation, incomplete accommodation, assimilation, no change and no model. Six of the seven students starting instruction with alternative frameworks didn't sustain those alternative models throughout instruction. Five of these six students accommodated completely and the last one partially. Seventy-nine percentage of students taking instruction with fragmental models assimilated correct propositions at the end of the instruction. These results suggest that conceptual change model prescribed by Posner et al(1982) has promised the meaningful learning to students taking with fragmental models, especially in cases where students with misconception enter instruction. 5. High correlation between achievement score of simple-recall items and that of written items in pretest and posttest indicates that the higher students got the score in simple-recall items the better they also performed in written items. However, there was no statistically significant differences among cognitive levels, spatial ability and science achievement in the whole of subjects and groups according to the cognitive levels.

In this study, the achievement standards of the "Construction and Operation of Infomation unit were established as the revision of the middle school Infomatice Curriculum in 2007. Based upon archievement standards, the assessment standards were made. And the exemplification was presented for it. The levels of the achievement unit were set in the small unit level through the understanding and the analysis of the new curriculum. The achievement standards were stated in the point of views of the students. The assessment standards divide students' achievement into three level(high/middle/low) and state each level so that it can guide evaluation of achievement. Considering the education environments, the time of the course, and the students' levels, the achievement and assessment standards can be reconstructed and would be used. Before the application of the revised Informatics curriculum, we intend for the understanding about new curriculum to be improved and for the informatics of educational activities to be advanced in quality.

The aim of the National Assessment of Educational Achievement (NAEA) is to produce specific and reliable resources required for the diagnosis and quality control of teaching and learning by measuring the level of students achievement based on the national curriculum. In 2002, we introduced ‘modified Angoff Method’ to obtain more systematic and rational results about the achievement levels. The result indicated the differences of achievement level according to the differences of sexes. Female students achieved higher scores than male students in Grade 6. Male students achieved higher scores than female students in Grade 9 and 10. Furthermore it disclosed a problematic phenomenon that students in small towns and rural areas showed significantly lower scores in all six sub-areas of Mathematics compared with students in metropolitan and cities. The results from the NAEA listed above could be used as the authentic data for improving national curriculum and teaching and learning methods, the establishment of educational policies, and many other areas.

In this study, we suggest implications for teaching mathematical justification with analysis of 6th grade students' awareness of why they needed mathematical justification and their levels of mathematics justification in Algebra and Geometry. Also how their levels of mathematical justification were related to mathematic achievement. 96% of students thought mathematical justification was needed, the reasons were limited for checking their solutions and answers. The level of mathematical justification in Algebra was higher than in Geometry. Students who had higher mathematic achievement had higher levels of mathematical justification. In conclusion, we searched the possibility of teaching mathematical justification to students, and we found some practical methods for teaching.

The characteristics of the pseudo-conceptual or the pseudo-analytical behaviors according to the achievement level(i.e. advanced group, proficient group, basic group, and below-basic group) in grade 9 are as follows. The pseudo-conceptual or pseudo-analytical behaviors to get credit from teachers become conspicuous in lower achievement level. The high achieving students showed more pseudo-conceptual or pseudo-analytical behaviors without undergoing the process of reflection or control. The proficient group was short of control in computation, and the advanced group didn't control well in representation. The proficient group tended to depend on a past successful algorithm and behave habitually. Therefore, it is needed to teach mathematics according to the characteristic of pseudo-conceptual or pseudo-analytic behaviors shown in each achievement level.

This study analyzed gender differences in variability with the results of National Assessment of Educational Achievement on Mathematics from 2003 to 2006, which subjects are 3rd, 9th and 10th grades. The purpose of the analysis was to explain gender differences in mean of mathematical ability scores from a different angle. The results and conclusions obtained in this study are as follows: First, regardless of grades and mean differences, male assessment scores were consistently more variable than female assessment scores. Second, for same male and female students, scores in later grades were almost consistently more variable than those in earlier grades. Third, for all grades, the ratios of males in an advanced and below-basic levels were generally higher than those of females in the same achievement levels.

In this study, on the basis of the seventh national mathematics curriculum, the achievement standards were developed to specify the objectives and contents of teaching-learning and the assessment standards were also developed to differentiate students' levels of achievement at school mathematics. The achievement standards were developed on the following guidelines; 1) to present the minimum standards based on the national curriculum, 2) to develop the standards based on the order of curriculum, 3) to suggest the minimum but ultimate achievement target, 4) to comprise not only of the intellectual but also of psychological spheres such as knowledge, function, attitude, aptitude, etc., and 5) to suggest the standards comprehensively and concretely. The standards were developed on the basis of the middle areas of contents of the curriculum in order not to be too comprehensive, nor to be too detailed. Learning activities, on the other hand, were provided for the assistance of instructions with emphasis on creativity rather than on the routine instruction. The assessment standards were established based on the following principles; 1) to establish the assessment methods, contents, and situations which are to be used for assessment, 2) to establish the criteria of classifying the assessed into the upper, intermediate and lower levels, 3) to develop the assessment standards in a proportionate balance to achievement standards, 4) to establish the intermediate level as a standard, and 5) to establish the minimum level in the contents, concepts, values and attitudes of basic learning. This study also suggested the exemplary test items including short-answer and open-ended questions while putting emphasis on students' real performance to increase their ability in solving problems rather than in calculating. In addition to the test items, it introduced the grading system developed to grade the items with concrete guidelines and to report students' achievement on doing mathematics.

In this paper, we analyzed the characteristics of the gender difference with the results of National Assessment of Educational Achievement(NAEA) from 2004 to 2006, which subjects are 3rd, 9th and 10th graders. First, we analyzed the characteristics of the achievement by the scale scores, according to years, achievement standards, grades. Second, we surveyed the number of items and ratio which male/female prevails and its characteristics according to grades, difference levels, content areas(i.e., numbers and operations, figures, measurement, probability and statistics, letters and formulas, patterns and function). Furthermore, we perform in-depth analysis of the items which gender difference in correct response proportion is more than 7% and analyze the cause of gender difference of achievement. This paper provides large valid data about gender difference by the results of NAEA. It can give suggestions with regard to policy making.

This study examines how family and school social capital moderate the relation between family income and academic achievement. I use the data from the Korean Educational and Employment Panel(KEEP) on the third year middle school students in 2004. Results show that higher levels of family and school social capital, as well as financial capital such as family income are more positively associated with academic achievement. In addition, family and school social capital are served as moderators of the influences of family income on academic achievement. For example, higher parental concern about children and teacher-student bonding provides an extra boost to the positive relationship between family income and student achievement. Furthermore, lower educational expectations can make the relation between income and achievement negative. These findings underscore the importance of social capital at home and at school as the alternatives to promote academic achievement. In particular, greater concern and support encouraging social capital at home and school should be directed at low-income students who are struggling with academic achievement.
