The purposes of this study were to find out the degree of formation of the concept of density for the junior high students. The changing pattern of concept in acquiring the concept of density and the degree of development of INRC transformation ability related to the concept of density were also analyzed according to cognitive level and teaching method. The results of this study were as follows. 1) The experimental group were more effective than control group in the formation of the concept of density. 2) Even though students had been taught the concept of density, the various types of preconception were remained and persisted. Especially, the students at concrete level had persisted misconceptions and these misconceptions had been changed to the other misconceptions. 3) In the degree of the formation of the transformation ability of INRC group related to the concept of density in solid phase, the experimental group developed much better on both the abilities of Reciprocal transformation, Correlative transformation and the abilities to manipulate two variables such as volume and mass than control group. 4) The correlation coefficient between GALT score and achivement of the concept of density was 0.67. The correlation coefficient between achivement of the concept of density and the formation the transformation of INRC group related to the concept of density was 0.78.

The purpose of the present study was to understand the clothing behavior of high school girls, and to analyze the differences of the behavior in accordance with their family self-concept and residential area. The study was implemented through a normative-descriptive survey method using a questionnaire. The survey was conducted in April 2006, and the sample consisted of 462 girls from 5 high schools. The data were analyzed by t-test, factor analysis, and cluster analysis. The results are as follows: I. In general, the family self-concept of high school girls was considerably positive, and the group from the Gangbuk area showed a more positive family self-concept than the group from Gangnam. 2. The group from Gangnam displayed a higher score in conformity, fashionability, and economy than the group from Gangbuk did. In terms of personality, the group from Gangbuk showed a higher score than the group from Gangnam. 3. The group having a more positive family self-concept showed a higher score in aspects of personality and psychological dependency. In the areas of conformity and fashionability, the group having a more positive family self-concept manifested a lower score. 4. In the case of the group having a more positive family self-concept, the girls from Gangnam, more than the group from Gangbuk, evidenced a higher score in conformity and fashionability, but showed a lower score in personality. In the case of the group having a lower score regarding family self-concept, the girls from Gangnam, more than those from Gangbuk, showed a higher score in conformity, fashionability, and economy. On the other hand, the personality score of the girls from Gangnam was lower than that of the Gangbuk group. Considering the results of the study mentioned above, it could be said that the clothing behavior of high school girls is different according to their family self-concept and residential area, and such clothing behavior could be used as a cue to understanding their family self-concept.

This study was designed and undertaken to find out the influence of aerobic dancing on women's body image and self-concept, and to determine that body image is directly related to their self-concept. The data were collected from August 1st to September 30th, 1993. The subjects in this study were 150 women registered at aerobic center in Taejon city over for 4weeks(aerobic dancing group) and 132 women who visited at 3 beauty shop located in Taejon city and did not participate in any sports program over for 4 weeks (genernal group). Data were analysed for mean, $X^2-test$, T-test, ANOVA and Pearson-correlation coefficients using the SPSS program. The results of this study were as follows ; 1. Hypothesis I : 'There will be a difference in body image between aerobic dancing group and general group', was rejected (t=1.46, p>0.05) 2. Hypothesis II : 'There will be a difference in self-concept between aerobic dancing group and general group', was supported (t=2.38, p<0.05) . 3. Hypothesis III : 'The more positive body image will be, the higher self-concept will be', was supported(r=0.3393, p<0.01). 4. In the relationships between the body image and the general characteristics of the subjects, occupation(aerobic dancing group and total group), religion(general group), and marriage status(total group) were statistically significant results. 5. In the ralationships between the self-concept and the general characteristics of the subjects, the relationship between evaluational self-concept and occupation was statistically significant result in the total group, between the cognitive self-concept and occupation was in the general group and total group, and between evaluational self-concept and education was in the aerobic dancing group.

This study investigated the effect of generative concept maps according to learning achievements and cognitive load. A total of 78 students in the first grade of middle school participated in this study. Before the experimental treatment was implemented, students had to fill out a questionnaire assessing prior knowledge. The study was designed where all the students were presented the same learning contents regarding photosynthesis; however, the two experimental groups were provided with different concept map methods: a learner-generative concept map (GCM) and an instructor-provided concept map (PCM). GCM students were asked to make a concept map by themselves in small groups while they are reading material. PCM students were instructed to study in small groups in order to read the material; however, they were provided a concept map developed by their teacher. The control group (CG) had the teacher present the learning contents in traditional lecture format with no accompanying concept map. The results show that there were significant differences in the achievements among the groups. CG showed higher achievement than both the experimental groups. There was also a significant difference in cognitive load. Although the GCM group did not obtain higher achievement than the other groups, the GCM group showed higher mental effort and lower physical fatigue than the other groups. The GCM group might have invested more effort to find and connect ideas when drawing their concept map with peers which is unlike the conditions for the PCM group and CG. In conclusion, we should consider applying GCM in teaching and learning design in order to increase learning achievement and decrease extraneous cognitive load.

Objects : This study was attempted to evaluate the body image and the self concept in high risk adolescents for eating disorders. Methods 589 middle school students were investigated with EAT(Eating Attitude Test) and BITE(Bulimic Investigatory Test Edinburgh) and Schematic Figures(Child/Adolescent Version) and Piers-Harris Self-Concept Scale. According to the score of EAT and BITE, three high risk groups(high EAT group, high BITE group, high EAT & BITE group) were identified. Three groups were examined in terms of sex, weight, self concept and body image. Each group was EAT group, BITE group, EAT & BITE group Results: The results of the study were as follows : 1) EAT & BITE group showed greatest body image distortion. 2) BITE group and EAT & BITE group showed lower score in self concept scale. 3) The majority of EAT group were boys, BITE group and EAT & BITE group were mostly girls. 4) All three high risk groups, especially Bin group, revealed overweight compared with normal control group. Conclusions : High BITE group and high EAT & BITE group could be considered as significantly high risk groups for eating disorders, showing overweight, severe body image distortion, and poor self concept. EAT score alone seemed not to discriminate high risk adolescents for eating disorders.

The purpose of this study was to examine the effects of dramatic play on the hyperactive-children's self concept and their hyperactivities. The subjects for this study were 144 five-year old children of Y kindergarten in Seoul. Through the Teacher-Questionary modified by Koung-ja OH(1986) 26 children were assigned to the experimental group and the control group 13 hyperactivity-children (boy:11 girl:2) in the experimental group had dramatic play of which the main themes were positive self concept formation. but the 13 children(boy:11 girl: 2) in the control group did not any dramatic activities. Experimental procedures for the self concept test and the hyperactivity test were pre-test experimental treatment and 2 times post-test by 2 months. Self concept test used for pre-test and post-test was The data was analysed using t-test and paired t-test. The result are as follows: 1. In the pre-test for self concept the scores of the control group showed higher than that of the expe imental group. But there were significantly increased difference between pre-test and the first post0-test in the experimental group. 2. In the second post-test for self concept of the experimental group after 2 months there were no significant differences between the first post-test and the second post-test. 3. In the hyperactivity test there were no significant differences in the control group,. But the experimental group showed decreased hyperactivities in the first post-test. 4. In the second post-test for the hyperactive-children's hyperactivities in the experimental group after 2 months there were no significant differences between the first post-test and the second post-test The dramatic play influenced on the hyperactive-children's self concept positively and the decrease of hyperactive-children's hyperacivities.

The purpose of this study is to investigate the effect of concept mapping strategies on the learner's achievement and their attitude change in science learning. The subject was 159 male students in a middle school in Seoul. Three experimental groups were instructed with different kinds of teaching methods about the unit of photosynthesis and digestive organs. Group I was instructed with traditional teaching method, GroupII was instructed with guided concept mapping strategy, GroupIII was instructed with student-centered concept mapping strategy. The major findings of this study are as follows. 1. Student-centered concept mapping strategy was observed effective at 0.05 significance level in achievement and retention. 2. Only student-centered concept mapping strategy changed students' attitude toward science learning positively. 3. It was observed that there was very significant correlation between the learning ability and science achievement (p<0.01). 4. Student-centered concept mapping strategy was found effective in upper learning-ability group, and guided concept mapping strategy in middle learning-ability group(p < 0.05). 5. Student-centered concept mapping strategy was effective to the groups of upper and middle learning-ability in changing students' attitude toward science learning(p < 0.05).
