This study sets out to assess the scientific literacy of secondary school students and to describe their differences according to gender, grade, course. This study involved 112 middle school students and 213 high school students. Their scientific literacy was measured by the Scientific Literacy Test designed by Manhart (1997). A 70-item multiple-choice test was used to assess their scientific literacy. The constructs of science factor included 36 items making up physical science, life science, and earth science subtests. The social aspects of science factor consisted of 34 items in nature of scientific inquiry/knowledge, science as a human endeavor, science and technology, and societal perspectives. A two-way analysis of variance (ANOVA) and t-test were conducted using the SPSS program. The scientific literacy score of the middle school students was 45.17. There was no significant difference according to gender but boys tended to perform better than girls on both the constructs of science factor and the social aspects of science factor. The scientific literacy score of the high school students was 51.79. There was no significant difference according to gender. But, boys tended to perform better than girls on the constructs of science factor. Girls tended to perform better than boys on the social aspects of science factor. The students taking a course on natural science got statistically higher scores than the students taking a course on humanities. The high school students got statistically higher scores than the middle school students.

Purpose: This study aimed to identify the factors affecting on depression among female middle school students. Methods: A survey was conducted on 217 first and second grade female middle school students in C city. Participants' general characteristics, home environment, level of depression, paternal, maternal, peer attachment, school adjustment were measured by self-reporting questionnaire. With SPSS 18.0 program, measured variables were analyzed and compared using descriptive statistics, t-test, ANOVA, Scheff$\acute{e}$ post hoc test, and stepwise multiple regression analysis. Results: The level of depression among female middle school students were higher among students with lower economic status, second in birth order, and second grade in school. The level of depression was negatively associated with the level of paternal attachment (r=-.522), maternal attachment (r=-.487), peer attachment (r=-.376), relationship with teachers in school adjustment (r=-.274), relationship with friends in school adjustment (r=-.378), classroom behavior (r=-.450), school regulation (r=-.267). About 42% of depression among female middle school students were explained by paternal attachment, relationship with friends in school adjustment, and classroom behavior. Conclusion: Paternal attachment was identified as the most influencing factor on depression among female middle school students. Encouraging paternal involvement in the process of school adjustment might be a useful intervention to decrease depression among middle school girls.

The purpose of this study is to investigate the structural relationships among the attitude toward science and science motivation such as affective characteristics, and self-regulated learning strategy such as cognitive factor of science achievement. 853 middle school students residing in Seoul completed questionnaires about attitude toward science, science motivation, and self-regulated learning strategy. The sample variance-covariance matrix was analysed using AMOS 20.0, and a maximum likelihood minimization function. The results are as follows: First, attitude toward science, science motivation and self-regulated learning strategy of middle school students were all found to have a significant direct effect on science achievement. Second, attitude toward science and science motivation in middle school students has a direct effect on the self-regulated learning strategy. Third, attitude toward science in middle school students has a substantial indirect effect on science achievement mediated by their self-regulated learning strategy. Forth, science motivation in middle school students has indirect effect on science achievement mediated by their self-regulated learning strategy. Therefore, in order to improve science achievement among middle school students, teachers should consider synthetically the affective characteristics such as attitude toward science and science motivation, and cognitive factor such as self-regulated learning strategy.

To establish good dietary behavior for middle school students, this study was conducted to analyze the needs of nutrition education and eating attitudes of 373 middle school students(boys 171, girls 202) in Hwaseong city. Using questionnaires, results were gathered and analyzed. Dietary behavior, food group intake and the needs of nutrition education were scored by a five-point Likert scale. Chi-square and student t-test were done for significant gender difference. The correlation between the needs of nutrition education with dietary behavior and food group intake was obtained by Pearson's r. The dietary attitude of 'try to eat first' and 'eating fast' were higher score in boys than in girls(p<0.05). Most of the students thought they didn't have any nutritional problems(71.8%). Nutrition education was considered necessary(54.9%) for proper growth and development(53.0%) in middle school. But 45.1% of students did not suggest by the reasons of 'short time to change'(28.2%), 'more effective in home'(27.4%). The appropriate time of nutrition education was pre-school(28.2%) or elementary school(27.4%), once a week(boys 51%, girls 71.3%) in frequency(p<0.001), and the information acquired by TV/Radio(30.0%) and internet(26.6%). Students(46.0%) wanted to know about 'growth and nutrition'. They were to learn information on the 'healthy growth'(4.10) and 'adolescent nutrition'(4.03). The vegetables group consumption and the thought of dietary attitude 'try to modify bad eating habits' were correlated with almost all categories of desired nutrition education. Through these results, good eating habits would be attained by nutrition education. A nutrition education program would require an expert teacher for middle school students.

The purpose of this study was to determine factors affecting intention to participate in school breakfast programs of middle and high school students in Seoul using the Theory of Planned Behavior. Out of 2,280 questionnaires distributed to the middle and high school students, 2,060 were returned (90.4% response rate) and 1,799 were analyzed (78.9% analysis rate). To determine factors affecting intention to participate in school breakfast programs, logistic regression analyses were conducted for middle and high school students, respectively. For logistic regression, data of 1,217 out of 1,799 students (637 middle and 580 high school students) were used after excluding 582 students which had an answer 'Not sure' to the question about intention to participate in school breakfast programs. In case of middle school students, male than female students (OR = 1.504), the students who skipped all breakfast (OR = 1.851), who ate breakfast $1{\sim}2$ times (OR = 3.474) or $3{\sim}4$ times (OR = 1.950) than those who ate breakfast everyday during weekdays of the previous week were more likely to participate in school breakfast programs. In case of high school students, male than female (OR = 1.967), the students who skipped all breakfast (OR = 4.187), the students who ate breakfast $1{\sim}2$ times (OR = 3.024) or $3{\sim}4$ times (OR = 2.095) than those who ate breakfast everyday during weekdays of the previous week were more likely to participate in school breakfast programs. In addition, both possibility of middle and high school students' participation in school breakfast programs increased as the satisfaction with school lunch service (OR = 1.704, 1.653) increased. Middle school students who perceived their household income level 'low or middle low' (OR = 1.999) than those who perceived their household income level 'middle' and the students who had more positive 'attitude' (OR = 1.311) toward eating breakfast were more likely to participate in school breakfast programs. However, high school students who had higher 'perceived difficulty in access to breakfast' (OR = 1.370) were more likely to participate in school breakfast programs. The results of this study could be useful data to plan and develop school breakfast programs in Korea.

The purpose of this qualitative case study is to understand how the idea of data view and information graphics is used in the social studios middle school textbooks. Data were collected through national curriculum documents and social studies middle textbooks for 7-9 grades. We set up three questions for this studies; what kinds of information graphics are used in the textbooks, how the graphics are organized in the social studies middle school, and how the 7th social studies curriculum is related with the 7th national mathematics curriculum. Through the data analysis, we found that 1) Photographs, illustrations, information maps, etc., are used and frequencies of their usages are in descending order, 2) double lines graphs, circle graphs, and stripe graphs nip often adopted for the comparison of populations, 3) the relation of the two subjects curricula is not so good, especially in the curriculum steps of information mads scatter diagrams, and comparison of populations. Finally we suggest that new web site of data view or information graphics be provided for two curricula, workshop of information graphics are needed for social studies teachers.
