This study investigated science self-efficacy, sources of science self-efficacy, and creative personality by grade and gender. For this study, 495 $3^{rd}-6^{th}$ elementary students were participated. The findings showed that there was no significant difference by grade and gender in science self-efficacy. In sources of science self-efficacy, there was significant differences by gender, but not by grade. $3^{rd}$ and $4^{th}$ graders' scores about 'vicarious experiences' and 'physiological and affective states' were higher than the those of $5^{th}$ and $6^{th}$ graders. Among creative personality, $3^{rd}$ and $4^{th}$ graders' scores about 'motivation' and 'challenge' were higher than those of $5^{th}$ and $6^{th}$ graders. Comparing the scores among sources of science self-efficacy, the mean scores of 'social persuasion' were relatively low than other sources. This showed that praises and encouragement of teacher, parents and friends had not been sufficient. In terms of variables' influences on science self-efficacy, multiple regression results showed that 'mastery experiences' in sources of science self-efficacy had the most explanatory power and 'social persuasion' had the second explanatory power. 'Patience' in creative personality showed the third explanatory power. The variables' influences on science self-efficacy showed differences by grade and gender.

The aim of this study was to identify the differences in cellular phone dependency and its use levels of usage purposes according to children's gender, and also to analyze the differences in individual and interpersonal relations development due to cellular phone dependency in children based on gender. Using the first year data of the Korean Child and Youth Panel Survey(KCYPS) 2010, this study analyzed 1,604 fourth graders who have their own cellular phones. For statistical analysis, descriptive statistics were calculated and mean difference analyses were conducted. The results showed that there was no difference between boys and girls in cellular phone dependency. The girls' total phone use level was higher than that of boys and meaningful gender differences in the phone use levels were found in the five phone usage purposes. In both boys and girls, the higher phone dependency groups demonstrated higher levels of phone use in more than eight usage purposes, lower self-resilience and self-regulating learning ability, and less positive peer and teacher relations. These findings show the importance of being concerned about and educating children in the fourth grade about the proper uses of cellular phones.

With 338 fifth-grade students as subjects, this study examined variations in the relation between school bullying and rejection or acceptance by peers as a function of gender and types of aggression. Results showed that the more a boy bullied other children, the more likely he was to be rejected by peers. The more a girl bullied other children, the more likely she was to be accepted by peers. Girls' aggressive behaviors also contributed to their acceptance by peers. When levels of physical and relational aggression were kept constant, verbal aggression was positively related to peer rejection for boys but negatively related for girls. The use of relational aggression contributed to peer rejection only for girls. The findings provide preliminary bases for understanding bullying. Implications of the gender differences are discussed.

The purpose of this study is to determine the patterns of differences between genders in science achievement. Eleventh grade, 140 female and male students were sampled from a school in Seoul. According to the analysis results of pilot study, 20 items were finally selected for the main study. To sharpen our interpretations of the factors and provide some confirmation, we supplemented the statistical analysis with a more detailed cognitive study of the items using think-aloud protocols and interviews with student test takers. The analysis of this study took into account the different item formats, contexts, and presentation styles. The findings are as follows: First, there was no significant gender difference between multiple-choice and open-ended items. Second, male students achieved significantly better in the context of everyday life in multiple-choice items. Third, male students favored items presented as written texts. Fourth, in problem-solving process, female students tend to apply their science concepts, whereas male students tend to apply their everyday experiences. The results of this investigation indicate that gender difference in science achievement depends heavily on item characteristics.

This paper reports findings from a survey of senior secondary school students' epistemological conceptions of mathematics with the adaption of the instrument of the "Conceptions of Mathematics" - Inventory in China. The survey included a sample of 414 Grade 10 students, 441 Grade 11 students, and 400 Grade 12 students from three provinces. Descriptive statistics, one-way ANOVA, and T-test were employed to analyze data in this study. It was found that senior secondary school students mainly focused on objectivity and reality of mathematics, without highlighting the characteristics of sociality, subjectivity, and creativity of mathematics. In addition, besides gender differences, differences were identified among students from different grades, different areas, taught by teachers with different teaching experience and experience in using reformed curriculum.

This study compared science academic passion between elementary general and science-gifted students. A science academic passion test was conducted for fifth-sixth graders at an elementary school, and two gifted science education institutes in Seoul, with 95 and 92 students selected for the test. The result analysis revealed that the science-gifted students' science intellectual passion was significantly higher than general students, regardless of grade and gender. Also, the scores of general students were high in the order of "harmonious passion," "importance," "like," "time/energy investment," and "obsessive passion." The differences in scores between all sub-domains were statistically substantial. Moreover, there were no considerable differences in scores of the science-gifted students among the "important," "like," and "harmonious passion." However, the scores in these three domains were higher than that of "time/energy investment" and "obsessive passion." In addition, the "time/energy investment" score was higher than that of "obsessive passion." The differences in science academic passion by grade and gender were not statistically significant regardless of whether or not a student was science gifted. These results suggest that science academic passion characterizes science-gifted students rather than personal characteristics such as grade or gender.

This paper reports findings from a written assessment which was designed to investigate Chinese primary school students' understanding of the equal sign and equation structure. The investigation included a sample of 110 Grade 3, 112 Grade 4, and 110 Grade 5 students from four schools in China. Significant differences were identified among the three grades and no gender differences were found. The majority of Grades 3 and 4 students were found to view the equal sign as a place indicator meaning "write the answer here" or "do something like computation", that is, holding an operational view of the equal sign. A part of Grade 5 students were found to be able to interpret the equal sign as meaning "the same as", that is, holding a relational view of the equal sign. In addition, even though it was difficult for Grade 3 students to recognize the underlying structure in arithmetic equation, quite a number of Grades 4 and 5 students were able to recognize the underlying structure on some tasks. Findings in this study suggest that Chinese primary school students demonstrate a relational understanding of the equal sign and a strong structural sense of equations in an earlier grade. Moreover, what found in the study support the argument that students' understanding of the equal sign is influenced by the context in which the equal sign is presented.

Although Internet provides a lot of convenience such as easy accessibility, interactivity, concurrency, openness, subsequent dysfunction causes serious problems. Especially elementary school students are indiscriminately exposed to the problems, and thus information communication ethics education is needed for the students. This study conducted a survey with randomly selected 5th and 6th graders in Chungbuk area, and analyzed 'students' experience and perception related to information dysfunction' and 'their experience and perception related to information & communication ethics education at school'. In addition, for the detailed understanding of students' current status and accompanying instructional approach, an additional analysis was conducted to examine the existence of the difference according to students' gender and grade. As a result, significant differences were found according to students' gender and grade in their experience and perception related to the information dysfunction and information & communication ethics education. Considering such differences according to students' gender and grade, appropriate instructional approach needs to be prepared to satisfy students' needs for more effective information & communication ethics education.

Purpose: This study examined gender differences on Musculoskeletal disease (MSD) medical status, the characteristics of the approved patients in workers, and the factors affected approval. Methods: Claim data for the MSD to the Korea Worker's Compensation & Welfare Services (2011) were employed. The medical status by gender was analyzed using t-test, chi square-test and multivariate logistic regression models. Results: The number of claims for MSD has continuously increased in females but not in males since 2006. The severity measured by the care duration, surgery experience and disability grade has been substantially higher in males than in females. Age, size of company, types of occupation, work duration and the weight of materials handled daily were associated with the approval. When males were considered, the work duration, the weight of materials handled daily and parts of the body were statistically significant predictors of approval in males. In case of female, there were meaningful predictors in types of industry and parts of the body. Conclusion: These findings suggest that gender-specific risk factors of MSD should be measured and the management program for MSD should be developed.
