This study examined the characteristics of the National Assessment of Educational Achievement (NAEA) in Science according to gender. It investigated gender achievement differences in the science section of the 2010 NAEA, the ratio of gender difference in achievement, the ratio of correct answers within each content domain and behavioral domain, and the items which showed high differences between males and females. The results indicate first, that, for 9th graders, females outperformed males in academic achievement in science. Second, with respect to the ratio of correct answers, males outperformed females in the advanced and below basic level groups, but females outperformed males in intermediate level groups. Third, females outperformed males in knowledge and inquiry in the behavior domains, and in chemistry and biology in the content domains. Fourth, an analysis of the items showing the largest gender gap indicated that males outperformed females in interpreting data, while females outperformed males in the items concerned with daily life and items related to the memorization of rules. This research on gender differences in science will allow teachers to complement the weaknesses of students when they study science, and support improved instructional methods in science.

The purpose of this study was to investigate eighth graders' scientific method of inquiry used in their reports. We developed a framework, 'Analysis of Scientific Methods and Information Sources', with a perspective of the Nature of Science to analyze students' planning method, data analysis, and information sources. We then compared results with levels of questions to find out whether they affected students' 'Scientific Method'. In addition, we analyzed students' responses of the survey questionnaire, e.g.. how they liked Scientific Method. Results are as follows: First, 'planning method' consisted of 'consultant' and 'activities'. The 'activities' were 'experiment', 'correlational study', and 'observation' Students planned by utilizing 'consultant' more than the other. In case of planning 'activities'. most of them were 'experiment' Second, 'data analysis' consisted of 'summary', 'table', 'chart', 'graph' and so on. Students analyzed their data by using 'summary' frequently. The types of 'summary' were divided into 'simple summary' and 'relational statement' Third, 'information sources' consisted of 'computer', 'library'. and 'professional consultant' Most of the students gathered information from 'computer' Fourth, the types of 'planning method' and 'summary' were affected by the levels of questions. Fifth, some of the students reported their difficulty in 'planning method' because the collected information was less reliable, lacking, and having difficult technical terms.

The purpose of this study was to examine the effects of an empathy training program on the empathy and bullying's degree for bullies. The research hypotheses set to achieve this goal were as follows. 1. An experimental group that gets empathy training might make a better improvement in empathy immediately after the training than a control group that doesn't, and the effect of the training might last till eight weeks later. 2. An experimental group that undergoes empathy training might show a more significant decrease in bullying's degree for bullies immediately after the training than a control group that doesn't, and the effect of the training might last till eight weeks later. The subjects in this study were 20 children who were designated as bullies when 40 fifth graders from Y Elementary school and 31 children from S Elementary school in the city of T, south Gyeongsang province, took K-PNI. Those children were asked to tell about who were attackers and who were victims, and 10 children each were selected from the two elementary schools as bullies, who were respectively selected as an experimental group and a control group. The empathy training program used in this study was prepared by modifying the empathy training programs developed by Shin Gyeong- il(1994). That program was prepared to be appropriate at fifth grader level. To assess how much the selected children bullied their peers, Kim Seok-jin(1999)'s School Bullying Inventory was utilized. Besides, Song Ho-yeon's revised version to assess the change of counselee empathy was employed. In order to analyze the resulte, ANOVA was implemented. The conclusions obtained from the results and discussion of this study are as follows. First, the empathy training program was effective in changing the empathy of the bullies for the better, and their improved empathy remained the same eight weeks later. Second, the empathy training program had an effect in reducing bullying's degree for bullies, and there was no change in their reduced bullying's degree eight weeks later. Third, the empathy training program served to change their neglecting/ ostracizing and ridiculing/teasing behaviors. And the retention test that was implemented eight weeks later showed the effect of training remained unchanged. Fourth, the empathy training program was effective in changing their cursing/threatening actions according to the posttest results, but the retention test showed that its effect didn't keep on. Fifth, the empathy training program didn't bring any changes to their robbing/striking actions either immediately after the training or eight weeks later.

This study examines the structural relationship between parents' positive and negative parenting attitudes, life satisfaction, and academic helplessness. To this end, 2,595 middle school students (1,405 boys and 1,185 girls) were used among the KCYPS 2018 panel materials. The model was validated using a structural equation model, and the verification of the mediated effects of life satisfaction was significant with bootstraps. The results of the study are as follows. First, the positive and negative parenting attitudes of parents have a significant impact on life satisfaction. These results can be interpreted as having an impact on the lives of adolescent children, depending on their parenting attitudes. Second, the positive and negative parenting attitudes of parents have a significant impact on academic helplessness. These results can be interpreted as having an effect on the academic performance of adolescent children depending on their parenting attitudes. Third, satisfaction in life has a significant adverse effect on academic helplessness. These results can be interpreted as having a positive impact on studies according to the satisfaction level of youth's life, and having a negative impact on studies if life satisfaction is high and life satisfaction is low. Fourth, the satisfaction of life is mediated between parents' positive and negative parenting attitudes and academic helplessness. Through this study, it is meaningful in that it allows parents to understand the process of life satisfaction affecting their academic helplessness according to their parenting attitudes.

To extend the potential benefits of error, the current study examined factors that affect students' error perception in classroom. An experimental design was used to measure relations of classroom goal structure, feedback, and social relationships on students' perception of error. A total 316 fourth, fifth, and sixth graders attending elementary schools participated as part of their regular class curriculum. Self-reported questionnaires were administered to measure students' perception of errors and relationships with teacher and peers, then students were manipulated by classroom goal structure and feedback. Results from multiple regression suggest that students' perception of learning from error has affected by relationships with peers at the most, then relationships with teacher and the type of feedback. Students' perception of risk taking for error also affected by relationships with peers and teacher, then the classroom goal structure. However, no classroom goal structure and feedback affect on their perception of thinking about error to improve their learning as well as error strain. These results imply how classroom climate should be structured to improve perception of errors to improve student's learning.

The study conducted a Focus Group Interview (FGI) on college students to identify single-person households and Solitary Deaths of single-person households recognized by college students. This can be provided as basic data to address problems in single-person households and social problems such as future youth solitary death and will contribute to building a social safety net. This study conducted FGI to analyze data for five fourth graders majoring in social welfare. In the case of involuntary independent living, the high poverty and unemployment rate of single-person households was cited as the cause of economic instability, housing problems and emotional relationship formation. He said that he thinks about young loneliness because he has vague fears about what happens in the media and what can happen to them. As the number of young single-person households will inevitably increase in the coming months and economic difficulties are the biggest problem and the biggest cause of young solitude, institutional support is needed first, especially for housing costs.

This study aims to compare student self-, teacher-, and objective assessments of elementary science-gifted students' scientific creativity. A science-gifted program on the topic of Hydraulic Machine was implemented to 40 fifth-graders in the Science-Gifted Education Center of an education office in Seoul, Korea for four weeks. The products of the students' activities were assessed by three types of 'Student Self-Assesment', 'Teacher-Assesment', and 'Objective Assessment using Formula'. Based on two essential components of creativity, the scientific creativity is divided into two parts of originality and usefulness. Ideas that satisfy both components can be counted as scientifically creative. The main results of this study are as follows: First, the scores of each week and the average of the overall four-week scores on scientific creativity were significantly correlated. Student self-assessment (r=.687), teacher-assessment (r=.715), and objective assessment (r=.724) appeared consistently over instructional periods. Second, the average scores of student self-, objective, and teacher-assessments were 73.15, 35.72, and 26.60, respectively. The result of student self-assessment on scientific creativity tended to be higher than those of formula and teacher. Third, among the three types of assessment on scientific creativity, a strong correlation appeared between teacher- and objective assessment (r=.974), but neither between student self- and objective (r=.161) nor between student self- and teacher- (r=.213). Fourth, the scores on originality component had a positive correlation between teacher- and objective assessment (r=.713). The scores of student self- and teacher-assessments had a significant correlation too (r=.315), but not between student self- and objective assessment (r=.279). Fifth, the scores on usefulness component did not have a significant correlation between student self- and teacher-assessment (r=.155). Sixth, there was no significant difference on scientific creativity between student self- and objective assessment [${\chi}^2$(1, n=40)=1.667, p<.197]. Not between student self- and teacher-assessment either [${\chi}^2$(1, n=40)=1.616, p<.204]. On the contrary, there was a significant difference between teacher- and objective assessment [${\chi}^2$(1, n=40)=32.593, p<.000]. Seventh, the students were categorized into four groups according to the levels of their scores by student self- and teacher-assessment. The result showed that factors influencing student self-assessment are inherent in the personality traits of gifted individuals, such as self-esteem and perfectionism. The findings suggested that there are challenges for the educators to make efforts to construct consistent assessment methods for scientific creativity.

This study aims to determine the implications of the efficient and effective implementation of science core competency (ScC) education by examining the state of science core competencies derived from the 2015 revised elementary school science curriculum and analyzing teachers' and students' perceptions. To this end, this paper investigated the reality of reflecting the science core competencies of science textbooks in a group of third and fourth graders from seven elementary schools who passed the test. In addition, in-depth interviews were conducted with four elementary school teachers who participated in qualification textbook selection, and 156 elementary school students were surveyed to determine their perceptions of science core competencies. Findings showed that, first, 1,586 science core competencies were reflected throughout the textbooks, with an average of 227 per textbook and biology being the most salient area. Second, teachers did not understand the difference between previous inquiry activities in textbooks and ScC education. Third, no statistically significant differences were observed in the perceptions of male and female students on science core competencies, the highest average of perceptions being those of scientific thinking ability. From these results, this study concluded that for ScC education to be realized as a curriculum, textbooks must be organized according to the purpose of core competency education, implementing practical changes, and efforts must be directed toward changing the perceptions of individuals who deliver education.
